Hello, I'm trying to get vdr-1.4.0 built on Ubuntu. I'm using the source from the apt repository (apt-get source vdr). I'm getting this: root@media:~/vdr-1.4.0# make g++ -fPIC -g -O2 -Wall -Woverloaded-virtual -c -DREMOTE_KBD -DLIRC_DEVICE=\"/dev/lircd\" -DRCU_DEVICE=\"/dev/ttyS1\" -D_GNU_SOURCE -DVIDEODIR=\"/video\" -DPLUGINDIR=\"./PLUGINS/lib\" thread.c thread.c:319: error: 'gettid' has not been declared thread.c:321: error: expected constructor, destructor, or type conversion before 'tThreadId' make: *** [thread.o] Error 1 root@media:~/vdr-1.4.0# If I comment out the line: _syscall0(pid_t, gettid) And change the gettid() call just below it into: return syscall(224); Then it builds, and seems to work fine. Clearly I'm just missing a gettid definition, but does anyone know which Debian/Ubuntu package (they're basically the same) it's in? I have linux-kernel-headers 2.6.17-5.16 installed, I'm not sure where else to look. thanks! -- Chris
