Re: boost+python

[Alois Schlögl]

Dear Fedja,


the support for python is not in a usable state. It is a collection of
patches I found some time ago, but never got it working. Currently, this
python support in my repo is unmaintained. Sorry for the news. Feel free
to work on these, as I'd like to see python support on mxe as well.


Cheers,

  Alois
