Hoo boy ... a 2.4 kernel and VMWare ...
As you figured out ( and as business_kid said ), vmware-config-tools.pl isn't seeing your kernel headers so it can't build the kernel modules for the Kernel.
Looking at the Slackware 11.0 MANIFEST, the Kernel Headers should be in 'the usual spot' ( /usr/include/linux/ ).
Code:
Package: ./d/kernel-headers-2.4.33.3-i386-1.tgz
What version of /usr/local/bin/vmware-config-tools.pl are you trying to run ?
If I recall, the Program Name used to be 'different' ... vmware-config-tools.pl may be 'too new' for the 2.4.x Kernel ???
I know I ran vmware on my Slackware 10.2 Laptop but that was long ago and the hardware is far away.
After Slackware 10.2 my next Laptop ran Slackware 12.2 which had a 2.6 Kernel -- IOW, I skipped Slackware 11.0 ...
Looking back thru my vmware directory, Slackware 11.0 would be contemporary with ( something like ) VMWare 4.5 or 5.5 ... not sure ...
I do have a copy of the vmware tools install procedure for VMWare 4.0.5 ( attached as a .pdf file ).
Maybe that will help ?
If not, sounds like a lotta googling is in order ?
Good Luck !
