在macOS下启用CGO_ENABLED的交叉编译

在启用CGO_ENABLED的情况下,尝试使用下面命令进行Windows平台的交叉编译:

$ CGO_ENABLED=1 GOOS=windows GOARCH=386 go build -x -v -ldflags "-s -w"

出现错误如下:

# runtime/cgo
gcc_libinit_windows.c:7:10: fatal error: 'windows.h' file not found

安装mingw-w64

编译x64

可执行文件

$ CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ GOOS=windows GOARCH=amd64 go build -x -v -ldflags "-s -w" -o test_x64.exe

静态库

$ CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ GOOS=windows GOARCH=amd64 go build -buildmode=c-archive -x -v -ldflags "-s -w" -o bin/x64/x64.a main.go

动态库

-buildmode=c-archive改为-buildmode=c-shared即可
