the flags in package.py are usually for --download-package. I don't know if we add such flags to petsc build here. configure is a bit convoluted - so I can't say exactly where this would go. Also we have to add them in such a way the user specified FFLAGS override default FFLAGS configure detects. So likely some hack [from MPI side] in config/BuildSystem/config/compilerOptions.py > Is this tested on some Cygwin box (MS-MPI 10.1.2 + gfortran 10)? > I see arch-ci-mswin-intel.py is using MS-MPI (which version?) but with ifort. I don't know if one can use native libraries from cygwin/gcc gfortran. So we don't support this. Primary windows builds builds are for native compilers - i.e MS, Intel [using cygwin build tools] - and they can use MS-MPI and IntelMPI Satish
