Mingw-w64-g++ cross compilation error incompatible libraries
问题
我正在尝试使用x86_64-w64-mingw32-g++和-m32选项交叉编译为32位Windows。我只使用标准库，没有额外的内容。
我得到了这个输出：
x86_64-w64-mingw32-g++ -m32 *.cpp -o ../build/rook-win-x86.exe -O3 -Wall

I am trying to cross compile using `x86_64-w64-mingw32-g++` with the `-m32` option for 32bit windows. I am using the standard library only, nothing extra.

It seems the libraries are incompatible.
I found [this](https://stackoverflow.com/questions/30886645/mingw-w64-linker-skipping-incompatible-files-when-searching-for-third-party-stat) question which was about this issue. But the answer there was to use Microsoft's `link.exe` and I want to do it on linux only.
I tried installing `gcc-multilib` and `g++-multilib`. However that did not resolve it.

`-m32` 和 `-m64` 用于告诉 `gcc`/`g++` 你正在针对哪个版本的 Windows 进行编译，特别是在使用本地 MinGW-w64 编译器时。
在 Linux 上进行跨平台构建通常涉及在编译器工具之前添加平台的三元组。
因此，在使用 `g++` 时，使用 `i686-w64-mingw32-g++` 可以针对 Windows 32 位，而使用 `x86_64-w64-mingw32-g++` 可以针对 Windows 64 位。

<summary>英文:</summary>
The `-m32` and `-m64` are to tell `gcc`/`g++` which Windows you are targeting, especially when using native MinGW-w64 on Windows.
On Linux cross platform building usually involved prepending the compiler tools with the platform's triplet.
So in case of `g++` use `i686-w64-mingw32-g++` to target Windows 32-bit and `x86_64-w64-mingw32-g++` to target Windows 64-bit.
