nielsmh nicely correct us in #8641, pointing out the old comment
is not telling a complete truth. The result is the same, but it
is better to not mislead future-us.
These bundles can be opened on any "modern" Linux machine with
a driver that SDL2 supports.
Machines needs at least glibc 2.15, which was released 10 years ago.
It is build with CentOS 7 as base, and only assumes the following
libraries are available on the system:
- libc
- libdl
- libgcc_s
- libpthread
- librt
- libstdc++
All other libraries the game depends on are bundled together with
the game, so users don't need any library installed to use this
bundle. The downside of course is that this increases the binary
size a bit: 30 MiB of libraries are in this bundle.
RPATH is used to make ld-linux find the folder libraries are
stored in; however, system libraries are always used before these,
in the assumption libraries on the user system are more up-to-date.
Using -DOPTION_PACKAGE_DEPENDENCIES=ON switches on packaging
of libraries in the "lib" folder. This requires CMake 3.16 to
be installed; otherwise it will fail.
We use CMakeListsTxtAdvanced, and as such, we have to do this our
self via "-DCMAKE_BUILD_TYPE=RelWithDebInfo". Otherwise we are
producing Debug builds instead of Release builds. Oops.
This has several ways of being triggered:
- When creating a new release via the GitHub interface. Fully
automated that will produce new binaries, upload them, and it
will even update the website to tell about the new version.
- When triggered in an automated way from OpenTTD/workflows to
start a nightly.
- Manually via the Release workflow, which accepts branches,
Pull Requests and tags to build.
Rerunning a job is safe and should be without issues. Everything
retriggers and updates what-ever might have been broken. In fact,
except for dates, it should produce identical results.
