Missing f2kcli.o when compiling psml2psf converter

Summary:

I am unable to compile the psml2psf converter on the latest commit of the psml-support branch. The main Siesta executable compiles just fine, but when trying to compile the psml2psf converter it complains that there is no recipe for f2kcli.o.

Code version:

The latest version of the psml-support branch as of this day (08-11-2021 at 14:31).

From the SIESTA.version: 3.0-root-348-gfba23d9b

The Commit Hash: 8f912890

System information:

OS: CentOS 8

Compiler: gcc (GCC) 10.3.0

Libraries:

• OpenMPI 4.1.1
• OpenBLAS 0.3.15
• ScaLAPACK 2.1.0
• LibPSML 1.1.10
• XMLF90 1.5.4
• LibXC 4.3.4
• LibGridXC 0.9.6
• flook 0.8.1

For the arch.make see the attached file. arch.make

I compiled with enabled MPI support in the arch.make (although I don't think the converter is compiled with MPI support).

Compilation output:

When compiling the psml2psf converter I get the error: make: *** No rule to make target 'f2kcli.o', needed by 'm_getopts.o'. Stop.

Possible fixes

I did a little bit of research myself and I tracked down the problem to the rewriting of command line parsing in this commit: 06f1d572 . During this rewriting the f2kcli.F90 file was removed, but the psml2psf converter still expects it to be there and therefore no longer compiles. If I checkout a commit just before this change, e.g. https://gitlab.com/siesta-project/siesta/-/tree/fba23d9bada9f9dd6d702da84225b8ad9991c987/ , then I am able to compile the converter just fine. So I would expect that a fix would be to either (temporarily) bundle the f2kcli.F90 file with the converter or to also rewrite the argument parser for the converter to not use this f2kcli file.
