Im trying to install the alsa 0.9.4 drivers and after the ./configure step i get this message:

checking for directory with kernel source... /lib/modules/2.4.20/build
checking for kernel version... The file /lib/modules/2.4.20/build/include/linux/version.h does not exist.
Please, install the package with full kernel sources for your distribution
or use --with-kernel=dir option to specify another directory with kernel
sources (default is /usr/src/linux).

Please, run the configure script as first...

where kernel sources are stored by slackware 9

If you have the one-cd version of Slackware 9.0 - then you have no kernel sources
You better go to http://www.slackware.com/getslack/, look for a close mirror, d/l a kernel source (.tgz), and install it using installpkg.

Kernel source wasn't included with slack 9, they couldn't fit it in. It's highly recomended you install it tho. Go to a mirror of slackware.org (through slackware.org, get slack) and then in slackware9/slackware/k or thereabouts, find the source tgz, dl and install with installpkg.
package kdei was also left out. Think that's international support for kde.

Thanks guys
