I am trying to port a project from 4.14 to 4.16 and faced strange build errors. So I tried to build other projects and I found out I can’t compile any of the engine’s c++ templates (third person c++/first person/flying etc.)
with PCH (PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs) I get these 2 errors :
error C2855: command-line option '/Z7' inconsistent with precompiled header
error C2859: ...\SharedPCH.UnrealEd.h.pdb is not the pdb file that was used when this precompiled header was created, recreate the precompiled header.
With no PCH (PCHUsage = PCHUsageMode.NoSharedPCHs) I get this:
All source files in module "ModuleName" must include the same precompiled header first.
Currently "D:\Unreal Projects\ModuleName\Source\ModuleName\ModuleName.h" is included by most of the source files.
The following source files are not including "D:\Unreal Projects\ModuleName\Source\ModuleName\ModuleName.h" as their first include :
I get these same errors from all templates with no modifications.
Other projects compile fine in 4.14.
Using VS 2015, vanilla build of the engine.
Any idea what’s causing this ?
