You can't build PETSc libraries with mpich1 and expect it to work with mpich2.
If there was a configure failure with mpich2 - then send us the relavent configure.log file. Configure should have found mpich2 - if it were installed in the default location. Perhaps there was some other issue here.. Also - if mpich1 works - I'll recommend sticking with it on windows. [unless there is a specific reason - requiring mpich2] Satish On Sat, 25 Nov 2006, Ben Tay wrote: > Hi, > > I tried to install the mpich2 package 1st and compile the Petsc.
