What did you do?

I write a demo to reproducing the error.

I try to cross compile a plugin in macOS to ARM platform(RPi Zero W), but got an error.

$ git clone https://github.com/PeerXu/error-golang-cross-compile-with-plugin.git
$ cd error-golang-cross-compile-with-plugin
$ make
GOOS=linux GOARCH=arm GOARM=5 go build -o plugin.so -buildmode=plugin plugin/plugin.go
# command-line-arguments
loadinternal: cannot find runtime/cgo
/usr/local/opt/go/libexec/pkg/tool/darwin_amd64/link: running clang failed: exit status 1
clang: error: invalid linker name in argument '-fuse-ld=gold'

make: *** [all] Error 2

What did you expect to see?

Compile pass without any error.

What did you see instead?

# command-line-arguments
loadinternal: cannot find runtime/cgo
/usr/local/opt/go/libexec/pkg/tool/darwin_amd64/link: running clang failed: exit status 1
clang: error: invalid linker name in argument '-fuse-ld=gold'

dupe of #18157

You need to install a C cross-compiler and then set the following environmental variables:

CGO_ENABLED=1
CC=replace-this-with-the-arm-cross-compiler

If you require further help please ask around in one of the places listed in https://github.com/golang/go/wiki/Questions as the bug tracker is only for bug reports.
