Debug 32 bit application with gdb in 64 bit environment

Question

Hi all; Is there any specific step required to debug 32 bit application with 64 bit gdb under 64 bit O.S.

Normally I use -m32 switch for gcc, is there something like for gdb?

Answer 1

No: 64-bit GDB can debug either 32 or 64-bit processes.

This message warning: the debug information found in "/lib/ld-2.11.1.so" does not match "/lib/ld-linux.so.2" (CRC mismatch) simply means that your installed libc-debuginfo package does not match your installed libc package, and that you will not be able to do source-level debugging on ld-linux.so.2. Most of the time you don't want to debug anything in ld-linux.so.2 anyway, so the message is harmless.
