使用 cargo-xwin 交叉编译 rust 程序

背景

需要将 chainsaw 工具从 linux 交叉编译到 winsows x86，该工具使用了 libesedb-sys 库，使用 i686-pc-windows-gnu 交叉编译总报错

和 mingw build failing · Issue #16 · sunsetkookaburra/rust-libesedb 出现的问题类似

方案

首先按 cargo-xwin 官方文档搭建交叉编译环境

git clone https://github.com/WithSecureLabs/chainsaw.git
cd chainsaw
docker run --rm -itd -e XWIN_ARCH=x86 -v $(pwd):/io -w /io messense/cargo-xwin:sha-05c8e72 bash

然后进入该容器安装一些依赖

apt update
apt install -y clang-tools llvm clang
# 如果需要使用 rustup 加速镜像，请设置如下环境变量
export RUSTUP_DIST_SERVER=https://mirrors.tuna.tsinghua.edu.cn/rustup
# 添加 target
rustup target add i686-pc-windows-msvc

如果你需要使用 crates.io 加速镜像，可以参照 crates.io-index | 镜像站使用帮助 | 清华大学开源软件镜像站 | Tsinghua Open Source Mirror 和 crates.io-index镜像_crates.io-index下载地址_crates.io-index安装教程-阿里巴巴开源镜像站

执行命令进行编译

1
cargo xwin build --release --target i686-pc-windows-msvc

报错如下

看看头文件实际是否存在

1
2
$ find / -name '*rocessthreadsapi.h'
/root/.cache/cargo-xwin/xwin/sdk/include/um/processthreadsapi.h

可以看到存在，并且上面的报错中，也包含了这个文件夹

突然想到 windows 上查找头文件大小写不敏感，linux 上大小写敏感，于是进到 /root/.cache/cargo-xwin/xwin/sdk/include/um/ 文件夹，使用 ln -s processthreadsapi.h Processthreadsapi.h 命令一个个建立了软链接，重新编译，成功了。

或者你也可以使用如下命令临时修改下载到本地的 libesedb-sys 库中的源代码

$ find / -name 'libcthreads_condition.h'

修改后重新编译
