[petsc-users] PETSc Windows Installation

[Satish Balay]

Make sure you have cygwin openmpi installed [and cywin blas/lapack]

$ cygcheck -cd |grep openmpi
libopenmpi-devel              4.1.2-1
libopenmpi40                  4.1.2-1
libopenmpifh40                4.1.2-1
libopenmpiusef08_40           4.1.2-1
libopenmpiusetkr40            4.1.2-1
openmpi                       4.1.2-1
$ cygcheck -cd |grep lapack
liblapack-devel               3.10.1-1
liblapack0                    3.10.1-1


> ./configure --with-cc=gcc --with-cxx=0 --with-fc=0 --download-f2cblaslapack

Should be:

> > $ ./configure --download-scalapack --download-mumps

i.e [default] --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90 [an default cygwin blas/lapack]
