I'm running on a HP pavilion laptop, with slackware 12.2. I'm also wondering if this might have something to do with an earlier bug I reported: GCC Bugzilla Bug 41472
The gjar you have installed is broken.
Shouldn't gjar be built (and used) by the bootstrap build? It seems that it was: find -name gjar -ls 4108357 4 -rwxr-xr-x 1 ronis ronis 2048 Oct 20 02:27 ./i686-pc-linux-gnu/libjava/classpath/tools/gjar There is a system installed one from my last gcc build. So, if this is broken, there's still a problem.
gjar is broken. *** This bug has been marked as a duplicate of 39177 ***
