# AM_PATH_PYTHON2([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
|
|
# ---------------------------------------------------------------------------
|
|
# Adds support for distributing Python modules and packages. 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_PYTHON2 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.
|
|
#
|
|
# AM_PATH_PYTHON2 is based on AM_PATH_PYTHON but will search only
|
|
# Python 2 locations.
