GDB 7.2 problem #163

Closed dinsh opened this issue almost 13 years ago

Hi, I use GDB 7.2 to debug linux-2.6.39 by Jonas. I use command "file vmlinux", but I cannot see any source when I use command "list". There are just two files: libgcc2.c & libgcc2.h. The example in opencore website (demo_or32_sw) is OK. Could you help me ?? Thx a lot!

Hi dinsh Did you build vmlinux with all its symbols included. By default Linux builds without symbol information (makes a much smaller file). In any case be careful when debugging vmlinux. If you are simulating with Or1ksim, the RSP server does not get address translation right. It is really debugging physical addresses, which will not match up with your symbol table. I don't think this is a bug. See if my suggestions help, and if all is OK, I will close the bug. HTH Jeremy

Thank Jeremy. Could you give me some instructions how to build vmlinux with all its symbols included. I try to change some options about GCC. But it cannt work. Thx a lot!
