[petsc-dev] Fwd: [petsc-maint] Petsc configure Error on Edison on NERSC

[Barry Smith]

   Satish,

     We get too many mails like this, it wastes our time and their time. In config/configure.py please add checks if the machine is a cray 
that the user did not provide an MPI dir, and that the user did pass in 

  '--with-clib-autodetect=0',
  '--with-cxxlib-autodetect=0',
  '--with-fortranlib-autodetect=0',

and any other mandatory things and error out with a very useful error message telling them what options to use and not to use.

  Barry

It is absurd to think that somehow Cray users will magically know to use the auto detect = 0 flag and not provide an MPI dir etc.
