In order to use Go you need to set the following in your ~/.profile:
|
|
|
|
export GOROOT=`brew --prefix`/Cellar/go/#{version}
|
|
export GOARCH=#{ENV['GOARCH']}
|
|
export GOOS=#{ENV['GOOS']}
|
|
|
|
Presumably at some point the Go developers won't require us to mutilate our
|
|
shell environments in order to compile Go code...
