# Makefile.in for building crosstool-NG

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

# This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS

# to set additional flags in the current Makfile ( see:

# http://savannah.gnu.org/bugs/?20501 ), although the make manual says it

# should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )

# so we have to work it around by calling ourselves back if needed

# So why do we need not to use the built rules and variables? Because we

# need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in

# 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 our non-built-in implicit rule '%: %.in', below.

# CT_MAKEFLAGS will be used later, below...

# Do not print directories as we descend into them

ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)

CT_MAKEFLAGS += --no-print-directory

endif

# Use neither builtin rules, nor builtin variables

# Note: dual test, because if -R and -r are given on the command line

# (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding

# '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )

ifeq ($(filter Rr,$(MAKEFLAGS)),)

ifeq ($(filter -Rr,$(MAKEFLAGS)),)

CT_MAKEFLAGS += -Rr

endif # No -Rr

endif # No Rr

# Remove any suffix rules
