    Debian switches to GCC 3.2 as default compiler
    Submitted by ametzler on Wednesday, January 08, 2003 – 09:09
    DebianRyan Murray posted some great news to debian-devel-announce yesterday. After long preparations and tests (and waiting for gcc to compile and work properly on m68k – Robot101) Debian has finally changed the default compiler (available as “gcc” and “g++”) to gcc 3.2 on all architectures in sid.

    Because gcc 3.2 changes the C++ ABI (you cannot link an application against two different C++ libraries, one compiled with gcc 2.95, the other compiled with gcc 3.2) the transition required careful preparations, and the change requires that the package maintainers follow the transition plan.

    Thanks to the gcc maintainers and all the other people who made this possible.

    Subject: i’ll have to do this for the first time

    actually, i haven’t done any upgrade yet – this is gonna be my first time 🙂 and as I said, i use woody now. the question is does it seem to be safer now or i’d better wait (how long?) until the trastition is complete? i mean, can it break some dependencies because of the fact that one package is compiled with 3.2.1 and another one was compiled with 2.95???

    Subject: break dependencies

    Well, it will “break” dependencies, meaning, that you will not be able to install/upgrade certain packages yet because they conflict with packages that you need. (i.e. “not be able to”, not “should care not to do”. Let dpkg care for it 😉

    Just read what apt/aptitude/… suggests and decide carefully. (Rather hold back some packages instead of removing packages that you might need.) Upgrade important packages first (e.g. dpkg, aptitude)

    The newly compiled C++ libraries will have different package names (c102 suffix), so you can still choose between the g++-3.2.x or earlier versions. I expect there will be a period of some days, when upgrading becomes difficult, because of some packages being already recompiled, while some are still waiting to be. Again, nothing you really have to worry about.

    The worst thing that i can imagine to happen is, that you end up with some packages still being from woody for a week or two, while others are sid.
