# procps Makefile# Albert Cahalan, 2002-2004## Recursive make is considered harmful:# http://google.com/search?q=%22recursive+make+considered+harmful%22## For now this Makefile uses explicit dependencies. The project# hasn't grown big enough to need something complicated, and the# dependency tracking files are an ugly annoyance.## This file includes */module.mk files which add on to variables:# FOO += bar/baz### Set (or uncomment) SKIP if you wish to avoid something.# For example, you may prefer the /bin/kill from util-linux or bsdutils.VERSION      := 3SUBVERSION   := 2MINORVERSION := 7TARVERSION   := $(VERSION).$(SUBVERSION).$(MINORVERSION)############ vars# so you can disable them or choose alternatesldconfig := ldconfigln_f     := ln -fln_sf    := ln -sfinstall  := install -D --owner 0 --group 0# Lame x86-64 /lib64 and /usr/lib64 abomination:lib64    := lib$(shell [ -d /lib64 ] && echo 64)usr/bin                  := $(DESTDIR)/usr/bin/bin                      := $(DESTDIR)/bin/sbin                     := $(DESTDIR)/sbin/usr/proc/bin             := $(DESTDIR)/usr/bin/man1                     := $(DESTDIR)/usr/share/man/man1/man5                     := $(DESTDIR)/usr/share/man/man5/man8                     := $(DESTDIR)/usr/share/man/man8/lib                      := $(DESTDIR)/$(lib64)/usr/lib                  := $(DESTDIR)/usr/$(lib64)/usr/include              := $(DESTDIR)/usr/include/#SKIP     := $(bin)kill $(man1)kill.1#BINFILES := $(usr/bin)uptime $(usr/bin)tload $(usr/bin)free $(usr/bin)w \            $(usr/bin)top $(usr/bin)vmstat $(usr/bin)watch $(usr/bin)skill \            $(usr/bin)snice $(bin)kill $(sbin)sysctl $(usr/bin)pmap \            $(usr/proc/bin)pgrep $(usr/proc/bin)pkill $(usr/bin)slabtop \            $(usr/proc/bin)pwdx#MANFILES := $(man1)uptime.1 $(man1)tload.1 $(man1)free.1 $(man1)w.1 \            $(man1)top.1 $(man1)watch.1 $(man1)skill.1 $(man1)kill.1 \            $(man1)snice.1 $(man1)pgrep.1 $(man1)pkill.1 $(man1)pmap.1 \            $(man5)sysctl.conf.5 $(man8)vmstat.8 $(man8)sysctl.8 \            $(man1)slabtop.1 $(man1)pwdx.1#TARFILES := AUTHORS BUGS NEWS README TODO COPYING COPYING.LIB \            Makefile procps.lsm procps.spec v t README.top CodingStyle \            sysctl.conf minimal.c $(notdir $(MANFILES)) dummy.c \            uptime.c tload.c free.c w.c top.c vmstat.c watch.c skill.c \            sysctl.c pgrep.c top.h pmap.c slabtop.c pwdx.c# Stuff (tests, temporary hacks, etc.) left out of the standard tarball# plus the top-level Makefile to make it work stand-alone._TARFILES := MakefileCURSES := -lncurses# This seems about right for the dynamic library stuff.# Something like this is probably needed to make the SE Linux# library loading not conflict with embedded systems stuff.##ifeq ($(SHARED),1)#ldl := -ldl#LIBTYPE := -DSHAREDLIB#else#LIBTYPE := -DSTATICLIB#endif# Preprocessor flags.CC := arm-linux-gccPKG_CPPFLAGS := -D_GNU_SOURCE -I procCPPFLAGS     := -I/usr/include/ncursesALL_CPPFLAGS := $(PKG_CPPFLAGS) $(CPPFLAGS)# Left out -Wconversion due to noise in glibc headers.# Left out -Wunreachable-code and -Wdisabled-optimization# because gcc spews many useless warnings with them.## Since none of the PKG_CFLAGS things are truly required# to compile procps, they might best be moved to CFLAGS.# On the other hand, they aren't normal -O -g things either.## Note that -O2 includes -fomit-frame-pointer only if the arch# doesn't lose some debugging ability.#PKG_CFLAGS   := -fno-common -ffast-math \  -W -Wall -Wshadow -Wcast-align -Wredundant-decls \  -Wbad-function-cast -Wcast-qual -Wwrite-strings -Waggregate-return \  -Wstrict-prototypes -Wmissing-prototypes# Note that some stuff below is conditional on CFLAGS containing# an option that starts with "-g".
