##### Python linking on OS X is tricky ###
|
|
# Confounding problems are:
|
|
# 1) likelyhood of multiple python installs of the same major.minor version
|
|
# because apple supplies python built-in and many users may have installed
|
|
# further versions using macports
|
|
# 2) boost python directly links to a python version
|
|
# 3) the below will directly link _mapnik.so to a python version
|
|
# 4) _mapnik.so must link to the same python lib as boost_python.dylib otherwise
|
|
# python will Abort with a Version Mismatch error.
|
|
# See http://trac.mapnik.org/ticket/453 for the seeds of a better approach
|
|
# for now we offer control over method of direct linking...
|
|
# The default below is to link against the python dylib in the form of
|
|
#/path/to/Python.framework/Python instead of -lpython
|
