Bug#1038182: cytadela: Depends on SDL 1.2

[Simon McVittie]

Source: cytadela
Tags: trixie sid
User: pkg-sdl-maintainers at lists.alioth.debian.org
Usertags: libsdl1.2

This package has a Depends or Build-Depends on SDL version 1.2, which
is unmaintained upstream.

If possible, please port this package to SDL 2 and close this bug. There
is a migration guide at <https://wiki.libsdl.org/SDL2/MigrationGuide>,
and examples of successful ports from SDL 1.2 to SDL 2 can be found in
the commit history of packages like darkplaces and ioquake3.

If it is not possible to port to SDL 2, please test the package with
libsdl1.2-compat-shim (preferably version 1.2.64 or later), and leave
this bug open to track the package as still using SDL 1.2 APIs.

libsdl1.2-compat-shim is a compatibility layer that provides the SDL 1.2
API/ABI by using SDL 2: it has already replaced the "classic" SDL 1.2
library in some other distributions like Fedora and Arch, and my intention
is to do the same in Debian during the trixie release cycle.

It is *not* necessary to change dependencies from libsdl1.2debian to
libsdl1.2-compat-shim, or from libsdl1.2-dev to libsdl1.2-compat-dev.
My intention is to make a future version of sdl12-compat take over
the old package names, to minimize the changes that are required in
dependent packages.

The interesting scenarios to test with libsdl1.2-compat-shim are:

1. Install libsdl1.2-compat-shim and run the program in an X11 environment,
   such as "GNOME on Xorg" or XFCE.
   ($XDG_RUNTIME_DIR/wayland-* should not exist)
2. Install libsdl1.2-compat-shim and run the program in a Wayland
   environment such as GNOME's default mode, using Xwayland.
   ($XDG_RUNTIME_DIR/wayland-* should exist)
3. Install libsdl1.2-compat-shim and run the program in a Wayland
   environment, but this time with environment variable
   SDL_VIDEODRIVER=wayland so that it uses the native Wayland interface
   (this is not currently the default for SDL 2).
4. Install libsdl1.2-compat-dev and recompile the package.

Note that using libsdl1.2-compat and LD_LIBRARY_PATH is not sufficient if
the package contains programs that are setgid games. See
<https://github.com/libsdl-org/sdl12-compat/blob/main/HOW_TO_TEST_GAMES.md>
for more information.

If any of those fail, please report it as a bug in the
libsdl1.2-compat-shim or libsdl1.2-compat-dev package as appropriate,
with "affects" pointing to the program that is affected.

Thanks,
