This fixes a bug in the Windows installer where the path to python.exe on the
machine where the installer is built is used, and also allows us generate
different shebang lines for the Python 2 and Python 3 modules.
Fixes Issue 247.
3to2 cannot be called as an executable on Windows, but it can be called
as a script. Assume that the 3to2 script is installed in
PYTHONROOT\Scripts, which is the default for installation by pip.
Some calls to the print function weren't being converted to print statements
correctly by 3to2, so now we use the alternative fix, which is to use the
backported print function.
Fixes Issue 216.
Fixes issues with mismatched compilers between the Cython extension and the
cantera library, especially on OS X. Improves build dependency resolution to
eliminate unnecessary recompilation of _cantera.cpp.
This fixes an issue when the Python interpreter prints startup messages that
appear before the expected output lines. Known to be a problem with the Anaconda
Python distribution.
In particular, this fixes paths for Linux distros that put Python modules in
'lib64/pythonX.Y/site-packages'.
Also fixes the reported installation path for the Python module on Windows.
Setting the scons options 'python_prefix=USER' or 'python3_prefix=USER' will
pass the '--user' flag to setup.py, causing the Python module to be installed to
a platform-specific directory on the user's module path.
This includes automatic conversion of the samples from Python 3 syntax to Python
2 syntax when building the Python 2 version of the module and the "3to2" script
is available.
