Defect #14673
closedMissing shared library dependencies in the installer packages under Linux
0%
Description
I installed BrainVISA using the installer under Arch Linux (brainvisa_installer-4.5.0-linux64-glibc-2.15-online), and I get missing shared libraries when launching BrainVISA:
ImportError: libaudio.so.2: cannot open shared object file: No such file or directory
As this dependency does not seem to be very useful anyway (audio in BrainVISA?) maybe there is some way of avoiding it? I know that passing the flag -Wl,--as-needed can avoid adding unused libraries as dependencies.
I made a small script to list the shared library dependencies that are not present in the packages:
PACKAGE_DIR=/home/yleprince/brainvisa/pkg-4.5.0
LD_LIBRARY_PATH="$PACKAGE_DIR/lib" find "$PACKAGE_DIR" -name '*.so' -exec ldd {} \; > libs.txt
LD_LIBRARY_PATH="$PACKAGE_DIR/lib" find "$PACKAGE_DIR/bin/real-bin" -execdir ldd {} \; > execs.txt
grep -vhF "$PACKAGE_DIR" libs.txt execs.txt | sed 's/ (0x[0-9a-f]\+)$//' | sort | uniq
The results for my system follow. Many of these libraries are probably best kept as dependencies, but it could be useful to bundle those that are really needed, and not present everywhere?

For libaudio, anatomist may make some kind of sound (in a very very non-needed part...) so when it is built with, it is a required dependency. So the best is probably that I remove it or load dynamically libaudio in anatomist.
For other libs, the situation is often not so clear:- some may depend on the system, on hardware, drivers etc like libGL, so this one must normally not be shipped with brainvisa
- many of other missing libs are ony used in some python modules that we are not using at all. As python provides links to many C libs, and generally to almost all of the system, the full dependencies of python would be, more or less, a whole linux system. We don't really want to package libs we are not using (many of them are big)... The "real" problem here is that we ship python as a single package instead of hundreds of different ones like on most linux distribs. But it's too much work to split it into so many pieces and dependencies...

Actually Qt is already linked against libaudio, so it's a required dependency of Qt:
ldd /usr/lib/x86_64-linux-gnu/libQtGui.so.4 | fgrep audio
libaudio.so.2 => /usr/lib/x86_64-linux-gnu/libaudio.so.2 (0x00007fecacc26000)
It's strange that libaudio is not installed on some systems...

Well, libaudio is not a general-purpose audio library, but it is only used for some weird network-based audio setups, so I guess that is why it is not installed on many systems.
The problem with libaudio is that it isn’t even packaged on some distributions (including Arch and Gentoo), so that we cannot simply tell the user to install the relevant package. Then, I see two possible solutions for addressing this problem:- Quick, sub-optimal solution: package libaudio.so.2 with the Qt libraries;
- More involved solution: ship a version of Qt that only has useful features enabled, however this means that we cannot simply use the Debian/Ubuntu package but probably have to compile it from source…

The problem with libaudio is that it isn’t even packaged on some distributions (including Arch and Gentoo),
So How does Qt work on such distributions ? Without audio support ?
Moreover libaudio has neither cmake config nor pkg-config setup, so we will have to do it on our own.
I still prefer solution 1 because when possible we ship the Qt lib of the system we build on, it allows system compatibility for the same system, and avoids the work of rebuilding Qt with all fancy options. And then we ship a full-featured Qt.
By the way, I think the Mandriva-based distrib of Brainvisa doesn't have this audio support/dependency.
Updated by Leprince, Yann about 8 years ago
Yes, it probably supports audio through other libraries, only not the esoteric network-based setup of libaudio…
By the way, I hit another missing library on my Arch system: libtinfo.so.5. It is required by the packaged version of libreadline.so.6, which is itself needed by the shell (system bash); as a result all shell scripts fail to run when LD_LIBRARY_PATH points to the package’s lib/ directory.
The situation with libtinfo is a little different compared to libaudio: this library is part of the ncurses library, but there is the option to build it separately during ncurses configuration. While Debian chose to separate the library, Arch chose not to so it does not exist on this distribution. Gentoo provides a choice, but even when libtinfo is there the shell fails with undefined symbol: rl_signal_event_hook. Life is hard… In the meantime I installed an Ubuntu virtual machine to run BrainVISA on my Arch workstation.
So I guess that for this case the right thing would be to include libtinfo.so.5 in the package that already distributes libreadline?
