Google Go Installation procedure on Ubuntu 9.10 Karmic Koala

This article helps you through the Installation procedure of Google GO on Ubuntu 9.10 Karmic Koala Operating System .

In my older posts on Talkonsomething ,I described about Google GO programming language feature and what new in Google GO .

Step 1 : In order to install Go compilation environment in Ubuntu 9.10 depends on the following environment variables which has to be set prior to Go installation .
—————————————————————————————————————————————

a. $GOROOT : Root of the Go tree , directory to check out the Go project .

• Go to Terminal
• Enter the following command

$ export  GOROOT=/home/your-name/hg

NOTE: Don’t create the directory hg , it will be automatically created when you  check out the code
—————————————————————————————————————————————

b. $GOOS : Name of the Operating System  , since we are using linux this environment variable has to be set with linux.

• Go to Terminal
• Enter the following command

$ export  GOOS=linux

—————————————————————————————————————————————

c.$GOARCH : Name of the target compilation architecture . if you are using

• amd64 for AMD 64 bit processor
• 386 (32-bit x86) Intel 32 bit process and
• arm (32-bit ARM, an incomplete port)

Note: Based on your system configuration set the $GOARCH environment variable with the above list only the values which are bold ones. In my case its Inter 32 so the following will be my  $GOARCH environment  variable .

• Go to Terminal
• Enter the following command

$ export  GOARCH=386

—————————————————————————————————————————————
d.$GOBIN  : Specify any directory   in which the binaries files should be installed.  This specifies the path in which the GO compiler should be installed

• Create a new create called bin  say  in /home/your-name/bin
• Provide read ,write ,execute permission for  the bin directory  .

$ chmod 777  /home/your-name/bin

• Set the $GOBIN path

$ export GOBIN=/home/your-name/bin

• Also set the $GOBIN path in your $PATH with the following command

$ export PATH=$PATH:/home/your-name/bin

• In order to check all the environment is set  type following command

             $ env|grep '^GO'
               GOBIN=/home/your-name/bin
               GOARCH=386
               GOROOT=/home/your-name/hg/
               GOOS=linux

This confirms all the environment variables are set perfectly you are ready for Installation of GO .

Step 2 : Fetch the  GO Source files from the repository  using  Mercurial .

• If Mercurial is not installed on your System , you can install it  with apt-get  command and also from the Ubuntu Synaptic package Manager.Mercurial

         $ sudo apt-get install mercurial

• Fetch the Sources files with the following command it will create a folder called hg in the $GOROOT path and all the files will be cloned from the repository and will be installed in /home/your-name/hg directory

         $ hg clone -r release https://go.googlecode.com/hg/ $GOROOT

• Here is the Snap Shots of the files and the commands once its is executed .



• Snap Shots of the files in /home/your-name/hg directory.

—————————————————————————————————————————————
Step 3 : The Go tool chain is written in C. To build it, you need to have GCC, the standard C libraries, the parser generator Bison, and the text editor ed installed.

$ sudo apt-get install bison gcc libc6-dev ed

—————————————————————————————————————————————
Step 4 : In order to build the Go distribution on Ubuntu run the following commands in the terminal mode

• Change directory  $GOROOT ie /home/your-name/hg  directory

$ cd $GOROOT/src

• After changing it to the Source directory execute the following Command

$./all.bash

• All the associated packages will be installed this will take some time be patient , if every thing goes well , you will get this message after execution

--- cd ../test
N known bugs; 0 unexpected bugs
