Hi,
I think there is something wrong with your code. If you were able to build and run the example application, then the problem is with your new application. I am not familiar with Visual Studio, but I think you should try using CMake with “NMake Makefiles”, like I do in “build.bat”.
A quick option to test the library is to build it and execute fuzzylite.exe. Do you have this file in your system?
