I know, that one cannot use comedi.h and comedilib.h in realtime code, as they are userspace files. Instead one mus call kcomedilib. I searched and found a file /comedi/include/linux/comedilib.h which seems to be the real-time library. Is that correct? > > What I did was to include this file in my realtime code and got an error message, that <linux/comedi.h> did not exist. Changing paths to an existing comedi.h worked for compilation but when I tried to insert my realtime/comedi module I got unresolved symbols comedi_open and comedi_writedata. > > I would be very thankful, if one of you would be so kind to tell me, how I can actually use comedi fuctions in rtlinux. I would very muchg appreciate your help! Maybe you could tell me what I have to change in my rtlinux code and my makefile (attached to this mail). You need to insmod kcomedilib.o. If this module doesn't exist, you need to enable it when building comedi against your RTLinux kernel. -Calin
