Creating a Game Engine with a C++ Compiler?

Solutons:


The only reason that I can see for including a compiler in an application is that you wish users to be able to write their own code in C++ which is compiled, linked, and executed at runtime. This isn’t a brilliant idea, and in fact there is a common game engine technique called scripting that allows users to do write their own code and have it executed.

A short extract from Jason Gregory’s Game Engine Architecture (third edition) from page 794 can be found below:

A scripting language can be defined as a programming language whose primary purpose is to permit users to control and customise the behaviour of a software application.

In the context of game engines, a scripting language is a high level, relatively easy-to-use programming language that provides its users with convenient access to most of the commonly used features of the engine. As such, a scripting language can be used by programmers and non-programmers alike to develop a new game or to customise – or “mod” – an existing game.

A short list of benefits of scripting:

  • You can only expose the parts of the engine to the scripting system that you want to.
  • The scripts are loaded at runtime and can be edited off-line without the engine needing to be recompiled.
  • They help support rapid iteration times and are sometimes quite lightweight.

I would suggest you look into adding scripting functionality as this would be a better solution to your problem. There are many scripting related questions on gamedev.stackexchange to get you started!

Yes, you can (and in my opinion should!) use the Visual C++ compiler. It is currently one of the best compilers out there.

Furthermore, while it is very interesting to write your own compiler, it’s not very wise to use it for speed-critical applications like games.
