Compiling fpm with GCC 5

[awvwgk]

Anyone has experience building fpm with GCC 5 / MinGW on Windows? I know TOML Fortran is GCC 5 compatible, not sure about fpm itself though. Being able to compile with GCC 5 would enable us to ship Windows binaries on conda-forge.

GCC 5 dates from 2015 - about half an eternity in software terms. There is a version of MinGW which has GCC 10.2.0 - I must admit that my understanding of the distributions of MinGW is limited, but an up-to-date installation should have at the very least have access to that version.

Sadly, GCC 5 / MinGW is still the tool chain available on conda-forge for Windows, the alternative is flang 11, which is broken for sure with TOML Fortran. Maybe conda-forge is not the best way to distribute fpm for Windows, but I didn't get much feedback on Windows distributions when I asked on the discourse recently (https://fortran-lang.discourse.group/t/distributing-fortran-projects-for-proprietary-oses/760).

Hm, I saw the title but misunderstood it apparently - I did not associate "proprietary" with "Windows" or "MinGW" or the like. I do not know much about conda-forge, but there ought to be alternatives ... (Or should I say: there should?) Op di 16 mrt. 2021 om 11:10 schreef Sebastian Ehlert < ***@***.***>:

I may have grouped OSX and Windows as proprietary operating systems.

It looks like GCC 5 isn't enough for fpm, I get the following:

././src/fpm_command_line.f90:191:12:

             cmd_settings=fpm_run_settings(&
