Dear Maintainer,

Currently libdavs2-16 seems not to have any reverse dependency other than
libdavs2-dev. I presume that it has been added to Debian in anticipation of
VLC 4.0 and/or other future reverse dependencies.

So I tried to use it from a custom build of VLC 4.0 and... it is currently
unusable in VLC 4.0 because it requires an executable stack, which Debian's
run-time linker (understandably) appears to refuse to provide:

$ LANGUAGE=C ./vlc -v
VLC media player 4.0.0-dev Otto Chriek (revision 4.0.0-dev-34776-g90a6f422e1)
[00007cb280de0040] main libvlc warning: cannot read /home/remi/videolan/vlc/build/modules/plugins/plugins.dat: No such file or directory
[00007be27f95ed20] main generic error: cannot load plug-in /home/remi/videolan/vlc/build/modules/.libs/libdavs2_plugin.so: libdavs2.so.16: cannot enable executable stack as shared object requires: Invalid argument

Fortunately VLC just ignores the faulty plugin and moves on, but this begs
the question whether there is any reasonable way to use libdavs2.so in Debian?

Hi Rémi,

davs2 was removed from Debian (all suites) over a year ago. See
#1075984.

Cheers
