makexp_aix
#!/bin/sh
#
# ===========================================================================
# 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).
#
# HISTORY:
# 3-Apr-1998 -- remove C++ entries of the form Class::method
# Vladimir Marangozov
#
# 1-Jul-1996 -- added header information
# Vladimir Marangozov
#
# 28-Jun-1996 -- initial code

# 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
#
# Use -X32_64 if it appears to be implemented in this version of 'nm'.
