edit kernel Makefile and append -fno-tree-scev-cprop to the KBUILD_CFLAGS

I was just wondering if anyone else was having issues building a recent custom kernel. I find that it fails on the make command. Here is the output I get:

I have tried kernel 2.6.24 and 2.6.24.4 on two different machines with two different cpu's (one intel dual core and one AMD 64 bit). I've tried using my previous config (make oldconfig) and also tried without it. I even ran make clean && make mrproper on the new extracted kernel directory before attempting to build it. Usually upgrading a kernel is very routine for me, but this time it isn't working. All kernel sources were downloaded from kernel.org as usual for me.

Any ideas would be appreciated.

Thanks,

Linux 2.6.24 is broken with GCC 4.3. Either wait for the next release (which will most likely include a fix) or see this bugreport: http://bugs.archlinux.org/task/9801 it includes a link to a patch to compile linux with GCC 4.3. Glenn
