kernel headers

in order to compile the driver for easycap I need the kernel headers. The install script will look for “/lib/modules/uname -r/build” directory.
uname -r tells me I’m using the kernel 3.0.28 but opkg install kernel-header will install the 3.2.18 version.

Anyway the build directory is not created under the 3.2.18 folder.

What’s the best way to get the stuff working?

a- force to install headers for 3.0.28
b- upgrade kernel to 3.2.18
