Good day,
I’m currently having problems building Unreal 4.9 with Lua support.
I followed the instructions in the readme and built Lua release for the both architectures.
Then I fetched all the dependencies with Setup.bat after which I generated the projects with GenerateProjectFiles.bat.
I basically just followed the readme in the .\Engine\Plugins\ScriptPlugin\Source\Lua
It refuses to compile unfortunately.
Visual Studio 2012 output:
