[mpich-discuss] Cannot compile with debugging symbols

Tue Aug 30 11:21:45 CDT 2011

I recommend dropping the "--enable-debuginfo" option and adding the "--enable-g=dbg" option instead.  If you don't specifically know that you need the special debugging functionality then you don't need it.

Your configure options are asking for the additional MPI message queue debugging.  If you simply need to be able to see debugging symbols in your debugger then you can configure instead with "--enable-g=dbg" or "CFLAGS=-g".
