go - GCC 未定义的构建引用

Question

我正在尝试使用 golang 为 windows amd64 构建一个 exe。除了“go run”或“go build”之外，一切都运行顺利。构建过程中断了来自 github.com/andlabs/ui 的包的 gcc 编译。跟踪如下:

我最初尝试从 linux 交叉编译到 windows，但问题大致相同，所以我想这是我应该用来构建它的标志的问题，或者我可能缺少一些与依赖相关的东西......

我尝试使用 CGO_ENABLED=1 和 linux 上几乎所有其他可能的标志组合进行交叉编译，有时会触发错误

gcc: error: unrecognized command line option ‘-mthreads’

最终我决定我应该转移到 Windows 并进行 native 编译，这似乎不起作用。

我愿意提供您可能需要的任何更多信息来帮助我解决这个问题。

根据the installation instructions for the ui package你需要 install MingW并设置一些环境变量来构建它:

set CGO_ENABLED=1
set CC=C:\PROGRA~1\mingw-w64\x86_64-7.2.0-win32-seh-rt_v5-rev1\mingw64\bin\gcc.exe
set CXX=C:\PROGRA~1\mingw-w64\x86_64-7.2.0-win32-seh-rt_v5-rev1\mingw64\bin\g++.exe
go build -ldflags -H=windowsgui
