Ubuntu doesn't work with gcc 3?

[brunorberto]

Hi,

I have ubuntu 9.10 and needed gcc 3 to work with an old academic application. Now, I managed to downgrade gcc, but nautilus and almost everything else won't work. It says, e.g. "/usr/lib/firefox-3.5.7/firefox: /usr/local/lib/libgcc_2.so.1: version 'GCC_4.2.0'not found (required by /usr/lib/libstdc++.so.6).

Anybody knows how to fix this? I need to keep gcc 3 in my machine (the reason why I installed linux).

An alternative is to use a distribution that comes with gcc 3. Anybody knows of one such distribution?

Thanks a lot,
Bruno

I've not tried it but this fellow has compiled gcc-3.3 and gcc-3.4 for karmic:
