Juan, after your instructions, everything is working fine with fuzzylite and QT, but theres one issue that i cannot figure out why is happening.
If I build my program inside QT, and run it inside the IDE, it works fine. But if i try to run the program for the executable, outside the IDE, it’s not running, and it’s only happening when I add a function to my program which contains the “fl::Engine* engine = new fl::Engine;”.
It sounds to me that you are having issues with the linking of the library. I think it has to do with the location of the fuzzylite.[dll|so|dylib] file and the location of your executable. For me, I generally just use the fuzzylite-static.[lib|a] library.
