In a bash shell you can do something like this:
./configure CC=gcc-2.95
There will be similar techniques for other shells but I couldn't help you with the specifics. If your project is C++ the variable you need to define is CXX.

I don't even know how to call the wished version without configure... I type only g++. – Oodini Apr 12 '10 at 12:15

Actually, on my system, it was gcc-4.1 for gcc-4.1.2. Thanks. – Oodini Apr 12 '10 at 12:30

14This works, but is discouraged. The recommended way to specify CC is in an argument to configure, not in the environment. In other words, you should do "./configure CC=/path/to/desired/compiler". – William Pursell Apr 15 '10 at 15:31

Actually, I needed `./configure CXX=g++-4.9` – Cookie Apr 07 '16 at 08:27

is there a way to specify the compiler version even more, like: gcc-4.8.2? – Maximilian Jun 13 '16 at 13:15

@WilliamPursell I just find out if you build you own GCC compiler then only your case works. Thank you buddy! – Li haonan Sep 11 '20 at 02:00

Note that my comment from 2010 is no longer applicable, as the answer has been edited to include the recommended change. – William Pursell Sep 11 '20 at 12:26
