Freeciv

Prerequisites for the SDL3 client:

----------------------------------

- The "SDL3" library.

"Simple DirectMedia Layer is a cross-platform multimedia library designed

to provide low level access to audio, keyboard, mouse, joystick, 3D hardware

via OpenGL, and 2D video framebuffer." (https://www.libsdl.org/)

These features make it a good choice for portable games. You may obtain it

at:

https://github.com/libsdl-org/SDL/releases/download/release-3.2.10/SDL3-3.2.10.tar.gz

To compile the client using the "SDL3" library add "-Dclient=sdl3"

to the Freeciv meson execution.

- The "SDL3_image" library.

This library loads the PNG images (with the help of libpng) and converts

them to "SDL surfaces" that can be handled by the "SDL" library. You may

obtain it at:

https://github.com/libsdl-org/SDL_image/releases/download/release-3.2.4/SDL3_image-3.2.4.tar.gz

- The "SDL3_ttf" library.

https://github.com/libsdl-org/SDL_ttf/releases/download/release-3.2.2/SDL3_ttf-3.2.2.tar.gz

- The "freetype" library.

This library helps to render text for the SDL3 client, using an externally

provided TrueType font. You may obtain it at:

https://download.savannah.gnu.org/releases/freetype/freetype-2.13.3.tar.xz
