Hi, Any luck with this problem? I've looked a bit more into it, and it does seem like there is a problem with the Microsoft compiler finding the IPython headers. It could also be in the 'sconstruct' script for relax used by scons to build the C module. You can see this in the relax_fit() method. Maybe it would be worth trying the following within IPython:
>>> import sys >>> import path >>> print sys.prefix + path.sep + 'include' The check that the Python.h file is present in the directory that this prints out. This is the logic used in the script to determine where the header files are. It could be that we have to come up with a special hack for this relax_fit() method to handle IPython on Windows. I hope this info helps. Regards, Edward On 9 May 2013 22:20, Edward d'Auvergne <[email protected]> wrote: > Hi, > > Sorry, I didn't get a chance to look at this problem today.
