Question 1

How do I use BindBC-SDL with SDL2?

Accepted Answer

BindBC-SDL is for SDL3; for SDL2, you must use the separate SDL2 branch, which may have different maintenance and API support. This means switching branches and potentially adapting to older SDL2 features.

Question 2

BindBC-SDL vs DerelictSDL for D?

Accepted Answer

BindBC-SDL is newer and optimized for SDL3 with BetterC and @nogc support, while DerelictSDL targets SDL2 and may be simpler but less integrated with modern D features. BindBC-SDL is better for performance-critical, low-level projects.

Question 3

How to handle errors when loading SDL libraries dynamically?

Accepted Answer

Use BindBC-Loader's error handling API to log messages from the errors array. Check the return value of load functions (e.g., loadSDL) for LoadMsg enums like noLibrary or badLibrary, and abort or show user-friendly messages as needed.

Question 4

How to compile BindBC-SDL for BetterC?

Accepted Answer

Set the subConfiguration to 'staticBC' or 'dynamicBC' in your dub file, and ensure your code avoids D runtime features. You'll also need to manage version identifiers and library linking manually for static builds.

Question 5

What's the difference between static and dynamic bindings?

Accepted Answer

Static bindings link at compile-time and may have runtime dependencies, while dynamic bindings load libraries at runtime, offering flexibility but requiring manual loading. Static is simpler for deployment, dynamic for plugin-like architectures.

Question 6

How to set up SDL_main entry points in D?

Accepted Answer

Use the makeSDLMain mixin with parameters for argument handling and dynamic loading code. Be cautious with DRuntime initialization—it's complex and requires re-implementing runtime features if using extern(C) main with BetterC.

Question 7

Can BindBC-SDL be used for embedded or console development?

Accepted Answer

Yes, through support for special platforms like Nintendo 3DS and Sony Vita, but you'll need to handle platform-specific SDL builds and ensure the bindings are configured with the correct version identifiers for those targets.
