As this is the way gcc compiles:
- compile an mini-gcc (stage1/xgcc) with any *cc installed
- compile another (stage2/xgcc) with stage1/gcc
- compile whole gcc (stage3/xgcc) with stage2/xgcc
- while (
differ(
code_produced_by_stageN_gcc,
code_produced_by_stageN-1_gcc
)) {
- compile stageN+1_gcc with stageN_gcc
- N++
}
it should not matter what gcc version is installed .. objections?

Make sure you copied the codecs.conf file to your ~/.mplayer directory. I looked at the spec file and it has MMX disabled so that shouldn't cause problems. You might want to rpm -ivh MPlayer then goto the spec file and remove the 'libstdc++3.0-devel' option from BuildRequires and if your using gcc-2.96 replace --cc=gcc-3.01 with --cc=gcc in the %configure line then rpm -bb MPlayer.spec.
Re: [Cooker] MPlayer team and mdk gcc
Hi,
I use MPlayer as a way of playing pertty much all my multimedia with
linux. On the MPlayer website and in it's configure routine, it claims
that the gcc 2.96 that ships with Mandrake is broken (something about
MMX being done incorrectly...?).
I am not aware of that specific problem (MMX), Red Hat either:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=47817
It also claims that the 3.01 shipped with Mandrake cooker is broken as
it was compiled with gcc 2.96.
Gcc is bootstrapped. Say we want to build gcc3 with the current
development tools (e.g. gcc-2.96):
- The system C compiler (currently 2.96) builds stage1 C compiler.
- Stage1 C compiler builds stage2 compiler(s).
- Stage2 compiler builds stage3 compiler(s).
- The stage3 compiler is then compared to stage2 compare and if they are
the same, that's good. Stage2 and stage3 compilers should identical.
- Finally, the stage3 compiler(s) are used to build the remaining libs
(libstdc++-v3, libjava, etc.).
In short, the resulting gcc3 was compiled with... gcc3.
The following document is not GCC-specific but you may find it
interesting:

Given that I'm not in any position of authority, and that the mplayer team have had enough of being asked about the gcc issue (flames only now). May I ask that one of you mdk guys get on to them (mplayer.dev.hu) and see if they can't explain what they think is wrong so youo can see about fixing it? Apologies for being dim, but it bothers me that MPlayer says that it will compile, but I can't complain that it doesn't work. Cheers Alex
