Subject: Compiling pwlib on 10.4 (Tiger)
While attempting to compile pwlib (which is required for GnomeMeeting), I get
the following error:
g++3 -DP_MACOSX=810 -DNO_LONG_DOUBLE -D_REENTRANT -Wall -DPHAS_TEMPLATES -I/sw/build/pwlib-1.5.2-12/pwlib/include/ptlib/unix -I/usr/include/pwlib -I/sw/build/pwlib-1.5.2-12/pwlib/include -O2 -DNDEBUG -I/sw/include -fno-common -dynamic -fno-common -dynamic -DPTRACING=1 -x c++ -c ../../ptclib/asner.cxx -o /sw/build/pwlib-1.5.2-12/pwlib/lib/obj_Darwin_ppc_r/asner.o

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:
<newpatch.txt>
That compile then dies with this error:

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:
<newpatch2.txt>
Almost fixed now, but I still get errors which I don't know how to fix:

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:
<newpatch3.txt>
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 lost interest in "blade servers" when I found they didn't throw knives at people who weren't supposed to be in your machine room.
