Hi Steve,

First thing you need to do is check if you have the kernel sources
installed.  Do a 'uname -r' at the command line, and it should give you
back something like '2.4.22-10mdk'.

Then type 'rpm -qa |grep kernel-source'.  This should return something
like "kernel-source-2.4.22-10mdk".  The 2.4.22-10mdk is the version of
the kernel source, this should match what is returned by the 'uname -r'
command above.

If this is okay, then you have the kernel source installed.  If not, as
root, type 'urpmi kernel-source' and Mandrake will prompt you for the
relevant CD and install it.

Once the kernel-source package is installed, also as root type 'ln -s
/lib/modules/2.4.22-10mdk/build /usr/src/linux-2.4.22-10mdk'
(substituting the correct version numbers of course, if yours are
different - they may be if you have installed the updates).

Then go back and attempt to rebuild your winmodem drivers, it should
hopefully work now.  Incidentally, to create an RPM from the package,
you will need a .spec file which should be included in the driver
package you have.

To create the RPM, the following may work.  This should be done as root
unless you have 'sudo' installed, which is a good idea (if not, 'urpmi
sudo', 'man sudo', and 'man sudoers' should help you out.

Firstly, copy the archive into /usr/src/RPM/SOURCES/.  Then, in your
home directory or wherever you choose to work, untar it and cd into the
directory new directory, then run 'rpmbuild -ba <spec file>', where
<spec file> is the name of the file ending in .spec, or .spec.in
supplied in this directory.

Hopefully others will correct any mistakes I've made here, or possibly
point out more efficient ways of accomplishing this, as it's 1am here
and I've just got back from the pub :)

Regards,

Ruairí
