How do I activate emulation in the Coddeblocks Arduino IDE I stumbled upon this question here, so I tried the Codeblocks alternative. After opening an Arduino Project, and leaving all options to default, I ran the Arduino version of the Hello World. A popup opened that requests a serial port to move on. What error did I do? 

If more details are needed I'll answer the comments. Thanks in advance!
I have not done extensive testing with the simulator but here is what you do open code blocks start a new project. Then under the target choose simulator. See the picture for details. 

I just tested it out for the simple program but this looks pretty cool.
