Hello, 

I just managed to install v4l on Ubuntu Hardy


I downloaded
libv4l-0.5.98.tar.gz from this URL http://people.atrpms.net/~hdegoede/ 

tar xvzf libv4l-0.5.98.tar.gz
make

then I copied the libs to /usr/local/lib

and redefined the variable

export LD_PRELOAD=/usr/local/lib/libv4l.0.5.98/libv4l1/v4l1compat.so

and for the next session
echo "export LD_PRELOAD=/usr/local/lib/libv4l1/v4l1compat.so" >> ~/.bashrc

Works fine with a Logitech Quickcam Communicate STX

++
OH
