Unable to compile MOOSE due to PETSc error in Linux

[sb50nemo]

I am trying to install MOOSE on my linux machine by following the procedure in MOOSE Framework - Getting started.. However, I am unable to compile MOOSE because of the following error:

/home/user/miniconda3/envs/moose/include/petscsys.h:211:6: error: #error "PETSc was configured with MPICH but now appears to be compiling using a non-MPICH mpi.h"
211 | # error "PETSc was configured with MPICH but now appears to be compiling using a non-MPICH mpi.h" | ^~~~~

How can I deal with this error? Any suggestions would be much appreciated. Thank you.

There appears to be multiple MPI wrappers available within your PATH, and make is choosing the wrong one.

Can you tell us more about the machine you are operating on? Linux? What Distro/Flavor? Also, a report of what your environment looks like would be very helpful (these sorts of issues are almost always environment related):

env

Do you use modules? Any loaded (env above would tell us)?

module list

What does your PATH look like (env above would tell us):

echo $PATH

Cheers!

Thanks Jason!

I figured out that I needed to install mpich module, and then I was able to install MOOSE.

Thanks a lot for your help!

Hi, I found multiple MPI wrappers are available in my PATH, how could I choose the correct one.

Thank you for your help!
