[linux-dvb] configuration of Cinergy DT USB XS

[D. Webert]

Using the guide 
at 'http://www.linuxtv.org/wiki/index.php/How_to_install_DVB_device_drivers ' 
to compile the v4l-dvb source code with 'make'  I get the following error 
message:
make -C /home/v4l-dvb/v4l
make[1]: Entering directory `/home/v4l-dvb/v4l'

Is that a known item or did I something wrong?
