Bug 80860 – gcj missing from path

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Paul Slinski 2005-02-05 06:25:48 UTC]

I was attempting to merge "pdftk" which uses gcc's gcj compiler, however, it cannot find gcj even though the gcj flag was on when I compiled gcc and the binary exists in /usr/i686-pc-linux-gnu/gcc-bin/3.4.3/

Is this simply missing from the path, or is it not available for a reason?

Reproducible: Always
Steps to Reproduce:
1. merge gcc with gcj flag enabled
2. attempt to merge pdftk
3. fail

Actual Results:  
sisyphus # emerge pdftk
Calculating dependencies ...done!
>>> emerge (1 of 1) app-text/pdftk-1.12 to /
>>> md5 src_uri ;-) pdftk-1.12.tar.gz
 * It seems that your system doesn't provides a Java compiler.
 * Re-emerge sys-devel/gcc with "java" and "gcj" enabled.

!!! ERROR: app-text/pdftk-1.12 failed.
!!! Function pkg_setup, Line 20, Exitcode 0
!!! gcj not found.
!!! If you need support, post the topmost build error, NOT this status message.


Expected Results:  
Successful compile of pdftk.

[Comment 1 Jan Brinkmann (RETIRED) 2005-02-05 06:35:26 UTC]

you have to merge gcc with the useflags 'java' and 'gcj' enabled.

[Comment 2 Paul Slinski 2005-02-05 08:30:41 UTC]

Please see use flags. Both were enabled.

[Comment 3 Paul Slinski 2005-02-05 08:31:07 UTC]

This is not resolved.

[Comment 4 Jan Brinkmann (RETIRED) 2005-02-05 08:36:12 UTC]

maybe 'source /etc/profile' not done? if you emerged gcc in the running shell that could be the problem

[Comment 5 Paul Slinski 2005-02-05 09:02:16 UTC]

Sorry Jan, no. I have rebooted since the rebuild.

Either the pdftk build is no good or the gcc build failed to place gcj in my path.

[Comment 6 Paul Slinski 2005-02-06 16:38:56 UTC]

OK, it would appear that gcc-config (gcc-config-1.3.10-r1) either wasn't working properly and I was still using gcc-3.3.4 profile.

Running gcc-config 3.4.3 fixes the problem.

[Comment 7 Mamoru KOMACHI (RETIRED) 2005-02-12 06:44:10 UTC]

All right, I asume it's not a problem in the ebuild.

[Comment 8 mykhal 2006-03-21 14:30:59 UTC]

Maybe following helps even though I'm dealing with gcc-3.4.5 ..
I have had the same problem (gcj not found). I created the symlinks, which gcc
ebuild has forgotten to create:

/usr/bin directory:

gcj -> gcj-3.4.5
gcjh -> gcjh-3.4.5

(change 3.4.5 to your gcc version)

..and then, the pdftk compilation started succesfully. Unfortunately, it failed later, but it's probably another problem.

[Comment 9 Ian Guerit 2008-08-18 10:09:37 UTC]

If the gcc symlinks weren't created automatically it is probably with good reason (hence why you may end of with build failure later) - make sure the selected profile is the one with the gcj use flag enabled

Check `gcc-config -l` and that the selected profile is the one you enabled the gcj use flag on, if not either switch profiles or re-emerge the profile you want to use
