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

Hello Daniel,
Which PETSc version are you using?
I think this has been addressed there: https://gitlab.com/petsc/petsc/-/merge_requests/3671

Thanks,

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
