如何生成静态链接的可执行文件? [英] How to generate statically linked executables?
问题描述
我正在尝试使用 Rust 创建一个静态可执行文件.我不是试图静态链接一个特定的库，我试图创建一个根本不使用动态链接的可执行文件.我有以下(其他工作)测试:
I am trying to create a static executable with Rust. I am not trying to statically link a particular library, I am trying to create a executable which does not use dynamic linking at all. I have the following (otherwise working) test:
$ cat hello.rs
fn main()
{
print!("Hello, world!\n");
}
$ rustc hello.rs -o hello
$ file hello
hello: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, [etc]
注意动态链接的解释器/lib64/ld-linux-x86-64.so.2.静态可执行文件具有 静态链接.(在我的例子中，损坏的部分标题大小，尽管如果我能说服 Rust 复制那个，我会很高兴.)
Note the dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2. Static executables have statically linked instead. (And in my case corrupted section header size, although I would be pleasantly astonished if I can convince Rust to replicate that.)
我需要将哪些选项传递给 rustc 以使其生成实际的静态可执行文件(具体而言:即使 file 同意的文件也是静态链接的).
What options do I need to pass to rustc to get it to generate a actual static executable (for concreteness: one which even file agrees is statically linked).
推荐答案
自 Rust 1.19 起，您可以静态链接 C 运行时 (CRT) 以避免这种在 Windows 上非常常见的情况:
Since Rust 1.19, you can statically link the C runtime (CRT) to avoid this very common situation on Windows:
程序无法启动，因为您的文件中缺少 VCRUNTIME140.dll电脑.尝试重新安装程序以解决此问题.
The program can't start because VCRUNTIME140.dll is missing from your computer. Try reinstalling the program to fix this problem.
将此添加到您的 .cargo/config 文件中，使用适合您平台的目标三元组:
Add this to your .cargo/config file, using the appropriate target triple for your platform:
[target.x86_64-pc-windows-msvc]
rustflags = ["-C", "target-feature=+crt-static"]
编辑 .cargo/config 的另一种方法是手动将 -C target-feature=+crt-static 传递给 rustc.
An alternative to editing .cargo/config is to pass -C target-feature=+crt-static to rustc by hand.
