Kernel compilation problem

When i try to compile my kernels (2.4.29, 2.4.30 2.4.31) i get this error:

any idea how to fix this?
after google searching i find out that i have to downgrade - is this the only solution?

maybe you have selected some options not supported by your processor? what kind of machine do you have? can't you upgrade insdead of downgrade your kernel?

It looks like you are trying to compile kernel v. 2.4 with gcc4.0. Either use another compiler (gcc3.3 should work ok, 2.95 will definitely work) or use kernel2.6.

Why bother with 2.4 in the first place?

Try this:

Save your .config file in a nice, safe place.
make mrproper to clean everything away.
make defconfig to create a default configuration.(or, restore your original .config)
Now make xconfig and select your options again.

I would be in favor of the defconfig route because that will produce a self-consistent set of options and it seems to pay attention to what kind of CPU, etc. you have. However, if you don't want to do that, probably the area where you need to focus is in the selection of "Processor type and features."

Looking at this line in /include/linux/asm/processor.h (using "75g" in the less command, or less +75 ..., either of which put the desired line at the top of the page), I see that this particular line has something to do with SMP... does your system, in fact, have multiple processors?

Curious that you're building a kernel in /boot ... And if you do stick with 2.4, be sure to apply all of its patches!

yep, thats the problem - finally i downgraded to gcc 3.3.6 and everything is ok now. (i was searching for a workaround)

- why not build the kernel in /boot dir???
- kernel patches are cumulative or not? (i think 2.4.31 includes all patches)

- with the first chance (lack of time) i will upgrade to 2.6.12

thx for the replies
