Are you looking at sequential use of PETSc - or parallel? I see mpich doesn't work with msys/mingw. You can try an install of petsc with msys - and see if it works. If not send us logs at petsc-maint. [its possible things won't work - and you would have to use cygwin/gfortran. Presumably it shouldn't conflict with your msys install] Satish
