LNK2019 XAudio2Create - unresolved symbol

I am trying to get in touch with the DirectX SDK. I managed to install it, created a new Win32 Console Project and added following lines

#include <iostream>
#include <xaudio2.h>

int main(int argc, char *argv[]){
IXAudio2* pXAudio = 0;
IXAudio2MasteringVoice *pXAudioMasterVoice = 0;
HRESULT hr;

CoInitializeEx(NULL, COINIT_MULTITHREADED);

hr = XAudio2Create(&pXAudio, 0, XAUDIO2_DEFAULT_PROCESSOR);
if(FAILED(hr)){
    CoUninitialize();
    return hr;
}

hr = pXAudio->CreateMasteringVoice(&pXAudioMasterVoice);
if(FAILED(hr)){
    pXAudio->Release();
    CoUninitialize();
    return hr;
}

CoUninitialize();
std::cout << "Done!" << std::endl;
}

The documentation says, that there is no xaudio2.lib to link to, but it is a COM-object, but I get LNK2019 - unresolved external symbol "__imp__XAudio2Create@12"

Here is the documentation.

Thank you for any hints.

Solution

  • XAudio2Create is not COM, it's a standard DLL export, so you do need to link with Xaudio2.lib. This library is available in %Program Files%\Windows Kits\8.0\Lib\win8\um (installed with the Windows 8 SDK).
