Hello
To help packages like Apache which have some parts like libaprutil
that wants to link against libmysqlclient16_r.so and some like PHP
that wants to link against libmysqlcient.so, it was proposed that
libmysqlclient.so should be made a symlink pointing to the thread safe
*_r.so version.
(This change would be introduced for the upcoming new soname version
which is not yet into unstable! Performance issues were considered to
be negligible as the client library only copies data from and to the
server)
But when putting a corresponding symlink into
debian/libmysqlclient16.links, the build process fails with:
dh_shlibdeps -a -l debian/libmysqlclient16/usr/lib -L libmysqlclient16

dh_shlibdeps: dpkg-shlibdeps returned exit code 2
make: *** [binary-arch] Error 1
Before I start looking for a creative workaround - is this approach a good idea
in the first place?
Does someone now if binaries build against the shared library on a different
Linux distribution would run on Debian then?
thanks,
