I download UE4 4.10.2 from GitHUB, select “Development Editor” in Visual Studio 2015. But my build failed launch to HTML5.
Internet suggested to select “Development” to build, unfortunately the build failed with errors in Visual Studio.

Hi!

Open the UE4.sln and switch to the “Development/HTML5” configuration and build additional libs.

Maybe you need redownload sources and rebuild it. I downloaded the UE 4.10.2 from GitHub. I launched Start.bat. Done. I launched GenerateProjectFiles.bat -2015. Done. I clicked on UE4.sln and open this project in VS 2015. Build the UE4 with configuration “Development Editor/Win64”. Done. Next I switch to configuration “Development/HTML5”. Build. Done. I launched UE4 Editor and created TPS project. I launched packaging project for HTML5. Done.

Next I switch to configuration “Development/HTML5”. Build. Done.

Did you got 48 errors and 1 warning after the build process completed, like my screen shot above?

I did the same but VS2015 shows those error when I build the UE with configuration “Development/HTML5”

Is it safe to ignore the compiler warning and error?
