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

[Satish Balay]

MPICH is unsupported - and we haven't tested with it for a long time.

And petsc-3.4.2 is from 2013 - and untested with current gen os/compilers/libraries.

Can you send logs from Petsc-3.12.4 build [or try latest Petsc-3.13.0]?

We recommend 64bit MSMPI for windows.

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.
