Ubuntu Fortran CoArray: f951: Warning: Nonexistent include directory ‘/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran-mod-15/openmpi’

System:

Ubuntu 22.04.1 LTS (Jammy Jellyfish) 64-bit
Kernel Linux 5.15.0-46-generic x86_64
MATE 1.26.0

Installed packages:

gfortran --> gfortran-11
libgfortran-11-dev
libcaf-mpich-3
libcaf-openmpi-3
libcoarrays-dev
libcoarrays-mpich-dev
libcoarrays-openmpi-dev

Trying to compile a CoArrayFortran program via caf caf01.f90 results in the error

f951: Warning: Nonexistent include directory ‘/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran-mod-15/openmpi’ [-Wmissing-include-dirs]

failed to compile.

There is a directory /usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran-mod-15/mpich/, maybe this can be used instead, but how to tell the compiler?

Edit1:

$ LANG="C" caf caf01.f90

failed to compile.

The compile-command is caf: /usr/bin/caf -> /etc/alternatives/caf -> /usr/bin/caf.openmpi -> /etc/alternatives/caf-openmpi -> /usr/lib/x86_64-linux-gnu/open-coarrays/openmpi/bin/caf. In this last file there are the lines

# Always make extensions module available, user can choose whether to `use` it or not
caf_pre_flags=("${mod_dir_flag}/usr/lib/x86_64-linux-gnu/fortran/")

but no line including gfortran-mod-15.

Edit2:

I made a (symbolic) link

/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran-mod-15/openmpi/

->

/usr/lib/x86_64-linux-gnu/openmpi/lib/../../fortran/gfortran-mod-15/mpich/.

The warning about the nonexistent include directory is gone, but the other errors remain:

LANG="C" caf caf01.f90

Summing up "Using CoArrays with gfortran at Ubuntu 22.04" worked for me like this:

Installing the packages:

sudo apt-get install gfortran libcoarrays-dev libcoarrays-openmpi-dev libcaf-openmpi-3

Compiling:

gfortran -fcoarray=lib coarray-fortran-program.f90 -lcaf_openmpi

Running:

cafrun -n 3 a.out

(-n 3 = Number of Images) or with option

cafrun -n 3 --oversubscribe a.out

(if there is an error without this option). cafrun might be replaced with mpirun or mpiexec.
