Unable to statically link a native library if there a dynamic library in the same directory.

rustc -L native='/usr/local/Cellar/libplist/2.4.0/lib' -l static=plist-2.0 main.rs

Error output

There were both of a dynamic library file and a static library file in the lib directory.
The program was built successfully, but it was linked with a dynamic library rather than the static library.

I can confirm that this does not happen in my Linux with rustc 1.77.2. @devxu Could you try this in a different MacOS environment other than yours?

(BTW, I don't think the I-ICE Issue: The compiler panicked, giving an Internal Compilation Error (ICE) ❄️ tag is accurate here as the compiler does not actually panic with an internal error.)

On Linux it is possible to use -Bdynamic/-Bstatic to request the linker to link dynamically/statically. macOS doesn't support this however, so rustc doesn't have a way to make the linker pick whether to statically or dynamically link.

Lines 243 to 253 in 6be7b0c

	fn takes_hints(&self) -> bool {
	// Really this function only returns true if the underlying linker
	// configured for a compiler is binutils `ld.bfd` and `ld.gold`. We
	// don't really have a foolproof way to detect that, so rule out some
	// platforms where currently this is guaranteed to *not* be the case:
	//
	// * On OSX they have their own linker, not binutils'
	// * For WebAssembly the only functional linker is LLD, which doesn't
	// support hint flags

I had the same problem with macos m3

Is there any way to temporarily resolve this?

[kekeimiku]

Very bad temporary solution, just in case anyone needs it, I'm putting it here, feel free to ignore my code. Hope this issue will be resolved soon.

// build.rs
    const APPLE: [&str; 2] = ["aarch64-apple-darwin", "aarch64-apple-ios"];
    if APPLE.contains(&target.as_str()) {
        fs::rename(
            path.join("my.dylib"),
            path.join("this.not.static.my.dylib"),
        )
        .unwrap();

        println!("cargo:rustc-link-search={}", path.display());
    }

[devxu]

@kekeimiku In build.rs do these:
The pkg-config crate is recommended, which is easy to get the dependent static libraries.
Copy the all of dependent static library files to the $OUT_DIR/libs, which can be specified as rustc-link-search directory.
