Hi, I’m having troubles with gcj for a while now, and can’t find it. It’s not http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42409 : -rw-r--r-- 1 root root 10171111 Apr 4 07:37 /usr/share/java/libgcj-4.6.jar Nor is it http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45773 as the code from comment #16 (when compiled to .class on another system) works as it should.
How to reproduce? Boot up Debian/m68k, e.g. in a VM: https://wiki.debian.org/Aranym/Quick Run apt-get update if needed, then apt-get install gcj-4.{4,6}-jdk root@aranym:~ # cat >x.java class x { } root@aranym:~ # gcj-4.6 -c x.java -v -save-temps Using built-in specs.

I’ve tried running it with strace (which in itself is a PITA on m68k as it’s slow as hell due to the TLS emulation used) but was unable to spot anything pointing to it looking in wrong places. If someone has an idea how to debug this, you’re welcome. gcj-4.7 FTBFS’d the last time I tried to build it, but as of writing this I’ve started to try to compile its latest version, since there have been uploads in the meantime, maybe it got fixed… but maybe it would have the same problem… anyway, the compile’s going to take 3 (yes, three) days, so, in the meantime, please look at this.
