I'm trying to build the v4l-dvb tree. I believe my build environment is setup correctly as I have installed build-essential, linux-headers and linux-source. I have extracted the source, linked to /usr/src/linux and did the whole make oldconfig thing. During the build I get errors like these: make[2]: Entering directory `/usr/src/linux-headers-2.6.31-11-generic' CC [M] /home/andrew/Technical/Source/v4l-dvb/v4l/firedtv-1394.o
