# Create the export list for perl.
|
|
# Needed by AIX to do dynamic linking.
|
|
#
|
|
# This simple program relies on 'global.sym' and few other *.sym files
|
|
# and the *var*.h files being up to date with all of the global
|
|
# symbols that a dynamic link library might want to access.
|
|
#
|
|
# Most symbols have a Perl_ or PL_prefix because that's what embed.h
|
|
# sticks in front of them.
|
|
#
|
|
# AIX requires the list of external symbols (variables or functions)
|
|
# that are made available for another executable object file the import.
|
|
# The list is called the export file and it is a simple text file.
|
|
# The first line must be
|
|
#!
|
|
# That is, hash-bang, pound-shout, however you want to call it.
|
|
# The remainder of the file are the names of the symbols, one per line.
|
|
# The file is then given to the system loader (cc/xlc command line)
|
|
# as -bE:export.file.
