I installed the oneAPI C++ and fortran compiler on WSL2 and tried to compile a program that has both fortran and C++ routines. I get an error message during installation that it could not find g++.

However g++ is installed by default, i.e.

wbwright@GRLWL0224100067:~/glennice/glennice-home$ which g++
/usr/bin/g++
wbwright@GRLWL0224100067:~/glennice/glennice-home$ g++ --version
g++ (GCC) 12.4.1 20241226

I can compile some programs, except when I try to use mpi

Again, mpich 4.0.3 comes with the distribution.

Hi, could you give some more details about the error you saw ?

It seems like you're trying to compile a mpi code, could you post the command and maybe also a sample code that can be used to demo the issue ?
