Bug#959201: Acknowledgement (jami-daemon: dring does not start due to a symbol lookup error)

[Bruno Kleinert]

Hi,

the cause seems to be an ABI change in /usr/lib/x86_64-linux-
gnu/libyaml-cpp.so.0.6.3 in package libyaml-cpp0.6 between versions
0.6.2-4 and 0.6.3-1:

While 0.6.2-4 exported
000000000006bd60 B _ZN4YAML6detail9node_data12empty_scalarB5cxx11E

0.6.3-1 now exports
0000000000029af0 T _ZN4YAML6detail9node_data12empty_scalarB5cxx11Ev


I looked at the symbols which dring needs:

20190215.1.f152c98~ds1-1+b1 looks for the one exported by 0.6.2-4 of
libyaml-cpp0.6
00000000004ee180 B _ZN4YAML6detail9node_data12empty_scalarB5cxx11E

After recompilation against libyaml-cpp0.6 0.6.3-1 it looks like this:
                 U _ZN4YAML6detail9node_data12empty_scalarB5cxx11Ev

If I understand this correctly, the upload of libyaml-cpp0.6 lacks a
bump of the SO name to reflect the ABI change and this bug has to be
forwarded to libyaml-cpp0.6.

Cheers,
Bruno
