Put this in your build.rs
to use the C pre-processor with Rust.
fn main() {
walk_dir("src")
}
This will pre-process any .cpprs
source files in src/
using
the system C compiler.
See the lzo-macros example.
The C pre-processor will discard any lines beginning with #
, so that e.g.
#[macro_use]
would be thrown away.
