Error Building the V4L-DVB drivers from source

Hi,
My name is Alex and I recently tried to install the v4l drivers on my machine. Environment:

    Ubuntu release 10.04(lucid)
    Kernel Linux 2.6.32-24-generic
    GNOME 2.30.2

I followed the steps given on the wiki at:
http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

using Mercurial to get the source code

When I get to the "Building/Compiling the Modules" stage where I need to call "make" in the /v4l-dvb/ folder, the whole process begins and a lot of files are generated but after a few
minutes I get this:

The first error seems to be because it cannot find dma.h

Is this a bug or am I doing something wrong?

Thank you,
Alex

Ubuntu has a bug in their packaging of the kernel headers, which results in the firedtv driver not building. Just edit "v4l/.config" and change the line that says "firedtv=m" to "firedtv=n"

Cheers,

Devin
