# FILE: ld_so_aix
|
|
# TYPE: executable, uses makexp_aix
|
|
# SYSTEM: AIX
|
|
#
|
|
# DESCRIPTION: Creates a shareable .o from a pre-compiled (unshared)
|
|
# .o file
|
|
#
|
|
# USAGE: ld_so_aix [CC] [arguments]
|
|
#
|
|
# ARGUMENTS: Same as for "ld". The -bM, -bE, -bI, -H, -T, and -lm
|
|
# arguments will be supplied by this script. The compiler
|
|
# specific ("-lc" or "-lc_r", "-lpthreads", etc) 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.
|
|
#
|
|
# 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
|
|
# 3. Uncommenting the "echo" lines gives detailed output
|
|
# about the commands executed in the script.
