[mpich-discuss] cygwin & mingw64 & windows 7 (64bits)

[Jayesh Krishna]

Hi,
 It looks like mingw gcc doesn't play nice with windows libraries (Cygwin gcc - atleast the newer versions - works well with windows libs). I verified that creating an MPICH2 wrapper library works with C programs compiled with mingw.
 I am in the process of modifying MPICH2 to support gfortran (Currently we only support g77). Follow the ticket - https://trac.mcs.anl.gov/projects/mpich2/ticket/278#comment:9 - on this effort.
 I should be able to provide you a custom library that you can use in a day or two.
 
Regards,
Jayesh

for info :

I install TDM-GCC (64bits) and I have the sames symptomes but the gdb works in ssh/bash environement  :

gfortran -g -IC:\\mpich2\\include -c pi3f90.f90 -fno-range-check -fsecond-underscore
gfortran -g -o pi3f90 pi3f90.o -LC:\\mpich2\\lib -lfmpich2g  -lmpi
