Hi Pierre, I'm using 3.12.2, which is a bit old, but needed for the Pflotran version I'm using. It certainly predates that merge. Many thanks for pointing me to that merge - if nothing else I could now study that and try manually implementing it to see if it helps my situation. Thanks, Daniel On Tue, May 11, 2021 at 10:28 AM Pierre Jolivet <[email protected]> wrote:
Hello Daniel, Which PETSc version are you using? I think this has been addressed there: https://gitlab.com/petsc/petsc/-/merge_requests/3671
Thanks, Pierre

Hello,
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
