AK::SoundEngine::Suspend() in UE4.19 doesn't compile with LNK error

Question

Wwise plugin info "Version" : 201720933, "VersionName" : "2017.2.4.6590.933", "EngineVersion" : "4.19.0"

I am trying to use Suspend(bool) and WakeupFromSuspend() in UE4 but I have link error on methods I'm not even using. I guess I missed something.

I put AKAdio in the build.cs

In my cpp:

#include <AK/SoundEngine/Common/AkSoundEngine.h>

uint8 UMiscBlueprintFunctionLibrary::MuteWwise(bool mute)
{
    AKRESULT result = AKRESULT::AK_Fail;
    if (mute)
        AK::SoundEngine::Suspend(false);
    else
        result = AKRESULT::AK_Fail; //AK::SoundEngine::WakeupFromSuspend();
    return uint8(result);
}

 

The compilation error I get :

1>AkMemoryMgr.lib(AkMemoryMgrBase.obj) : error LNK2019: symbole externe non rÚsolu "void * __cdecl AK::AllocHook(unsigned __int64)" (?AllocHook@AK@@YAPEAX_K@Z) rÚfÚrencÚ dans la fonction "enum AKRESULT __cdecl AK::MemoryMgr::InitBase(long,unsigned long)" (?InitBase@MemoryMgr@AK@@YA?AW4AKRESULT@@JK@Z)

As soon as I comment the method call my project compile juste fine, even the AKRESULT enum doesn't throw error.

 

What did I do wrong and where do these errors come from ?

How can I effectively cal this "suspend" method in my UE4 project ?

Answer 1

read the error message carefully.

AK::AllocHook(unsigned __int64) and friends are missing because *you* are supposed to provide them.

for each missing symbol define and implement it and link.exe will find and use them.

hope that helps.
