I want to install NS2 in Ubuntu.

I run the below command:

sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3 

But I got an error:

Package gcc-4.3 is not available
E: Package 'gcc-4.3' has no installation candidate.

Could you please provide me how to install gcc-4.3 [Step-by-Step]??

Try with gcc-4.4 – Leo Jun 2 '13 at 15:06

Install the metapackage gcc. This will automatically install the latest available version of gcc, so you won't need to worry about the details. If you need an outdated version for this particular program to build, gcc-4.4 is the oldest you can get through the package manager.

To clarify, that's sudo apt-get install gcc or sudo apt-get install gcc-4.4

I'm not aware of any archives that have the particular 4.3 release that you're looking for. I am assuming that any version will work just as well, and that NS2 merely provided old build instructions.

I still think the latest version would work, but I decided to try answering your actual question and I discovered this website which provides old GCC versions: I downloaded one, and it had HTML installation instructions in it. – Wutaz Jun 3 '13 at 19:49
