# 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. The following changes has
been made:
- Bumped version number to 1.68.0
- Better version handling for url
- Added python 3 compatibility
- Default compiler for ndk's toolchain set to clang
- Python version will be detected via user-config.jam
- Changed stl's lib from ``gnustl_shared`` to ``c++_shared``
