Building on windows with msys and gnu toolchain fails #60

Open AidaPaul opened 4 years ago

AidaPaul commented 4 years ago

Sadly my attepts to get it up and running with gnu toolchain + msys on windows yielded no luck.

toolchain: stable-x86_64-pc-windows-gnu

cargo build:

This is separate from #45 as that issue tries to build with MSVC toolchain. Any help would be greatly appreciated!

rucoder commented 3 years ago

I managed to make it working with mingw64 from msys2. The main problem is that it is incorrect to make decisions only checking
#if (defined(_WIN32) || defined(_WIN64)) we also need to check #if defined (_MSC_VER) or defined(__MINGW32__) || defined(__MINGW64__). Also build.rs should check not only for target OS but also check the toolchain

fn find_link_lib<P>(install_path: P) -> Option<(PathBuf, &'static str)>
where
    P: AsRef<Path>,
{
    let install_path = install_path.as_ref();
    let lib_dirs = &["lib", "lib64"];

    let lib_base = link_lib_base();

    let lib_file = if cfg!(windows) {
        if cfg!(gnu) {
            format!("lib{}.a", lib_base)
        } else {
            format!("{}.lib", lib_base)
        }
    } else {
        format!("lib{}.a", lib_base)
    };
