RE: Python question

Hi, I am having difficult building the Quantlib-Python from the CVS
download by
doing "python setup.py build " on the command line.
I have Visual C++ 7.1 and the python2.4 is in cygwin environment. Thanks
a lot!

Thanks so much! I will give it a try.

Now I have successfully built the libQuantLib and libQuantLibFunctions
(though failed
at "TestSuite" part) in cygwin environment. However, I still have
trouble with building
the python part: mainly because "quantlib-config: not found". Thanks
again for the
generous help!

You should run 'make install' in the QuantLib directory. It should
install quantlib-config in /usr/local/bin. Make sure it is in your PATH
variable.

It seems like it doesn't find your Boost installation. Try

CXXFLAGS='-I/path/to/boost' python setup.py build

Later,

Thanks! The "run 'make install'" didn't put the file there --- so I did
it manually.
I modified the quantlib-config to include boost path.
It also seems necessary to modify the following lines in the file:
--libs)
echo -L${exec_prefix}/lib -lQuantLib
# echo -L${exec_prefix}/lib -lQuantLib-0.3.10
i.e. removing the version number.

Strange...

Hmm. On my Linux box, 'make install' installs both
libQuantLib-0.3.10.so and libQuantLib.so (the latter being a symbolic
link to the former.) It might be a Cygwin glitch. Is there any Cygwin
user out there knowledgeable on these issues?

Thanks,
Luigi

Hi,

At first glance it strikes me that you're using Cygwin Python (probably
built with GCC 3.3 or so) and trying to compile a Python extension using
Visual C++.
Python extensions need to be compiled with the same compiler that the
Python executable was compiled with.

You could just try to compile QuantLib using gcc from Cygwin Bash.

Hope that helps.
