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...
With VC 7.1, you can just enter the QuantLib-SWIG\Python directory, open a command shell, and type:
set QL_DIR=V:\somewhere\QuantLib (replace with the directory where you saved and compiled QuantLib)
python setup.py build test
If everything works, run
python setup.py install
and you're ready. |

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

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:
python setup.py build --compiler=msvc |
|
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.
