I'm trying to debug a shared library loaded and can't seem to get gdb to see the library symbols. This is on an Intel based machine running RedHat 6.1 with a custom kernel. The app is glxsimple which links against libGL.so. This library dlopen's i81xgicd.so which in turn dlopen's i810gdev.so. After libGL.so dlopen's i81xgicd.so, I can set break points in i81xgicd.so, but I can't set break points in i810gdev.so after it is dlopen'ed. If I run "gdb glxsimple" and wait for it to seg fault. "info shared" lists (gdb) info shared >From To Syms Read Shared Object Library 0x40013000 0x4006808c Yes /home/ctuffli/XF4/lib/libGL.so.1 0x4006a000 0x4012ce1c Yes /home/ctuffli/XF4/lib/libX11.so.6 0x40131000 0x402238dc Yes /lib/libc.so.6 0x40224000 0x40234e44 Yes /lib/libpthread.so.0 0x40235000 0x4024197c Yes /home/ctuffli/XF4/lib/libXext.so.6 0x40242000 0x40244d0c Yes /lib/libdl.so.2 0x40000000 0x400126b0 Yes /lib/ld-linux.so.2 0x40246000 0x4048ae08 Yes /home/ctuffli/i81xgicd.so 0x00000000 0x404a6fd8 Yes /lib/libm.so.6 but not i810gdev.so If I let glxsimple segfault outside of gdb and run "gdb glxsimple core", "info shared" lists (gdb) info shared >From To Syms Read Shared Object Library ... 0x404a7000 0x40502d30 Yes /home/ctuffli/XF4/lib/i810gdev.so Any idea what is wrong or what else I should try?
