I tried to compile the ftape-4.xx driver for kernels
2.2.x and I had to do some hacking myself.

I only have a small problem now:

First I do:

/sbin/depmod -a

This should update the file /lib/modules/2.2.5-15/modules.dep

This file contains the lines:

/lib/modules/2.2.5-15/misc/ftape.o:
/lib/modules/2.2.5-15/misc/zftape.o: /lib/modules/2.2.5-15/misc/ftape.o

So zftape.o depends on ftape.o.

Now I try to load these two modules:

/sbin/insmod ftape.o
/sbin/insmod zftape.o

Loading the first module works fine. But loading the second it complains
about "unresolvved symbols". However, these symbolds ARE resolved since
these are present in ftape.o.

Anyone can help? What am I doing wrong when loading the modules?

Using insmod. Try 'modprobe zftape' and see if all your problems go
away. Since there's a tool for loading dependent modules use it.

Note: if you still get missing symbols, they are really missing, or you
have the dependancies wrong.

| I tried using modprobe but I still get the missing symbols. I checked

Did you check that (a) the object contains the symbols (not dropped for
any ifdef or whatever), and (b) that the copy in
/lib/modules/{version}/misc/ftape.o is the same? Did a 'make
modules_install' get skipped, for example?

Oh, and was the kernel rebuilt when the module was added, and is it
being used for boot? I would be tempted to make everything over starting
with dep and clean, just to be sure everything is loaded. And if you
boot with lilo, you rerun that, of course.

I still think some part doesn't know the other has been changed, but I
don't have a great way to say which one.
