[SOLVED] install multiple versions of g++(or gcc)

Issue

I was wondering if it is possible to install multiple versions of g++ on the same machine without any problem.

I use the almost current gcc for my work(4.6.1). Now for my studies, my teacher has given us an incomplete project to complete and he says we should install gcc 3.4.3 .

please note that I have already read this : Is it possible to install 2 different versions of GCC at the same time? but I don't know what PATH I should set.

Moreover, I would like to use eclipse for both version. So I may need some guidance for that settings too.

Thank you very much

Solution

In bash you could do two scripts like this: first one:

export PATH=/path/to/your/3.4.3/bin:$PATH
eclipse&

and

export PATH=/path/to/your/4.6.1/bin:$PATH
eclipse&

By running one of those, eclipse should use first gcc it finds in your path. Also your default gcc should still be primary, if you don't run any scripts.

BTW: You can probably strike a deal with your professor on what c++ standard he wants you to use (and what libraries), not what outdated version of compiler you should use to compile your code.
