| # 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.dist 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 void init<module>(void);' before MARKER 1 |
| # + insert '{"<module>", initmodule},' before MARKER 2 |
| # |
| # Copying Makefile.pre to Makefile: |
| # - insert an identifying comment at the start |
| # - 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 |
