How to call a batch builder script on a Rust cargo build script?
The project rust-onig requires to compile the oniguruma C project. This is originated from the question error: failed to run custom build command for `onig_sys v61.1.0` which attempts to build oniguruma on windows. Afterwards was noticed on windows within Visual Studio 2015, we need to call the make_win32.bat, instead of cmake to build the oniguruma C project.
However I have no idea how to do the cargo builder to call the make_win32.bat build script. Based on build-script, I edited the default builder build.rs which is attempting to use cmake instead of make_win32.bat:
extern crate pkg_config;
extern crate cmake;
// use std::env;
// fn compile_with_cmake() {
// use cmake::Config;
// let static_link = env::var("CARGO_FEATURE_STATIC_ONIG").is_ok();
// // Builds the project in the directory located in `oniguruma`, installing it
// // into $OUT_DIR
// let mut c = Config::new("oniguruma");
// let dst = if static_link {
// c.define("BUILD_SHARED_LIBS", "OFF")
// } else {
// c.define("CMAKE_MACOSX_RPATH", "NO")
// }
// .build();
// let link_type = if static_link {
// "static"
// } else {
// "dylib"
// };
// println!("cargo:rustc-link-search=native={}",
// dst.join("build").display());
// println!("cargo:rustc-link-lib={}=onig", link_type);
// }
pub fn main() {
println!("Opening MAIN!!!!!!!!\n\n\n\n");
use std::process::Command;
let status = Command::new("D:\\User\\Downloads\\rust-onig\\onig_sys\\oniguruma\\make_win32.bat").status().unwrap_or_else(|e|
{
panic!("failed to execute process: {}", e)
});
println!("process exited with: {}", status);
println!("process exited with: {}", status);
println!("process exited with: {}", status);
println!("process exited with: {}", status);
println!("process exited with: {}", status);
// if let Ok(_) = pkg_config::find_library("oniguruma") {
// return;
// }
// compile_with_cmake();
}
But my builder script is not called, as the message process exited with is never showed:

What is displayed, when do we attempt to used the cmake builder can be viewed on the question This is originated from the question error: failed to run custom build command for `onig_sys v61.1.0`
The problem there is cmake is generating several Visual Studio projects, which purely do not know how to build oniguruma. The only solution able to effectively build it is the make_win32.bat which already comes within oniguruma. Moreover, we need to use the make_win32.bat instead of let cmake generating Visual Studio.
