Current evaluation

Snapcraft 2.20 wrapper script omits libunity from LD_LIBRARY_PATH on Launchpad buildd but not locally. No labels, no comments, no maintainer interaction in ~7.6 years. Current desktop extension explicitly adds libunity to LD_LIBRARY_PATH, making the original problem obsolete.

Suggested action: close stale

Reason: The issue targets snapcraft 2.20 (2016) and the wrapper script mechanism has been completely rewritten since then (command-chain, adapters, extensions). The current desktop extension at extensions/desktop/common/desktop-exports explicitly includes 'append_dir LD_LIBRARY_PATH "$SNAP_DESKTOP_RUNTIME/usr/lib/$ARCH/libunity"', directly addressing the libunity path concern. Zero maintainer interaction, no labels, and no activity in 2794 days confirm this is no longer applicable.

Issue body

if built on launchpad buildd, snapcraft does not add $SNAP/usr/lib/x86_64-linux-gnu/libunity to LD_LIBRARY_PATH in the wrapper script. This results in the error: ** (process:28769): WARNING **: Failed to load shared library 'libunity.so.9' referenced by the typelib: libunity-protocol-private.so.0: cannot open shared object file: No such file or directory see: https://bugs.launchpad.net/snappy/+bug/1602845/comments/7 however if you run snapcraft locally everything works: https://bugs.launchpad.net/snappy/+bug/1602845/comments/10 the assumtion that snapcraft is outdated on buildd is not true. As you can see here version 2.20 (latest) is used: https://launchpadlibrarian.net/291705533/buildlog_snap_ubuntu_xenial_arm64_teatime_BUILDING.txt.gz the difference is the following line in the command-teatime.wrapper: -export LD_LIBRARY_PATH="$SNAP/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH" +export LD_LIBRARY_PATH="$SNAP/usr/lib/x86_64-linux-gnu:$SNAP/usr/lib/x86_64-linux-gnu/libunity:$SNAP/usr/lib/x86_64-linux-gnu/pulseaudio:$LD_LIBRARY_PATH"
