[petsc-users] Petsc not work in Windows-10

[Qin Lu]

 Hi Satish,
The ex2.exe works with "mpiexec -np 2" when I ran it from command line. Then I ran "which mpiexec", it actually points to Intel-MPI instead of MPICH2, probably because I have set the former's path in environment variable PATH in Win-10. I will try to reinstall Intel-MPI and build Petsc with Intel-MPI.
As for the crash of calling to KSPSetPCSide(ksp_solver,PC_RIGHT,ierr) in my Fortran-90 program, do you have any idea what can be wrong? Can it be related to MPI?
I tested config/examples/arch-ci-mswin-intel.py as you suggested, but got the following output:
============python ./arch-ci-mswin-intel.pyTraceback (most recent call last):  File "./arch-ci-mswin-intel.py", line 10, in <module>    import configureImportError: No module named configure============
Thanks,Qin


I will try to use Intel-MPI and see what will happen.
Thanks,Qin

So PETSc  is correctly built as static.

So its not clear which shared library this error is referring to. But then - this error was with petsc-3.4.2

You can always try to run the code manually without mpiexec - and see if that works.

cd src/ksp/ksp/examples/tutorials
make ex2
./ex2

Wrt MSMPI - yes its free to download

And PETSc does work with Intel-MPI. It might be a separate download/install. [so I can't say if what you have is the correct install of IntelMPI or not]

Check the builds we use for testing - for ex: config/examples/arch-ci-mswin-*.py

The configuration/compilation/installation seem to finish without problem, but test program (ex19) failed since it could not find a shared lib. Then I linked the libpetsc.lib with my program (in Fortran-90), but it got run time crash when it calls KSPSetPCSide(ksp_solver,PC_RIGHT,ierr) or other Petsc subroutines. Note that this package was built, tested and worked well with the same Fortran-90 program in my Windows-7 workstation.
