This is a problem when I try to cross-compile a project with generated code (x86_64 + arm). As OUT_DIR seems to be always linked to default out directory (<my_project>/target/debug/build/.../out), generated code can't found with arm targ...
编写build.rs文件,如下: use std::env; use std::fs::File; use std::io::Write; use std::path::Path; fn main() { let out_dir = env::var("OUT_DIR").unwrap(); let dest_path = Path::new(&out_dir).join("hello.rs"); let mut f = File::create(&dest_path).unwrap(); f.w...
