compile and run c++ code runtime

问题:

Does anyone know how to compile your c++ code wich you write while your program is already running?

And later i would like to run that code.

I want to do this because I am trying to make a game that woul teach you programing and so the user would have to write the code while the game is running and test it.

Thanks for any help

You'd have an easier time if you chose a language that was designed with embedding in mind - like LUA or python. For C++, you'd have to go for something extremely clumsy and fragile like invoking an external compiler (which is also a logistics nightmare when shipping your game), or something as complex as integrating a compiler in your game (probably doable with llvm components, but...)

Also, for "teaching programming", C++ probably isn't the best language :)

You have to call the compiler to compile and link the user-entered code. This has to be made either into an executable that is then run from another process you create, or as a library that you dynamically load and call.

How this is done is different on POSIX platforms (like Linux and OSX) and Windows.
