Upgrade to SDL3 #578

This pretty much works on my machine, so I figure it's close enough to ready to be tested on a wider range of setups.

I haven't been able to resolve the Linux/Wayland splash screen problem where the game screen ends up largely off screen due to Wayland not allowing programatic window placement, so we'll have to continue with the separate splash screen program work around for now.

On Windows, Oolite starts with the window underneath the command prompt I'm launching from - I'm not sure what's causing that.

This is probably me, but I'm getting this error trying to compile locally.

src/Core/OOOpenGLOnly.h:58:10: fatal error: 'SDL3/SDL_opengl.h' file not found
   58 | #include <SDL3/SDL_opengl.h>
      |          ^~~~~~~~~~~~~~~~~~~

Is there something else I need to do?

Sorry, you would need to install the SDL3 package, e.g., on Windows, running the ShellScripts/Windows/install_deps.sh script would do it

OK, install script has been run. The package now builds successfully. But the resultant executable doesn't run. I get a brief switch of the mouse pointer to an hourglass, then back to normal, and nothing appears. No splash, no game window. No error files in the oolite.app folder. No log files created.

Does it run from the command line within the MSYS2 environment?

cd oolite.app
./oolite.exe

It does! Why would it be different running the app from Explorer?

I'm guessing a missing dll.

This is a busy week for me - I hope to look at this PR in the weekend.

I wondered whether something still required the old SDL dll. But it's not listed when I run ldd oolite.exe and copying it manually into oolite.app didn't resolve things, so I guess it's not that.
