<div dir="ltr">Hello Mark,<div><br></div><div>Don't whitelist a particular one that you think works; blacklist ones that you know don't work.</div><div>Additionally, I wonder if you are actually using the result of the compilers portgroup. You have to tell it to use the compiler from the variants for e.g. CC. See examples on that. If you don't do this, it has no effect on what is used.

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"><div><br></div><div>David</div></font></div><br><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">mark.brethen@gmail.com</a>> wrote:<br></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.
