## Introduction |
|
8 |
||
9 |
This README file contains build instructions for the |
|
10 |
[OpenJDK](http://openjdk.java.net). Building the source code for the OpenJDK |
|
11 |
requires a certain degree of technical expertise. |

### !!!!!!!!!!!!!!! THIS IS A MAJOR RE-WRITE of this document. !!!!!!!!!!!!! |
|
14 |
||
15 |
Some Headlines: |
|
16 |
||
17 |
* The build is now a "`configure && make`" style build |
|
18 |
* Any GNU make 3.81 or newer should work, except on Windows where 4.0 or newer |
|
19 |
is recommended. |
|
20 |
* The build should scale, i.e. more processors should cause the build to be |
|
21 |
done in less wall-clock time |
|
22 |
* Nested or recursive make invocations have been significantly reduced, |
|
23 |
as has the total fork/exec or spawning of sub processes during the build |
|
24 |
* Windows MKS usage is no longer supported |
|
25 |
* Windows Visual Studio `vsvars*.bat` and `vcvars*.bat` files are run |
|
26 |
automatically |
|
27 |
* Ant is no longer used when building the OpenJDK |
|
28 |
* Use of ALT_* environment variables for configuring the build is no longer |
|
29 |
supported |

61 |
## Use of Mercurial |
|
62 |
||
63 |
The OpenJDK sources are maintained with the revision control system |
|
64 |
[Mercurial](http://mercurial.selenic.com/wiki/Mercurial). If you are new to |
|
65 |
Mercurial, please see the [Beginner Guides](http://mercurial.selenic.com/wiki/ |
|
66 |
BeginnersGuides) or refer to the [Mercurial Book](http://hgbook.red-bean.com/). |
|
67 |
The first few chapters of the book provide an excellent overview of Mercurial, |
|
68 |
what it is and how it works. |
|
69 |
||
70 |
For using Mercurial with the OpenJDK refer to the [Developer Guide: Installing |
|
71 |
and Configuring Mercurial](http://openjdk.java.net/guide/ |
|
72 |
repositories.html#installConfig) section for more information. |
|
73 |
||
74 |
<a name="get_source"></a> |
|
75 |
### Getting the Source |
|
76 |
||
77 |
To get the entire set of OpenJDK Mercurial repositories use the script |
|
78 |
`get_source.sh` located in the root repository: |
|
79 |
||
80 |
hg clone http://hg.openjdk.java.net/jdk9/jdk9 YourOpenJDK |
|
81 |
cd YourOpenJDK |
|
82 |
bash ./get_source.sh |
|
83 |
||
84 |
Once you have all the repositories, keep in mind that each repository is its |
|
85 |
own independent repository. You can also re-run `./get_source.sh` anytime to |
|
86 |
pull over all the latest changesets in all the repositories. This set of |
|
87 |
nested repositories has been given the term "forest" and there are various |
|
88 |
ways to apply the same `hg` command to each of the repositories. For |
|
89 |
example, the script `make/scripts/hgforest.sh` can be used to repeat the |
|
90 |
same `hg` command on every repository, e.g. |
|
91 |
||
92 |
cd YourOpenJDK |
|
93 |
bash ./make/scripts/hgforest.sh status |
|
94 |
||
95 |
<a name="repositories"></a> |
|
96 |
### Repositories |

The set of repositories and what they contain: |
|
99 |
||
100 |
* **. (root)** contains common configure and makefile logic |
|
101 |
* **hotspot** contains source code and make files for building the OpenJDK |
|
102 |
Hotspot Virtual Machine |
|
103 |
* **langtools** contains source code for the OpenJDK javac and language tools |
|
104 |
* **jdk** contains source code and make files for building the OpenJDK runtime |
|
105 |
libraries and misc files |
|
106 |

|
107 |
* **jaxws** contains source code for the OpenJDK JAX-WS functionality |
|
108 |
* **corba** contains source code for the OpenJDK Corba functionality |
|
109 |
* **nashorn** contains source code for the OpenJDK JavaScript implementation |
|
110 |
||
111 |
### Repository Source Guidelines |
|
112 |
||
113 |
There are some very basic guidelines: |
|
114 |
||
115 |
* Use of whitespace in source files (.java, .c, .h, .cpp, and .hpp files) is |
|
116 |
restricted. No TABs, no trailing whitespace on lines, and files should not |
|
117 |
terminate in more than one blank line. |
|
118 |
* Files with execute permissions should not be added to the source |
|
119 |
repositories. |
|
120 |
* All generated files need to be kept isolated from the files maintained or |
|
121 |
managed by the source control system. The standard area for generated files |
|
122 |
is the top level `build/` directory. |
|
123 |
* The default build process should be to build the product and nothing else, |
|
124 |
in one form, e.g. a product (optimized), debug (non-optimized, -g plus |
|
125 |
assert logic), or fastdebug (optimized, -g plus assert logic). |
|
126 |
* The `.hgignore` file in each repository must exist and should include |
|
127 |
`^build/`, `^dist/` and optionally any `nbproject/private` directories. **It |
|
128 |
should NEVER** include anything in the `src/` or `test/` or any managed |
|
129 |
directory area of a repository. |
|
130 |
* Directory names and file names should never contain blanks or non-printing |
|
131 |
characters. |
|
132 |
* Generated source or binary files should NEVER be added to the repository |
|
133 |
(that includes `javah` output). There are some exceptions to this rule, in |
|
134 |
particular with some of the generated configure scripts. |
|
135 |
* Files not needed for typical building or testing of the repository should |
|
136 |
not be added to the repository. |

|
141 |
## Building |
|
142 |
||
143 |
The very first step in building the OpenJDK is making sure the system itself |
|
144 |
has everything it needs to do OpenJDK builds. Once a system is setup, it |
|
145 |
generally doesn't need to be done again. |
|
146 |
||
147 |
Building the OpenJDK is now done with running a `configure` script which will |
|
148 |
try and find and verify you have everything you need, followed by running |
|
149 |
`make`, e.g. |
|
150 |
||
151 |
> **`bash ./configure`** |
|
152 |
> **`make all`** |
|
153 |
||
154 |
Where possible the `configure` script will attempt to located the various |
|
155 |
components in the default locations or via component specific variable |
|
156 |
settings. When the normal defaults fail or components cannot be found, |
|
157 |
additional `configure` options may be necessary to help `configure` find the |
|
158 |
necessary tools for the build, or you may need to re-visit the setup of your |
|
159 |
system due to missing software packages. |
|
160 |
||
161 |
**NOTE:** The `configure` script file does not have execute permissions and |
|
162 |
will need to be explicitly run with `bash`, see the source guidelines. |
|

|
167 |
### System Setup |
|
168 |
||
169 |
Before even attempting to use a system to build the OpenJDK there are some very |
|
170 |
basic system setups needed. For all systems: |
|
171 |
||
172 |
* Be sure the GNU make utility is version 3.81 (4.0 on windows) or newer, e.g. |
|
173 |
run "`make -version`" |
|
174 |
||
175 |
<a name="bootjdk"></a> |
|
176 |
* Install a Bootstrap JDK. All OpenJDK builds require access to a previously |
|
177 |
released JDK called the _bootstrap JDK_ or _boot JDK._ The general rule is |
|
178 |
that the bootstrap JDK must be an instance of the previous major release of |
|
179 |
the JDK. In addition, there may be a requirement to use a release at or |
|
180 |
beyond a particular update level. |
|
181 |
||
182 |
**_Building JDK 9 requires JDK 8. JDK 9 developers should not use JDK 9 as |
|
183 |
the boot JDK, to ensure that JDK 9 dependencies are not introduced into the |
|
184 |
parts of the system that are built with JDK 8._** |
|
185 |
||
186 |
The JDK 8 binaries can be downloaded from Oracle's [JDK 8 download |
|
187 |
site](http://www.oracle.com/technetwork/java/javase/downloads/index.html). |
|
188 |
For build performance reasons it is very important that this bootstrap JDK |
|
189 |
be made available on the local disk of the machine doing the build. You |
|
190 |
should add its `bin` directory to the `PATH` environment variable. If |
|
191 |
`configure` has any issues finding this JDK, you may need to use the |
|
192 |
`configure` option `--with-boot-jdk`. |
|
193 |
||
194 |
* Ensure that GNU make, the Bootstrap JDK, and the compilers are all in your |
|
195 |
PATH environment variable. |
|
196 |
||
197 |
And for specific systems: |
|
198 |
||
199 |
* **Linux** |
|
200 |
||
201 |
Install all the software development packages needed including |
|
202 |
[alsa](#alsa), [freetype](#freetype), [cups](#cups), and |
|
203 |
[xrender](#xrender). See [specific system packages](#SDBE). |
|
204 |
||
205 |
* **Solaris** |
|
206 |
||
207 |
Install all the software development packages needed including [Studio |
|
208 |
Compilers](#studio), [freetype](#freetype), [cups](#cups), and |
|
209 |
[xrender](#xrender). See [specific system packages](#SDBE). |
|
210 |
||
211 |
* **Windows** |
|
212 |
||
213 |
* Install one of [CYGWIN](#cygwin) or [MinGW/MSYS](#msys) |
|
214 |
* Install [Visual Studio 2013](#vs2013) |
|
215 |
||
216 |
* **Mac OS X** |

|
221 |
#### Linux |
|
222 |
||
223 |
With Linux, try and favor the system packages over building your own or getting |
|
224 |
packages from other areas. Most Linux builds should be possible with the |
|
225 |
system's available packages. |
|
226 |
||
227 |
Note that some Linux systems have a habit of pre-populating your environment |
|
228 |
variables for you, for example `JAVA_HOME` might get pre-defined for you to |
|
229 |
refer to the JDK installed on your Linux system. You will need to unset |
|
230 |
`JAVA_HOME`. It's a good idea to run `env` and verify the environment variables |
|
231 |
you are getting from the default system settings make sense for building the |
|
232 |
OpenJDK. |

#### Windows |

311 |
##### Windows Unix Toolkit |
|
312 |
||
313 |
Building on Windows requires a Unix-like environment, notably a Unix-like |
|
314 |
shell. There are several such environments available of which |
|
315 |
[Cygwin](http://www.cygwin.com/) and |
|
316 |
[MinGW/MSYS](http://www.mingw.org/wiki/MSYS) are currently supported for the |
|
317 |
OpenJDK build. One of the differences of these systems from standard Windows |
|
318 |
tools is the way they handle Windows path names, particularly path names which |
|
319 |
contain spaces, backslashes as path separators and possibly drive letters. |
|
320 |
Depending on the use case and the specifics of each environment these path |
|
321 |
problems can be solved by a combination of quoting whole paths, translating |
|
322 |
backslashes to forward slashes, escaping backslashes with additional |
|
323 |
backslashes and translating the path names to their ["8.3" |
|
324 |
version](http://en.wikipedia.org/wiki/8.3_filename). |
|
325 |
||
326 |
<a name="cygwin"></a> |

327 |
###### CYGWIN |
|
328 |
||
329 |
CYGWIN is an open source, Linux-like environment which tries to emulate a |
|
330 |
complete POSIX layer on Windows. It tries to be smart about path names and can |
|
331 |
usually handle all kinds of paths if they are correctly quoted or escaped |
|
332 |
although internally it maps drive letters `<drive>:` to a virtual directory |
|
333 |
`/cygdrive/<drive>`. |
|
334 |
||
335 |
You can always use the `cygpath` utility to map pathnames with spaces or the |
|
336 |
backslash character into the `C:/` style of pathname (called 'mixed'), e.g. |
|
337 |
`cygpath -s -m "<path>"`. |
|
338 |
||
339 |
Note that the use of CYGWIN creates a unique problem with regards to setting |
|
340 |
[`PATH`](#path). Normally on Windows the `PATH` variable contains directories |
|
341 |
separated with the ";" character (Solaris and Linux use ":"). With CYGWIN, it |
|
342 |
uses ":", but that means that paths like "C:/path" cannot be placed in the |
|
343 |
CYGWIN version of `PATH` and instead CYGWIN uses something like |
|
344 |
`/cygdrive/c/path` which CYGWIN understands, but only CYGWIN understands. |
|
345 |
||
346 |
The OpenJDK build requires CYGWIN version 1.7.16 or newer. Information about |
|
347 |
CYGWIN can be obtained from the CYGWIN website at |
|
348 |
[www.cygwin.com](http://www.cygwin.com). |
|
349 |
||
350 |
By default CYGWIN doesn't install all the tools required for building the |
|
351 |
OpenJDK. Along with the default installation, you need to install the following |
|
352 |
tools. |

Note that the CYGWIN software can conflict with other non-CYGWIN software on |

your Windows system. CYGWIN provides a [FAQ](http://cygwin.com/faq/ |
|
423 |
faq.using.html) for known issues and problems, of particular interest is the |
|
424 |
section on [BLODA (applications that interfere with |
|
425 |
CYGWIN)](http://cygwin.com/faq/faq.using.html#faq.using.bloda). |

<a name="msys"></a> |
|
428 |
###### MinGW/MSYS |
|
429 |
||
430 |
MinGW ("Minimalist GNU for Windows") is a collection of free Windows specific |
|
431 |
header files and import libraries combined with GNU toolsets that allow one to |
|
432 |
produce native Windows programs that do not rely on any 3rd-party C runtime |
|
433 |
DLLs. MSYS is a supplement to MinGW which allows building applications and |
|
434 |
programs which rely on traditional UNIX tools to be present. Among others this |
|
435 |
includes tools like `bash` and `make`. See [MinGW/MSYS](http://www.mingw.org/ |
|
436 |
wiki/MSYS) for more information. |
|
437 |
||
438 |
Like Cygwin, MinGW/MSYS can handle different types of path formats. They are |
|
439 |
internally converted to paths with forward slashes and drive letters |
|
440 |
`<drive>:` replaced by a virtual directory `/<drive>`. Additionally, MSYS |
|
441 |
automatically detects binaries compiled for the MSYS environment and feeds them |
|
442 |
with the internal, Unix-style path names. If native Windows applications are |
|
443 |
called from within MSYS programs their path arguments are automatically |
|
444 |
converted back to Windows style path names with drive letters and backslashes |
|
445 |
as path separators. This may cause problems for Windows applications which use |
|
446 |
forward slashes as parameter separator (e.g. `cl /nologo /I`) because MSYS may |
|
447 |
wrongly [replace such parameters by drive letters](http://mingw.org/wiki/ |
|
448 |
Posix_path_conversion). |
|
449 |
||
450 |
In addition to the tools which will be installed by default, you have to |
|
451 |
manually install the `msys-zip` and `msys-unzip` packages. This can be easily |
|
452 |
done with the MinGW command line installer: |
|
453 |
||
454 |
mingw-get.exe install msys-zip |
|
455 |
mingw-get.exe install msys-unzip |
|
456 |
||
457 |
<a name="vs2013"></a> |
|
458 |
##### Visual Studio 2013 Compilers |
|
459 |
||
460 |
The 32-bit and 64-bit OpenJDK Windows build requires Microsoft Visual Studio |
|
461 |
C++ 2013 (VS2013) Professional Edition or Express compiler. The compiler and |
|
462 |
other tools are expected to reside in the location defined by the variable |
|
463 |
`VS120COMNTOOLS` which is set by the Microsoft Visual Studio installer. |
|
464 |
||
465 |
Only the C++ part of VS2013 is needed. Try to let the installation go to the |
|
466 |
default install directory. Always reboot your system after installing VS2013. |
|
467 |
The system environment variable VS120COMNTOOLS should be set in your |
|
468 |
environment. |
|
469 |
||
470 |
Make sure that TMP and TEMP are also set in the environment and refer to |
|
471 |
Windows paths that exist, like `C:\temp`, not `/tmp`, not `/cygdrive/c/temp`, |
|
472 |
and not `C:/temp`. `C:\temp` is just an example, it is assumed that this area |
|
473 |
is private to the user, so by default after installs you should see a unique |
|
474 |
user path in these variables. |

<a name="configure"></a> |
|
484 |
### Configure |
|
485 |
||
486 |
The basic invocation of the `configure` script looks like: |
|
487 |
||
488 |
> **`bash ./configure [options]`** |
|
489 |
||
490 |
This will create an output directory containing the "configuration" and setup |
|
491 |
an area for the build result. This directory typically looks like: |
|
492 |
||
493 |
> **`build/linux-x64-normal-server-release`** |
|
494 |
||
495 |
`configure` will try to figure out what system you are running on and where all |
|
496 |
necessary build components are. If you have all prerequisites for building |
|
497 |
installed, it should find everything. If it fails to detect any component |
|
498 |
automatically, it will exit and inform you about the problem. When this |
|
499 |
happens, read more below in [the `configure` options](#configureoptions). |
|
500 |
||
501 |
Some examples: |
|
502 |
||
503 |
> **Windows 32bit build with freetype specified:** |
|
504 |
> `bash ./configure --with-freetype=/cygdrive/c/freetype-i586 --with-target- |
|
505 |
bits=32` |
|
506 |
||
507 |
> **Debug 64bit Build:** |
|
508 |
> `bash ./configure --enable-debug --with-target-bits=64` |
|
509 |
||
510 |
<a name="configureoptions"></a> |
|
511 |
#### Configure Options |
|
512 |
||
513 |
Complete details on all the OpenJDK `configure` options can be seen with: |
|
514 |
||
515 |
> **`bash ./configure --help=short`** |
|
516 |
||
517 |
Use `-help` to see all the `configure` options available. You can generate any |
|
518 |
number of different configurations, e.g. debug, release, 32, 64, etc. |
|
519 |
||
520 |
Some of the more commonly used `configure` options are: |
|
521 |
||
522 |
> **`--enable-debug`** |
|
523 |
> set the debug level to fastdebug (this is a shorthand for `--with-debug- |
|
524 |
level=fastdebug`) |
|
525 |
||
526 |
<a name="alsa"></a> |
|
527 |
> **`--with-alsa=`**_path_ |
|
528 |
> select the location of the Advanced Linux Sound Architecture (ALSA) |
|
529 |
||
530 |
> Version 0.9.1 or newer of the ALSA files are required for building the |
|
531 |
OpenJDK on Linux. These Linux files are usually available from an "alsa" of |
|
532 |
"libasound" development package, and it's highly recommended that you try |
|
533 |
and use the package provided by the particular version of Linux that you are |
|
534 |
using. |
|
535 |
||
536 |
> **`--with-boot-jdk=`**_path_ |

537 |
> select the [Bootstrap JDK](#bootjdk) |
|

> **`--with-boot-jdk-jvmargs=`**"_args_" |
|
540 |
> provide the JVM options to be used to run the [Bootstrap JDK](#bootjdk) |
|
541 |
||
542 |
> **`--with-cacerts=`**_path_ |
|
543 |
> select the path to the cacerts file. |
|
544 |
||
545 |
> See [Certificate Authority on Wikipedia](http://en.wikipedia.org/wiki/ |
|
546 |
Certificate_Authority) for a better understanding of the Certificate |
|
547 |
Authority (CA). A certificates file named "cacerts" represents a system-wide |
|
548 |
keystore with CA certificates. In JDK and JRE binary bundles, the "cacerts" |
|
549 |
file contains root CA certificates from several public CAs (e.g., VeriSign, |
|
550 |
Thawte, and Baltimore). The source contain a cacerts file without CA root |
|
551 |
certificates. Formal JDK builders will need to secure permission from each |
|
552 |
public CA and include the certificates into their own custom cacerts file. |
|
553 |
Failure to provide a populated cacerts file will result in verification |
|
554 |
errors of a certificate chain during runtime. By default an empty cacerts |
|
555 |
file is provided and that should be fine for most JDK developers. |

### Make |
|
642 |
||
643 |
The basic invocation of the `make` utility looks like: |
|
644 |
||
645 |
> **`make all`** |
|
646 |
||
647 |
This will start the build to the output directory containing the |
|
648 |
"configuration" that was created by the `configure` script. Run `make help` for |
|
649 |
more information on the available targets. |
|
650 |
||
651 |
There are some of the make targets that are of general interest: |
|
652 |
||
653 |
> _empty_ |
|
654 |
> build everything but no images |
|
655 |
||
656 |
> **`all`** |
|
657 |
> build everything including images |
|
658 |
||
659 |
> **`all-conf`** |
|
660 |
> build all configurations |
|
661 |
||
662 |
> **`images`** |
|
663 |
> create complete j2sdk and j2re images |
|
664 |
||
665 |
> **`install`** |
|
666 |
> install the generated images locally, typically in `/usr/local` |
|
667 |
||
668 |
> **`clean`** |
|
669 |
> remove all files generated by make, but not those generated by `configure` |

## Testing |
|
682 |
||
683 |
When the build is completed, you should see the generated binaries and |
|
684 |
associated files in the `j2sdk-image` directory in the output directory. In |
|
685 |
particular, the `build/*/images/j2sdk-image/bin` directory should contain |
|
686 |
executables for the OpenJDK tools and utilities for that configuration. The |
|
687 |
testing tool `jtreg` will be needed and can be found at: [the jtreg |
|
688 |
site](http://openjdk.java.net/jtreg/). The provided regression tests in the |
|
689 |
repositories can be run with the command: |
|
690 |
||
691 |
> **``cd test && make PRODUCT_HOME=`pwd`/../build/*/images/j2sdk-image all``** |

### FAQ |
|
700 |
||
701 |
**Q:** The `generated-configure.sh` file looks horrible! How are you going to |
|
702 |
edit it? |
|
703 |
**A:** The `generated-configure.sh` file is generated (think "compiled") by the |
|
704 |
autoconf tools. The source code is in `configure.ac` and various .m4 files in |
|
705 |
common/autoconf, which are much more readable. |
|
706 |
||
707 |
**Q:** Why is the `generated-configure.sh` file checked in, if it is |
|
708 |
generated? |
|
709 |
**A:** If it was not generated, every user would need to have the autoconf |
|
710 |
tools installed, and re-generate the `configure` file as the first step. Our |
|
711 |
goal is to minimize the work needed to be done by the user to start building |
|
712 |
OpenJDK, and to minimize the number of external dependencies required. |
|
713 |
||
714 |
**Q:** Do you require a specific version of autoconf for regenerating |
|
715 |
`generated-configure.sh`? |
|
716 |
**A:** Yes, version 2.69 is required and should be easy enough to aquire on all |
|
717 |
supported operating systems. The reason for this is to avoid large spurious |
|
718 |
changes in `generated-configure.sh`. |
|
719 |
||
720 |
**Q:** How do you regenerate `generated-configure.sh` after making changes to |
|
721 |
the input files? |
|
722 |
**A:** Regnerating `generated-configure.sh` should always be done using the |
|
723 |
script `common/autoconf/autogen.sh` to ensure that the correct files get |
|
724 |
updated. This script should also be run after mercurial tries to merge |
|
725 |
`generated-configure.sh` as a merge of the generated file is not guaranteed to |
|
726 |
be correct. |
|
727 |
||
728 |
**Q:** What are the files in `common/makefiles/support/*` for? They look like |
|
729 |
gibberish. |
|
730 |
**A:** They are a somewhat ugly hack to compensate for command line length |
|
731 |
limitations on certain platforms (Windows, Solaris). Due to a combination of |
|
732 |
limitations in make and the shell, command lines containing too many files will |
|
733 |
not work properly. These helper files are part of an elaborate hack that will |
|
734 |
compress the command line in the makefile and then uncompress it safely. We're |
|
735 |
not proud of it, but it does fix the problem. If you have any better |
|
736 |
suggestions, we're all ears! :-) |
|
737 |
||
738 |
**Q:** I want to see the output of the commands that make runs, like in the old |
|
739 |
build. How do I do that? |
|
740 |
**A:** You specify the `LOG` variable to make. There are several log levels: |
|
741 |
||
742 |
* **`warn`** -- Default and very quiet. |
|
743 |
* **`info`** -- Shows more progress information than warn. |
|
744 |
* **`debug`** -- Echos all command lines and prints all macro calls for |
|
745 |
compilation definitions. |
|
746 |
* **`trace`** -- Echos all $(shell) command lines as well. |
|
747 |
||
748 |
**Q:** When do I have to re-run `configure`? |
|
749 |
**A:** Normally you will run `configure` only once for creating a |
|
750 |
configuration. You need to re-run configuration only if you want to change any |
|
751 |
configuration options, or if you pull down changes to the `configure` script. |
|
752 |
||
753 |
**Q:** I have added a new source file. Do I need to modify the makefiles? |
|
754 |
**A:** Normally, no. If you want to create e.g. a new native library, you will |
|
755 |
need to modify the makefiles. But for normal file additions or removals, no |
|
756 |
changes are needed. There are certan exceptions for some native libraries where |
|
757 |
the source files are spread over many directories which also contain sources |
|
758 |
for other libraries. In these cases it was simply easier to create include |
|
759 |
lists rather than excludes. |
|
760 |
||
761 |
**Q:** When I run `configure --help`, I see many strange options, like |
|
762 |
`--dvidir`. What is this? |
|
763 |
**A:** Configure provides a slew of options by default, to all projects that |
|
764 |
use autoconf. Most of them are not used in OpenJDK, so you can safely ignore |
|
765 |
them. To list only OpenJDK specific features, use `configure --help=short` |
|
766 |
instead. |
|
767 |
||
768 |
**Q:** `configure` provides OpenJDK-specific features such as `--with- |
|
769 |
builddeps-server` that are not described in this document. What about those? |
|
770 |
**A:** Try them out if you like! But be aware that most of these are |
|
771 |
experimental features. Many of them don't do anything at all at the moment; the |
|
772 |
option is just a placeholder. Others depend on pieces of code or infrastructure |
|
773 |
that is currently not ready for prime time. |
|
774 |
||
775 |
**Q:** How will you make sure you don't break anything? |
|
776 |
**A:** We have a script that compares the result of the new build system with |
|
777 |
the result of the old. For most part, we aim for (and achieve) byte-by-byte |
|
778 |
identical output. There are however technical issues with e.g. native binaries, |
|
779 |
which might differ in a byte-by-byte comparison, even when building twice with |
|
780 |
the old build system. For these, we compare relevant aspects (e.g. the symbol |
|
781 |
table and file size). Note that we still don't have 100% equivalence, but we're |
|
782 |
close. |
|
783 |
||
784 |
**Q:** I noticed this thing X in the build that looks very broken by design. |
|
785 |
Why don't you fix it? |
|
786 |
**A:** Our goal is to produce a build output that is as close as technically |
|
787 |
possible to the old build output. If things were weird in the old build, they |
|
788 |
will be weird in the new build. Often, things were weird before due to |
|
789 |
obscurity, but in the new build system the weird stuff comes up to the surface. |
|
790 |
The plan is to attack these things at a later stage, after the new build system |
|
791 |
is established. |
|
792 |
||
793 |
**Q:** The code in the new build system is not that well-structured. Will you |
|
794 |
fix this? |
|
795 |
**A:** Yes! The new build system has grown bit by bit as we converted the old |
|
796 |
system. When all of the old build system is converted, we can take a step back |
|
797 |
and clean up the structure of the new build system. Some of this we plan to do |
|
798 |
before replacing the old build system and some will need to wait until after. |
|
799 |
||
800 |
**Q:** Is anything able to use the results of the new build's default make |
|
801 |
target? |
|
802 |
**A:** Yes, this is the minimal (or roughly minimal) set of compiled output |
|
803 |
needed for a developer to actually execute the newly built JDK. The idea is |
|
804 |
that in an incremental development fashion, when doing a normal make, you |
|
805 |
should only spend time recompiling what's changed (making it purely |
|
806 |
incremental) and only do the work that's needed to actually run and test your |
|
807 |
code. The packaging stuff that is part of the `images` target is not needed for |
|
808 |
a normal developer who wants to test his new code. Even if it's quite fast, |
|
809 |
it's still unnecessary. We're targeting sub-second incremental rebuilds! ;-) |
|
810 |
(Or, well, at least single-digit seconds...) |
|
811 |
||
812 |
**Q:** I usually set a specific environment variable when building, but I can't |
|
813 |
find the equivalent in the new build. What should I do? |
|
814 |
**A:** It might very well be that we have neglected to add support for an |
|
815 |
option that was actually used from outside the build system. Email us and we |
|
816 |
will add support for it! |

### Build Performance Tips |
|
820 |
||
821 |
Building OpenJDK requires a lot of horsepower. Some of the build tools can be |
|
822 |
adjusted to utilize more or less of resources such as parallel threads and |
|
823 |
memory. The `configure` script analyzes your system and selects reasonable |
|
824 |
values for such options based on your hardware. If you encounter resource |
|
825 |
problems, such as out of memory conditions, you can modify the detected values |
|
826 |
with: |
|
827 |
||
828 |
* **`--with-num-cores`** -- number of cores in the build system, e.g. |
|
829 |
`--with-num-cores=8` |
|
830 |
* **`--with-memory-size`** -- memory (in MB) available in the build system, |
|
831 |
e.g. `--with-memory-size=1024` |
|
832 |
||
833 |
It might also be necessary to specify the JVM arguments passed to the Bootstrap |
|
834 |
JDK, using e.g. `--with-boot-jdk-jvmargs="-Xmx8G -enableassertions"`. Doing |
|
835 |
this will override the default JVM arguments passed to the Bootstrap JDK. |
|
836 |
||
837 |
One of the top goals of the new build system is to improve the build |
|
838 |
performance and decrease the time needed to build. This will soon also apply to |
|
839 |
the java compilation when the Smart Javac wrapper is fully supported. |
|
840 |
||
841 |
At the end of a successful execution of `configure`, you will get a performance |
|
842 |
summary, indicating how well the build will perform. Here you will also get |
|
843 |
performance hints. If you want to build fast, pay attention to those! |
|
844 |
||
845 |
#### Building with ccache |
|
846 |
||
847 |
The OpenJDK build supports building with ccache when using gcc or clang. Using |
|
848 |
ccache can radically speed up compilation of native code if you often rebuild |
|
849 |
the same sources. Your milage may vary however so we recommend evaluating it |
|
850 |
for yourself. To enable it, make sure it's on the path and configure with |
|
851 |
`--enable-ccache`. |
|
852 |
||
853 |
#### Building on local disk |
|
854 |
||
855 |
If you are using network shares, e.g. via NFS, for your source code, make sure |
|
856 |
the build directory is situated on local disk. The performance penalty is |
|
857 |
extremely high for building on a network share, close to unusable. |
|
858 |
||
859 |
#### Building only one JVM |
|
860 |
||
861 |
The old build builds multiple JVMs on 32-bit systems (client and server; and on |
|
862 |
Windows kernel as well). In the new build we have changed this default to only |
|
863 |
build server when it's available. This improves build times for those not |
|
864 |
interested in multiple JVMs. To mimic the old behavior on platforms that |
|
865 |
support it, use `--with-jvm-variants=client,server`. |
|
866 |
||
867 |
#### Selecting the number of cores to build on |
|
868 |
||
869 |
By default, `configure` will analyze your machine and run the make process in |
|
870 |
parallel with as many threads as you have cores. This behavior can be |
|
871 |
overridden, either "permanently" (on a `configure` basis) using |
|
872 |
`--with-num-cores=N` or for a single build only (on a make basis), using |
|
873 |
`make JOBS=N`. |
|
874 |
||
875 |
If you want to make a slower build just this time, to save some CPU power for |
|
876 |
other processes, you can run e.g. `make JOBS=2`. This will force the makefiles |
|
877 |
to only run 2 parallel processes, or even `make JOBS=1` which will disable |
|
878 |
parallelism. |
|
879 |
||
880 |
If you want to have it the other way round, namely having slow builds default |
|
881 |
and override with fast if you're impatient, you should call `configure` with |
|
882 |
`--with-num-cores=2`, making 2 the default. If you want to run with more cores, |
|
883 |
run `make JOBS=8` |
|

### Troubleshooting |
|
887 |
||
888 |
#### Solving build problems |
|
889 |
||
890 |
If the build fails (and it's not due to a compilation error in a source file |
|
891 |
you've changed), the first thing you should do is to re-run the build with more |
|
892 |
verbosity. Do this by adding `LOG=debug` to your make command line. |
|
893 |
||
894 |
The build log (with both stdout and stderr intermingled, basically the same as |
|
895 |
you see on your console) can be found as `build.log` in your build directory. |
|
896 |
||
897 |
You can ask for help on build problems with the new build system on either the |
|
898 |
[build-dev](http://mail.openjdk.java.net/mailman/listinfo/build-dev) or the |
|
899 |
[build-infra-dev](http://mail.openjdk.java.net/mailman/listinfo/build-infra-dev) |
|
900 |
mailing lists. Please include the relevant parts of the build log. |
|
901 |
||
902 |
A build can fail for any number of reasons. Most failures are a result of |
|
903 |
trying to build in an environment in which all the pre-build requirements have |
|
904 |
not been met. The first step in troubleshooting a build failure is to recheck |
|
905 |
that you have satisfied all the pre-build requirements for your platform. |
|
906 |
Scanning the `configure` log is a good first step, making sure that what it |
|
907 |
found makes sense for your system. Look for strange error messages or any |
|
908 |
difficulties that `configure` had in finding things. |
|
909 |
||
910 |
Some of the more common problems with builds are briefly described below, with |
|
911 |
suggestions for remedies. |
|
912 |
||
913 |
* **Corrupted Bundles on Windows:** |
|
914 |
Some virus scanning software has been known to corrupt the downloading of |
|
915 |
zip bundles. It may be necessary to disable the 'on access' or 'real time' |
|
916 |
virus scanning features to prevent this corruption. This type of 'real time' |
|
917 |
virus scanning can also slow down the build process significantly. |
|
918 |
Temporarily disabling the feature, or excluding the build output directory |
|
919 |
may be necessary to get correct and faster builds. |
|
920 |
||
921 |
* **Slow Builds:** |
|
922 |
If your build machine seems to be overloaded from too many simultaneous C++ |
|
923 |
compiles, try setting the `JOBS=1` on the `make` command line. Then try |
|
924 |
increasing the count slowly to an acceptable level for your system. Also: |
|
925 |
||
926 |
Creating the javadocs can be very slow, if you are running javadoc, consider |
|
927 |
skipping that step. |
|
928 |
||
929 |
Faster CPUs, more RAM, and a faster DISK usually helps. The VM build tends |
|
930 |
to be CPU intensive (many C++ compiles), and the rest of the JDK will often |
|
931 |
be disk intensive. |
|
932 |
||
933 |
Faster compiles are possible using a tool called |
|
934 |
[ccache](http://ccache.samba.org/). |
|
935 |
||
936 |
* **File time issues:** |
|
937 |
If you see warnings that refer to file time stamps, e.g. |
|
938 |
||
939 |
> _Warning message:_ ` File 'xxx' has modification time in the future.` |
|
940 |
> _Warning message:_ ` Clock skew detected. Your build may be incomplete.` |
|
941 |
||
942 |
These warnings can occur when the clock on the build machine is out of sync |
|
943 |
with the timestamps on the source files. Other errors, apparently unrelated |
|
944 |
but in fact caused by the clock skew, can occur along with the clock skew |
|
945 |
warnings. These secondary errors may tend to obscure the fact that the true |
|
946 |
root cause of the problem is an out-of-sync clock. |
|
947 |
||
948 |
If you see these warnings, reset the clock on the build machine, run |
|
949 |
"`gmake clobber`" or delete the directory containing the build output, and |
|
950 |
restart the build from the beginning. |
|
951 |

* **Error message: `Trouble writing out table to disk`** |
|
953 |
Increase the amount of swap space on your build machine. This could be |
|
954 |
caused by overloading the system and it may be necessary to use: |
|
955 |
||
956 |
> `make JOBS=1` |
|
957 |
||
958 |
to reduce the load on the system. |
|
959 |
||
960 |
* **Error Message: `libstdc++ not found`:** |
|
961 |
This is caused by a missing libstdc++.a library. This is installed as part |
|
962 |
of a specific package (e.g. libstdc++.so.devel.386). By default some 64-bit |
|
963 |
Linux versions (e.g. Fedora) only install the 64-bit version of the |
|
964 |
libstdc++ package. Various parts of the JDK build require a static link of |
|
965 |
the C++ runtime libraries to allow for maximum portability of the built |
|
966 |
images. |
|
967 |
||
968 |
* **Linux Error Message: `cannot restore segment prot after reloc`** |
|
969 |
This is probably an issue with SELinux (See [SELinux on |
|
970 |
Wikipedia](http://en.wikipedia.org/wiki/SELinux)). Parts of the VM is built |
|
971 |
without the `-fPIC` for performance reasons. |
|
972 |
||
973 |
To completely disable SELinux: |
|
974 |
||
975 |
1. `$ su root` |
|
976 |
2. `# system-config-securitylevel` |
|
977 |
3. `In the window that appears, select the SELinux tab` |
|
978 |
4. `Disable SELinux` |
|
979 |
||
980 |
Alternatively, instead of completely disabling it you could disable just |
|
981 |
this one check. |
|
982 |
||
983 |
1. Select System->Administration->SELinux Management |
|
984 |
2. In the SELinux Management Tool which appears, select "Boolean" from the |
|
985 |
menu on the left |
|
986 |
3. Expand the "Memory Protection" group |
|
987 |
4. Check the first item, labeled "Allow all unconfined executables to use |
|
988 |
libraries requiring text relocation ..." |
|
989 |
||
990 |
* **Windows Error Messages:** |
|
991 |
`*** fatal error - couldn't allocate heap, ... ` |
|
992 |
`rm fails with "Directory not empty"` |
|
993 |
`unzip fails with "cannot create ... Permission denied"` |
|
994 |
`unzip fails with "cannot create ... Error 50"` |

## Appendix B: GNU make |
|
1009 |
||
1010 |
The Makefiles in the OpenJDK are only valid when used with the GNU version of |
|
1011 |
the utility command `make` (usually called `gmake` on Solaris). A few notes |
|
1012 |
about using GNU make: |
|
1013 |
||
1014 |
* You need GNU make version 3.81 or newer. On Windows 4.0 or newer is |
|
1015 |
recommended. If the GNU make utility on your systems is not of a suitable |
|
1016 |
version, see "[Building GNU make](#buildgmake)". |
|
1017 |
* Place the location of the GNU make binary in the `PATH`. |
|
1018 |
* **Solaris:** Do NOT use `/usr/bin/make` on Solaris. If your Solaris system |
|
1019 |
has the software from the Solaris Developer Companion CD installed, you |
|
1020 |
should try and use `gmake` which will be located in either the `/usr/bin`, |
|
1021 |
`/opt/sfw/bin` or `/usr/sfw/bin` directory. |
|
1022 |
* **Windows:** Make sure you start your build inside a bash shell. |
|
1023 |
* **Mac OS X:** The XCode "command line tools" must be installed on your Mac. |
|
1024 |
||
1025 |
Information on GNU make, and access to ftp download sites, are available on the |
|
1026 |
[GNU make web site ](http://www.gnu.org/software/make/make.html). The latest |
|
1027 |
source to GNU make is available at |
|
1028 |
[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). |

1031 |
### Building GNU make |
|
1032 |
||
1033 |
First step is to get the GNU make 3.81 or newer source from |
|
1034 |
[ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). Building is a |
|
1035 |
little different depending on the OS but is basically done with: |
|
1036 |
||
1037 |
bash ./configure |
|
1038 |
make |
|

## Appendix C: Build Environments |
|
1044 |
||
1045 |
### Minimum Build Environments |
|
1046 |
||
1047 |
This file often describes specific requirements for what we call the "minimum |
|
1048 |
build environments" (MBE) for this specific release of the JDK. What is listed |
|
1049 |
below is what the Oracle Release Engineering Team will use to build the Oracle |
|
1050 |
JDK product. Building with the MBE will hopefully generate the most compatible |
|
1051 |
bits that install on, and run correctly on, the most variations of the same |
|
1052 |
base OS and hardware architecture. In some cases, these represent what is often |
|
1053 |
called the least common denominator, but each Operating System has different |
|
1054 |
aspects to it. |
|
1055 |
||
1056 |
In all cases, the Bootstrap JDK version minimum is critical, we cannot |
|
1057 |
guarantee builds will work with older Bootstrap JDK's. Also in all cases, more |
|
1058 |
RAM and more processors is better, the minimums listed below are simply |
|
1059 |
recommendations. |
|
1060 |
||
1061 |
With Solaris and Mac OS X, the version listed below is the oldest release we |
|
1062 |
can guarantee builds and works, and the specific version of the compilers used |
|
1063 |
could be critical. |
|
1064 |
||
1065 |
With Windows the critical aspect is the Visual Studio compiler used, which due |
|
1066 |
to it's runtime, generally dictates what Windows systems can do the builds and |
|
1067 |
where the resulting bits can be used. |
|
1068 |
||
1069 |
**NOTE: We expect a change here off these older Windows OS releases and to a |
|
1070 |
'less older' one, probably Windows 2008R2 X64.** |
|
1071 |
||
1072 |
With Linux, it was just a matter of picking a stable distribution that is a |
|
1073 |
good representative for Linux in general. |
|
1074 |
||
1075 |
It is understood that most developers will NOT be using these specific |
|
1076 |
versions, and in fact creating these specific versions may be difficult due to |
|
1077 |
the age of some of this software. It is expected that developers are more often |
|
1078 |
using the more recent releases and distributions of these operating systems. |
|
1079 |
||
1080 |
Compilation problems with newer or different C/C++ compilers is a common |
|
1081 |
problem. Similarly, compilation problems related to changes to the |
|
1082 |
`/usr/include` or system header files is also a common problem with older, |
|
1083 |
newer, or unreleased OS versions. Please report these types of problems as bugs |
|
1084 |
so that they can be dealt with accordingly. |

### Specific Developer Build Environments |
|
1160 |
||
1161 |
We won't be listing all the possible environments, but we will try to provide |
|
1162 |
what information we have available to us. |
|
1163 |
||
1164 |
**NOTE: The community can help out by updating this part of the document.** |
|
1165 |
||
1166 |
#### Fedora |
|
1167 |
||
1168 |
After installing the latest [Fedora](http://fedoraproject.org) you need to |
|
1169 |
install several build dependencies. The simplest way to do it is to execute the |
|
1170 |
following commands as user `root`: |
|
1171 |
||
1172 |
yum-builddep java-1.7.0-openjdk |
|
1173 |
yum install gcc gcc-c++ |
|
1174 |
||
1175 |
In addition, it's necessary to set a few environment variables for the build: |
|
1176 |
||
1177 |
export LANG=C |
|
1178 |
export PATH="/usr/lib/jvm/java-openjdk/bin:${PATH}" |
|
1179 |
||
1180 |
#### CentOS 5.5 |
|
1181 |
||
1182 |
After installing [CentOS 5.5](http://www.centos.org/) you need to make sure you |
|
1183 |
have the following Development bundles installed: |
|
1184 |
||
1185 |
* Development Libraries |
|
1186 |
* Development Tools |
|
1187 |
* Java Development |
|
1188 |
* X Software Development (Including XFree86-devel) |
|
1189 |
||
1190 |
Plus the following packages: |
|
1191 |
||
1192 |
* cups devel: Cups Development Package |
|
1193 |
* alsa devel: Alsa Development Package |
|
1194 |
* Xi devel: libXi.so Development Package |
|
1195 |
||
1196 |
The freetype 2.3 packages don't seem to be available, but the freetype 2.3 |
|
1197 |
sources can be downloaded, built, and installed easily enough from [the |
|
1198 |
freetype site](http://downloads.sourceforge.net/freetype). Build and install |
|
1199 |
with something like: |
|
1200 |
||
1201 |
bash ./configure |
|
1202 |
make |
|
1203 |
sudo -u root make install |
|
1204 |
||
1205 |
Mercurial packages could not be found easily, but a Google search should find |
|
1206 |
ones, and they usually include Python if it's needed. |
