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 +# ======================================================================== +# + +usage="Usage: ld_so_aix [CC command] [ld arguments]" +if test ! -n "$*"; then + echo $usage; exit 2 +fi + +makexp=`dirname $0`/makexp_aix + +# Check for existence of compiler. +CC=$1; shift +whichcc=`which $CC` + +if test ! -x "$whichcc"; then + echo "ld_so_aix: Compiler '$CC' not found; exiting." + exit 2 +fi + +if test ! -n "$*"; then + echo $usage; exit 2 +fi + +# Default import file for Python +# Can be overriden by providing a -bI: argument. +impfile="./python.exp" + +# Parse arguments +while test -n "$1" +do + case "$1" in + -e | -Wl,-e) + if test -z "$2"; then + echo "ld_so_aix: The -e flag needs a parameter; exiting."; exit 2 + else + shift; entry=$1 + fi + ;; + -e* | -Wl,-e*) + entry=`echo $1 | sed -e "s/-Wl,//" -e "s/-e//"` + ;; + -o) + if test -z "$2"; then + echo "ld_so_aix: The -o flag needs a parameter; exiting."; exit 2 + else + shift; objfile=$1 + fi + ;; + -o*) + objfile=`echo $1 | sed "s/-o//"` + ;; + -bI:* | -Wl,-bI:*) + impfile=`echo $1 | sed -e "s/-Wl,//" -e "s/-bI://"` + ;; + -bE:* | -Wl,-bE:*) + expfile=`echo $1 | sed -e "s/-Wl,//" -e "s/-bE://"` + ;; + *.o | *.a) + objs="$objs $1" + args="$args $1" + ;; + -bM:* | -Wl,-bM:* | -H* | -Wl,-H* | -T* | -Wl,-T* | -lm) + ;; + *) + args="$args $1" + ;; + esac + shift +done + + +if test -z "$objs"; then + echo "ld_so_aix: No input files; exiting." + exit 2 +elif test ! -r "$impfile"; then + echo "ld_so_aix: Import file '$impfile' not found or not readable; exiting." + exit 2 +fi + +# If -o wasn't specified, assume "-o shr.o" +if test -z "$objfile"; then + objfile=shr.o +fi + +filename=`basename $objfile | sed "s/\.[^.]*$//"` + +# If -bE: wasn't specified, assume "-bE:$filename.exp" +if test -z "$expfile"; then + expfile="$filename.exp" +fi + +# Default entry symbol for Python modules = init[modulename] +# Can be overriden by providing a -e argument. +if test -z "$entry"; then + entry=init`echo $filename | sed "s/module.*//"` +fi + +#echo "ld_so_aix: Debug info section" +#echo " -> output file : $objfile" +#echo " -> import file : $impfile" +#echo " -> export file : $expfile" +#echo " -> entry point : $entry" +#echo " -> object files: $objs" +#echo " -> CC arguments: $args" + +CCOPT="-Wl,-e$entry -Wl,-bE:$expfile -Wl,-bI:$impfile -Wl,-bhalt:4" +CCOPT="$CCOPT -Wl,-bM:SRE -Wl,-T512 -Wl,-H512 -lm -o $objfile" +# Note: to use dynamic libraries like libtcl8.4.so and libtk8.4.so +# you may need to replace the second CCOPT line above with the following: +# CCOPT="$CCOPT -Wl,-bM:SRE -Wl,-T512 -Wl,-H512 -brtl -bnortllib -lm -o $objfile" + +CCARGS="$args" + +# Export list generation. +#echo $makexp $expfile "$objfile" $objs +$makexp $expfile "$objfile" $objs + +# Perform the link. +#echo $CC $CCOPT $CCARGS +$CC $CCOPT $CCARGS + +# Delete the module's export list file. +# Comment this line if you need it. +rm -f $expfile
