I am having some problems compiling the current GameSparks plugin for UE4, this is the error log I get after adding in GameSparks plugin code:

2>C:\Program Files (x86)\Windows Kits\8.1\include\shared\ws2def.h(249): error C2872: 'INT': ambiguous symbol

2>C:\Program Files (x86)\Windows Kits\8.1\include\shared\ws2def.h(275): error C2872: 'INT': ambiguous symbol

 There are many more lines, and it stops at 100 errors.

This doesn't happen with the marketplace plugin, but the marketplace plugin doesn't have the features I need.

Anyone have any idea where this needs to be fixed?

Thanks

Currently I only have the UE 4.13.2 code compiled at the moment, so I haven't tried it yet with another build.

System is Windows 10, Visual Studio 2015 Pro.

This is also a clean build of UE4, as a attempted to rebuild the entire base to get it working.

Thanks

We had the same issue.  Resolved it by following this: 

https://answers.unrealengine.com/questions/27560/trouble-using-windows-includes-with-dword-int.html

Required edits to 0001mbedtls.cpp, 0002GSAmalgamated.cpp and 0001GameSparksRTAmalgamated.cpp.

I can confirm that this indeed has fixed the issue... also for some reason (MS most likely) _CRT_SECURE_NO_WARNINGS doesn't work as well, so adding in # pragma warning(disable: 4996) makes the build look nicer.

I will look into a PR in the near future if this is not fixed first

I have added a PR, I didn't have to add anything to 0001GameSparksRTAmalgamated.cpp to get it to compile, but I haven't really attempted to use it yet in a build.
