This updates all references to SDL 2.0.22 to SDL 2.24.0, including the
Docker container that I maintain for Linux CI.
Be warned, this release of SDL updates the versioning scheme to be less
dumb. The previous version is 2.0.22, this release is 2.24.0 (so the
last number can be properly used for patch-level version releases).
2.0.22 just released 40 minutes ago.
This also updates the `Dockerfile` to use the URL from the GitHub
releases page, instead of SDL's servers.
I've also pushed a new Docker container to
`ghcr.io/infoteddy/vvvvvv-build`.
While we can't fix Canonical, we can at least work around them, and help
people on Ubuntu out by linking them to my comment listing the
currently-known workarounds.
As a partial fix for #618, adding the SDL2 version number to the README
will clarify that you need a specific version of SDL2 in order to
compile (and run) the current version of the game (2.3 at the time of
writing); in the future, the SDL2 dependency will be upgraded with each
SDL release.
This is to avoid error messages that complain about missing symbols like
SDL_zeroa() (added in SDL 2.0.14) not being present at the time of
compilation.
Closes#626.
