Thanks for your answer. Sorry for my ignorance, but with my limited knowledge, I don’t always know what’s directly related to Fmod or not. But I understand that there are header files that can only be used for C++ and not for C. it’s logical, I just didn’t think of it. I also now understand that I need to reference stdlib.h instead of cstdlib.h - and maybe there’s a reference here to the other header files that get errors - but the problem is that I don’t understand where the reference to cstdlib is made. Because I can’t find it neither in the main file nor in the header files it refers to, while I also have been looking in the project properties, but can’t find it there either. This would then probably be an issue more suitable for the MSDN forum, but since we’re already at it, I ask you for now. Maybe it also can be useful to others.
Thanks in advance
