Porblem adding ofxfluid to my project

Hi, I’m triing to import ofxfluid to my project but when I declare “ofxfluid fluid;” in testApp.h i have 4 errors:

Undefined symbols for architecture i386:
“vtable for ofxFluid”, referenced from:
ofxFluid::~ofxFluid() in testApp.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
“ofxFXObject::~ofxFXObject()”, referenced from:
ofxFluid::~ofxFluid() in testApp.o
“ofxFluid::ofxFluid()”, referenced from:
testApp::testApp() in main.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Someone know what is that?

might just be a case-sensitive issue?
“ofxFluid fluid;”

Not because the function appears when I write the first letters.
I think of can not find the files in the ofxfluid class because the error rate is Apple Mach-O Linker (id) Error.

I have found linker errors are sometimes due to including the example within the addon. I usually have to remove the dependency for the example folder to get it to work. This is only for examples which have all the files to match the system I am using (ie: xcode/visceral studio)

If you are including the addon while using the project generator (the recommended way of starting projects) then the example is not added.
