The failure is only reproducible when linking libsmbclient with -Wl,-z,defs
(or equivalent). We have a patch in the Debian package which does this.
The failure is still an upstream issue, we just have the extra flag set so
that this is handled as a build-time failure instead of a run-time failure.
You can still see the problem on a Linux system by running 'ldd -d -r
/path/to/libsmbclient.so' on a resulting build; those undefined symbols will
cause libsmbclient to fail to load at run time, unless the calling
application happens to already be linked against libz.
It would be good to make this flag an upstream default when linking shared
libraries (as opposed to "DSO"s) - that probably means splitting out
separate SHLD_DSO and SHLD_LIB (?) variables in configure.in/Makefile.in.
Steve Langasek Give me a lever long enough and a Free OS
Debian Developer to set it on, and I can move the world.
