    python: Use explicit integer divisions
    In Python 2, divisions of integers return an integer:
        >>> 32 / 4
    In Python 3 though, they return floats:
        >>> 32 / 4
    However, Python 3 has an explicit integer division operator:
        >>> 32 // 4
    That operator exists on Python >= 2.2, so let's use it everywhere to
    make the scripts compatible with both Python 2 and 3.
    In addition, using __future__.division tells Python 2 to behave the same
    way as Python 3, which helps ensure the scripts produce the same output
    in both versions of Python.

Comment 1 Dylan Baker 2018-08-14 16:08:03 UTC
Scons doesn't check that mako is at least 0.8.0 like autotools does (which was released in 2013, btw). The real bug here is that scons doesn't do proper checks like it should.
Comment 2 Emil Velikov 2018-12-07 15:54:02 UTC
Should be fixed with the following commit. Feel free to reopen otherwise.
