Hi!

In many linux distributions there is a soft link to the numpy-include in the Python include directory (the latter is given by distutils.sysconfig.get_python_inc() or by the python-config command line tool).
However, this soft link does not always exist.
E.g. on our compute clusters we provide several different versions of numpy using a modules system, and to get the location of the numpy include files one could e.g. get it through numpy.get_include().

Just as an illustration, I created a simple patch witch adds both include locations to PYTHON_CPPFLAGS (I'll try to attach it to this thread)

(Hmm, the webform says "The extension patch is not allowed.", .txt doesn't seem to work either. Nevermind, I'll put it in the message instead)
So, this is not a suggested implementation, it is just to illustrate what I mean

Hi Don,

thanks for the suggestion. I will bring it to the attention of the authorities before 6.6 is frozen (hopefully).

Cheers

OK, included in forthcoming v6.6.0 and later !
