Compilation issues，I built the environment under WSL2 ubutun20.04 on Windows

[q1165600785]

When I run the first step command, an error occurs. Why is this? Is there any error in the installation of openmpi or mpich?

Can you attach the output of config.log? Possibly in ac/deps/fms/build/config.log but it will depend on what exactly you were trying to build.

We have tested in WSL, but no one on the development side uses it regularly.

(There was an error in this post, the path has been updated to ac/deps/fms/build/config.log)

Not sure if this was ever sorted out, but often a failure to find gettid is just a symptom of a bigger problem with compiler setup.

The problem seems to be with the MPI compiler setup. Currently it does not ensure that FC and MPIFC are the same compiler. This is not usually a problem on personal system, but HPC systems can cause issues here.

Explicitly setting MPICC=$(CC) and MPIFC=$(FC) (or to your actual values of CC and FC can sometimes solve this problem.
