Hi All. Just upgraded from gcc-4.0.2 to gcc-4.1.0
All apps compiled okay (Linux-2.15/Gimp/Blender3D/Glibc2.3.6) however the new bzImage I have from GCC 4.1.0 wont boot. it just loads from lilo then halts.
I used the exact same config as with the old bzImage to make sure.

Anyone else have this problem?

It is not required to recompile everything just because you've upgraded gcc.

Does the old bzimage still boot?

Which kernel(s) are these?

"Home Brew" does not appear in distrowatch. While there are a lot of "homebrew" linuxes around I cannot seem to find anything resembling a distro. Could you point me to the maintainer site, thank you.

(Or do you mean that your distro is "home brewed", as in, you made it yourself from scratch? In which case, this is LFS.)

Wow, you've had more success at that than I have.

Since gcc-4.1.0 is so new, chances are the Linux kernel can't be reliably compiled with it.

I would search Linux kernel mailing lists for compilation problems using gcc-4.1.0.

Peace...

Just to clear some stuff up.

Im trying to compile linux 2.6.15.4

Yep. re-compiling isnt required, but I like to recompile base parts of the system if a new GCC makes more optimal code.
Eg- gcc-4.0.x Blender3D binaries tested 12% faster for raytracing then gcc-3.x,
on similar tests gcc-4.1 binaries are 5% faster.

Linux dosent use the env CFLAGS so Im fairly sure Linux source just needs to be updated to work with the latest GCC.

There are possibly some bugs in GCC also, the flags I was using with 4.0.2 make a binary that segfaulted Blender3D with 4.1.0, just removed some of the flags like -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-cse-after-loop -frerun-loop-opt -falign-functions=4 -maccumulate-outgoing-args -fprefetch-loop-arrays.
