Re: compile and link comedi question

Hi All,
 
Thanks for the help from Emmanuel and Klaas, I made some progress on this linking thing. I still have one problem: the linking can find other comedi functions except "comedi_do_insnlist". I did a nm on libkcomedilxrt.a. Sure enough that the function is not in it. The libkcomedilxrt.a came with rtai 3.1 test2. Any idea how to solve this? I guess I can call comedi_do_insn a few times to replace the insnlist. :-D
 
Thanks.
 
Everett
