Cross-compile for aarch64-linux-gnu #532

Open arya-pathak opened 2 months ago

arya-pathak commented 2 months ago

Has this crate successfully been compiled for aarch64-linux-gnu? I have installed the crate, switched to nightly, added the target and wrote a build script. Here are the contents of build.rs: 

fn main() {
    println!("cargo:rustc-link-lib=gdal");
}

The crates seem to be compiling fine but it breaks at the linking stage. The compiled C binaries of GDAL are for the x86_64 target. Error message:
