I sent this message to Shawn Hsiao a few weeks ago, but received no
response, and neither have there have been any updates to pwlib in the
intervening time. Is there anyone else who can help me with this
issue? (I've CC'ed James Gibbs as he is mentioned in DescPackaging as
having packaged Version 1.5.2-10).

Subject: Compiling pwlib on 10.4 (Tiger)
While attempting to compile pwlib (which is required for
GnomeMeeting), I get
the following error:

If I add this patch to /sw/fink/dists/unstable/main/finkinfo/libs/
pwlib.patch,
in addition to the one already there, the compile gets further:

This appears to be where pwlib tries to build its own dlopen/
dlclose/dlsym
functions, instead of using the ones built in to OS 10.4. If I add
this patch
as well, it gets past that error:

Almost fixed now, but I still get errors which I don't know how to

Firstly, does pwlib need to compile its own regex libraries? Could
this be
patched to use the system-distributed ones in the same way I patch
it to use
the system-distributed dlopen/dlsym/dlerror? [2 hours later, after
another
ten minutes of hacking] Here is a patch which does that, and it
appears to
work properly:

Secondly, there are those undefined symbols. Do you know what
those symbols
are? I've been able to demangle the symbols with c++filt, and
here's what I
get:
virtual thunk to std::basic_istream<char, std::char_traits<char>
>::~basic_istream()
I can't quite track down this problem. It appears that it might be
related to
shared libraries and C++ templates, but it's hard to identify.
I'm still stuck on this problem, and I'm totally clue
