I’m trying to build the generate\_tone example, in the Visual Studio 2015 IDE, but inexorably I only obtain a lot of LNK2019 errors by the compiler. I’ve read of this issue in many forums, but none of the solutions proposed seems to work. I’m quite desperate, because FMOD seems to be a great tool, but I can’t use it for some reason I cannot decipher. Please someone help me!!! ---

Functions prefixed with “Common” are part of our example framework and not part of FMOD itself. This code is added to the examples via common.cpp and common\_platform.cpp. Developers would usually replace this code with their own application code. ---

Ok, but (I’m not a professional programmer) what should I do to make the examples work? Thanks, really, for your help… ---

Anywhere there is a function with Common in the name, it will need to be removed. (eg. Common\_Fatal, Common\_Draw, Common\_Init) These are used and self contained in the individual example projects.
