27 # This file handles detection of the Boot JDK. The Boot JDK detection |
|
28 # process has been developed as a response to solve a complex real-world |
|
29 # problem. Initially, it was simple, but it has grown as platform after |
|
30 # platform, idiosyncracy after idiosyncracy has been supported. |
|
31 # |
|
32 # The basic idea is this: |
|
33 # 1) You need an acceptable *) JDK to use as a Boot JDK |
|
34 # 2) There are several ways to locate a JDK, that are mostly platform |
|
35 # dependent **) |
|
36 # 3) You can have multiple JDKs installed |
|
37 # 4) If possible, configure should try to dig out an acceptable JDK |
|
38 # automatically, without having to resort to command-line options |
|
39 # |
|
40 # *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with |
|
41 # javac) and not a JRE, etc. |
|
42 # |
|
43 # **) On Windows we typically use a well-known path. |
|
44 # On MacOSX we typically use the tool java_home. |
|
45 # On Linux we typically find javac in the $PATH, and then follow a |
|
46 # chain of symlinks that often ends up in a real JDK. |
|
47 # |
|
48 # This leads to the code where we check in different ways to locate a |
|
49 # JDK, and if one is found, check if it is acceptable. If not, we print |
|
50 # our reasons for rejecting it (useful when debugging non-working |
|
51 # configure situations) and continue checking the next one. |
