[gentoo-java] eclipse on ppc

[gentoo-java] eclipse on ppc

[David Gurvich]

I have used the ebuild from the java-experimental overlay,
eclipse-sdk-3.2_rc2.  Aside from having to modify the java5home variable
manually it compiled cleanly.

My problem concerns ibm-jdk-bin.  On ppc systems the only real option is
ibm-jdk-bin.  If I start eclipse with either 1.4.2 or 1.5.0 as the system jvm
eclipse will crash soon after attempting to access the menus.  If I use the
following script
-----------------------------------------------------------------------------
#!/bin/sh

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/kde/3.5/lib
export LD_LIBRARY_PATH

/usr/bin/java-config -s 1
/usr/bin/eclipse-3.2 -vmargs -Xmx256M
/usr/bin/java-config -s 2
---------------------------------------------------------------------------
Eclipse opens and runs with no problems.
The only part which makes a difference is the java-config -s 1, which sets
 the system jvm to gcj-4.1.0.  Do you know what the problem or solution may
 be?

Please try to catch the exact error and logs if possible.

Any particular reason why you'd need to add the kde lib to 
LD_LIBRARY_PATH? I would think it would already be there.

You might want to use the name of the vm, instead of a number, just in 
case the number changes.

The ebuild set java5home to /opt/ibm-jdk-bin-1.5, I just changed it to 
ibm-jdk-bin-1.5.0..
local java5home=/opt/ibm-jdk-bin-1.5.0

I was trying out some Qt code in eclipse and it wouldn't run without that.  It 
is in fact in /etc/ld.so.conf, but eclipse wanted an explicit LD_LIBRARY_PATH 
set prior to starting eclipse.  I couldn't figure out how to configure that 
from within eclipse so put it in the startup script.

Do you mean code such as the following:
eclipse-3.2 -vm "/opt/ibm-jdk-bin-1.4.2.04/bin/javaw"
If so, I have done that for both ibm jdks, and it crashed with both.

No, he meant to replace "java-config -s 1" with "java-config -s gcj-4.1"
(or whatever is listed for this vm in brackets if you do java-config
-L). Also you said system jvm, -s is for user jvm.

What does 'GENTOO_VM=ibm-jdk-bin-1.5 java-config-2 --jdk-home' tell you?

Also, could you try with the most recent version, 3.2_rc3 ?

That can't be good. Is there anyone else with PPC hardware that can
test/verify this?

That gives the proper result of "/opt/ibm-jdk-bin-1.5.0"

I will test it Saturday.

I'm getting some oddball syntax error somewhere in the ebuild.  Can't figure 
out what it is.  Claims not to like the inherit line.

I seem to have 2 versions of 3.2_rc3 on my system.  First in java-experimental 
second in gcj-overlay.  The one in java-experimental is the one with syntax 
error.

I've compiled 3.2_rc3-r1 and it crashes using ibm-jdk-bin.  Using gcj it does 
not, but gets caught in some loop.  I seem to recall using -compilelibs for 
3.2_rc2.  Perhaps that had something to do with it.

eclipse-sdk-3.2_rc3-r1 compiles cleanly as does rc2, but still crashes when 
used on ppc with ibm-jdk-bin as the jvm for eclipse.  There is no problem 
actually using ibm-jdk within eclipse for projects..

I have been using gcj as the jvm for eclipse.  ibm-jdk acquires between 20M 
and 50M upon startup, while gcj uses 100M+, currently using 123M.  Perhaps it 
is a memory problem.  Though I have tried  to start ecllpse with more memory 
the ibm jdk does not seem to accept it.

When I first compiled rc3 I did not modify with -compilelibs and it seemed 
quite slow, but the second time I did, now eclipse seems relatively speedy 
after startup.
