How to pass -L linker flag to rustc for cargo based project?

Question

How do I make cargo pass -L linker flag to rustc invocations?

Answer 1

It is now possible using .cargo/config.

See https://github.com/rust-lang/cargo/issues/1109 and http://doc.crates.io/config.html.

Answer 2

Not yet. However, you can use a custom makefile for given Cargo project instead.

For example, Servo uses the Skia library by having a Rust wrapper in the same cargo project, and a build key that calls a custom makefile.

You can do something similar in this case, for now.
