--------------
Prerequisites

You need a recent kernel at least 2.6.6 or 2.4.26 with source. Under Red Hat or Mandrake, the sources can be installed using the package kernel-source<kernel-version>.rpm command. Under Ubuntu use the sudo apt-get install linux-headers-`uname -r` command. Make sure there is a link to the kernel source from the modules directory. /lib/modules/VERSION/build should be a link to the kernel source, where VERSION is the version of the kernel you are running. If there is no link, you'll get an error at the make install step. To create a link, assuming the kernel sources are present, use the command


ln -s /usr/src/linux-<kernel-version> /lib/modules/VERSION/build

Under Ubuntu, you also need the build-essential package, use the sudo apt-get install build-essential command.

Make sure you have started compiling the kernel sources, so needed header files are present. Some vendors ship ndiswrapper in their distributions. Either use it or make sure you remove it before installing ndiswrapper by yourself. Make sure you have the Wireless Tools installed. Again, there is a package that comes along with Red Hat and Mandrake distributions. If you are using Debian you can install the wireless-tools package from the mirror, here.
