Problems compiling programs in Comedi

Hi all,

I'm trying to compile a comedi program using the command:

gcc usergrab4.c -lcomedi -o usergrab4

The compiler returns with:

/tmp/cckKQIrn.o: In function `main':
/tmp/cckKQIrn.o(.text+0x12f): undefined reference to `filename'
/tmp/cckKQIrn.o(.text+0x14a): undefined reference to `filename'
/tmp/cckKQIrn.o(.text+0x205): undefined reference to `aref'
/tmp/cckKQIrn.o(.text+0x214): undefined reference to `range'
/tmp/cckKQIrn.o(.text+0x222): undefined reference to `channel'
/tmp/cckKQIrn.o: In function `do_cmd':
/tmp/cckKQIrn.o(.text+0x358): undefined reference to `dump_cmd'
/tmp/cckKQIrn.o(.text+0x3c2): undefined reference to `dump_cmd'
/tmp/cckKQIrn.o: In function `prepare_cmd':
/tmp/cckKQIrn.o(.text+0x7ac): undefined reference to `subdevice'
collect2: ld returned 1 exit status

Any idea how to resolve these errors?  Similar errors occur when I try to
compile, for example, select.c out of /comedilib-0.7.21/demo/.

Thanks a whole bunch!

Alex
