Could not be compiled. Try rebuilding from source manually.

This is the message the project browser provides me

here is the error message when I try to build inside Visual studio.

My version is 4.12.5 ,Windows 8.1 ,and I installed ue4 in D:/drive .

From log it seems that you compiled but the linker failed. Are you including the proper header files which has the functions you are refering to?

the strangest thing is 4.1 version of github works properly but the project created by the 4.12.5 installed via Launcher gives the problem.
