编译包含 aarch64 的 C 库的 rust crate 时遇到问题答案

【问题标题】：Trouble compiling rust crates that include C libraries for aarch64编译包含 aarch64 的 C 库的 rust crate 时遇到问题
【发布时间】：2021-01-24 18:10:32
【问题描述】：

我正在尝试在 aarch64 linux docker 容器中编译一个 rust 应用程序以在 raspberry pi 4 上运行。除了包不是纯 rust 并使用 c 库时，我的工作正常。 ring crate 就是一个例子，当我尝试在不设置 ENV TARGET_CC=something 的情况下构建环库时，它会失败并出现以下错误：

在环 build docs 中提到需要设置 TARGET_CC 和 TARGET_AR，当我将 TARGET_CC 设置为 aarch64-Linux-gnu-gcc 时出现以下错误

我不太了解 C 编译器的所有风格以及我需要什么组合才能使其正常工作，但看起来（希望）我只需要一个小的配置或环境变量更改就能够编译所有我在 aarch64 上需要的包。希望有人可以向我指出一些相关文档或为我提供示例或答案，以了解需要将哪些环境变量设置为什么值才能使其正常工作。

【问题讨论】：

快速提问：为什么要编译 aarch64-unknown-linux-musl 而不是 aarch64-unknown-linux-gnu？这对我来说在 aarch64 上工作得很好，根据 github.com/briansmith/ring/issues/713 的说法，为 musl libc 编译可能仍然存在一些问题。
@HHK 为aarch64-unknown-linux-gnu 编译在尝试从临时容器运行二进制文件时不起作用，我需要一个静态链接的二进制文件，如 musl 生成的，否则如果我尝试运行容器我收到以下错误standard_init_linux.go:219: exec user process caused: no such file or directory，因为暂存容器中不存在动态链接库
你能运行RUST_BACKTRACE=1 吗？在 gcc 方面，您有 this。你试过rebooting吗？
请添加适当的回溯，因为我们只能从中猜测。

在复制this file 中提到的here 中的环境变量后，我能够让它工作

我更新后的 Dockerfile 如下所示

ARG APP_NAME="app"
ARG TARGET="aarch64-unknown-linux-musl"
ARG GITHUB_SSH_KEY=""
RUN apt-get update
RUN apt-get install clang llvm -y

COPY --from=0 /etc/passwd /etc/passwd
COPY --from=builder /usr/src/$APP_NAME/target/$TARGET/release/$APP_NAME ./app
USER $APP_NAME

CMD ["./app"]

通过此设置，二进制文件可以从暂存容器中编译和运行，感谢 @HHK 为我指出有关此主题的未解决问题

【解决方案2】：

我使用rust-musl-builder 解决了“无法为环运行自定义构建命令”问题。

这是我所做的：

将目标添加到 rust 工具链：

rustup target add x86_64-unknown-linux-musl

定义别名以运行 docker 容器

alias rust-musl-builder='docker run --rm -it -v "$(pwd)":/home/rust/src ekidd/rust-musl-builder'

使用容器构建您的项目

rust-musl-builder cargo build --release

以下是支持的目标列表：https://doc.rust-lang.org/rustc/platform-support.html
