Link error - prototype not found: SetEasyIOMultitaskingMode()

[Danimal]

I cannot compile my application. I receive the following link error:
Prototype not found: SetEasyIOMultitaskingMode ()

How, or where, do I get the file that has the prototype for this function?

Thanks,
Dan

That function is part of our Easy I/O library for DAQ. That library installs with the NI-DAQ software. It sounds like you need to reinstall NI-DAQ and install CVI support to update that library. If you already have NI-DAQ installed, go to Start->Programs->National Instruments->NI-DAQ->NI-DAQ Setup. Go through the setup process and make sure LabWindows/CVI support is installed and that it is installing to the correct directory (your cvi main directory.

Chris,

Thanks for the reply, but it did not work. I had previously installed 6.8.1 I re-installed the 6.9.2 driver from the CD-ROM and rebooted, but I still get the same link error (Undefined symbol: SetEasyIOMultitaskingMode).

I'll give you more info:

I am modifying an application that runs on a PC (running Windows2000) which tests a separate Linux machine. Someone in my team is running NT and can compile it without problem. I included a Word doc with a picture that shows what I have selected when installing from the NiDAQ CD-ROM. I think the correct file is easio.h and I have searched my whole hard drive but cannot find it.

Measurement Studio is installed in C:\Measurement Studio and my application is in a separate directory (C:\work_
projects). I wouldn't expect that to be a problem.

Any help is appreciated,
Dan

That should have installed the files. I'm not sure why it isn't. You should give our support engineers a call and let them try and fix it or if they can't they can e-mail you the files. To generate a service request and call us go to http://www.ni.com/ask.
