for config question

Dear comedi engineers,

I am Luo xiang, a research fellow of  Yokohama National University, Japan.
we now try to use force sensor on our biped robot (real-time control). Our
robot configuration: Force sensor OMEGA160-R-10-2-N and ATI pci-6034E
multifunction card, OS: Debian linux 3.0+ Rtlinux3.1(patched in kernel
2.2.19). in our lilo list, there are:
                 linux
                 rtlinux
                 wondows

following directories are existed:
              /lib/modules# ls
              2.2.19-rtl
              2.2.20-idepci

               /usr/src/rtlinux# ls
               linux
               rtlinux-3.1

when start computer, i choose rtlinux to install comedi. install directory
is
              /usr/local/comedi-0.66# make config
it hints:
              Enter location of linux source tree [/lib/module/2.2.19-rtl]:
and i input: "/usr/src/rtlinux/linux"
it seem no error.
then it hints:
.......
            Enter location of RTL source tree [/usr/src/rtl]:
and i input:"/usr/src/rtlinux/rtlinux-3.1"
it hints:
            #using defaults found in .config
           *Comedi Feature

then i choose
Rt support, kernel comedilib and ni_pcimio
then:
                /usr/local/comedi-0.7.66# make
it appers a list of error:
mainly is multiple definition of 'xxx', such as:
                 proc.o(.rodata a+0x0): multiple definition of
'comedi_debug'

I don't know where is wrong. I spend several in this problem. How should i
do?

Many thanks in advance.

sincerely,
Luo Xiang
