VMWare: “Unable to build the vmnet module”

Filed under: General Linux,Linux Software — at 10:49 am on Monday, July 21, 2008

If you run into the following problem:

VMware Server is installed, but it has not been (correctly) configured
for the running kernel. To (re-)configure it, invoke the
following command: /usr/local/bin/

and then try to issue the command and get something similar to the following:

/tmp/vmware-config1/vmnet-only/bridge.c: In function ‘VNetBridgeUp’:
/tmp/vmware-config1/vmnet-only/bridge.c:949: error: implicit declaration of function ‘sock_valbool_flag’
make[2]: *** [/tmp/vmware-config1/vmnet-only/bridge.o] Error 1
make[1]: *** [_module_/tmp/vmware-config1/vmnet-only] Error 2
make[1]: Leaving directory `/usr/src/kernels/'
make: *** [vmnet.ko] Error 2
make: Leaving directory `/tmp/vmware-config1/vmnet-only'
Unable to build the vmnet module.

Then try to use the VMWare any patch from:
I had used the patch before to get my VMWare Server up and running but did not realize that you had to use the patch after kernel upgrade or your VMWare server will no longer work.

Who knew?
