[petsc-users] Installation question

[Pham Pham]

I reconfigured PETSs with installed MPI, however, I got serous error:

**************************ERROR*************************************
  Error during compile, check arch-linux-cxx-opt/lib/petsc/conf/make.log
  Send it and arch-linux-cxx-opt/lib/petsc/conf/configure.log to
petsc-maint at mcs.anl.gov
********************************************************************

Please explain what is happening?

Thank you very much.
