[mpich-discuss] How to modify CFLAGS

[zhouxu(NUDT)]

Hi,
   I notice that the CFLAGS in all Makefiles of mpich2 is already set to
" -O2 $(MPICH2_MAKE_CFLAGS)". I want to know if I can change the CFLAGS in
specified Makefile. For example, I want to compile source files in "pt2pt"
with additional "-g" option. How should I modify the corresponding
Makefile.sm.

Thanks.
