UE4 EyeXSamples Build Fail

[Ahmed Al-Hulaibi]

As the title says, when building the EyeXSamples project, I am experiencing build errors. I’ve followed the GitHub instructions closely and repeated the process multiple times to no avail. All other UE4 C++ projects are building and running without any errors, so this seems to be isolated to the EyeX SDK. Anyone experienced this or have a solution/workaround?

Windows 7 64 bit
Unreal Engine 4.8.1
Visual Studio 2013 Community Edition

It seems the latest version of the Unreal Engine broke the plugin for some reason. Adding “#include “EyeXTypes.h”” to EyeXPlayerController.h fixed the problem for me. The include has to be before the generated header file.

Thanks that worked!
