Support for musl

[MaxVerevkin]

The issue with musl is that it does not implement dlopen. I don't know how it works with X11, but on wayland, wayland-sys tries to open libwayland-client.so which is not possible.

The issue with musl is that it does not implement dlopen.

Isn't it the case that dlopen works with a dynamically linked musl, but not a statically linked musl?

Either way, I think it's an interesting idea to optionally allow regular (non-dlopen) linking to wayland libs and/or xlib and friends.

Hi, just a note for anyone having a problem with this, here is how I get around this:

Either run your cargo commands like this:

RUSTFLAGS="-C target-feature=-crt-static" cargo build

Or put this in ~/.cargo/cargo.toml:

[build]
rustflags = ["-C", "target-feature=-crt-static"]

That indeed does the job, thanks! In my case I didn't have this issue with rustc from my distro repositories but I did with the rustup toolchain.

However the ~/.cargo/cargo.toml approach doesn't seem to do the job, my program fails to launch on Wayland again.

Winit works with musl for years, though you'd have to do -crt-static as it was said. There're also options to disable dl features on wayland at least.

I would like to see support for musl

what do you mean by that? clearly musl is supported (system install), e.g. alacritty works on alpine for years.

it crashes on trying to open a window when using musl and attempting to use RUSTFLAGS="-C target-feature=-crt-static" just fails to compile due to not finding floorf
