7# Create the export list for perl.
8# Needed by AIX to do dynamic linking.

22c35a8c 10# This simple program relies on global.sym and few other *.sym files
8c3ad6a1
JH
11# and the *var*.h files being up to date with all of the global
12# symbols that a dynamic link library might want to access.

14# Most symbols have a Perl_ or PL_prefix because that's what embed.h
15# sticks in front of them.

17# AIX requires the list of external symbols (variables or functions)
18# that are made available for another executable object file the import.
19# The list is called the export file and it is a simple text file.
20# The first line must be
21#!
22# That is, hash-bang, pound-shout, however you want to call it.
23# The remainder of the file are the names of the symbols, one per line.
24# The file is then given to the system loader (cc/xlc command line)
25# as -bE:export.file.
