Created attachment 920810 [details] Build log
https://github.com/SFML/SFML/issues/2670 May be fixed upstream in 3.0
Relevant upstream patches: https://github.com/SFML/SFML/commit/f371a99b398f8cd2eedb79c6d68ee00ddea0a9cb https://github.com/SFML/SFML/commit/9022d9564de071e944d20f3419bb6203c46b7a2b
And those patches are ABI-breaking, because C++ mangling. So, only solution: Limit current consumers to 2.6.2, and someone needs to port them to 3.0.0 if they want them to work on clang.
What should users like myself do in the event we need this package to build (for at least 2.6.2) but can't? Those Gentoo github pull requests were closed, so I don't see any relevant patches to resolve this in the meantime :/
