     1 # Makefile.in for building crosstool-NG
     2 # This file serves as source for the ./configure operation
     3 
     4 # This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
     5 # to set additional flags in the current Makfile ( see:
     6 # http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
     7 # should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
     8 # so we have to work it around by calling ourselves back if needed
     9 
    10 # So why do we need not to use the built rules and variables? Because we
    11 # need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
    12 # and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
    13 # nor a command associated, and that built-in implicit rule takes precedence
    14 # over our non-built-in implicit rule '%: %.in', below.
    15 
    16 # CT_MAKEFLAGS will be used later, below...
    17 
    18 # Do not print directories as we descend into them
    19 ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)
    20 CT_MAKEFLAGS += --no-print-directory
    21 endif
    22 
    23 # Use neither builtin rules, nor builtin variables
    24 # Note: dual test, because if -R and -r are given on the command line
    25 # (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding
    26 # '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )
    27 ifeq ($(filter Rr,$(MAKEFLAGS)),)
    28 ifeq ($(filter -Rr,$(MAKEFLAGS)),)
    29 CT_MAKEFLAGS += -Rr
    30 endif # No -Rr
    31 endif # No Rr
