GREAT!
Six weeks ago, I built a system from ground-up with GCC 3.3 -- I ended up having to use a lot of CVS sources (for gcc itself, grub, and mozilla) in order to get everyone to play together.
Glad to see that things are settling down. (if you can call it that...)
Seriously, we do some technical computing here, and have found that gcc 3.3 emits better code in some cases. Mostly for the FORTRAN stuff.
I ran into problems with my gcc-3.3 gentoo system, namely glbc seemed to be b0rken when compiling static apps, so I've reverted back to 3.2.3 -- I missed the ProPolice patches anyhow.
But gcc 3.3 is way better at agressive optimizations, I think. And like I said some folks here think the gcc 3.3 is better for numerical computation.
But I could see little difference for a desktop/programming workstation. (I run ~x86, PIII Coppermine laptop) |

In my third attempt to make this post.... apparently there are some stability issues in the 2.6 kernels.... ;] i think i may have it fixed however...
anyways... on to responding to some of the posts...

well, libnids is a dependant of dsniff, but so is a depreciated libnet that i cannot get to compile w/ gcc 3.3 either... and as it is depreciated, i am a bit hesitant to leap into debugging it.
however, sniffit is fixed... grab it from...

gcc 3.3 is probably better all around at optimizing... but especially on athlons due to the work that has gone into the Hammer x86-64 architecture... biggest thing for your p3 coppermine is probably the "-mfpmath=sse", which may well work better in 3.3 than in previous versions, but i have no conclusive evidence of that, nor have i heard of any...
as to a general description of what i have patched up to get my sys up w/ gcc 3.3.... i'll try to get to it sometime.. things are rather hectic over here, and my computer became quite unstable these last 2 days for some reason (no, i don't think its gcc 3.3: _no_ application crashes; only total system freezes...)
anywho... i'll try to post it sometime. =] i haven't forgotten.

Removing -ffast-math from CFLAGS will solve the problem.

Well, I am getting hit with the cluestick...
My problem with broken static apps had nothing to do with gcc 3.3, and has more to do with compiling glibc and gcc itself with the ProPolice stack protection.
I am using gcc-3.3 with ProPolice stack-smash protection now, but I filter the -fstack-protector flag from glibc and gcc. I am posting nonsense related to this at https://bugs.gentoo.org/show_bug.cgi?id=25299 |

Dont know why Im getting this, Im rebuildning the system from a knoppix cd. No bigger problemes until the ttkfdir problem. Is this package absolutely needed or can I block it and do emerge --resume, to resume my broken emerge -e ??

This error is in your standard lib includes, not in ttmkfdir. I don't know why you would be having this... i'll try to look into it further and post here, just clarifying that this isn't ttmkfdir related.

someone mentioned looking into it further...any news? (I'm having the same problem...)
