GCC hell

Hi all...

I have been running Gentoo for a couple of months now, and I have consistent stability problems with Java and Eclipse. I really think the problem is GCC 3.2.2 related, so I tried to recompile the entire system with GCC 2.95.3-r8. (BTW: my GCC 3.2.2 compile flags were extremely conservative, namely -O -march=pentium3 -pipe). This didn't exactly work as expected. If I mask 3.2.2 then I get dependency errors saying that >=3.2 is required.

Is there any way that I can get my system up and running on 2.95.3 all the way? Or are there hard dependencies on 3.2?

I really need a stable system, I moved off FreeBSD (very stable) due to insufficient Java support, to Debian in which everything worked except for package management (it eventually trashed my system with incompatible binary versions of libs and packages). I *REALLY* love Gentoo, but I *NEED* stability, my job depends on it.

Any tips are most welcome....

Ehmmm...
Use a Gentoo 1.2 LiveCD is the only thing I can think of.

Pop in CD, boot, mount old filesystem, chroot, and try to use the compiler from the CD, and unmerge evertyhing, and then emerge everything again.
Or you can reinstall Gentoo, using 1.2, but I can only recommend that if you can safely backup your /home and aren't worried about losing your entire config. (the first option might also seriously mess up your config, but there's a big chance that most of the things come out alright)

You need to have both installed if you want to use 2.95.3 with a 1.4-profile system.

Make sure 3.2.2 is installed. Then:

emerge =gcc-2.95.3-r8

gcc-config i686-pc-linux-gnu-2.95.3

And you'll be using 2.95.3.

Hi,

Downgrading the libc version to 2.2.5 just broke my system, so I'll be having to do a complete reinstall. The default glibc depends on gcc version 3.2.2. I want nothing to do with this gcc version and a complete system running on gcc 2.95.3. Just installing 2.95.3 additionally doesn't really help, because when installing eclipse I don't need to COMPILE anything, and just running it doesn't work. I did try to compile pretty much everything with 2.95.3 but after that mozilla, java, etc., all crashed with a segfault in libfreetype.so.6.
Maybe compiling the sun-j2sdk would work with 2.95.3 (not crashing in hotspot with a segfault while compiling under 3.2.2), but then that would mean I would have to compile mozilla with 2.95.3 as well, including all its dependencies. The question is, where do the dependencies stop? I prefer NOT to mix versions, and just use 2.95.3 for everything. Is this possible on Gentoo 1.4 or do I need to use a different Linux distribution?

Oh, and if you install 1.2, you'll find that portage won't work until you read:

/usr/portage/sys-apps/portage/files/README.RESCUE
