Read the README first, it will tell you exactly what steps to take before compiling KWebcam.
In order to compile and install Kwebcam on your system, type the following in the base directory of the Kwebcam distribution:
% ./configure
% make
% make install
Since Kwebcam uses
autoconfyou should have not trouble compiling it. Should you run into problems please report them to the the author at Troy Ogden
