#
# FILE DESCRIPTION
#
#      This is the makefile used in making the crosslinux build tool.
#
#      Conventions
#
#            Although the needed programs are known to exists, because
#            ./configure has successfully created this Makefile, use variables
#            such as $(install) for most all programs.  The reasons for this
#            are:
#            1) the path to the program may be unusual and ./configure has
#               found the path
#            2) to use the variables as they are set by ./configure, so when a
#               variable doesn't work then a needed program is found that is
#               not checked by ./configure.
#            The exceptions are the basic programs that a Linux system needs to
#            work, such as rm, rmdir, ls, cat, etc.  For any other programs
#            that could be not yet installed, or in an unusual path, use the
#            variables.
#

# Make MAKEFLAGS and Configuration                                            #
# *************************************************************************** #

# NOTICE (if this makefile need to re-invoke make on itself):
# GNU make 3.81 does not use MAKEFLAGS to set additional flags for the
# currently running make:  http://savannah.gnu.org/bugs/?20501
# The make manual says it should:
# http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion

# Do not print directories as descend into or ascended from.
#
ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)
   CL_MAKEFLAGS += --no-print-directory
endif

## This is useful if this makefile need to re-invoke make on itself.
## Do not to use the built rules and variables because at least one shell script
## will be generated from a .sh.in file and there is a built-in implicit rule
## '%.sh:' that has neither a pre-requisite nor a command associated, and that
## built-in implicit rule takes precedence over this makefile's non-built-in
## implicit rule '%: %.in' below.
##
## Use neither builtin rules, nor builtin variables.  The two tests are because
## if -R and -r are given on the command line, MAKEFLAGS contains 'Rr' instead
## of '-Rr'.  Adding '-Rr' to MAKEFLAGS adds it literally, not 'Rr'.
##
#ifeq ($(filter Rr,$(MAKEFLAGS)),)
#   ifeq ($(filter -Rr,$(MAKEFLAGS)),)
#      CL_MAKEFLAGS += -Rr
#   endif
#endif

MAKEFLAGS += $(CL_MAKEFLAGS)

# Remove suffix rules.  because at least one shell script will be generated
# from a .sh.in file and there is a built-in implicit rule '%.sh:' that has
# neither a pre-requisite nor a command associated, and that built-in implicit
# rule takes precedence over this makefile's non-built-in implicit rule
# '%: %.in' below.
