AkSoundEngine.lib(AkLEngine.obj) : error LNK2019: unresolved external symbol __imp__RegisterDeviceNotification

Question

Hello everyone,

 

I am trying to integrate wwise into our windows 8.1 project. and keep getting the same errors.We are using Visual Studio 2015.

I have set the additinal lib directory to Wwise v2015.1.5 build 5533\SDK\Win32_vc120\Debug\lib

I have also set the additional include directory to Wwise v2015.1.5 build 5533\SDK\include

Our platform tool set is set to Visual Studio 2013(v120)

Everything compiles fine. But the moment I call AK::MemoryMgr::init(someval); All hell brokes and I endup with the following 6 errors

I am wondering if I am using the correct lib files (Win32_vc120). I have also tried to use (Metro_Win32_vc120) libs but they also bring up some other linking errors. I hope some one could help us on this as we are literally stuck on this issue.

Thank you in advance!

Ok Just managed to solve the problem! On this occasion the reason I was having these errors was because i was using wrong lib files. I was using the Win32 libs. which in fact it should have been Metro_Win32 since I am doing a windows 8.1 app.  Previously what made me confused is that when i added the correct libs, I was still getting bunch of errors Here is some of it. I managed to solve that problem too by adding the functions within the threadEmulation name space into the AK name space. I am not sure if this is a correct way of doing it but if someone knows a proper way of doing it please do let me know. Followings were the errors i was getting.

EDIT: I think I managed to get things done in a way it suppose to. If you are like me and if you keep getting unresolved externals errors on ThreadEmulation on windows 8.1. Just add the following code into your wwise integration class cpp file.

  #define AK_IMPLEMENT_THREAD_EMULATION
#include <AK/Tools/Win32/ThreadEmulation.h>

Note that it has to be before the #include your_wwise_Integration_class.h.
