Enable `link-arg` link kind inside of `#[link]` attribute https://github.com/rust-lang/rust/issues/99427#issuecomment-1234443468 > ... > This would help to make `link-arg` usable in `#[link]` attributes and e.g. wrap libc and libgcc into a group (*) in the libc crate like > > ``` > #[link(kind = "link-arg", name = "--start-group")] > #[link(kind = "static", name = "c")] > #[link(kind = "static", name = "gcc")] > #[link(kind = "link-arg", name = "--end-group")] > ``` > > (*) to address cyclic dependencies between them > > This is an analogue of CMake's LINKER: prefix (https://cmake.org/cmake/help/git-stage/command/target_link_options.html#handling-compiler-driver-differences), and was discussed as a possible future extension in the link modifier RFC (https://github.com/rust-lang/rfcs/blob/master/text/2951-native-link-modifiers.md#support-linkarg--string-in-addition-to-the-modifiers). |
