Can't create or build c++ project

Development Platform & Builds

Hi, I’m currently working on a game development project at my university, and I’ve chosen Unreal Engine 4 (version 4.27) to develop it. I’m very new to Unreal Engine.

My problem is that I want to add some C++ code to my project (as required by the university), but I encountered a build error when trying to build from Visual Studio Code or when creating a new C++ project in Unreal Engine.

I’ve try to research about problem, but i couldn’t find a solution to fix my problem T_T.

UE 4 has some code that modern toolchains flag with warnings, but since the build has “warnings as errors” turned on by default, this causes the build to fail.

Three options:

  1. Switch to developing in Unreal Engine 5 instead (any particular reason why you’re still preferring 4?).
  2. Configure the build settings to suppress these warnings (see: https://forums.unrealengine.com/t/wdeprecated-builtins-error-when-trying-to-build-ue4-on-xcode-15-0-1 – I know that this issue was reported for Xcode but the solution should be the same as for you).
  3. Fix the errors in the Unreal Engine source and compile your own build of the engine (this is hard, especially given that 4.27 is now more than 3 years old so there’s less support out there for it if you get stuck).
