Modules of the kernel

[stefano]

Hi, 

I'm trying to install the Pavilion webcam driver but the make command to
compile the module gets an error.

:~/Desktop/r5u870-0.10.0$ sudo make
make -C /lib/modules/2.6.22-14-rt/build
M=/home/stefano/Desktop/r5u870-0.10.0 V=0 modules
make: *** /lib/modules/2.6.22-14-rt/build: Nessun file o directory.
Stop.
make: *** [all] Error 2

I've installed both build-essentials and linux-source packages.

Is there anyone who can help me?

Stefano
