problems with easing example

beginners
#1

Hi, I am trying to build the easing example from http://jesusgollonet.com/openFrameworks/cppPennerEasing.zip, but I am getting errors from both files particle.h and .cpp.

I think it is better if I attach an image, I guess it is an issue about ofAddons.h, but I haven’t found the way to make it work. I have tried putting ofAddons.h on the addons folder and on the src folder, but the I get the same errors

Can you tell me what am I missing?, thanks.

Ricardo.

you need to add ofAddons.h to your project. you can right click the project name and click add files and add it.

#3

Actually, ofAddons.h is not used anymore, you need to add the ofxVectorMath addon in order to compile properly

#4

Hi, I tried adding ofxVectorMath.h and including it in particle.h but I get the same errors, the same happens if I include it in main.cpp, I don´t know where to include it to compile successfully.

Any ideas of what am I doing wrong?

Thanks
