Define targets from the command line after the macros from the command line and OOODMAKEMODE from the environment are set. 2007/09/14 03:40:58 vq 1.10.4.1: #i81296# Clear flags indicating that targets that infered makefiles (and their prerequisites) were previously build.

|
|
-- SYNOPSIS
|
|
-- The main program.
|
|
--
|
|
-- DESCRIPTION
|
|
--
|
|
-- dmake [-#dbug_string] [ options ]
|
|
-- [ macro definitions ] [ target ... ]
|
|
--
|
|
-- This file contains the main command line parser for the
|
|
-- make utility. The valid flags recognized are as follows:
|
|
--
|
|
-- -f file - use file as the makefile
|
|
-- -C file - duplicate console output to file (MSDOS only)
|
|
-- -K file - .KEEP_STATE file
|
|
-- -#dbug_string - dump out debugging info, see below
|
|
-- -v[cdfimrtw] - verbose, print what we are doing, as we do it
|
|
-- -m[trae] - measure timing information
|
|
--
|
|
-- options: (can be catenated, ie -irn == -i -r -n)
|
|
--
|
|
-- -A - enable AUGMAKE special target mapping
|
|
-- -B - enable non-use of TABS to start recipe lines
|
|
-- -c - use non-standard comment scanning
|
|
-- -d - do not use directory cache
|
|
-- -i - ignore errors
|
|
-- -n - trace and print, do not execute commands
|
|
-- -t - touch, update dates without executing commands
|
|
-- -T - do not apply transitive closure on inference rules
|
|
-- -r - don't use internal rules
|
|
-- -s - do your work silently
|
|
-- -S - force Sequential make, overrides -P
|
|
-- -q - check if target is up to date. Does not
|
|
-- do anything. Returns 0 if up to date, -1
|
|
-- otherwise.
|
|
-- -p - print out a version of the makefile
|
|
-- -P# - set value of MAXPROCESS
|
|
-- -E - define environment strings as macros
|
|
-- -e - as -E but done after parsing makefile
|
|
-- -u - force unconditional update of target
|
|
-- -k - make all independent targets even if errors
|
|
-- -V - print out this make version number
|
|
-- -M - Microsoft make compatibility, (* disabled *)
|
|
-- -h - print out usage info
|
|
-- -x - export macro defs to environment
|
|
-- -X - ignore #! lines found in makefile
|
|
--
|
|
-- NOTE: - #ddbug_string is only availabe for versions of dmake that
|
|
-- have been compiled with -DDBUG switch on. Not the case for
|
|
-- distributed versions. Any such versions must be linked
|
|
-- together with a version of Fred Fish's debug code.
|
|
--
|
|
-- NOTE: - in order to compile the code the include file stddef.h
|
|
-- must be shipped with the bundled code.
