Package: libsdl2-dev
Version: 2.0.20+dfsg-2build1
Severity: normal
X-Debbugs-Cc: [email protected]
Dear Maintainer,
I think that libsdl-dev may possibly need its dependency list updating. I
noticed the issue in Ubuntu, but the dependencies in Ubuntu are essentially the
same as those in upstream Debian (apart from some things like libc and
pkg-config which presumably apply to all packages), so I am reporting it to you
too.
WHAT LED UP TO THE SITUATION?
I moved from Ubuntu 20.04 Focal Fossa to 22.04 Jammy Jellyfish. The Jammy
version of this package (2.2.20+dfsg-2build1) is behind the Debian Sid version,
but both versions have the same dependencies if there is a problem, then it is
still there.
(This is how I discovered the issue, but there is probably a much more minimal
reproduction case)
1. Downloaded the Simutrans-Extended repo:
https://github.com/jamespetts/simutrans-extended
2. Downloaded the dependencies, at a minimum libsdl2-dev
3. Followed the instructions there for building with autotools
EXPECTED RESULTS
Simutrans-Extended compiles correctly, as it did on Focal Fossa.
ACTUAL RESULTS
When I tried to build it on Jammy Jellyfish, the build failed with the
following errors from the linker:
/usr/bin/ld: cannot find -ldrm: No such file or directory
/usr/bin/ld: cannot find -lgbm: No such file or directory
/usr/bin/ld: cannot find -ldecor-0: No such file or directory
Installing Ubuntu's libdrm-dev, libgbm-dev, and libdecor-0-dev packages ("the
'missing' packages") solved that problem. But I wonder whether it might be a
packaging bug. I follow Simutrans-Extended development quite closely and we
have not intentionally introduced dependencies on those packages; I think they
have been brought in by SDL2.
If a program using sdl2-dev used to be able to compile without the 'missing'
packages, but now requires them, it seems to me that they are now dependencies
of sdl2-dev. Or at least should be 'suggests'. But I am not an expert on either
Debian packaging or SDL2.
COMMENTS
The 'missing' libraries are not direct dependencies of Simutrans. However, the
sdl2-0-0 packages in Debian and Ubuntu have recently added dependencies on
libgbm1, libdrm2, and libdecor-0-0.
Compare the Bullseye dependencies....
https://packages.debian.org/bullseye/libsdl2-2.0-0
......with the Bookworm dependencies:
https://packages.debian.org/bookworm/libsdl2-2.0-0
However, the Bookworm and Sid libsdl2-dev packages do **not** list dependencies
on the 'missing' -dev packages: https://packages.debian.org/bookworm/libsdl2-dev
I notice that SDL's own build guide lists those packages as dependencies for
building SDL2 itself on Focal Fossa:
https://github.com/libsdl-org/SDL/blob/main/docs/README-linux.md
But that change was made in February 2021 so it affects Ubuntu's version of
SDL2 in Jammy, not Focal:
https://github.com/libsdl-org/SDL/commit/2f4e9294aa260635d876b5699846adc458f555db
That change was before Bullseye was released so I am not sure how that fits
with the Debian timescale.
I initially asked about this on AskUbuntu and a comment there confirmed that
the required .so files are in (for example) libgbm-dev, not lib-gbm1:
https://askubuntu.com/questions/1410876/is-ubuntus-libsdl2-dev-package-missing-dependencies-or-have-i-made-a-mistake?noredirect=1#comment2451919_1410876
That seemed to confirm that this might be a packaging/dependencies issue.
The downstream report for Ubuntu is here:
https://bugs.launchpad.net/ubuntu/+source/libsdl2/+bug/1976198
Thank you for your time. I hope this feedback is helpful and not just my
misunderstanding.

.
[ Simon McVittie ]
* d/control: Remove Sam Hocevar from Uploaders,
with thanks for past contributions (Closes: #1011583)
* d/tests/installed-tests: Assert that at least one test was run
* d/control: Add missing dependencies for static linking
(Closes: #1012088, LP: #1976198)
* d/tests/cmake: Exercise static linking to SDL
* Standards-Version: 4.6.1 (no changes required)
* Only skip testatomic on Ubuntu, not the rest of the test suite.
This lets us get at least some confidence that the package is working.
