Comedi demo and tut program problems

Hi to all,
I'm istalling comedi-0.7.72 whit the comedi-0.7.72 for use a NI-DAQ 6220
card whit the RTAI 3.4 system.

I have install the rt system and the comedi lybraries whit no problems
(apparently).
I'm successful execute the demo/info program, this is the output :

overall info:
  version code: 0x000749
  driver name: ni_pcimio

    start: now|ext|int
    scan_begin: timer|ext
    convert: timer|ext
    scan_end: count
    stop: none|count

  number of channels: 1
  max data value: 255
  ranges:
    all chans: [0,1]
  command:

subdevice 10:
  type: 5 (digital I/O)
  number of channels: 7
  max data value: 1
  ranges:
    all chans: [0,1]
  command:
    not supported

but if I try to execute the "demo/tut1 0 0"  program it's print -1 value.
any idea?


I try to compile the second Comedi program describe in the comedi
reference guide, but the compile return this error :
dereferencing pointer to incomplete type, related to
"comedi_data_read(cf->fd,subdev,chan,range,aref,&data);" code line.

It's generate from the some problem?

thanks,
D.
