If you're trying to use the release 0.1.1 you don't need to use Swig, since
the wrapper files are already included and ready to be compiled.
This should also be true if you're trying to compile the latest CVS
snapshot: anyway in this case it may happen that wrapper files are out of
Of course if you want to actively develop QuantLib using Python (or
scripting languages) it is useful to have Swig.
In this case please note that we're using 1.3a5. Since the NT port is not
available yet you have to use CygWin.
Follow these steps:
a) Download Cygwin from http://cygwin.com/ and install it. Take note of
your CygWin root (C:\cygwin from now on)
b) Download SWIG1.3a5 from
http://download.sourceforge.net/swig/swig1.3a5.tar.gz c) Copy the file swig1.3a5.tar.gz in a directory under the control of
Cygwin (e.g. your home dir C:\cygwin\home\username)
d) Open a Cygwin shell
> cd "the directory where swig1.3a5.tar.gz is"
> gunzip swig1.3a5.tar.gz
> tar xvf swig1.3a5.tar
> cd SWIG1.3a5
edit "./Makefile" and replace "SWIG_LIB = $(prefix)/lib/swig1.3"
with "SWIG_LIB = $(prefix)/lib/swig1.3a5"
edit "./Source/Include/swigconfig.h" and replace
#define SWIG_LIB "/usr/local/lib/swig1.3"
with #define SWIG_LIB "/usr/local/lib/swig1.3a5"
> make install
> mv /usr/local/bin/swig.exe /usr/local/bin/swig1.3a5.exe
e) Include "C:\cygwin\usr\local\bin" and the path where you have the
cygwin1.dll file ("C:\cygwin\bin") in your system variable $PATH
now you're ready to compile QuantLib.
Borland compiler: use the makefile provided (you will have to change a
couple of defines accordingly to your Python installation).
MSVC compiler: use QuantLib\Win\PyWrap.bat to generate the wrappers. You
will have to add the directory of Python.h to your MSVC settings

This is a problem related with your Swig installation. See my suggestion
for Borland and MSVC
We have changed a few things to have an easier Windows installation. They
will be available this week with release 0.1.2
I will also add a FAQ entry for CygWin/Swig
