A More FHS-Compliant JDK Install

[Shea Levy]

Hi all, 

I've just successfully built openjdk6, and am wondering about
the best way to install it on my system, given that the /opt prefix is no
longer obviously appropriate for the build. I have an install that works
for now, but there are aspects I'm unhappy with. I am on a Linux From
Scratch system, so I install everything into /usr
(http://www.linuxfromscratch.org/blfs/view/svn/introduction/position.html
[1]), but everything that follows should apply to /usr/local. 

My set up
for now: 

I've copied build/linux-i586/bin/* to /usr/bin. No problems
there. 

I've copied build/linux-i586/lib/* to /usr/lib, but upon review I
think it probably belongs in a separate /usr/lib/java/ since there aren't
any .so files in the base of build/linux-1586/lib. If I try that, running
/usr/bin/java complains of being unable to find libjli.so 

I've copied
build/linux-i586/classes/ to /usr. This is the most disconcerting, as I'd
rather not add to the root of /usr and these files seem perfectly suited to
fit in /usr/lib/java. If I try moving it there, running /usr/bin/java
complains of having no class definition for Object. 

I've copied
build/linux-i586/j2sdk-image/man/man1/* to /usr/share/man/man1. No problems
there, though it would be nice if there were a share directory in
build/linux-i586/ 

I've copied build/linux-i586/include/* to
/usr/include/java. No problems there. 

I've copied build/linux-i586/docs/*
to /usr/share/doc/openjdk-6-20b 

Output of ldd /usr/bin/java:


linux-gate.so.1 => (0xb77b6000)
 libpthread.so.0 => /lib/libpthread.so.0
(0xb7793000)
 libjli.so => /usr/bin/../lib/i386/jli/libjli.so (0xb778a000)

libdl.so.2 => /lib/libdl.so.2 (0xb7786000)
 libc.so.6 => /lib/libc.so.6
(0xb7626000)
 /lib/ld-linux.so.2 (0xb77b7000)


System.getProperty("sun.boot.class.path"):


/usr/lib/resources.jar:/usr/lib/rt.jar:/usr/lib/sunrsasign.jar:/usr/lib/jsse.jar:/usr/lib/jce.jar:/usr/lib/charsets.jar:/usr/classes


1. Am I missing any important files if that's all I bring over from
build/linux-i586/ ? 

2. Am I right that some of these file locations
aren't the most appropriate given Linux standards? 

3. For
build/linux-i586/lib: I could manually relink all of the relevant binaries
to the new library locations. Would there be any problems aside from
linking in moving those files to /usr/lib/java? Is there a better way than
manual relinking to specify that those files lie in a different directory
(e.g. some sort of ALT env variable, or a simple modification to a
Makefile?) 

3. For build/linux-i586/classes: I could globally alias java
to java -Xbootclasspath:whatever, but that's ugly. I'm pretty sure there
has to be some Makefile I could edit to change the built in bootclasspath,
since build/linux-i586/j2sdk-image/bin/java looks in ../jre/classes, but
I'm not sure where to start looking. What Makefile would I need to modify?
Or is there an env variable I could set? 

4. In general, are there plans
to autotool the build or add an install target to the main Makefile?


Cheers,
