Makefile for cpupower

Copyright (C) 2005,2006 Dominik Brodowski linux@dominikbrodowski.net

Based largely on the Makefile for udev by:

Copyright (C) 2003,2004 Greg Kroah-Hartman greg@kroah.com

OUTPUT=./ ifeq ("$(origin O)", "command line") OUTPUT := $(O)/ endif

ifneq ($(OUTPUT),)

check that the output directory actually exists

OUTDIR := $(shell cd $(OUTPUT) && pwd) $(if $(OUTDIR),, $(error output directory "$(OUTPUT)" does not exist)) endif

--- CONFIGURATION BEGIN ---

Set the following to `true' to make a unstripped, unoptimized

binary. Leave this set to `false' for production use.

DEBUG ?= true

make the build silent. Set this to something else to make it noisy again.

V ?= false

Internationalization support (output in different languages).

Requires gettext.

NLS ?= true

Set the following to 'true' to build/install the

cpufreq-bench benchmarking tool

CPUFREQ_BENCH ?= true

Do not build libraries, but build the code in statically

Libraries are still built, otherwise the Makefile code would

be rather ugly.

export STATIC ?= false

Prefix to the directories we're installing to

DESTDIR ?=

--- CONFIGURATION END ---

Package-related definitions. Distributions can modify the version

and should modify the PACKAGE_BUGREPORT definition

VERSION:= $(shell ./utils/version-gen.sh) LIB_MAJ= 0.0.1 LIB_MIN= 1

PACKAGE = cpupower PACKAGE_BUGREPORT = linux-pm@vger.kernel.org LANGUAGES = de fr it cs pt ka

Directory definitions. These are default and most probably

do not need to be changed. Please note that DESTDIR is

added in front of any of them

bindir ?= /usr/bin sbindir ?= /usr/sbin mandir ?= /usr/man includedir ?= /usr/include localedir ?= /usr/share/locale docdir ?= /usr/share/doc/packages/cpupower confdir ?= /etc/ bash_completion_dir ?= /usr/share/bash-completion/completions

Toolchain: what tools do we use, and what options do they need:

CP = cp -fpR INSTALL = /usr/bin/install -c INSTALL_PROGRAM = ${INSTALL} INSTALL_DATA = ${INSTALL} -m 644 #bash completion scripts get sourced and so they should be rw only. INSTALL_SCRIPT = ${INSTALL} -m 644

If you are running a cross compiler, you may want to set this

to something more interesting, like "arm-linux-". If you want

to compile vs uClibc, that can be done here as well.

CROSS = #/usr/i386-linux-uclibc/usr/bin/i386-uclibc- CC = $(CROSS)gcc LD = $(CROSS)gcc AR = $(CROSS)ar STRIP = $(CROSS)strip RANLIB = $(CROSS)ranlib HOSTCC = gcc MKDIR = mkdir

64bit library detection

include ../../scripts/Makefile.arch

ifeq ($(IS_64_BIT), 1) libdir ?= /usr/lib64 else libdir ?= /usr/lib endif

Now we set up the build system

GMO_FILES = ${shell for HLANG in ${LANGUAGES}; do echo $(OUTPUT)po/$$HLANG.gmo; done;}

export CROSS CC AR STRIP RANLIB CFLAGS LDFLAGS LIB_OBJS

check if compiler option is supported

cc-supports = ${shell if $(CC) ${1} -S -o /dev/null -x c /dev/null > /dev/null 2>&1; then echo "$(1)"; fi;}

use '-Os' optimization if available, else use -O2

OPTIMIZATION := $(call cc-supports,-Os,-O2)

WARNINGS := -Wall -Wchar-subscripts -Wpointer-arith -Wsign-compare WARNINGS += $(call cc-supports,-Wno-pointer-sign) WARNINGS += $(call cc-supports,-Wdeclaration-after-statement) WARNINGS += -Wshadow

Let all .o files depend on its .c file and all headers

Might be worth to put this into utils/Makefile at some point of time

we compile into subdirectories. if the target directory is not the

source directory, they might not exists. So we depend the various

files onto their directories.

DIRECTORY_DEPS = $(LIB_OBJS) $(UTIL_OBJS) $(GMO_FILES) $(DIRECTORY_DEPS): | $(sort $(dir $(DIRECTORY_DEPS)))

In the second step, we make a rule to actually create these directories

$(sort $(dir $(DIRECTORY_DEPS))): $(ECHO) " MKDIR " $@ $(QUIET) $(MKDIR) -p $@ 2>/dev/null
