rust - Rust 无法构建 64 位 RISC-V 二进制文件

问题描述

我正在尝试在我的台式计算机上构建一个 riscv64gc 二进制文件。我使用 rustup 添加了工具链，它似乎正在编译但没有链接。我没有看到目标三重通过，也没有使用 llvm 链接器？这是怎么回事？

$ cargo build
   Compiling rusty v0.1.0 (/home/gonzo/github/vmscript/programs/rusty)
error: linking with `cc` failed: exit code: 1

error: aborting due to previous error

error: could not compile `rusty`.

To learn more, run the command again with --verbose.

我假设应该使用 lld 。这是我的货物配置：

[build]
target = "riscv64gc-unknown-linux-gnu"

更新：我现在有一个自定义链接器脚本，这使得 ld 停止抱怨，除了它不能构建 riscv64 二进制文件，因为它是系统链接器。只是我还是 riscv64-unknown-linux-gnu 工具链完全坏了？我对 Rust 中的其他 riscv 工具链没有任何此类问题。

它只是实际支持 std 的单个工具链，它几乎感染了 Rust 中的每个包，使得它不可能走 no_std 路线，所以我们来了。

解决方案

定制了哪个链接器？我认为我们有一些问题。实际上，也许使用 update-to-date risc-v-toolchain。

[build]
target = "riscv64gc-unknown-linux-gnu"
rustflags = ["-C", "target-feature=+crt-static"]

[test]
target = "riscv64gc-unknown-linux-gnu"
rustflags = ["-C", "target-feature=+crt-static"]


[target.riscv64gc-unknown-linux-gnu]
runner = "qemu-riscv64"
linker = "riscv64-unknown-linux-gnu-gcc"
ar = "riscv64-unknown-linux-ar"

它运作良好。静态功能适用于在qemu.
