# tool/update-deps verify makefile dependencies.
|
|
|
|
# Requirements:
|
|
# gcc 4.5 (for -save-temps=obj option)
|
|
# GNU make (for -p option)
|
|
#
|
|
# Warning: ccache (and similar tools) must be disabled for
|
|
# -save-temps=obj to work properly.
|
|
#
|
|
# Usage:
|
|
# 1. Compile ruby with -save-temps=obj option.
|
|
# Ex. ./configure debugflags='-save-temps=obj -g' && make all golf
|
|
# 2. Run tool/update-deps to show dependency problems.
|
|
# Ex. ruby tool/update-deps
|
|
# 3. Use --fix to fix makefiles.
|
|
# Ex. ruby tool/update-deps --fix
|
|
#
|
|
# Other usages:
|
|
# * Fix makefiles using previously detected dependency problems
|
|
# Ex. ruby tool/update-deps --actual-fix [file]
|
|
# "ruby tool/update-deps --fix" is same as "ruby tool/update-deps | ruby tool/update-deps --actual-fix".
