Building on Windows

Building GridPACK on Windows is not for the faint of heart.

System Preparation

The following are available as native Windows applications and can just be installed in the normal Windows way:

• Visual C++ in some form.
  • The "free" ones, Visual Studio Express and Community, should work.
• Windows SDK
  Usually, this is just installed with Visual Studio
• CMake is required
• A minimal Cygwin installation is necessary.
  Cygwin is required to build, and test for, PETSc. If the system has a Cygwin installation that is being used, it would probably be best to make another installation for GridPACK installation exclusively.
  • Minimum required packages:
    • Base
    • Python
  • Rename /usr/bin/link.exe so it does not interfere with Windows LINK.EXE
  • If you want to use a Cygwin shell to build and/or debug GridPACK applications:
    • Do not install a compiler set.
    • Do not install CMake.
• Microsoft MPI
  This appears to be the only modern implementation available for Windows. In the past, the OpenMPI and MPICH implementation were available for Windows, but no more.
• (optional) MS-MPI Debugger Extension is useful for debugging problem with parallel programs.
• Choose a place to install libraries. C:\GridPACK is used in this case.

Build Required Libraries

BLAS/LAPACK (CLAPACK)

Some implementation of BLAS/LAPACK is required for PETSc and some other libraries. The implementation described here was chosen because it does not require a Fortran compiler. It is apparently really slow. It will probably be necessary to install Intel compilers and MKL in order to get improvement in speed. The Windows port of CLAPACK is described here.

• Configure, build, and install

   set prefix="C:\GridPACK"
   cmake -Wdev ^
       -G "Visual Studio 10 2010 Win64" ^
       -D CMAKE_INSTALL_PREFIX:PATH="%prefix%" ^
       ..
   cmake --build . --config Release
   cmake --build . --target install --config Release
