I have been attempting to use a modified version of these bindings in my game project. I have had to make some changes to get them working but i am stuck on the SDL_ttf.h binding.
I had to change the

s" SDL2" add-lib

to

s" SDL2_ttf" add-lib

I also had to comment out all of these functions to get it to compile however i need the function TTF_RenderText_Blended. I don't know if it's because it needs a SDL_Color struct or if it's not linking to the actual SDL library since this is not core SDL2. My project is here. https://github.com/JeremiahCheatham/Yellow-Snow/tree/main/Gforth-SDL2
