Installing Go on Ubuntu

To install Go on my Ubuntu system I used the directions at golang.org/doc/install.html using ~/dev/go as my build location. The initial attempted to run “./all.bash” failed. Go requires bison which can be installed with “sudo apt-get install bison”. The second run of “./all.bash” succeeded and after a couple minutes ~/dev/go/bin contained the 6g set of executables for amd64 (as opposed to 5g for arm or 8g for 386 or something else on other operating systems).

The final step was to add the folowing to my ~/.bash_profile:

1
2
3
4
export PATH=$PATH:~/dev/go/bin
export GOROOT=$HOME/dev/go
export GOARCH=amd64
export GOOS=linux

And then run “source ~/.bash_profile”. Note that you can also get the 8g compiler on the amd64 platform by running “GOARCH=386 ./all.bash” instead of “./all.bash” along with installing gcc-multilib (“sudo apt-get install gcc-multilib”).

Vim Syntax Highlighting

The go repository includes a syntax highlighter file for Go in “go/misc/vim/” which you can copy to your vim syntax directory with “cp $GOROOT/misc/vim/syntax/go.vim in ~/.vim/syntax/”. Then enable the syntax highlighter for go files by editing ~/.vim/ftdetect/go.vim and adding:

1
au BufRead,BufNewFile *.go set filetype=go

Getting the Go Koans

One set is at go_koans: github.com/VictorDenisov/go_koans. A quick git clone and a “make” and you’re all set.

• I’m running Ubuntu 11.10 amd64 but likely very similar install for other versions.

Update: More Go Koans

One of the craftsmen at 8th Light has written go-koans: https://github.com/sdegutis/go-koans!
