To # install modules, copy them to $(pythondir), using the python_PYTHON # automake variable. To install a package with the same name as the # automake package, install to $(pkgpythondir), or use the # pkgpython_PYTHON automake variable. # The variables $(pyexecdir) and $(pkgpyexecdir) are provided as # locations to install python extension modules (shared libraries). # Another macro is required to find the appropriate flags to compile # extension modules. # If your package is configured with a different prefix to python, # users will have to add the install directory to the PYTHONPATH # environment variable, or create a .pth file (see the python # documentation for details). # If the MINIMUM-VERSION argument is passed, AM_PATH_PYTHON will # cause an error if the version of python installed on the system # doesn't meet the requirement. MINIMUM-VERSION should consist of # numbers and dots only. AC_DEFUN([AM_PATH_PYTHON], [ dnl Find a Python interpreter.
