Thanks all of you. i added Additional libraries in properties as seen in screen shot and the error are gone... now what exactly was the problem still unknown...
I also have this problem which occurs in a previously working project. Everything in the thread matches my symptom and I understand until the posted screen shot showing the "Additional Libraries". I just cannot find where this libraries exist and do not know how to add to my project to try the fix. I am using CW10.4, MQX 4.0.2. I also saw the problem with CW 10.5.
