# 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'.
