How to cross-compile from linux/amd64 to darwin/arm64 with cgo?
问题
我正在尝试在linux/amd64上交叉编译darwin/arm64，当我使用CGO_ENABLED=1构建代码时，出现了以下错误。我理解这个错误，但我不知道如何解决。
我的代码必须启用CGO_ENABLED功能进行编译。
错误消息：
GOOS=darwin GOARCH=arm64 CGO_ENABLED=1 CC=gcc go build -o dist/darwin-arm64 cmd/main.go
# runtime/cgo
gcc: error: arm64: No such file or directory
gcc: error: unrecognized command line option '-arch'
make: *** [makefile:6: darwin] Error 2

I am trying to cross-compile darwin/arm64 on linux/amd64, I got the below error when I build code with CGO_ENABLED=1, I understand the error, but I don't how to solve.
My code must enable CGO_ENABLED feature to compile.

很可能，你需要安装gcc工具链来进行到arm64的交叉编译。
我知道Debian/Ubuntu有用于Windows和其他Linux架构的交叉编译工具链（例如：gcc-aarch64-linux-gnu、libc6-dev-arm64-cross和gcc-mingw-w64-x86-64软件包）。
我不确定是否有可用于darwin的工具链。

Chances are, you need to install the gcc toolchain for cross-compilation to arm64.
I know Debian/Ubuntu have cross-compiling toolchains for Windows, as well as other Linux architectures (e.g.: packages gcc-aarch64-linux-gnu, libc6-dev-arm64-cross and gcc-mingw-w64-x86-64).
I'm not sure if there is a darwin toolchain available.
