Petsc can also be used from gnu compilers. You need to specify the correct compilers you wish to use to PETSc configure I presume you would like to use PETSc from fortran [using intel fortran] on windows? If so: - install cygwin [for build tools per installation instructons] - install MLK for blas/lapack [if available or use configure option --download-f-blas-lapack=1] - install MPICH for windows [or if you wish to use PETSc sequentially, use --with-mpi=0] Now counfigure PETSc with the required compilers [check config/cygwin-ms.py] ./config/configure.py --with-cc='win32fe cl' --with-fc='win32fe ifort' [autodetect mpich & mlk from default locations] BTW: We test with compaq fortran - and haven't tested with intel fortran on windows for a while. If you encounter problems - let us know. Satish On Tue, 28 Mar 2006, Girish Pillai wrote:

Hi Satish,

Somehow I thought it was the Gnu compilers that were being used for the Windows port done with the help of cygwin. So I think I was wrong in making that assumption.

So what I really want is to build it with the MS-VisualC++ compiler and Intel Fortran Compiler. So cygwin is just used for the build purpose and the GNU compilers never get used. Is that correct?

Thanks much, Regards, Girish

yes - PETSc can be installed with MS-C/Compaq-Fortran [or intel compilers] on windows.

However the build system still requires cygwin to build the PETSc libraries.

Check the installation instructions for additional info. If you encounter problems - send us the erros with appropriate logfiles to [email protected]

[If configure doesn't work - send us configure.log]

Folks,

Is there a port of PETSc library on Windows platform. I am looking for native Windows port, not the cygwin port.

Can one of you please respond?

The config script does not work properly for Windows when I tried to run it.

Thanks, Girish
