Re: [SciPy-Dev] cubature license
@Alex, you are right, "it uses some GPL code from other projects (Hintlib and GSL). " But is it really impossible to include it in SciPy because of that? Saullo 2013/8/24 <scipy-dev-request@scipy.org>

Dear all,
I already contacted Steven Johnson about this matter and he told me that "relicensing the Cubature code is not feasible", but he agrees on including this in SciPy if the SciPy community agrees to include a GNU GPL licensed software there.
Otherwise I will probably create a separate Python package for it, ideally with a pip installer, as suggested by him.

I noticed on the mailing list that someone wants to put cubature into scipy. You will need to ask Steven Johnson before this can happen because scipy is licensed in a way that does not allow it to accept GPL code. Actually now that I read more, this will probably not happen anyway because cubature itself depends on multiple GPL-licensed codes. http://mail.scipy.org/pipermail/scipy-dev/2013-August/thread.html http://ab-initio.mit.edu/wiki/index.php/Cubature

I took a number of his classes at MIT, and I'm fairly sure he'd be on board with this usage. He seemed pretty supportive of SciPy.

Yes. We do not include GPL-licensed code in SciPy. I haven't looked at the Cubature code, so I don't know the extent to which it uses HIntLib and GSL, but based on the comment on the web page, it is unlikely that Steven Johnson can re-license his code with a license that is compatible with SciPy. The GPL is viral that way (insert the usual "I am not a lawyer" disclaimer here). But don't let that stop you from creating a python wrapper as a separate project. That's a great idea, and I'm sure a lot of folks will appreciate it. Warren

It's not quite as viral as that. He can license the code that he himself wrote under whatever license he likes as long as it is compatible with the GPL license of the other libraries that he is combining his code with. If the code that he wrote is separable from HIntLib and GSL by rewriting that functionality, he can distribute his code under the BSD license for inclusion in SciPy. -- Robert Kern
