bootstrap with gcc 3.2

I'd like to bootstrap and install my entire system with gcc 3.2 pre. I edited the mask file so i can emerge gcc 3.2 pre. when i run emerge -p gcc it outputs 3.2 pre. But i would like to bootstap with it, when i run that, it says "Using >=gcc-3.1-r6" which i'm taking to mean that gcc 3.1-r6 will be installed. How do i get 3.2 installed during bootstrap

I'm pretty sure that durring bootstrapping it will compile gcc twice, and I believe that the second time it does it will use gcc 3.2

yep, you were right. When gcc is rebuilt later in the bootstrap it is using gcc 3.2. thanks

My gcc3.2 (snapshot 28/7/2002) bootstrap broke with glibc. Not that smart :-(

I'll try again once gcc 3.2 has been released officially. What are your experiences with gcc3.2 ?

I bootstrapped my system with 3.1.1, and then emerged gcc3.2-pre and did a emerge -e world, and everything seems to be going fine for me....

What flags did you use?
as some packages (xfree-4.2.0) won't compile with -mmmx and -m3dnow for example.

I used:

CFLAGS="-O3 -mcpu=pentium3 -march=i686 -pipe -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4"

but to compile XFree i had to drop -fforce-addr

I bootstrapped with whatever was included with the 1.3b stage1 tarball, and edited portage to download/compile gcc 3.2_pre. The first time it failed, and the only thing I changed in make.conf was march=athlon-xp. I wiped it and tried again, leaving the make.conf alone (except for uncommenting my corresponding flags). Leaving it at march=i686 led everything to work.

The question is though, now that I have a working system (if you can even call it since only stage1 is done), do I chance that gcc3.2 will be able to compile gcc3.2 with the athlon-xp flag and reinstall itself? ... hmmm...

I used -march=athlon-xp -msse -m3dnow -mfpmath=sse -mmmx -O3 -pipe and everything (including X and KDE) compiled fine.

I booted from a 1.2 disc and emerged gcc (3.2pre) with -march=i486 -O3 -pipe before bootstrapping with the above opmisations

I just tried to emerge gcc-3.2-pre, but file not found.

Is is gcc-3.2-pre or gcc3.2-pre or what ? I couldn't see it in the package.mask anywhere either, if it was supposed to be listed there.

This was from doing an emerge rsync clean about 5 minutes ago, using the stage1-ix86-1.3b-r1.tbz2

I had the system compiling nicely with 3.1.1 but thought I would give 3.2 a go.

My system has now been installed from scratch using GCC3.2_pre, and while I chickened out a bit on some of the more "fancy" optimizations. (-march=athlon-tbird -O2 for bootstrap added -fomit-frame-pointer for the rest) my system is now fully operational and I'm quite happy with it so far.

Right now I'm having some fun compiling KDE CVS.

But the succeslist so far includes:

KDE3.0.2, Xfree86 4.2.0 (filtered mmx and 3dnow), KDevelop, KOffice, DVDrip, VIM and of course Frozen Bubble. All dependencies forfilled.
