What did you do?

i installed qt and the bindings for go and i tried to run an example from github but i got this error.

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

Code for the code i was trying to run:
https://pastebin.com/RWK3aeEw

What did you expect to see?

My qt application

What did you see instead?

seems CGO_CFLAGS_ALLOW enviroment variable (https://github.com/golang/go/blob/master/src/cmd/go/alldocs.go#L1038) can help.

You can leave this open if you want it to be added to the list so you don't have to use CGO_CFLAGS_ALLOW
