Re: Unresolved symbols in streams

Hi Andrew...

I would try a couple of things:

1) Make sure that the kernel source that you are compiling LiS
against
corresponds to the kernel that you will run with LiS (use the running
kernel first since that is the least complicated).  If necessary move
the /usr/src/linux-2.4.21 directory out of the way and reinstall the
source from the rpm.

2) Make sure that /usr/src/linux points to the directory of kernel
source above.

3) Run "make mrproper" on the kernel source directory first.  I have
found that for whatever reason the kernel source that comes "out of
the box" comes in some half-jacked state which could be the source of
this problem.  I don't know exactly what the "half-jacked" state is,
but I have had problems compiling things before if I didn't do this
step.  I can't remember exactly if the problems I had were missing
symbols like this, but this step will not hurt anything.

4) After the Mr. Proper step, run "make dep" on the kernel source.

5) Now go back to the LiS directory and run "make very-clean", then
try "make" again.  When asked if you want to use the currently
running kernel, you can try saying "yes" (the default), but make sure
and verify that if found the kernel source directory where you did
the previous steps.  It works for all 2.4 based RH versions that I
know
of.  It seems to have a bug with finding the correct kernel source
directory on SuSE 9.2 (kernel 2.6.8) however.

If that doesn't work, scream, then send a 'script' output of what you
are doing to the list so that I can try it on my machine, or at least
see what is going on better.
