Hi,
I have made a fix for the change in comedilib. The fix is as follows,
the struct cmd in comedilib has been extended with the variable
chanlist_len (in version 0.8) and it is this variable that is missing in
the calls to "comedi_get_cmd_generic_timed" made in the files
gr-comedi/src/comedi_source_s.cc and gr-comedi/src/comedi_sink_s.cc.
The current call in comedi_source_s.cc is:
ret =
comedi_get_cmd_generic_timed(d_dev,d_subdevice,&cmd,(unsigned
int)(1e9/sampling_freq));
fix
ret =
comedi_get_cmd_generic_timed(d_dev,d_subdevice,&cmd,cmd.chanlist_len,(un
signed int)(1e9/sampling_freq));
and the current call in comedi_sink_s.cc is
ret =
comedi_get_cmd_generic_timed(d_dev,d_subdevice,&cmd,(unsigned
int)(1e9/sampling_freq));
fix
ret =
comedi_get_cmd_generic_timed(d_dev,d_subdevice,&cmd,cmd.chanlist_len,(un
signed int)(1e9/sampling_freq));

It appears that an incompatible API change between comedilib 0.7 and
0.8 breaks the gr-comedi component.
Please file a bug in the GNU Radio tracker. What system are you running
that now has 0.8 installed?
gr-comedi was originally written and last updated in 2005, and doesn't
currently have a maintainer. Would you be willing to work on a fix,
with some email guidance from myself and Eric?
