Can't compile vanilla sources kernel without SMP option.

[dufeu]

When I attempt to compile my kernel (either vanilla-sources-2.4.19 or 2.4.20), the compile aborts:

The warnings above the abort are typical of about 4 pages of output.

I'm running with an AMD Athlon-XP 1800+, 512meg DDR ram having used the AthlonXP stage3 tarball.

I did

# make mrproper
# cp config.bak .config
# make menuconfig (setting smp off)
# make dep && make clean bzImage modules modules_install

I have an Asus based mobo.

Help would be appreciated

I had the same problem. All I did was compile it with smp even though I have only one CPU. It's supposed add a bit of latency, but it's better than nothing. I've compile the gentoo-kernel and I THINK it worked without smp.

i've run across the same problem just now while trying to upgrade to 2.4.20 from 2.4.19 on my toshiba laptop here with an intel p4 mobile processor. i found this thread, enabled smp, and it worked. i dont really have a new solution, just thought i'd post so that you know that it is happening to more than just you.

For people having this problem, can you verify that it persists across a "make mrproper"? If you haven't done this before, search the forums for exact commands and some warnings about how not to lose your .config file.

Quick question, what does make mrproper do?
