First,I download 4.73 on github, and follow A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums change SteamSDK to 1.32. and compiled, no error.but there was no UE4Editor-OnlineSubsystemSteam built.
So, I change UE4Editor.target.cs delelt UEbuildconfiguration.bCompileSteamOSS==true Conditions. then I compile,and got some error…and I follow 4.7.1 Steamworks integration, engine won't compile - C++ - Unreal Engine Forums ,add code in SteamVRPrivatePCH.h and OnlineSubsystemSteamPrivatePCH.h …then I got error this:

`D:\Unreal Engine\UnrealEngine-4.7\Engine\Source\Runtime\Online\OnlineSubsystemSteam\Private\IPAddressSteam.cpp(21): error C2065: “array”: Undeclared identifier
1>D:\Unreal Engine\UnrealEngine-4.7\Engine\Source\Runtime\Online\OnlineSubsystemSteam\Private\OnlineIdentityInterfaceSteam.cpp(185): error C2065: “array”: Undeclared identifier

1>D:\Unreal Engine\UnrealEngine-4.7\Engine\Source\Runtime\Online\OnlineSubsystemSteam\Private\OnlineSessionAsyncServerSteam.cpp(1202): error C2065: “array”: Undeclared identifier

So,how can I to do next?
