I am moving bunch of c++ code from older project to UE4 project. I get link error LNK2001 or LNK1120 with empty description, which makes it very difficult to locate the problem.
I am using VS2017 community 15.9.21, with UE4 4.23 and building config development editor targeted win64. I have other c++ projects, on which vs2017 can correctly report details of link error, so I suspect it is caused by unreal tool chain.
Any thought?
