gmsh-sys

Unofficial bindings to the Gmsh C API (currently v4.4.1). The bindings are directly generated using bindgen. They're very low-level and you'll likely want them wrapped in a higher-level crate.

You'll need a copy of the Gmsh SDK library (libgmsh) to link with.

If you're getting linker errors when trying to run cargo test, try passing the Gmsh library location to LD_LIBRARY_PATH during the call:

LD_LIBRARY_PATH="<libgmsh-path>" cargo test

For posterity, the exact bindgen call (v0.50.0) was

let bindings = bindgen::Builder::default()
                .header("gmsh/api/gmshc.h")
                .generate_comments(true)
                .generate()
                .expect("Unable to generate bindings");

    let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
    bindings
        .write_to_file(out_path.join("bindings.rs"))
        .expect("Couldn't write bindings!");
