I wanted to be able to crosscompile for Linux using Toolchain so i downloaded UE 4.5.1 (including required files) from git [here][1]
And I was able to build i guess (development editor?) for Win64, but packaing for Linux fails, so i found i have to also build Development / Linux in Visual studio to be able to package for Linux from UE Win Editor.
I tried it, but i still get error as on image.
Yes i selected UE4 in the right panel of Visual Studio and then pressed Build.
