I'm new to debugging using core dumps. I've managed to get core dumps + symbols using g++ and gdb under linux. I compile using g++ -g -dH, and i debug using gdb executableFile -c coredumpFile.
This is a test program backtrace in the original computer (a gentoo box), where the program was compiled, run, and coredumped: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x4017a101 in raise () from /lib/libc.so.6 #2 0x4017b8e8 in abort () from /lib/libc.so.6 #3 0x400ed794 in __gnu_cxx::__verbose_terminate_handler () from / usr/ lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 #4 0x400eb1b5 in ?? () from /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/ libstdc++.so.6 #5 0x400eb1f2 in std::terminate () from /usr/lib/gcc/i686-pc-linux- gnu/4.1.2/libstdc++.so.6 #6 0x400eb2aa in __cxa_rethrow () from /usr/lib/gcc/i686-pc-linux- gnu/ 4.1.2/libstdc++.so.6 #7 0x08049047 in main () at main.cpp:46 And this is what i get after i scp the exe and dump to a different computer (a kubuntu box): (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x4017a101 in modff () from /lib/libc.so.6 #2 0x4017b8e8 in sigorset () from /lib/libc.so.6 #3 0x400ed794 in ?? () #4 0x0804c038 in ?? () #5 0x00000001 in ?? () #6 0x00000002 in ?? () #7 0x4027d560 in ?? () from /lib/libc.so.6 #8 0x40035000 in ?? () #9 0x00000001 in ?? () #10 0x0804c060 in ?? () #11 0x4000d6e9 in ?? () from /lib/ld-linux.so.2 #12 0x400351b8 in ?? () #13 0x40035c10 in ?? () #14 0x00000000 in ?? () As you can see, the backtraces differ, and i lose almost all symbols. What am i doing wrong? Thanks in advance! _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
