下载第三方库时遇到的问题 “x86_64-w64-mingw32-g++.exe" is not able to compile a simple test program.

[Horc-zh]

xmake版本是 2.9.5
cmake版本是 3.30.4
g++.exe (Rev1, Built by MSYS2 project) 14.2.0

以下是运行 xmake f -p windows -a x64 -m release --toolchain=mingw -vD 的输出

求助大佬，这个问题要如何解决？

mingw 工具链要配合 mingw 平台使用。

xmake f -c -p mingw --mingw=path/to/sdk

[Horc-zh]

还是不行，我理解错了吗

[star-hengxing]

发生这个问题的原因有很多，猜测是用 vscode 使用 msys2 有关，可以自行谷歌排除。
但按照这两个方法去运行应该是没错的

• 命令行执行 mingw64 进入 msys2 环境，然后直接执行 xmake。因为 xmake 会探测 msys2 相关的环境变量。
• 使用没有 msys2 环境的 mingw 工具链，如 scoop install mingw & xmake f -c -p mingw --mingw=C:/Users/<your name>/scoop/apps/mingw/current

btw, 既然装了 msvc，在 Windows 优先 msvc 比较好

cmake 检测用了 D:/msys64/mingw64/bin/c++.exe 而不是 D:\msys64\mingw64\bin\x86_64-w64-mingw32-g++

一种就是 vscode/msys2 环境有 $CC 干扰了，一种就是 cmake 默认用的编译器不对。。这其实跟 xmake 也没啥关系，是你环境跟 cmake 之间的问题

[Horc-zh]

好的，感谢两位
