MSVC Unresolved externals

[Andre Louw-2]

Hi,

I have a funny when building the SWIG wrapper on Win32 using the
straightforward 'python setup.py build':

The compile step goes well. When linking it gets a bunch (15) of unresolved
externals:

unresolved externals

If I then go and execute exactly the same link command (copy and pasted from
the shell into a .bat file), these unresolved externals mysteriously
dissapear and the .pyd is fully usable!

Any help appreciated!

My guess is that you're compiling the current CVS version of
QuantLib-Python while linking an older QuantLib library.
Try to update your installed QuantLib version with the current CVS version.

Under Windows you might consider using the QuantLib-Python MS Visual Studio
project, instead of the standard 'setup.py build'. The Visual Studio
project has a few "OnTheEdgeXXX" build configurations that link the
QuantLib version they find in a relative ..\QuantLib path instead of the
installed one.
I use this trick to have a "stable" version of QuantLib installed, while
hacking on the CVS trunk head. The only requirement is to check out all the
CVS modules in the same folder as in:
Projects\QuantLib
Projects\QuantLib-Python
Projects\QuantLib-SWIG
Projects\QuantLibXL
Projects\xlw

Let me know if this solve your problem
