I tried to check if I could replicate the issue (without Eigen) and I was not able to do it. I used a simple example I previously verified to work when ran from Linux.
Now, I would like to check if in fact the issue is related to Eigen, for that I will have to ask you to explain the steps you took to add this library to Eclipse and, ideally, to share your code (because there's a possibility that the issue might be related to it).
Thank you very much for your reply. I have figured out the problem. It is because I wrote the class by creating a separate header file and cpp file instead of selecting add a new class from eclipse. It seems to cause eclipse to fail to recognize the main file.
