The czap utility (dvb-apps/util/szap/czap.c) cannot scan the channel configuration file when compiled on Fedora 12 with gcc-4.4.2. The czap output is: [klaas@myth2 szap]$ ./czap -c ~/.czap/ziggo-channels.conf Cartoon using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' reading channels from file '/local/klaas/.czap/ziggo-channels.conf' 1 Cartoon:356000000:INVERSION_AUTO:6875000:FEC_NONE:QAM_64:1660:1621 ERROR: cannot parse service data Problem is tha the "sscanf" function uses the "%a[^:]" format specifier. According to "man sscanf" you need to define _GNU_SOURCE if you want this to work because it is a gnu-only extension. Adding a first line "#define _GNU_SOURCE" to czap.c and recompiling solves the problem.
