Installing g77 in Ubuntu intrepid (8.10), Jaunty (9.04), Karmic (9.10), Lucid (10.04), Maverick (10.10), Natty (11.04)

g77 is a part of gcc (GNU Compiler Collection) provided by GNU. But GNU stopped supporting it from gcc-4.2. Current Ubuntu versions starting from Ubuntu 8.10 (Intrepid) are using gcc-4.2 or higher. Current Ubuntu Maverick is using gcc-4.5. So to install g77 we need to install gcc-3.4. This package is included in the "universe" repositories of Ubuntu "hardy" distribution. Hence to install g77 in Ubuntu Intrepid, Jaunty, Karmic, Lucid, Maverick versions we need to add the hardy universe repository to the sources.list. Here is the procedure for it.




Press Alt+F2 and type

gksudo gedit /etc/apt/sources.list



The file will look like this.





Search for #deb and #deb-src and delete the # symbol before deb

Don't delete the # symbol before deb cdrom

The final file should look like this. You may need to remove four times # symbol.




Find out the four lines with universe and copy them.




Paste them at the end of the file. Edit the word maverick and replace with hardy as shown below. Now save the file and close.



Now open "synaptic package manager"

It will be in System --> Administration --> Synaptic Package Manafer"



Now one will see this. Click on "Close"



Now click on "Reload"






Now type g77 "Quick Search" box...



Now right click on g77 and select "Mark for installation"




Select "Mark" for additional changes if required...





Now click on "Apply"



A summary of the new changes will look like this. Click on "Apply"



Now the system will download the packages..



Then it will install..



If installation is success you will see this..

If it is success.. click on "Close"



Now one can see a tick mark before "g77" in the synaptic package manager like this..



Simplest way is:

add to /etc/apt/sources.list the ubuntu 8.04 hardy repositories as superuser:

deb http://in.archive.ubuntu.com/ubuntu/ hardy universe
deb-src http://in.archive.ubuntu.com/ubuntu/ hardy universe
deb http://in.archive.ubuntu.com/ubuntu/ hardy-updates universe
deb-src http://in.archive.ubuntu.com/ubuntu/ hardy-updates universe

then in the terminal:

sudo apt-get update
sudo apt-get install g77

For Ubuntu 8.10 you should use this after adding hardy repos

sudo aptitude update
sudo aptitude install g77

Enjoy....
