| # FILE: makexp_aix | |
| # TYPE: standalone executable | |
| # SYSTEM: AIX | |
| # | |
| # DESCRIPTION: This script creates an export list of ALL global symbols | |
| # from a list of object or archive files. | |
| # | |
| # USAGE: makexp_aix <OutputFile> "<FirstLine>" <InputFile> ... | |
| # | |
| # where: | |
| # <OutputFile> is the target export list filename. | |
| # <FirstLine> is the path/file string to be appended | |
| # after the "#!" symbols in the first line of the | |
| # export file. Passing "" means deferred resolution. | |
| # <InputFile> is an object (.o) or an archive file (.a). | |
| # | |

| # Extract the symbol list using 'nm' | |
| # Here are some hidden tricks: | |
| # - Use the -B flag to have a standard BSD representation | |
| # of the symbol list. | |
| # - Use the -x flag to have a hex representation of the symbol | |
| # values. This fills the leading whitespaces, thus simplifying | |
| # the sed statement. | |
| # - Eliminate all entries except those with either "B", "D" | |
| # or "T" key letters. We are interested only in the global | |
| # (extern) BSS, DATA and TEXT symbols. With the same statement | |
| # we eliminate object member lines relevant to AIX 4. | |
| # - Eliminate entries containing a dot. We can have a dot only | |
| # as a symbol prefix, but such symbols are undefined externs. | |
| # - Eliminate everything including the key letter, so that we're | |
| # left with just the symbol name. | |
| # - Eliminate all entries containing two colons, like Class::method | |
