None of the pre-built vmmon modules for VMware Workstation is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] Using compiler "/usr/bin/gcc". Use environment variable CC to override. Your kernel was built with "gcc" version "4.0.4", while you are trying to use "/usr/bin/gcc" version "3.3.6". This configuration is not supported and VMware Workstation cannot work in such configuration. Please either recompile your kernel with "/usr/bin/gcc" version "3.3.6", or restart /usr/bin/vmware-config.pl with CC environment variable pointing to the "gcc" version "4.0.4".
