linux - 从 Linux 为 Mac 创建 go build 时出现问题？

Question

我正在尝试从 Linux 机器为 Mac 创建一个构建。我可以在不启用 CGO 的情况下通过以下通用方式执行此操作。

env GOOS=darwin GOARCH=amd64 go build

使用启用 CGO 的命令

env CGO_ENABLED=1 GOOS=darwin GOARCH=amd64 go build

但是如果我启用 CGO 那么它就不起作用并出现以下错误

# os/user
/usr/local/go/src/os/user/getgrouplist_darwin.go: In function 'mygetgrouplist':
/usr/local/go/src/os/user/getgrouplist_darwin.go:16:11: warning: implicit declaration of function 'getgrouplist' [-Wimplicit-function-declaration]
  int rv = getgrouplist(user, (int) group, buf, ngroups);

如果您要在 linux 上为 darwin 进行交叉编译并且您正在使用 CGO_ENABLED=1，那么您将还需要一个 C 交叉编译器。
