LanternEngine/engine/packaging/linux/Dockerfile

# Linux build environment of the Lantern Engine (packaging/linux/build.sh runs the build in it).
# Ubuntu 24.04: the package runs on glibc 2.39 and later (Ubuntu 24.04, Debian 13, Fedora 40,
# Arch, SteamOS 3.6, Bazzite). The libraries the Windows build takes from MSYS2 are built here at
# the same versions, static where they can be; SDL3 is the one shared library shipped
# (engine/out/gpu/libSDL3.so.0). Vulkan, X11 and OpenSSL 3 come from the player's system.
