gdb can not find debug info on Centos

Question

I am trying to figure out a very strange issue. I have CentOS 6.5 system with gdb:

GNU gdb (GDB) Red Hat Enterprise Linux (7.2-75.el6)

Answer 1

Your GDB is pretty old. Your GCC is fairly new.

I suspect that your GCC is emitting DWARF4 debug info (default as of gcc-4.8 according to release notes), which your GDB does not recognize.

Do you get better result with -gdwarf-2 instead of -g?

If so, upgrade your GDB or use -gdwarf-2 with this compiler.
