Hi,
I would like to build a special version of the Editor on Mac. But when I try to built the UE4 target I have one issue :
Target : UE4_Build
issue : Shell Script Invocation Error Group
Runtime/Core/Public/Misc/CString.h:364:31: error: instantiation of variable 'TCStringSpcHelper<wchar_t>::SpcArray' required here, but no definition is available -Werror,-Wundefined-var-template]
