problem with Python Bindings for QuantLib
 
|
Hi,
I hope someone can help me with this: I've got a problem building the Python Bindings for QuantLib, I get stack in the build process... I have tried to follow the instructions I had found on another site: http://www.wilmott.com/messageview.cfm?catid=10&threadid=34537
However I'm running into trouble, most likely due to some compiler versions incompatibility.
If I just type:
then I have the following error messages (truncated): C:\build_ql_1_0_1\QuantLib-SWIG-1.0\Python>python setup.py build
running build running build_py
running build_ext building 'QuantLib._QuantLib' extension

QuantLib/quantlib_wrap.cpp:3826: error: `QuantLib' has not been declared After having guessed that probably distutils was not happy because it was not using the same compiler with which I built QuantLib (VC 9.0) I tried to type this:
but had no better luck: C:\build_ql_1_0_1\QuantLib-SWIG-1.0\Python>python setup.py build --compiler=msvc
running build running build_py
running build_ext warning: unable to detect QuantLib installation
error: Python was built with Visual Studio 2003; extensions must be built with a compiler than can generate compatible binaries.
Visual Studio 2003 was not found on this system. If you have Cygwin installed, you can try compiling with MingW32, by passing "-c mingw32" to setup.py.
Stepping through the python code for distutils, I realized that there is some kind of incompatibility with the Microsoft SDK versions. Indeed distutils (I use Python 2.5 from a PythonXY distribution) expects to work with SDK 1.1, but my SDK is 2.0. I actually also happen to have Visual Studio 8 on my computer -along with Visual Studio 9 and also 6- and for some reason distutils seems to pick VStudio 8 as default Microsoft compiler.
Could anyone please help me fixing this issue or suggest an alternative way to use Python with QuantLib? Isn't there any pre-compiled Python Bindings available? Many thanks in advance.

No luck. If you're using Python2.5, it expects VC++7. Is there any chance you can upgrade to Python 2.6 or 2.7?

Thanks Luigi,
I'm pretty much tied to Python 2.5, as it is part of the PythonXY distribution I'm currently using (not the latest one, but I can't upgrade to the newest since there are some incompatibilities between Matplotlib and PyXll, which I'm also using). Although I use Python quite a lot I'm not a Python wizard, especially when it comes to setting up the different distributions and packages.
I would like to start using the Python bindings of QuantLib along with my Python code, but so far it looks like it is not that straightforward. Thanks all the same. LM 2011/2/23 Luigi Ballabio <[hidden email]>
