Kernel compile aborts in make bzImage

Disclaimer:  *****
I deleted your initial message, so I'm not sure what you are trying to do
in the first place.
If you are trying to build the kernel that came with the 2.2  release, the
problem
may be that you need to copy a config file from the /usr/src/linux/configs
directory
into /usr/src/linux as .config and then do the build.  Take the one that
applies to
your machine.

If you've done that and you are just building a kernel with some different
options
or modules, then the following applies.

End Disclaimer ****

It looks like you need to add some more options to your kernel, as there
are
functions being called that are not linked in.

For sk_attach_filter,
I went to /usr/src/linux/net and did

grep -r sk_attach_filter *

which returned the following

core/filter.c: *        sk_attach_filter - attach a socket filter
core/filter.c:int sk_attach_filter(struct sock_fprog *fprog, struct sock
*sk)
core/sock.c:                            ret = sk_attach_filter(&fprog, sk);
Binary file core/sock.o matches
Binary file core/filter.o matches
Binary file core/core.o matches
Binary file network.o matches

then I went into the core subdirectory and looked at Makefile to see what
includes
filter.o,  the file which would define that routine and see:

obj-$(CONFIG_FILTER) += filter.o

 meaning that if CONFIG_FILTER is set, then filter.o will get included in
the link.

So, now you would do make menuconfig or make xconfig and set CONFIG_FILTER.

It may be helpful to also look in the
directory tree working backwards from core to find a Config.in which
contains CONFIG_FILTER, as it will tell you the text to look for in
configuring
that parameter.  In this case it's /usr/src/linux/net/Config.in and the
line is

bool 'Socket Filtering'  CONFIG_FILTER

Thus in "make menuconfig", when you enable Socket Filtering, you will
get filter.o included and your undefined for sk_attach_filter will go away.

The problem is that sometimes the kernel has dependencies which
are not all protected and these "mismatches" occur.

Good Luck!

Subject:  Re: Kernel compile aborts in make bzImage

Not solved. After reinstalling the kernel sources and
using make vmlinux, the compile now hangs
systematically with several lines of the form:
In function 'sock_setsockopt'
net/network.o(...stuff...): undefined reference to
....
sk_attach_filter
kmap_high
kunmap_high

and several more functions and undefined references.

Looks like a linker error. How come? What could I
reinstall/correct to resolve these?
