| # 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 overridden 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 |
