16 * Two directories must be found, the platform independent directory
17 * (prefix), containing the common .py and .pyc files, and the platform
18 * dependent directory (exec_prefix), containing the shared library
19 * modules. Note that prefix and exec_prefix can be the same directory,
22 * Py_GetPath() carries out separate searches for prefix and exec_prefix.
24 * file or directory is found. If no prefix or exec_prefix is found, a
25 * warning message is issued and the preprocessor defined PREFIX and
38 * pathname if one is found) and the directory of the link target is used.
40 * Finally, argv0_path is set to the directory containing the executable
44 * are performed for prefix and for exec_prefix, but with a different
47 * Step 1. Are we running python out of the build directory? This is
49 * argv0_path. For prefix, the landmark's path is derived from the VPATH
54 * For the remaining steps, the prefix landmark will always be
56 * lib/python$VERSION/lib-dynload, where $VERSION is Python's version
58 * build directory checking is performed; if the first step did not find
64 * it points to prefix and exec_prefix. $PYTHONHOME can be a single
65 * directory, which is used for both, or the prefix and exec_prefix
68 * Step 3. Try to find prefix and exec_prefix relative to argv0_path,
70 * step to succeed. Note that if prefix and exec_prefix are different,
72 * subdirectory of prefix, both will be found.
75 * PREFIX and EXEC_PREFIX. These are supplied by the Makefile but can be
80 * Well, almost. Once we have determined prefix and exec_prefix, the
82 * relative path on PYTHONPATH is prefixed with prefix. Then the directory
85 * prefix and exec_prefix globals are tweaked so they reflect the values
87 * off. If either points to the build directory, the globals are reset to
88 * the corresponding preprocessor variables (so sys.prefix will reflect the
90 * directory). This seems to make more sense given that currently the only
91 * known use of sys.prefix and sys.exec_prefix is for the ILU installation
