Curious about DirectX -> OpenGL

[kryszcztov]

Out of curiosity, I'd like to know what would be required to port Civ4 to the GNU/Linux platform. I know it mainly deals with changing some code from DirectX to OpenGL, but it's still Chinese to me. So :
- What exactly must be done ?
- Is anything feasible with what we have now (SDK...) ?

Once again, just out of curiosity.

The graphics engine was unfortunately left out of the SDK.

OK. Isn't it possible to start building our own free graphics engine, and graft it on what is released, so as to run the whole on Linux ? This could even be a simple 2D-engine using OpenGL or SDL... Or am I missing a point ?

Yes, but...

This is not permitted by the terms and conditions of the license agreement Firaxis released the game with.

Civ4 may be very moddable, but it is NOT open source.

Perhaps you would like to look into the FreeCiv project.

No, I'd prefer Firaxis to port Civ4 to Linux. Thanks for your answers.
