I have integrated Vivox into a MP project of mine, based on the Shootergame template - just as the Vivox sample basically. However, when cooking, compiling the Linux Binaries fails during linking with hundreds of errors like this one:
We recommend using the #if !UE_SERVER pre-processor macro around any voice code. This will prevent issues when building for your dedicated server since it would not actually be using the voice functionality of the SDK. Please note, any usernames, channel names, or access tokens should be generated through your own logic and not via the Vivox Core Unreal plugin.
