# 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 |
