error when build build staticlib #3688

I try build a static lib file libwebrender.a to be used with cpp project with RUSTFLAGS="--crate-type=staticlib" cargo build --release --lib

Is this the correct way to build static lib ?

is there a c/cpp header file for the rust api to be used for cpp project?

You'd want to look at webrender_bindings, which is the Gecko wrapper around WR that exposes a C API. Gecko build system then runs cbindgen on it in order to obtain the C header.
