If you get this error during the Vmware module compilation:
Unable to make a vsock module that can be loaded in the running kernel:insmod: error inserting ‘/tmp/vmware-config1/vsock.o’: -1 Unknown symbol in module
What you need to do is the following:
untar vmci.tar (in /usr/lib/vmware/modules/source)build the module with ‘make’untar vsock.tar and copy the “Modules.symvers” file resulting from the previous compilation into the “vsock-only” directory. Rebuild the vsock.tar file and run “vmware-config.pl”.
Speaking in bash language:
cd /usr/lib/vmware/modules/source/tar xvfp vmci.tartar xvfp vsock.tar cd vmci-only/makecp -av Module.symvers ../vsock-only/cd ..tar -f vsock.tar -cv vsock-only/vmware-config.pl
Now it should compile just fine.Thanks to Javier, I got this solution from http://communities.vmware.com/thread/208316
