# FILE: defmakexp_aix
|
||||
# TYPE: standalone executable
|
||||
# SYSTEM: AIX, Solaris
|
||||
#
|
||||
# DESCRIPTION: This script creates the default export list file "python.exp"
|
||||
# for AIX platforms which has to be included in the Modules
|
||||
# directory of the python source tree.
|
||||
# It contains all global symbols defined in the following files:
|
||||
# a) main.o config.o getpath.o
|
||||
# b) libModules.a libPython.a libObjects.a libParser.a
|
||||
#
|
||||
# The script should be run after a new unpack, configure & make
|
||||
# of the python release, without any options nor changes to
|
||||
# Modules/Setup.in (i.e. a default static build).
|
||||
#
|
||||
# USAGE: defmakexp_aix [path]
|
||||
#
|
||||
# where [path] points to the Python source root directory.
