7 | # Create the export list for perl. |
8 | # Needed by AIX to do dynamic linking. | |
71be2cbc | 9 | # |
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. | |
71be2cbc | 13 | # |
8c3ad6a1 JH |
14 | # Most symbols have a Perl_ or PL_prefix because that's what embed.h |
15 | # sticks in front of them. | |

8c3ad6a1 JH |
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. | |
