#
Convert templates into Makefile and config.c, based on the module
#
definitions found in the file Setup.
#
#
Usage: makesetup [-s dir] [-c file] [-m file] [Setup] ... [-n [Setup] ...]
#
#
Options:
#
-s directory: alternative source directory (default .)
#
-l directory: library source directory (default derived from $0)
#
-c file: alternative config.c template (default $libdir/config.c.in)
#
-c -: don't write config.c
#
-m file: alternative Makefile template (default ./Makefile.pre)
#
-m -: don't write Makefile
#
#
Remaining arguments are one or more Setup files (default ./Setup).
#
Setup files after a -n option are used for their variables, modules
#
and libraries but not for their .o files.
#
#
See Setup for a description of the format of the Setup file.
#
#
The following edits are made:
#
#
Copying config.c.in to config.c:
#
- insert an identifying comment at the start
#
- for each <module> mentioned in Setup before *noconfig*:
#
+ insert 'extern PyObject* PyInit_<module>(void);' before MARKER 1
#
+ insert '{"<module>", PyInit_<module>},' before MARKER 2
#
#
Copying Makefile.pre to Makefile:
#
- insert an identifying comment at the start
#
- replace _MODBUILT_NAMES_ by the list of *static* and *shared* modules
#
from Setup
#
- replace _MODDISABLED_NAMES_ by the list of *disabled* modules from Setup
#
- replace _MODOBJS_ by the list of objects from Setup (except for
#
Setup files after a -n option)
#
- replace _MODLIBS_ by the list of libraries from Setup
#
- for each object file mentioned in Setup, append a rule
#
'<file>.o: <file>.c; <build commands>' to the end of the Makefile
#
- for each module mentioned in Setup, append a rule
#
which creates a shared library version to the end of the Makefile
#
- for each variable definition found in Setup, insert the definition
#
before the comment 'Definitions added by makesetup'
#
Loop over command line options
