Voice SDK failed to compile with UE5.5 Oculus fork.

Hi there!

I'm trying to implement Voice SDK into my project but when I install it (with the batch file adressed in documentation), I'm not able to compile project or even start the editor. Anyone using Voice SDK with 5.5 succesfully?

The last version of Voice SDK is Release 67.0.0. Is maybe 72.0.0 coming any soon? 

Thanks

      I would appriciate more humanoid answer than this "copy-paste" nonsense generated answer. Of course I've used horiyon/support page as a start for finding an answer. I didn't find so I've ended up asking here.

        I know you asked for unreal 5.5 but for me it works perfectly on unreal 4.27 v49. I still use this version because I started a project at 2023 and only finished now. I also have on Unreal 5.3 working. It was working and now on unreal 5.5 it stopped?

        Thanks for the answer! But I suppose the problem is with the version:

          Hi, did you find a solution? I also encountered this problem on version 5.5! I refuse to simply downgrade to 5.4(

          Hi all. You are correct, there are a number of errors when compiling Voice SDK on UE5.5 due to changes in the engine. It looks like you will need the 3 fixes below. You can use these patches until an updated SDK is available. 

          1 - Don't include deprecated IHttpThreadedRequest.cpp
          In voicesdk/wit-unreal/Source/Wit/Private/Wit/Request/HTTP/WitHttpEngineIncludes.cpp change this:

          #if UE_VERSION_OLDER_THAN(5, 3, 0)
#else
#include "IHttpThreadedRequest.cpp"
#endif


          to this:

          #if UE_VERSION_OLDER_THAN(5, 3, 0)
#else
#if UE_VERSION_OLDER_THAN(5, 5, 0)
#include "IHttpThreadedRequest.cpp"
#endif
#endif

           
          2 - Include EngineVersionComparison.h in WitRequestSubsystem.h

          #include "Misc/EngineVersionComparison.h"


          3 - Make new engine defines public
          In Engine\Source\Runtime\Online\HTTP\HTTP.Build.cs, change these lines from Private

          PrivateDefinitions.Add("UE_HTTP_SUPPORT_TO_INCREASE_MAX_REQUESTS_AT_RUNTIME=" + (bPlatformSupportToIncreaseMaxRequestsAtRuntime ? "1" : "0"));
...
PrivateDefinitions.Add("UE_HTTP_DEFAULT_MAX_CONCURRENT_REQUESTS=" + DefaultMaxConcurrentRequests);

           to Public

          PublicDefinitions.Add("UE_HTTP_SUPPORT_TO_INCREASE_MAX_REQUESTS_AT_RUNTIME=" + (bPlatformSupportToIncreaseMaxRequestsAtRuntime ? "1" : "0"));
...
PublicDefinitions.Add("UE_HTTP_DEFAULT_MAX_CONCURRENT_REQUESTS=" + DefaultMaxConcurrentRequests);

           
          With these fixes, I was able to compile and use the Voice SDK in 5.5. Let us know if that works for you too.

            For anyone that wants to avoid engine changes or is using the vanilla UE5.5 release, you can skip step 3 above and instead add the following code to wit-unreal/Source/Wit/Private/Wit/Request/HTTP/WitHttpEngineIncludes.cpp

            #if UE_VERSION_OLDER_THAN(5, 5, 0)
#else
// These defines are private. Redefining here as they are required to compile HttpThread.cpp.
// Making them public in HTTP.Build.cs would be an engine change and this plugin needs to work with vanilla UE5. 
#define UE_HTTP_DEFAULT_MAX_CONCURRENT_REQUESTS INT_MAX //int DefaultMaxConcurrentRequests { get { return int.MaxValue; } }
#define UE_HTTP_SUPPORT_TO_INCREASE_MAX_REQUESTS_AT_RUNTIME 1 //(bPlatformSupportToIncreaseMaxRequestsAtRuntime ? "1" : "0")
#endif

             

            I have this at line 32.
