Linking CXX executable ../Cytopia fails on Debian 10 GNU/Linux and Ubuntu WSL due to conan sdl2 not finding libsdlio
Steps to reproduce
- Download or git clone version 1c150858dd1a908eafa9314dbb0b27bd8edb5279 into a directory assumed to be
~/src/Cytopia - Create a fresh build directory and configure it with:
SUDO_ASKPASS=/usr/bin/ssh-askpass cmake ~/src/Cytopia/ - Run
make
Result
Build fails with:

More information
The build error shows that conan's libSDL2 fails to link to libsndio. This may be due to conan's packaging of sdl2 itself or its dependencies, because libsndio-dev is locally installed and linking to it the full path /usr/lib/x86_64-linux-gnu/libsndio.so is preferred by conan by pkg-config sdl2.pc and sdl2-config:

So it's not clear why conan's libSDL2.a fails to link to sndio.
I think that at this point, we should simply disable it. We are not using SDL for playing audio anyway. As far as I know, sndio is also used by openal, so we still support but just not through SDL. It seems that other people have encountered this issue before:
- with openal
- with sdl2 1 2
As you said it's likely to be an issue with the conanfile that we are using from bincrafters. My guess is adding
-DSNDIO_SHARED=ONas cmake option for debian/ubuntu builds would resolve this issue. However I do not know if the conanfile we are using is even being maintained anymore (I couldn't find any tags or branches in the directory). This might be a hint that we should fork it and maintain it ourselves in conan-packages, but if we are able to just disable it for now, this is too low priority
For what it's worth, it looks like CMake doesn't recognize that particular SNDIO_SHARED option indicated by "Manually-specified variables were not used by the project" in the output below, and so the build still fails in the same way. Though quite possibly I'm specifying the option at the wrong place and it's not propagating to the conan subproject?

Oh I meant the SNDIO_SHARED option should be passed to CMake while building SDL2. Cytopia doesn't support that directly. We would need a conan option and add it to /conanfile-linux.txt.in. I think this option was added for a later version than we are using (SDL 2.0.14) and it not really supported for earlier versions. We would have to update SDL in Cytopia but we've encountered other issues while trying that in the past. Perhaps this is proof that we can no longer rely on bincrafters as a source for SDL
I have tried with the following conan options to see if it would automatically remove the dependency on sndio and I upgraded to 2.0.14, but it didn't work for me.
sdl2:nas=False
sdl2:alsa=False
sdl2:jack=False
sdl2:pulse=False
sdl2:esd=False
*** Could not run SDL test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding SDL or finding the wrong
*** version of SDL. If it is not finding SDL, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that
*** is required on your system
***
*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
It should still be possible to build on debian without conan at this point by using the -DPACKAGE_MANAGER=pkgconfig given you have pkgconfig installed and all the dependencies are present. Or you could also use -DPACKAGE_MANAGER=none but you will need to add a bunch of cache variables (either through CMake GUI or editing CMakeCache.txt manually) to point to where your dependencies are. However, we should definitely fix the conan build for debian
