Not able to build engine code for 4.18.3.
Did the following:

  • Downloaded the zip version of 4.18.3 and unpacked.
  • Ran Setup.bat
    *Ran GenerateProjectFiles with -2017 option
    *Selected Development Editor and Win 64 options in Visual Studio 2017
    *Selected UE4 project and chose Build All
    After 35 mins of compile it bombed…

I have given the error log below:
Any tips would be appreciated:

not a clue, would start out and understand what Shader Compiler Worker is, it appears almost like the engine is having issue. Now how about trying to verify install? what happens

your path is too long. (most likely) if hitting build errors out on the same project then try shortening the unreal root.

C:\UE4_Engine_Code\UnrealEngine-4.18.3-release\ ← this needs to be much shorter

try this

C:\Code\UE4\ ← this has a much higher chance of success.

In fact, you most likely got errors when you ran Setup.bat. And you ignored them as if they weren’t telling you that the path was too friggin long.
