I have the following error:

PETSc Error --- Open MPI library version
FUJITSU MPI Library 4.0.0 (4.0.1fj4.0.0) does not match what PETSc was compiled with 4.0, aborting

I have to configure and compile petsc in a cross compilation environment and run it 

in a different one. I'm trying to run src/snes/examples/tutorials/ex19 to confirm things 

are working.

It looks like this error could be down to some confusion with string comparison

("4.0.0" =/= "4.0"), or it could be some nightmare misalignment between the two 

environments I have to use, and/or my efforts to configure PETSc. I'm trying to 

determine which.

Is there some way to turn off this version checking, to see if it is just a string comparison

error and maybe the rest of the program will run fine? Or could someone point me to where

in the source code/configuration scripts these numbers are harvested and this error is generated, so I can try to get a better idea about what is going on?

Thanks,

Daniel Stone
