I'm running Vmware ESX 4.1 and I have a development VM that I recently upgraded from Ubuntu 10.04 to 11.04. Then I tried to re-install VMware Tools and some of the modules gave me an error and would not compile. As a result I'm having problems with backing up this virtual machine now and I suspect VMware tools is the reason. I installed latest patches for VMware host, that included an update to VMware Tools (v8.3.7 build-381511) but I'm still getting the same error.

The error I'm getting is like this:

...
/tmp/vmware-root/modules/vmhgfs-only/super.c:73:4: error: unknown field \u2018clear_inode\u2019 specified in initializer
make[2]: *** [/tmp/vmware-root/modules/vmhgfs-only/super.o] Error 1

make: *** [vmhgfs.ko] Error 2
make: Leaving directory `/tmp/vmware-root/modules/vmhgfs-only'

and also this:

Any ideas?
