Windowsでも使いたいコードがあり、Linux上でWindows向けにクロスコンパイルをしてみたメモ。 rustupを使うと簡単にクロスコンパイルができる。
windows向けのtargetを探す
$ rustup target list | grep win i586-pc-windows-msvc i686-apple-darwin i686-pc-windows-gnu i686-pc-windows-msvc x86_64-apple-darwin x86_64-pc-windows-gnu x86_64-pc-windows-msvc
今回は x86_64-pc-windows-gnu を追加する
rustup target add x86_64-pc-windows-gnu $ rustup target add x86_64-pc-windows-gnu info: downloading component 'rust-std' for 'x86_64-pc-windows-gnu' info: installing component 'rust-std' for 'x86_64-pc-windows-gnu'
これを --target にしてビルドするが、その前に mingw-w64 をインストール

そしてビルドするとエラーが出る。こんな感じで。

既知の問題のようだ。

ひとまずこれで回避できるとのこと。
$ cat .cargo/config [target.i686-pc-windows-gnu] linker = "i686-w64-mingw32-gcc" [target.x86_64-pc-windows-gnu] linker = "x86_64-w64-mingw32-gcc"
できた
$ cargo build --target x86_64-pc-windows-gnu
