# FILE: makexp_aix |
|
# TYPE: standalone executable |
|
# SYSTEM: AIX 3.2.5 and AIX 4 |
|
# |
|
# 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' which produces quite |
|
# different output under AIX 4 than under AIX 3.2.5. |
|
# The following handles both versions by using a common flagset. |
|
# Here are some hidden tricks: |
|
# 1. Use /usr/ccs/bin/nm. Relevant to AIX 3.2.5 which has |
|
# another version under /usr/ucb/bin/nm. |
|
# 2. Use the -B flag to have a standard BSD representation |
|
# of the symbol list on both AIX 3.2.5 and AIX 4. The "-B" |
|
# flag is missing in the AIX 3.2.5 online usage help of 'nm'. |
|
# 3. Use the -x flag to have a hex representation of the symbol |
|
# values. This fills the leading whitespaces on AIX 4, |
|
# thus simplifying the sed statement. |
|
# 4. 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. |
|
# 5. Eliminate entries containing a dot. We can have a dot only |
|
# as a symbol prefix, but such symbols are undefined externs. |
|
# 6. Eliminate everything including the key letter, so that we're |
|
# left with just the symbol name. |
|
# 7. Eliminate all entries containing two colons, like Class::method |
|
# |
