I upgraded to Core 2, but this has caused an issue with rebuilding drivers. At first it complained that there were no header files. It told me that I had to run make on the kernel. This of course, created the version.h file with "custom". I cleared that and now I get the following error. Using compiler "/usr/bin/gcc". Use environment variable CC to override. Argument "gcc (GCC) 3" isn't numeric in numeric ge (>=) at /usr/bin/vmware-config.pl line 1493, <STDIN> line 1. What is the location of the directory of C header files that match your running kernel? [/usr/src/linux/include] The kernel defined by this directory of header files does not have the same address space size as your running kernel. In the past with all version going back to RH7.3, I have only had to install the kernel source to build drivers. This is the first time that I have had to do anything with them. -- Edward M.
