Eh it is sometime errors :( about c2cs HOT 5 CLOSED

Unrecognized command or argument 'config.json'.

It's c2cs --config /path/to/config.json

from c2cs.

With C2CS version 5, the config.json you posted is first for CAstFfi.

castffi extract /path/to/config-linux.json
castffi merge --inputDirectoryPath /path/to/ast/directory --outputFilePath /path/to/cross-platform-ast.json
c2cs --config /path/to/config-cs.json

config-linux.json:

{
  "inputFilePath": "/usr/include/SDL/SDL.h",
  "userIncludeDirectories": [
    "/usr/include/SDL"
  ],
  "platforms": {
    "x86_64-unknown-linux-gnu": {},
  }
}

config-cs.json:

{
  "inputFilePath": "/path/to/cross-platform-ast.json",
  "outputFilePath": "/path/to/SDL.cs",
  "namespaceName": "",
  "className": "SDL"
}

from c2cs.

Okay thanks I will try again....

Oh I found generator can't find SDL_FillRect()

Unhandled exception. System.EntryPointNotFoundException: Unable to find an entry point named 'SDL_FillRect' in shared library 'SDL3'.
   at bottlenoselabs.SDL.SDL_FillRect(SDL_Surface* dst, SDL_Rect* rect, UInt32 color)

I already downloaded and tested from repository of your helloworld and it shows FillRect has not SDL_FillRect() It is impossible? I believe it is new version won't use longer with old SDL_FillRect()....

from c2cs.

You may need to re-point the SDL submodule to v2; perhaps in v3 of SDL SDL_FillRect is no longer there?

from c2cs.

Yes check out new version of SDL3 but I have already released SDL3 with ClangSharpPInvokeGenerator. Can you check my repository DeafMan1983.Interop.SDL3

If you have problem with sbyte * or string conversion.

Then you can try out if you have example sdl2/3 with SDL3 C#.

Enjoy your happy development! You can find in nuget.org also both packages. But both support Net 7.0
