如何为riscv64gc-未知-linux构建一个Rust程序？
提问于 2022-11-13 20:18:11
我正试图交叉编译一个用于第3层平台riscv64gc-unknown-linux-musl的Rust程序，但我认为无论是链接还是正确地指导货物，都会遇到问题。
我试过跑步：
cargo +nightly build -Z build-std --target riscv64gc-unknown-linux-musl正如这个问题的答案和这个问题的答案所指出的，会导致大量错误：
= note: /usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find crtbegin.o: No such file or directory
/usr/bin/ld: /home/lindon/Projects/Rust/open_computers_lib/target/riscv64gc-unknown-linux-musl/debug/deps/open_computers_lib-0a95fe466728767f.1n96vpe9sdkbhvag.rcgu.o: Relocations in generic ELF (EM: 243)
/usr/bin/ld: /home/lindon/Projects/Rust/open_computers_lib/target/riscv64gc-unknown-linux-musl/debug/deps/open_computers_lib-0a95fe466728767f.1n96vpe9sdkbhvag.rcgu.o: Relocations in generic ELF (EM: 243)
...(编辑用不同文件名重复的最后一行的较长列表)
我还尝试使用来自这里的预构建交叉编译工具链，以及尝试从这里构建工具链，然后使用以下脚本：
export PATH="/opt/riscv-musl/riscv64-unknown-linux-musl/bin/:$PATH"
cargo +nightly build -Z build-std --target riscv64gc-unknown-linux-musl # same as before这给了我(对于预先构建的工具链和亲自构建的工具链的相同错误日志)：

...nightly-x86_64-unknown-linux-gnu在std路径中的存在使我相信我可能是在错误地指示货物，或者仅仅是因为我的主机系统是x86_64-unknown-linux-gnu。
可能具有重要意义的补充资料：
- 这个程序只有一个空的
main函数。 - 所有测试都是在运行完整的系统升级和运行
rustup update之后完成的，我在项目中使用了2021年版的Rust。 - 我在运行Arch Linux。

先决条件/假设
这个答案假设如下：
- 您正在运行Linux。
riscv linux muslC交叉工具链安装在/opt/riscv-musl/上。- 你每晚都要安装铁锈。
- 如果没有，运行
rustup toolchain install nightly
- 如果没有，运行
使用说明
具有如下所示的Rust项目文件夹结构：
├── src/
├── .cargo/
│ └── config.toml
└── compile.sh内部config.toml
[target.riscv64gc-unknown-linux-musl]
rustflags = [
"-C", "target-feature=-crt-static"
]
linker = "riscv64-unknown-linux-musl-gcc"
ar = "riscv64-unknown-linux-musl-ar"内部compile.sh
export PATH="/opt/riscv-musl/bin/:$PATH"
cargo +nightly build -Z build-std --target riscv64gc-unknown-linux-musl如果riscv64-unknown-linux-musl-gcc和riscv64-unknown-linux-musl-ar已经在$PATH上了，那么compile.sh中的export语句就没有必要了。
现在，如果您想编译到riscv64gc-unknown-linux-musl目标，只需运行compile.sh。
更多信息
为了获得我最终获得的Functionalconfig.toml，我采取了以下步骤：
[target.riscv64gc-unknown-linux-musl]
rustflags = [
"-L/home/blackdragon2447/x-tools/riscv64-unknown-linux-musl/riscv64-unknown-linux-musl/sysroot/lib",
"-L/home/blackdragon2447/x-tools/riscv64-unknown-linux-musl/lib/gcc/riscv64-unknown-linux-musl/11.2.0/",
"-L/home/blackdragon2447/x-tools/riscv64-unknown-linux-musl/riscv64-unknown-linux-musl/sysroot/usr/lib",
"-C", "link-args=-lc",
"-C", "prefer-dynamic",
"-C", "target-feature=-crt-static"
]
ar = "riscv64-unknown-linux-musl-ar"
linker = "riscv64-unknown-linux-musl-gcc"如果这个答案中的那个由于某种原因不能工作，那么就试着使用它(不要忘记改变其中的路径)。
