sdl2-compat is a reimplementation of the SDL 2 API using SDL 3.
It can be tested by installing the libsdl2-compat-shim and
libsdl2-compat-dev packages from testing/unstable, or by installing the
libsdl2-2.0-0 and libsdl2-dev packages built by src:sdl2-compat in
experimental.
After discussion with SDL upstream, I'm looking into what needs to
happen for Debian (and indirectly Ubuntu) to replace "classic" SDL2
(src:libsdl2) with sdl2-compat, following in the footsteps of other
distros like Arch and Fedora that have already done this transition.
descent3 failed to build from source with libsdl2-dev provided by
src:sdl2-compat, with compiler errors indicating that it is using
CHAR_WIDTH as a local function or function-like macro. In C23,
<limits.h> declares CHAR_WIDTH as the width of char in bits, in practice
always 8 in Debian. I haven't looked into this in detail, but probably
this is because a sdl2-compat header contains `#include <limits.h>`
where the equivalent libsdl2 header did not.
This could likely be solved by building with -std=gnu17, or by renaming
the local definition of CHAR_WIDTH to something else, preferably
namespaced.
