如何在 Rust 货物构建脚本上调用批处理构建器脚本？

如何在 Rust 货物构建脚本上调用批处理构建器脚本？

项目 rust-onig requires to compile the oniguruma C project. This is originated from the question 试图在 windows 上构建 oniguruma。后来在 Visual Studio 2015 年 windows 上注意到，我们需要调用 make_win32.bat 而不是 cmake 来构建 oniguruma C 项目。

但是我不知道如何让 cargo 构建器调用 make_win32.bat 构建脚本。基于 build-script, I edited the default builder build.rs 试图使用 cmake 而不是 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();
}

但是我的构建器脚本没有被调用，因为消息 process exited with 从未显示过：

显示什么，我们什么时候尝试使用cmake构建器可以在问题上查看这是源于问题

存在的问题cmake生成了几个Visual Studio项目，完全不知道如何构建oniguruma。能够有效构建它的唯一解决方案是 make_win32.bat，它已经包含在 oniguruma 中。此外，我们需要使用 make_win32.bat 而不是让 cmake 生成 Visual Studio.

我在 -vv 中调用了它，正如 user1034749 评论的那样，它输出正确并且运行 make_win32.bat 文件。

我只需要在 make_win32.bat 中放入命令 cd D:\rust-onig\src 因为批处理文件运行在其他地方的某个文件夹中。
