Hi<div><br></div><div> 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.</div>
<div><br></div><div>Here are the steps that I have followed:</div><div>a) Downloaded the MPICH2 source code (1.2.1p1) from <a href="http://www.mcs.anl.gov/research/projects/mpich2/" target="_blank">http://www.mcs.anl.gov/research/projects/mpich2/</a> </div>
<div>b) Did the regular configure/make/make install steps in the cygwin environment in Windows. </div><div> ( set C compiler as gcc and Fortran compiler as gfortran)</div><div>c) Downloaded parallel netcdf (parallel-netcdf-1.2.0.tar.gz) <span style="font-family:Verdana, Arial, 'Bitstream Vera Sans', Helvetica, sans-serif;font-size:13px"><span style="background-color:initial;padding-left:16px;background-repeat:no-repeat no-repeat"> </span></span>from <a href="http://trac.mcs.anl.gov/projects/parallel-netcdf/wiki/Download" target="_blank">http://trac.mcs.anl.gov/projects/parallel-netcdf/wiki/Download</a></div>
<div>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)</div><div>
<br>
</div><div>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.</div><div><br></div><div>Thanks & Regards,</div>

Hi,<br>
As Rob mentioned the error might be due to the way netcdf checks for MPI-IO support.<br>
Can you give us details on how you configure netcdf with MPICH2 ?<br>
<br>
(PS: MPI-IO is available with MPICH2 on windows even if you use the installers for your installation.)<br>

Hi<br>
<br>
<br>
Initially, I had used the installers availabe at the MPICH 2 website and that was giving the error mentioned before. I then, downloaded<br>
the source code and built MPICH2 from that (configure/make/make install) in cygwin and linked this MPI while configuring parallel<br>
netcdf. Now, it is not giving that error and it moved ahead.<br>
<br>
<br>
Thanks & Regards,<br>

Hi,<br>
Did you build MPICH2 from source (configure/make/make install) under cygwin environment ? Or did you install MPICH2 using installers available at the MPICH2 website ?<br>
<br>

Hi<br>
<br>
<br>
Does MPICH2 on Microsoft Windows support MPI-IO ?<br>
<br>
<br>
I was checking on this site <a href="http://www.mcs.anl.gov/research/projects/romio/" target="_blank">http://www.mcs.anl.gov/research/projects/romio/</a> where it says that ROMIO is included as a part of MPICH 2.<br>
<br>
<br>
The reason I ask this is because I am trying to configure parallel netcdf library on Windows through the cygwin environment. While doing "configure" it stops with the following message:<br>
<br>
<br>
<br>
----------------<br>
<br>
<br>
checking MPI-IO support in MPI implementation... configure: error: mpi implementation does not support MPI-IO<br>
<br>
<br>
---------------<br>
<br>
<br>
The MPI implementation I used is MPICH2 which I was assuming supported MPI-IO on Windows as well. I tried using MSMPI but even that stopped with the same message. Any thoughts on this ?<br>
<br>
<br>
Thanks & Regards,<br>
Kunal<br>
