[mpich-discuss] Compatibility of MPICH with gfortran under windows

[Jayesh Krishna]

Hi,
 Looks like you are not providing the include/lib paths to the compiler/linker.
 You should be providing the include (-IC:\Progra~1\MPICH2\include) and lib (-LC:\Progra~1\MPICH2\lib) paths and link with the fortran MPI library (fmpich2). I would recommend checking the gfortran manual for more information.

Regards,
Jayesh

Hi, 

Thank you for your quick reply. 

I have tried to compile fpi.f with gfortran first and I get the following error message : 
C:\opentelemac\mpi\examples>gfortran fpi.f 
fpi.f:25: Error: Can't open included file 'mpif.h' 

I have tried a second time moving mpif.h to examples (without making any change in fpi.f) but it's not working with the following message : 
C:\opentelemac\mpi\examples>gfortran fpi.f 
C:\DOCUME~1\ALEXIS~1.BE~\LOCALS~1\Temp\ccf23b32.o:fpi.f:(.text+0x11): undefined

I have no g77 compiler command. 

I've the same error when I try to compile with g95. 

Regards,

Hi,
 Are you able to compile with g77 ?
 I would recommend that you first try compiling a simple MPI program (c:\Program Files\MPICH2\examples\fpi.f) before proceeding with building the software package.

Jayesh

Hi, 

I'm new user of MPICH2 that I need in order to compile a parallel version of Telemac modeling system. 
I have an issue when compiling the source code of Telemac under windows xp 32 bits with gfortran. 

I have tried to compile with the binary distribution of MPICH2 for windows but the library doesn't seem to be compatible with gfortran. I would like to know if I can build MPICH2 from the sources with a fortran compiler (but no intel fortran - it may be gfortran or g95) ? 

Any help will be appreciated, 

Thanks in advance,
