| 3 | # Convert templates into Makefile and config.c, based on the module |
| 4 | # definitions found in the file Setup. |
| 5 | # |
| 6 | # Usage: makesetup [-s dir] [-c file] [-m file] [Setup] ... [-n [Setup] ...] |
| 7 | # |
| 8 | # Options: |
| 9 | # -s directory: alternative source directory (default .) |
| 10 | # -l directory: library source directory (default derived from $0) |
| 11 | # -c file: alternative config.c template (default $libdir/config.c.in) |
| 12 | # -c -: don't write config.c |
| 13 | # -m file: alternative Makefile template (default ./Makefile.pre) |
| 14 | # -m -: don't write Makefile |
| 15 | # |
| 16 | # Remaining arguments are one or more Setup files (default ./Setup). |
| 17 | # Setup files after a -n option are used for their variables, modules |
| 18 | # and libraries but not for their .o files. |
| 19 | # |
| 20 | # See Setup for a description of the format of the Setup file. |
| 21 | # |
| 22 | # The following edits are made: |
| 23 | # |
| 24 | # Copying config.c.in to config.c: |
| 25 | # - insert an identifying comment at the start |
| 26 | # - for each <module> mentioned in Setup before *noconfig*: |
| 27 | # + insert 'extern PyObject* PyInit_<module>(void);' before MARKER 1 |
| 28 | # + insert '{"<module>", PyInit_<module>},' before MARKER 2 |
| 29 | # |
| 30 | # Copying Makefile.pre to Makefile: |
| 31 | # - insert an identifying comment at the start |
| 32 | # - replace _MODBUILT_NAMES_ by the list of *static* and *shared* modules |
| 33 | # from Setup |
| 34 | # - replace _MODDISABLED_NAMES_ by the list of *disabled* modules from Setup |
| 35 | # - replace _MODOBJS_ by the list of objects from Setup (except for |
| 36 | # Setup files after a -n option) |
| 37 | # - replace _MODLIBS_ by the list of libraries from Setup |
| 38 | # - for each object file mentioned in Setup, append a rule |
| 39 | # '<file>.o: <file>.c; <build commands>' to the end of the Makefile |
| 40 | # - for each module mentioned in Setup, append a rule |
| 41 | # which creates a shared library version to the end of the Makefile |
| 42 | # - for each variable definition found in Setup, insert the definition |
| 43 | # before the comment 'Definitions added by makesetup' |
| 44 | |
| 45 | # Loop over command line options |
