[petsc-users] Compiling with Intel MPI options

[Barry Smith]

  Steven,

   We are linking against a non-existant library as a test of the linker, the linker is returning without an error code. This means that we cannot trust the error codes returned from the linker which means that our configure tests will not work. 
  
    First thing to do is check if you have any later versions of Intel MPI compilers installed on your systems or if there are any updates to the compilers. Check with your systems support if you don't install the compilers etc yourself.
