Here is my .gdbinit: set auto-solib-add 1 set solib-absolute-prefix /opt/crosstool/powerpc-linux/gcc-3.4.1-glibc-2.3.3/powerpc-linux target remote 10.128.128.251:9000 set confirm off sym ./test -readnow handle SIG32 nostop noprint break main shared cont shared info sharedlibrary Problem is that I can't see the threads while debugging, but only the main thread. When I try to put a breakpoint to put thread function I then have: Program received signal SIGTRAP, Trace/breakpoint trap. Also, I always have: No shared libraries loaded at this time. If I debug the same program compiled for x86 on the PC, I can see all the shared libraries that gdb has loaded. For some reason, that's failing with gdbserver. When I run gdb with strace, I don't see that gdb try to load libthread_db.so, as I think it should. I have tried with versions 5.3, 6,2 and 6.3 of gdb/gdbserver. Any idea what is wrong ? Thanks in advance, Olivier
