從Linux為Mac創建go build時出現問題？

Question

我正在嘗試從linux機器為Mac創建一個構建。 我可以在不啟用CGO的情況下通過普通方式做到這一點。

env GOOS=darwin GOARCH=amd64 go build

使用啟用CGO的命令

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

但是，如果我啟用CGO，它將無法正常工作並出現以下錯誤

# 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);

如果要在linux上針對darwin進行交叉編譯，並且正在使用CGO_ENABLED=1 ，則還需要一個C交叉編譯器。
