The compilers portgroup provides variants that select compilers, rather than being a way to select the compiler in the portfile. It will provide gcc/gfortran (in specific versions). If something like clang doesn't work, you remove it from the variants list. "active_variants" is about compatibility of compilers used by dependences. As far as I know, variants are definitely still the recommended way of handling compiler selection. I suggest you look at some examples to see how to use compilers portgroup. I made many in the science category, such as octopus, sparskit, berkeleygw, libxc.</div><font color="#888888" class=""><div class=""><br class=""></div><div class="">David</div></font></div><br class=""><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jul 2, 2022 at 4:20 PM Mark Brethen <<a href="mailto:mark.brethen@gmail.com" target="_blank" class="">mark.brethen@gmail.com</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">This port does not have config, so I’m having to pass the build args.
