Lots of errors when compiling project using FMOD with MinGW

I decided to use FMOD for sound playback in my project, but I'm getting lots of compiler errors which I am unsure of how to fix.

The header file of the class using FMOD looks more or less like this:

#ifndef PROJECTNAME_SOUNDMANAGER_H_
#define PROJECTNAME_SOUNDMANAGER_H_

#include <iostream>

#include <fmod.h>
#include <fmod.hpp>
#include <fmod_errors.h>

class SoundManager {
    public:
        static SoundManager &instance();
        void play(char *data, size_t size, bool loop=false);
        void stopAll();
    private:
        void ERRCHECK(FMOD_RESULT result);
        SoundManager() : mSystem(nullptr) {
            initFMOD();
        }
        SoundManager(const SoundManager &other);
        SoundManager &operator=(const SoundManager &other);
        void initFMOD();
        FMOD::System *mSystem;
        FMOD::Sound *mSound;
        FMOD::Channel *mSoundChannel;
};

#endif // PROJECTNAME_SOUNDMANAGER_H_

And here are some of the compilation errors:

...../api/inc/fmod.h:1054:33: error: expected ')' before '*' token
...../api/inc/fmod.h:1056:33: error: expected ')' before '*' token

...../api/inc/fmod.hpp:59:21: error: conflicts with previous declaration 'FMOD_RESULT FMOD::System::_stdcall'
.....

If it makes any difference, I'm compiling with -std=c++0x.

I've tried searching but I wasn't able to find anything that helps me with these errors.

Please note that I'm using FMOD Ex 4.44.06.

EDIT: I seem to have found the problem. When I make a minimal example and compile it without -std=c++0x, everything compiles fine. However, if I add that flag, I get the same errors as with this project. Is there no way to make FMOD play nice with C++11?

Under MSYS2 and GCC v5.4.0 I was facing the same problem. The solution was add the compile flag -D__CYGWIN32__.

This is due the following in fmod.h:

#if defined(__CYGWIN32__)
    #define F_CDECL __cdecl
    #define F_STDCALL __stdcall
    #define F_DECLSPEC __declspec
    #define F_DLLEXPORT ( dllexport )
#elif defined(WIN32) || defined(_WIN32) || defined(__WIN32__) || defined(_WIN64)
    #define F_CDECL _cdecl
    #define F_STDCALL _stdcall
    #define F_DECLSPEC __declspec
    #define F_DLLEXPORT ( dllexport )
...

My guess is that there's something defined as a macro or something not defined as a macro. Now, your task is to provide a minimal example. This can mean manually deleting large pieces of code or copying code from the header files. Do that until you can provide the offending code in a few lines. I guess that doing so, you will find the problem yourself.

There are a few things I noticed with the little code you provided:

  • fmod() is actually a function and I could imagine a few compilers providing this as a macro, which in turn conflicts with #include, but that doesn't seem to be your problem.
  • You include both fmod.h and fmod.hpp, which looks suspicious.
  • void ERRCHECK(FMOD_RESULT result); looks like a mix between function and macro.
  • play() should probably take a const char* data.
