Hi Vasileios,
I can't belive what I saw ;-))))))))))))))))))
When compiling kernel-modules which are not part of your
current kernel sources, you should make sure, that the make-command
for these modules will access the correct include/linux directory.
In your case the problem is the temporary directory...
It's exactly the same stuff like the SMP problem, you remember?
So what to do?
If you try out a new kernel, install the sources in parallel to your exisiting
sources, for example you already have 2.2.5 so your /usr/src directory
will look like this:
/usr/src/linux-2.2.5
/usr/src/linux --> linux-2.2.5
you like now kernel 2.4, so copy this one to
/usr/src/linux-2.4
and update the link, so you have the following configuration:
usr/src/linux-2.2.5
/usr/src/linux-2.4
/usr/src/linux --> linux-2.4
When you now recompile the pt_drv module, it will access
the correct linux/include directory and you'll have now problems
with the version stuff anymore.
By using this procedure, you can have quite a lot of kernels in parallel
without any problems.
Hope this helps
