Golang and GUI toolkits on FreeBSD

[Sam Fourman Jr.]

Hello list,

I am trying to toy around with some sort of gui toolkit to build a X11 app
it turns out that I cant compile anything, not wx or gtk3 etc..

I am wondering if because clang is the default compiler on FreeBSD that is
causing me issues.
I would like to get to the bottom of how to fix this, so we can make a note
in the FreeBSD port so that others know. so please ask questions lets
figure out what is going on, it could be that I am missing something simple
(Eg, FreeBSD has  everything in /usr/local )


I really would appreciate any help at knowing how to fix this.


here is a example below of yet another toolkit that wont compile
when trying to build the sample code on this page:

https://github.com/andlabs/ui/wiki/Getting-Started


I get this:

go build gui.go

followed by a bunch more errors that I dont think are relevant.
