[SOLVED] multiple versions of gcc

[monkeyking]

Is it possible to have multiple version of gcc installed on the same ubuntu installation.

And if so, how do I choose which to use.


thanks in advance

This is exactly as complicated as I thought it would be.

I remember a java utility,
that made it possible to change version,
with the click of a button.

This would be nice

perhaps you can use update-alternatives command. Look at this http://http://ubuntuforums.org/archive/index.php/t-80145.html

Good luck

It's not complicated, if you're using the multiple versions available from the Ubuntu repositories... all you have to do is invoke the non-default versions like so:

gcc-3.4

instead of just:

gcc

In a makefile, you should be able to achieve the same result by putting a line like "CC = gcc-3.4" at the top.

gcc-3.4

Do you know,
if this approch will use the proper "old" includes?

I currently use g++ 3.4, 4.2 and 4.3 for development. Header files are not compatible and it works just fine.
