Finding the right Python interpreter in makefile

Sometimes I need to run python from a makefile. This little trick helps me find the python interpreter to use in a cross platform way. Have a file called pyexe.py with the following content:

#!/usr/bin/env python
from sys import executable
print executable

Make sure the file is executable on *NIX world and that there is a .py file association on Microsoft land.

Then in the makefile just write

PYTHON = $(shell pyexe.py)
