The libtool link doesn't fail. The failure comes when Python tries to
dlopen the resulting module.
Here's the libtool link line (from the output from "make"):
/bin/sh ../libtool --tag=CXX --mode=link g++ -Wall -Wno-unused
-Wno-uninitialized -g -I/home/olly/install/include -o _xapian.la -rpath
/usr/local/lib/python2.3/site-packages -avoid-version -module -no-undefined
xapian_wrap.lo /home/olly/install/lib/libxapian.la
rm -fr .libs/_xapian.la .libs/_xapian.lai .libs/_xapian.so
g++ -shared -fPIC -DPIC .libs/xapian_wrap.o -L/home/olly/install/lib
-lxapian -o .libs/_xapian.so
creating _xapian.la
(cd .libs && rm -f _xapian.la && ln -s ../_xapian.la _xapian.la)
And here's the error when Python tries to load it:
$ PYTHONPATH=/home/olly/xb-install-tmp:. python -c 'import xapian'
python:/usr/local/lib/libxapian.so.8.0: undefined symbol '_ZTISi'
python: /usr/local/lib/libxapian.so.8.0: can't resolve reference '_ZTISi'
python:/usr/local/lib/libxapian.so.8.0: undefined symbol '_ZTISi'
python: /usr/local/lib/libxapian.so.8.0: can't resolve reference '_ZTISi'
python:/usr/local/lib/libxapian.so.8.0: undefined symbol '_ZTISi'
python: /usr/local/lib/libxapian.so.8.0: can't resolve reference '_ZTISi'
python:/usr/local/lib/libxapian.so.8.0: undefined symbol '_ZNSiD1Ev'
python: /usr/local/lib/libxapian.so.8.0: can't resolve reference '_ZNSiD1Ev'
[And lots more!]
Demangling with c++filt, "_ZTISi" is "typeinfo for std::basic_istream<char,
std::char_traits<char> >". The other symbols are all C++ STL stuff too
from what I could see.
Cheers,
Olly
