Hi icesand,
thank you for your email.
I have added a FL_LOG(Power->defuzzify()); at the end to produce an output value from the application. I have revised your code and could not find any problem. I have compiled it under Linux using: g++ Test.cpp -Ifuzzylite -Lfuzzylite/bin -lfuzzylite and I have found no issues either, the result from executing the application is an output value of 0.75.
Could you try cleaning and building your application again? Have you modified fuzzylite’s source code? Perhaps try to compile from console such a small example just to ensure you have the right settings in VS.
I will try within minutes to compile in Windows to find out if there is something I am missing.
Cheers,
Juan
