I wish to compile a new 2.0.33 kernel with custom options. The
behaviour below appears both for 2.0.32 and for 2.0.33. I use
a clean[1] source tree downloaded from ftp.kernel.org. I have
not forgotten the symlinks from /usr/include as described in the
kernel README (and my first kernel compile was 1.0.9, so I hope
I'm immune from that sort of problem ;-))
[1] and by clean I mean (rm -rf ; tar xzf) before each test
I copy my config file to .config and run make menuconfig, exiting
immediately so that /usr/src/linux/include/linux/autoconf.h gets
made correctly.
I run make dep ; make clean ; make zImage.
The compile ends up like this:
gcc -I/usr/src/kernel-source-2.0.33/include -O2 -DSTDC_HEADERS -o piggyback piggyback.c
./xtract /usr/src/kernel-source-2.0.33/vmlinux | gzip -9 | ./piggyback > piggy.o
Non-GCC header of 'system'
Compressed size 20.
gcc -D__KERNEL__ -I/usr/src/kernel-source-2.0.33/include -traditional -c head.S
gcc -D__KERNEL__ -I/usr/src/kernel-source-2.0.33/include -O2 -DSTDC_HEADERS -c misc.c -o misc.o
ld -qmagic -Ttext 0xfe0 -o vmlinux head.o misc.o piggy.o

If I use the default config file, everything works correctly
(except that my kernel does not fit my needs, of course ;-))
I realize that my config file is a bit extreme, but I don't want
to have to put in everything just to get it to compile, so since
I'm incapable of debugging at #define level, if someone could
have a look and tell me what I should change in my config file,
it would be very kind :-)
My config file is on an extremely slow server at

(or by mail, if someone wants it that way).
