UE4 Integration... Can't Open UE4-AkAudio.lib

Question

I'm trying to package for UE4.11.1 and WW2016.1.1, and I've been running into problems. I followed the installation procedure for an engine plugin to a T. The first error I got was unable to link to AKMP3Source.lib. Luckily I found that online, and added it to the libraries. But now I'm getting:

LINK : fatal error LNK1181: cannot open input file 'C:\Program Files (x86)\Epic Games\4.11\Engine\Plugins\Wwise\Binaries\Win64\UE4-AkAudio.lib'

That lib file doesn't exist in that directory. Nor does it exist in the equivalent folder in the wwise integration package download, so I'm not sure where it is meant to come from. Does it get compiled fresh with every make? What am I doing wrong?

Thank you for any help!

Make sure you followed the installation instructions, found here: https://www.audiokinetic.com/library/edge/?source=UE4&id=installation.html

Yes, followed them very carefully. Many times. The issue can be replicated on different computers.

Could you please post a full log of when you try to package your game? Thanks!

We have something similar happening with Wwise Engine Integration (current) on UE4.19.1. We have AKAudio specified in our public module dependencies. Any ideas how to resolve it? - thanks

I determined the cause of the problem we're having. In the response file being passed to the linker (ex: Projects\TestProject\Intermediate\Build\Win64\TestProject\Development\TestProject.exe.response

1. One of the Ak libs, AkAutobahn.lib, is not being passed to the linker (needs "AkAutobahn.lib" in lib list)



2. The vc150 lib path is being chosen...

    Plugins\Wwise\ThirdParty\x64_vc150\Profile\lib

...and not the vc140 lib path...


    Plugins\Wwise\ThirdParty\x64_vc140\Profile\lib

...when the rest of the project libs appear to be vc140. This might possibly be related to the use of VS2017 as a compiler set which includes the VS2015 targets. Unreal has tested this scenario.

I'm working on a solution...

Update: Looking at Plugins\Wwise\Source\AkAudio\AkAudio.Build.cs

WRT vc_150: In VcGetVisualStudioVersion(), it's selecting which vcrt to use based on the version of VisualStudio being reported. My gut tells me that's probably not correct. Instead, I'm guessing that the vcrt version is set in some property bucket. I'll dig around for it...

if (Compiler == (WindowsCompiler)Enum.Parse(typeof(WindowsCompiler), "VisualStudio2017"))
{
    VSVersion = "vc150";
}


WRT AkAutobahn.lib: In the SupportsAkAutobahn() method it's explicitly not including the lib when VisualStudio2017 is the compiler. That's feels like an old workaround that needs to be removed...

if (Compiler == (WindowsCompiler)Enum.Parse(typeof(WindowsCompiler), "VisualStudio2017"))
{
    CompilerSupported = false;
}

Given that the lib is provided for both the vc140 and vc150 sets - everywhere the rest of the Ak libs are provided.

Resolution: Commenting out the following lines resolves the problem when building under VisualStudio 2017...

            // BUGBUG: 2018-4-25 - PaulBro disabled to work around build problems.
            // See https://www.audiokinetic.com/qa/2573/ue4-integration-cant-open-ue4-akaudio-lib?show=4696#c4696
            bool CompilerSupported = true;
            //try
            //{
                //if (Compiler == (WindowsCompiler)Enum.Parse(typeof(WindowsCompiler), "VisualStudio2017"))
                //{
                    //CompilerSupported = false;
                //}
            //}
            //catch (Exception)
            //{
            //}

Answer 2

I have te same error how did you solve it ?

The fixed E4\Engine\Plugins\Wwise\Source\AkAudio\AkAudio.Build.cs in recent releases. See the workaround in my code comments, above, which are no longer necessary.
