Going by the links on that page you can download the kernel module (driver) for the webcam here
depending on your kernel version. You can figure out your kernel version by entering
Then read the READ_AND_INSTALL document for how to compile. Here's a relevant section from that file for the driver later than 2.6.11 kernel.
The driver module can be built without modifying your kernel source tree.
Before trying to compile the driver, ensure that you've configured your
kernel, and updated the dependencies:
'make [config|menuconfig|xconfig]; make dep'.
Make sure, when compiling the driver, you use the same version of compiler as
was used to compile your kernel. Not doing so can create incompatible binaries.
goes to gspcav1 directory and run:
if all goes right the module is compiled and load in memory
if not, errors messages can be found in kgspca.err You should post this file to the maintainer
or in the sourceforge project bugs report. <http://sourceforge.net/projects/spca50x/>.
Basically you change directory (cd) into the source tree and then configure it and compile.
Since you're on Ubuntu you'll need to install a few build packages before you're able to compile the module/software.
sudo apt-get install build-essential autoconf make
You should read all of the included documentation such as READ_AND_INSTALL, license, and changelog before modifying your system with the kernel module. If you run into problems where it's complaining about kernel headers you'll need to install the headers package for your installed kernel version.
