I don't think that's high on anyone's list right > now, though. rustc can already produce shared libraries - they're just pretty useless due to two factors: - lack of stable ABI: for every compiler and dependency update, you'd need to recompile everything. And unless work on a stable ABI progresses in upstream Rust, I doubt that gcc-rs can do anything about this. - incompatible compile-time options (i.e. resulting in conditional compilation): different packages depend on crates with different sets of features enabled, sometimes with conflicting options. Even with a stable ABI, you'd need to build crates for all necessary combinations of configurations, and that matrix quickly explodes (i.e. usually exponentially - 2^n builds for for n independent flags). This is a deal-breaker for shared libraries in most cases, and also can't be solved by using a different compiler. (Unless you want to figure out *which* combinations to build, and *only* build these.)
