crosstool-ng: Makefile.in@b64cfb67944e

     1 # Makefile.in for building crosstool-NG

     2 # This file serves as source for the ./configure operation

     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

    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.

    16 # CT_MAKEFLAGS will be used later, below...

    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

    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
