I've compiled it successfully on:

Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
Linux AAH 3.13.0-46-generic #75-Ubuntu SMP Tue Feb 10 15:24:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I have successfully compiled this patch on FreeBSD.

This builds on OS X:

Darwin mac.local 15.0.0 Darwin Kernel Version 15.0.0: Wed Aug 26 16:57:32 PDT 2015; root:xnu-3247.1.106~1/RELEASE_X86_64 x86_64

[brucem]

emaste, are you okay with this and willing to approve it?

It looks good to me.

[joerg]

LGTM

[emaste]

Fine by me.

I'm not sure how we ended up with the Python-with-semicolons in scripts/buildSwigWrapperClasses.py (prior to this change) though.

[brucem]

Kamil, please rebase forward and I'll land it.

The semicolons in Python are gone now. And so is the need for that block of Python at all.
