Ummm, When I installed VMware via tgz (same thing happens with rpm) When it gets to the part where it looks for custom vmmon modules, it says it has to custom compile my module, when I point it to my includes directory (/usr/src/linux-2.4.18-0.4/include) it tells me that the kernel found is multiprocessor while the running kernel is uniprocessor..... Here are my exact commands...

Code:
Trying to find a suitable vmmon module for your running kernel.

None of VMware Workstation's pre-built vmmon modules is suitable for your 
running kernel.  Do you want this script to try to build the vmmon module for 
your system (you need to have a C compiler installed on your system)? [yes] 

What is the location of the directory of C header files that match your running kernel? [/usr/src/linux/include] /usr/src/linux-2.4.18-0.4/include

The kernel defined by this directory of header files is multiprocessor, while 
your running kernel is uniprocessor.
Any help is appreciated...
