Fails to link with musl libc #595

Open kv-o opened 2 months ago

kv-o commented 2 months ago

Go version: 1.20 Go-SDL2 version: 0.4.38 SDL2 version: 2.26.5 OS: Alpine Linux 3.18.2 Architecture: amd64

Any attempt to build a basic go-sdl2 program on Alpine Linux fails due to undefined references to libc functions. My assumption is that go-sdl2 expects glibc, and as a result fails to link with my system's musl libraries.

Hi @kv-o, yes we built the static libraries using glibc. There is no plan to support musl at the moment as we lack maintainers but PRs would be accepted!
