build issue

[glycerine]

from an email

First, thank you for your github repository chezgo, I’m very intereted. But I can’t build chezgo,
when I run “make run”, I got

go build github.com/go-interpreter/chezgo: invalid flag in #cgo LDFLAGS: ./chez_scheme_9.5.1/boot/a6osx/kernel.o
How can I fix this?

my reply:

This is due to the recent whitelisting of all cgo flags, which appears to be busted yet again.

Use the CGO_LDFLAGS_ALLOW env variable to work around it for now.

I noted the issue on golang/go#23749 at the end of the comments.
