Installing (Cross Compiling) Go 1.5 in Raspberry pi2

Dave Cheney recently wrote a post on cross-compiling and installing Go 1.5 in Raspberry pi2.  I had some time to play around in my Raspberry pi2.

I followed the steps provided by Dave Cheney, during cross-compiling encountered serious power disruption. I had to remove Go 1.0.2 version before kicking of compiling.

 ##### ../test/bench/go1  
 testing: warning: no tests to run  
 PASS  
 ok      _/home/pi/go/test/bench/go1     14.877s  
 ##### ../test  
 ##### API check  
 Go version is "go1.5", ignoring -next /home/pi/go/api/next.txt  
 ALL TESTS PASSED  
 ---  
 Installed Go for linux/arm in /home/pi/go  
 Installed commands in /home/pi/go/bin  
 *** You need to add /home/pi/go/bin to your PATH.

Tip :

Bash terminal will be running cross-compilation in the background. Simultaneously open another terminal session, connect to Raspberry pi2 via SSH and type W command to find out what’s happening with the previous terminal session.
