qt linux core.h not found

When I open my C++ project in Qt Creator and start to build this I take error

/home/ant/Desktop/UnrealEngine-release/Engine/Source/Developer/AITestSuite/Private/AITestSuitePrivatePCH.h:3: error: Core.h: No such file or directory
#include “Core.h”

I don’t change anything in .pro file. I use UE 4.7.6 and Linux mint. Can anybody help me with this?

Could you please switch to epic/4.8 branch first, and try there?

The 4.7 (release) lacks many fixes that the Linux community submitted into 4.8 so your problem might be resolved by simply changing the branch.

Else, if the above fails, please submit this to AnswerHub under Linux, so that Epic can track the issue.
