编译Rust自定义目标时遭遇链接器错误,重装Rust无效最终通过修复binutils解决
编译Rust自定义目标时遭遇链接器错误,重装Rust无效最终通过修复binutils解决
问题场景
我最近跟着教程尝试用Rust编写操作系统,使用自定义的x86_64-blog_os.json目标文件编译项目时,突然触发了链接器错误,具体报错内容如下:
error: linking with 'cc' failed: exit status: 1 | = note: LC_ALL="C" PATH= ...... ..... = note: /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/Scrt1.o: unrecognized relocation (0x2a) in section '.text' /usr/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status error: could not compile 'compiler_builtins' (build script) due to previous error
一开始我误以为是第一次安装Rust时中途中断安装脚本导致的问题,于是卸载并重装了Rust,但问题完全没有改善。后来我还发现,不管编译任何Rust项目都会出现这个错误,更新Rust nightly工具链也没能解决问题。
相关配置信息
我的自定义目标文件x86_64-blog_os.json内容:
{ "llvm-target": "x86_64-unknown-none", "data-layout": "e-m:e-i64:64-f80:128-n8:16:32:64-S128", "arch": "x86_64", "target-endian": "little", "target-pointer-width": "64", "target-c-int-width": "32", "os": "none", "executables": true, "linker-flavor": "ld.lld", "linker": "rust-lld", "panic-strategy": "abort", "disable-redzone": true, "features": "-mmx,-sse,+soft-float" }
.cargo/config.toml配置:
[unstable] build-std = ["core", "compiler_builtins"]
Cargo.toml配置:
[package] name = "blog_os" version = "0.1.0" edition = "2018" [dependencies]
使用的工具链:nightly-x86_64-unknown-linux-gnu (default),rustc版本1.72.0-nightly
最终解决方法
经过排查,发现问题根源在系统的binutils工具包上。只需要执行以下命令卸载并重装该工具包,就能彻底解决链接器错误:
sudo apt purge binutils sudo apt install binutils
