The -bM, -bE, -bI, -H, -T, and -lc -# arguments of "ld" will be supplied by this script. -# NOTES: 1. Currently specific to the building of Python -# interpreter shared objects, in that the entry -# point name is hardcoded based on the object file -# name (the "mathmodule.o" file will expect an -# entry point of "initmath"). This could be remedied -# by the support (or simple expectation) of a "-e" -# argument. -# 2. The resulting shared object file is left in the -# current directory with the extension .so. It may -# need to be changed to have a .o extension before -# it is usable. (At least, Python expects it to -# have the .o extension, but this is simply because -# python wants it that way -- it COULD probably be -# called anything at all). -# HISTORY: Manus Hand (mhand@csn.net) -- Initial code -- 6/24/96 -# ======================================================================== - -# ======================================================================== -# SET UP VARIABLES FOR USE IN THIS SCRIPT -# ------------------------------------------------------------------------ -# Note that the setting of "entry" is Python-build specific.

Here is the rule: any "extern" symbol name which -# appears in the # output of "nm" which IS resolved (i.e., which does -# NOT have an address of zero) should go into the export list. Read -# each line from a temp file containing these symbols. If it begins -# with a dot, then add it to the list being built. If it does not, then -# see if the same symbol, with the dot prepended, also appears in the -# list. If so, DON'T include the current symbol (the one without the -# prepended dot). -# ====================================================================== -exec 3>&1 1>$filename.exp -echo "#!$objfile" -nm $objfile | grep "|extern|" | grep -v " 0|extern|" | cut -f1 -d"|" > $tmpfile -while read line ; do - echo "$line" | cut -c1 | read prefix - if [ "$prefix" = "." ]; then - echo "$line" - else - grep "^\.$line" $tmpfile > /dev/null - if [ $? != 0 ]; then - echo "$line" ; fi ; fi ; done < $tmpfile -rm $tmpfile - -# =============================================================== -# IMPORT LIST AND SHARED OBJECT FILE GENERATION -# --------------------------------------------------------------- -# Send all output to the to-be-built import file, starting it off -# with the required "#!" line (which tells it in which loaded -# binary these symbols are to be found at runtime). Then attempt -# to ld the object using only the export list built above, and -# hide the stderr output from "ld". If the ld fails with status -# code 8 (and in the case of the Python modules, it always does, -# since each need some symbols from the statically linked portion -# of the interpreter), this is because an import list should be -# given containing the symbols which are unresolved. The symbols -# will have been sent to stdout as a side-effect of the failed ld -# command, so by redirecting the stdout output, they will have -# magically been put into the import file being built.

As I said, here is the dividing line. Now, -# of course, if there is a module which needs NO statically linked -# symbols -- but then again, there can't be, because they all need -# initmodule4() -- the "ld" which is ABOVE this line may actually -# have succeeded, so the "if" below will fail, but of course, -# if you separate the script at this point, you won't care about -# such things. -# ================================================================ -if [ $status = 8 ] ; then - ld $ldargs $filename.imp ; fi - -# ====================================================================== -# GUIDO: Remember that at this point, the files (assuming you leave the -# arguments to LDSHARED totally unchanged) are still named with a .so -# extension. However, Python looks for them with a .o extension. You -# can either change this in the core code (#ifdef _AIX) so that it looks -# for an .so or you can do what I did, which is rename them to .o's when -# they get mv'ed by the sharedinstall make rule. (Actually, I did it by -# hand, but you'd do it in sharedinstall. -# =======================================================================
