Unresolved Externals

[Andre Louw-2]

Hi,

I have now done the following:

        1) "make clean" on QuantLib
        2) "python setup.py clean" on QuantLib-SWIG/Python
        3) rm -rf `locate QuantLib.so` - this also removed "_QuantLib.so"
        4) rm -rf `locate QuantLib.py`

        5) "make install" on QuantLib
        6) "python setup.py wrap & install" on QuantLib-SWIG/Python

alas, I still get the same unresolved:

>> ImportError: /usr/lib/python2.2/site-packages/QuantLib/_QuantLib.so:
undefined symbol:
>> _ZNK8QuantLib28BlackVolatilityTermStructure17blackVarianceImplEddb

Any other suggestions?

Were QuantLib and QuantLib-SWIG both the latest version from CVS?

Luigi,

I did a CVS update of both projects directly after each other, so I would
assume I have the latest source.

I'm still worried that I might have an old version of something lying around
- please confirm that deleting all QuantLib.so*, _QuantLib.so, QuantLib.py,
QuantLib.pyc files should do the trick?

It should. Maybe a
$ locate QuantLib | grep /usr
would round up some more suspects... also, when you've located your
(hopefully unique) libQuantLib.so,
$ nm /usr/local/lib/libQuantLib.so | grep blackVarianceImpl
(or wherever it's installed if not /usr/local/lib) should tell you whether
the missing external is actually defined.

I am now totally confused. I have only 1 version of libQuantLib.so located
in /usr/local/lib and it _does_ define the missing external. Sorry to be
such a pain but I'm now stumped!

Maybe for some reason it's not finding the library altogether? Try checking
that ld.so.conf contains an entry for /usr/local/lib (the file should be in
/etc), run ldconfig and try again.
