[mpich-discuss] MPICH2 Win 7 installation

[Jayesh Krishna]

Hi,
 You should explicitly specify the include and lib directories when you compile your code with gcc (There is no equivalent to mpicc with MPICH2 on Windows. mpicc is a script that captures the paths_to_compiler+libs+flags etc) on Windows.

(PS: "gcc -I.... -L.... -o mpi.exe mpi.c -lmpi")

Regards,
Jayesh

Hi Jayesh, 

Thanks for your reply. 

I DID use "Run as Administrator". When I use the command "msiexec /I mpich2-1.4.1p1-win-x86-64.msi" a series of windows come up. They are shown in attached file MPICH2_Install.pdf. As you can see, at no time there is a configuration setting option and installation is succesful. Then, when I run the MPICH2 examples they do fine, see attached MPICH2_Example.pdf . I do not see any configuartion settings. Am I missing something here?? 

The problem is when I use gcc. When I run my own Helloworld_MPI.c example, see attached Helloworld_MPI.pdf, it cannot find mpi.h (it's in the PATH and have no way to include it in gcc as far as I know) . I have run my code in Unix using "mpicc" and it runs just fine. Any suggestions?? What compiler do you use to be able to include mpi.h?? 

Kind regards. 

Alejandro

Hi, 
Please uninstall MPICH2 and re-install it following the instructions in Section 9.4 (NOT 9.1) of the MPICH2 installer's guide ( http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs ).
