  • We created a fpm.toml file in the root of the repository and succesffully built the applications and tests with fpm build
    • gfortran on ubuntu systems requires the -ffree-line-length-none flag, MacOS doesn't
  • We investigated how to pass compiler flags through the toml file.
    • the [project.<compiler>.<os>].flag field does not seem to work
    • @connoraird implemented a work-around in fpm and opened an issue and a PR
    • you can pass compiler flags through and environment variable or on the command line
  • Adding other fpm packages as dependencies is trivial. Adding non-fpm packages as dependencies is difficult
    • You can use metapackages.
    • Metapackages are hard-coded in fpm source code. There are about 5 of them.
  • We wrote a test suite with garden https://github.com/UCL-ARC/fortran-tooling/tree/4-add-garden-tests

I have created an issue to allow passing flags directly to the compiler.

I have raised a PR to fix the issue here.

I tried to write an fpm.toml for pFUnit, in order to pass it as a dependency. It's not clear how/where fpm tells the code how to be built, so I've experimented to see if it would "just" pick up the existing CMakeLists.txt in pFUnit. With a minimal fpm.toml, it's trying to build something and fails miserably, because it needs to pick specific sources to compile - done in cmake but not obvious how to do it in fpm yet. Tried to make it build with cmake using

[library]
source-dir = "src/funit"
build-script = "cd build && cmake .. && make"

but it looks like it fails before even getting to the point of calling the build-script. There's value in pursuing this a bit more, there might be a way...
