On OS X, Apple supply an old gperf (3.0.3) with xcode and
xcode commandline tools which causes build failures:
./zconf.hash.c:183:17: error: expected expression
{offsetof(struct kconf_id_strings_t, kconf_id_strings_str2),
.. upgrading to gperf 3.0.4 was sufficient to fix this,
so this option allows the user to specify the gperf
program that they wish to use.
To install gperf 3.0.4 from homebrew, I did:
brew tap homebrew/dupes
brew install homebrew/dupes/gperf
.. then passed --with-gperf=$BREWFIX/Cellar/gperf/3.0.4/bin/gperf
to configure

# 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' )
|
|
# Further: quad test because the flags 'rR' and '-rR' can be reordered.
