You'll need the following four JAR files:
|
|
|
15 |

|
|
|
16 |
jibx-bind.jar
|
|
|
17 |
jibx-run.jar
|
|
|
18 |
xpp3.jar
|
|
|
19 |
Set the environment variable ALT_JIBX_LIBS_PATH to the location of
|
|
|
20 |
these JAR files.
|
|
|
21 |
|
|
|
22 |
3. Download and install the Binary Plugs for the most recent JDK7 from
|
|

|
23 |
http://download.java.net/openjdk/jdk7/
|
|
|
24 |
Set the environment variable ALT_BINARY_PLUGS_PATH to the location of
|
|
|
25 |
these binary plugs.
|
|
|
26 |
|
|
2658
|
27 |
4. Either download and install the latest JDK7 from
|
|
2
|
28 |
http://download.java.net/openjdk/jdk7/, or build your own complete
|
|
|
29 |
OpenJDK7 by using the top level Makefile in the OpenJDK Mercurial forest.
|
|
|
30 |
Set the environment variable ALT_JDK_IMPORT_PATH to the location of
|
|
|
31 |
this latest JDK7 or OpenJDK7 build.

5. Check the sanity of doing a build with the current machine:
|
|
2
|
34 |
cd make && gnumake sanity
|
|
|
35 |
See README-builds.html if you run into problems.
|

37 |
6. Do a partial build of the jdk:
|
|
2
|
38 |
cd make && gnumake all
|
|
|
39 |
|
|
2658
|

7. Construct the images:
|
|
2
|
41 |
cd make && gnumake images
|
|
|
42 |
The resulting JDK image should be found in build/*/j2sdk-image
