使用Golang进行Mac交叉编译（或替代）

Question

Ok so I'm trying to compile my Awesomium go wrapper on my mac (everything works fine on linux). My problem is, when I try to compile I get

ld: warning: ignoring file /Library/Frameworks//Awesomium.framework/Awesomium, file was built for i386 which is not the architecture being linked (x86_64): /Library/Frameworks//Awesomium.framework/Awesomium Undefined symbols for architecture x86_64:

Fine. But that raises a few questions. First, I didn't have the option to download a x86_64 version for Mac, it was "the mac version" no architecture. Second, I checked a few other libraries and it seems like nothing is built x86_64.
Now I thought maybe I could make a i386 version just for osx but it seems it's extremely difficult, some say impossible, to cross compile cgo.

What are my options?

I'm not sure if you're going to run into any other problems with the universal binary, but building an i386 go toolchain is fairly easy.

http://golang.org/doc/install/source

You can then set the GOHOSTARCH and GOARCH environment variables, e.g.

GOHOSTARCH=386 GOARCH=386 ./all.bash
