Details

Description:
after botan upgrade to 2.9.0, the dependence of shadowsocks-qt5 "libbotan-2.so.8" change to "libbotan-2.so.9"

start ss-qt5 with error message "ss-qt5: error while loading shared libraries: libbotan-2.so.8: cannot open shared object file: No such file or directory"

downgrade botan-2.8.0-2 solved this problem

so maybe we should rebuild shadowsocks-qt5 to resolve this dependence problem

Additional info:
* package version(s) botan-2.9.0-1 shadowsocks-qt5-3.0.1-1
* config and/or log files etc.


Steps to reproduce:
upgrade system with botan-2.9.0-1 shadowsocks-qt5-3.0.1-1
run ss-qt5
   shadowsocks.png (51.2 KiB)

No, that's the wrong package. Please do NOT simply blame the binary when something breaks -- dependencies are resolved recursively, and you need a tool like lddtree (from pax-utils) to tell you where the actual breakage is.

$ pkg-list-linked-libraries shadowsocks-qt5 libbotan
==> checking linked libraries for shadowsocks-qt5-3.0.1-1-x86_64.pkg.tar.xz ...
==> ERROR: No file in shadowsocks-qt5-3.0.1-1-x86_64.pkg.tar.xz is linked to libbotan
$ pkg-list-linked-libraries libqtshadowsocks libbotan
==> checking linked libraries for libqtshadowsocks-2.1.0-4-x86_64.pkg.tar.xz ...
/usr/lib/libQtShadowsocks.so.2.1.0
NEEDED libbotan-2.so.8

That being said, it's still a real issue with a repo package (also maintained by Felix).

In fact, it's an issue with several packages, and ultimately with botan being pushed to community with a changed soname but without rebuilding dependent packages.

@xyproto, why did this not go through staging? `checkpkg` should have warned that the package update came with a changed soname.

- multiple packages to rebuild, libqtshadowsocks is not enough
- qca in extra needs rebuilding too

Sorry to close the issue too early. I just did the rebuild only for libqtshadowsocks 2.1.0-5
