# FILE: ld_so_aix
|
|
# TYPE: executable, uses makexp_aix
|
|
# SYSTEM: AIX
|
|
#
|
|
# DESCRIPTION: Creates a shareable .o from a set of pre-compiled
|
|
# (unshared) .o files
|
|
#
|
|
# USAGE: ld_so_aix [CC] [arguments]
|
|
#
|
|
# ARGUMENTS: Same as for "ld". The following arguments are processed
|
|
# or supplied by this script (those marked with an asterisk
|
|
# can be overriden from command line):
|
|
#
|
|
# Argument Default value
|
|
# (*) -o [OutputFileName] -o shr.o
|
|
# (*) -e [EntryPointLabel] -e init[OutputBaseName]
|
|
# (*) -bE:[ExportFile] -bE:[OutputBaseName].exp
|
|
# (*) -bI:[ImportFile] -bI:./python.exp
|
|
# -bM:[ModuleType] -bM:SRE
|
|
# -bhalt:[Number] -bhalt:4
|
|
# -T[Number] -T512
|
|
# -H[Number] -H512
|
|
# -lm
|
|
#
|
|
# The compiler specific ("-lc" or "-lc_r", "-lpthreads",...)
|
|
# arguments will be automatically passed to "ld" according
|
|
# to the CC command provided as a first argument to this
|
|
# script. Usually, the same CC command was used to produce
|
|
# the pre-compiled .o file(s).
|
|
#
|
|
# NOTES: 1. Since "ld_so_aix" was originally written for building
|
|
# shared modules for the Python interpreter, the -e and
|
|
# -bI default values match Python's conventions. In
|
|
# Python, the entry point for a shared module is based
|
|
# on the module's name (e.g., the "mathmodule" will
|
|
# expect an entry point of "initmath").
|
|
# 2. The script accepts multiple .o or .a input files and
|
|
# creates a single (shared) output file. The export list
|
|
# that is created is based on the output file's basename
|
|
# with the suffix ".exp".
|
|
# 3. The resulting shared object file is left in the
|
|
# current directory.
|
|
# 4. Uncommenting the "echo" lines gives detailed output
|
|
# about the commands executed in the script.
|
|
#

|
|
# HISTORY: Oct-1996 -- Support added for multiple .o files --
|
|
# -- and optional arguments processing. --
|
|
# Chris Myers (myers@tc.cornell.edu), Keith Kwok
|
|
# (kkwok@tc.cornell.edu) and Vladimir Marangozov
|
|
#
|
|
# Aug-6-1996 -- Take care of the compiler specific --
|
|
# -- args by leaving CC to invoke "ld". --
|
|
# Vladimir Marangozov
|
|
#
|
|
# Jul-1-1996 -- Make sure to use /usr/ccs/bin/ld --
|
|
# -- Use makexp_aix for the export list. --
|
|
# Vladimir Marangozov (Vladimir.Marangozov@imag.fr)
|
|
#
|
|
# Manus Hand (mhand@csn.net) -- Initial code -- 6/24/96
