# Todo: make recipe compatible with all p4a architectures
'''
.. note:: This recipe can be built only against API 21+ and arch armeabi-v7a
.. versionchanged:: 0.6.0
Rewrote recipe to support clang's build and boost 1.68. The following
changes has been made:
- Bumped version number to 1.2.0
- added python 3 compatibility
- new system to detect/copy generated libraries
