You can download it and build it yourself from http://gcc.gnu.org. You should install it in a separate directory, e.g. /opt/gcc-4.3, so as not to mess with the existing gcc on your system. You should *not* attempt to replace your existing gcc, just install the older version in a separate directory and set your PATH and LD_LIBRARY_PATH appropriately when you want to use it.

What do you need such an old version for, anyway?

@vishakha singhal : Welcome to LQ.

The Ubuntu 12.04 default compilers are gcc-4.6, gcc-4.5, gcc-4.4 .

Ref. your other post : ns-2.34 + leach :
GCC-4.3 worked OK with Ubuntu 10.04, until 10.04 got updated.
Since then ( 3 years ago ) you will have to use gcc / g++ version 4.1.2 .
( If it's a 64bits OS, g++-4.4 may work.)
* Generally :
* Do not use three year old install advices, read the current instructions:
. http://www.linuxquestions.org/questions/tags/leach/
. http://www.linuxquestions.org/questions/tags/pegasis/

GCC and g++ version 4.1.2 : See post #18 here ...

As someone has already suggested - why do you need GCC 4.3?

Is it because a newer version throws errors for some poorly written or ambiguous code? If it does - I owuld look at fixing the offending code.
