GCC构建时未定义的引用
GCC构建时未定义的引用
提问于 2018-05-11 08:36:58
我正在尝试使用golang为windows amd64构建一个可执行文件。除了"go run“或"go build”之外，一切都运行得很顺利。构建过程在编译来自github.com/andlabs/ui的包的时候中断了。跟踪过程如下：

collect2.exe: error: ld returned 1 exit status我最初尝试从linux交叉编译到windows时遇到了大致相同的问题，所以我猜这是一个我应该用来构建它的标志的问题，或者我可能遗漏了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，我决定我应该迁移到Windows并进行本机编译，但这似乎行不通。
我愿意提供更多的信息，您可能需要帮助我弄清楚这一点。

根据the installation instructions for the ui package，您将需要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
