[mpich-discuss] query on MPICH2 on Windows

[Kunal Rao]

Hi

 I was able to configure and build the parallel netcdf library on Windows
using the cygwin environment and MPICH2 as the MPI implementation. I still
have to check if this library works with the application that I am trying to
link it to.

Here are the steps that I have followed:
a) Downloaded the MPICH2 source code (1.2.1p1) from
http://www.mcs.anl.gov/research/projects/mpich2/
b) Did the regular configure/make/make install steps in the cygwin
environment in Windows.
    ( set C compiler as gcc and Fortran compiler as gfortran)
c) Downloaded parallel netcdf (parallel-netcdf-1.2.0.tar.gz)  from
http://trac.mcs.anl.gov/projects/parallel-netcdf/wiki/Download
d) Again, did the regular configure/make/make install steps for parallel
netcdf in cygwin environment in Windows and used the previously built MPICH2
as the mpi implementation ( for the --with-mpi option)

The steps went fine and the libpnetcdf.a library has been built on Windows
through the cygwin environment. I will next check if this links properly and
works with the application.

Thanks & Regards,
Kunal
