Use QuantLib Swig Python Extension with VS2010
 
|
Dear all,
I'm trying to compile the python swig extension. Unfortunately this is not working. My current setup looks like this. - QuantLib Version 1.1 - Python Version 2.7.2 - Visual Studio 2010 SP1 When I try to compile the python swig extensions I get the following error: running buildI googled for solutions, but all the indications I found were similar to what I found here: http://slacy.com/blog/2010/09/python-unable-to-find-vcvarsall-bat/ Essentially the problem seems to be: python 2.7 is only "designed" to be compiled with VS2008 (and before) and you can not mix a (pre)compiled python 2.7 with libraries compiled with VS2010. Now, it is not that easy to have an older version of VS installed on my system and in any case I would really prefer to stick with VS2010. The question is: does anybody have a similar setup to mine and was able to compile the python swig extensions? If so, did you have to change things and what exactly has it been? Any help would be very much appreciated. Kind regards, Michael ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Hi Micheal
in order to achieve your goal you should compile Python with VC2010, or Pyhton and QL bindings would never link. Anyway that is definitely not the suggested way to go, as you might discover that also QL is not friendly with VC2010. Try to go back to VC2008. I for one would probably just skip VC2010 altogheter ciao -- Nando On Wed, Jul 4, 2012 at 10:00 PM, Michael <[hidden email]> wrote: > Dear all, > > I'm trying to compile the python swig extension.

By tweaking your environment variables, you can bypass that. You might have issues related to the manifest in you files. I have solved that issue with Cython and some wrappers built under VS2010 lately. I don't know how SWIG behaves though. -- Didrik ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Nando,
I agree with VC2008 being the preferred compiler for the Python module, but what do you mean with "QL is not friendly with VC2010"?

Sure it is. At the very least, the one released in 1.2 works.
