That’s why I called it “official”, not official.

I am trying to evaluate how this would work. Here is what I tried:

mkdir -p /tmp/golang
export GOPATH=/tmp/golang
go get github.com/mstap/godebiancontrol
go install -v -compiler=gccgo github.com/mstap/godebiancontrol
ls -hlR /tmp/golang/pkg/

This results in the following file structure:

/tmp/golang/pkg/:
total 0
drwxr-xr-x 3 michael staff 60 2013-01-02 15:59 gccgo
drwxr-xr-x 3 michael staff 60 2013-01-02 15:59 linux_amd64

/tmp/golang/pkg/gccgo:

drwxr-xr-x 3 michael staff 60 2013-01-02 15:59 github.com

/tmp/golang/pkg/gccgo/github.com:

total 36K
-rw-r--r-- 1 michael staff 34K 2013-01-02 15:59 godebiancontrol.a

Now, obviously this is not dynamically linked. Neither does it use
different host triplets.

How do I make gccgo use dynamic linking?
