2 All, rак правильно поставить gcc3

Идешь на www.google.com и ищешь linux from scratch

А какие собственно проблемы. Там все вроде безглючно ставиться.

It's good compiler. I have faced several bugs.

One was with 3.0.1 - MPlayer compilation gived internal bug. Just remove all lines in function caused bug and resume Mplayer compilation. (Of course OpenDivX code will be broken)

Second is most likely isn't bug. Several C++ programs need to be linked with some library where some label defined. I just add -lstdc++ to linker options.

And I forgot. You will have to recompile all C++ libs you want to link with. (including QT, KDE libs). But of course you don't have to recompile those which are not linking with programs you build.
