Aaarrrggghhh... Another hardware component irritating me... Ok.. I need some help here... This is what the README file says about the install (the file can be found here: http://www.lexmark.com/US/products/i...nux/index.html)


What do you think I should do seeing as though I'm using Debian?


EDIT: The README file also mentions the requirement of Kernel Development Libraries.. Now I tried looking this up in Aptitude.. But nothing.. what is the package name for the Kernel Development Libraries?

At least you need the header files that were used to compile your kernel. If you unpack a kernel source they are in subdirectory include/linux. That's what all the INCLUDE= stuff is there for. If you are using a debian kernel there should be a matching package with these files (package kernel-headers-<more stuff dep. on your kernel>). Install this and point the 'INCLUDE=' option at it as in the examples you quoted.

If you compiled your own kernel - well, you know where the source code is

I'm not sure either what they mean by kernel development libraries. Can't hurt to just run 'make' and find out what's missing that way.

Thanks... But what if I used a precompiled kernel with the help of apt? Then I don't really have the source.. .or do I?

There should be a matching package called kernel-headers-<something>, where the <something> matches the kernel version. You should apt-get install it and check where it dumps its files. That will give you the 'INCLUDE' directory to use with 'make'.

Ok.. I've compiled my own kernel.. and I tried typing the following (I also included the error):

I've tried with include/linux instead.. but that just gives me even more errors!

It appears that the code you are trying to compile is specific to a 2.4 kernel. The missing file modversions.h is present in the 2.4 kernel code but not the 2.6 code.
