It will shave a few bytes off them. + + +* Customization + ------------- + + You can customize paths via flags given to configure. + See ./configure --help for a list of all available configure options. + + +* Environment variables + --------------------- + + Controlling a build process via environment variables is a big and +dangerous hammer. You should try and pass flags to configure instead; +nevertheless, the standard environment variables are recognized. + + The value of the CROSS_COMPILE environment variable will prefix the +building tools' names. The --enable-cross option is preferred, see +"Cross-compilation" below. + + If the CC environment variable is set, its value will override compiler +detection by configure. + + The values of CFLAGS, CPPFLAGS and LDFLAGS will be appended to flags +auto-detected by configure. To entirely override the flags set by +configure, use make -e. + + The value of LDLIBS will be appended by make to command lines that link +an executable, even without the -e option. + + The Makefile supports the DESTDIR convention for staging. + + +* Static binaries + --------------- + + By default, binaries are linked against static versions of all the +libraries they depend on, except for the libc. You can enforce +linking against the static libc with --enable-static-libc. + + (If you are using a GNU/Linux system, be aware that the GNU libc +behaves badly with static linking and produces huge executables, +which is why it is not the default. Other libcs are better suited +to static linking, for instance musl: http://musl-libc.org/) + + +* Cross-compilation + ----------------- + + skarnet.org packages centralize all the difficulty of +cross-compilation in one place: skalibs. Once you have +cross-compiled skalibs, the rest is easy. + + Use the --enable-cross=PREFIX option to configure, or simply +--enable-cross if your default toolchain is a cross-compiling +toolchain. And make sure to use the correct version of skalibs +for your target, and the correct sysdeps directory, making use +of the --with-include, --with-lib, --with-dynlib and --with-sysdeps +options as necessary. + + +* The slashpackage convention + --------------------------- + + The slashpackage convention (http://cr.yp.to/slashpackage.html) +is a package installation scheme that provides a few guarantees +over other conventions such as the FHS, for instance fixed +absolute pathnames. skarnet.org packages support it: use the +--enable-slashpackage option to configure, or +--enable-slashpackage=DIR for a prefixed DIR/package tree. +This option will activate slashpackage support during the build +and set slashpackage-compatible installation directories. +Other options setting individual installation directories will be +ignored. + + When using slashpackage, two additional Makefile targets are +available after "make install": + - "make update" changes the default version of the software to the +freshly installed one. (This is useful when you have several installed +versions of the same software, which slashpackage supports.) + - "make -L global-links" adds links from /command and /library.so to the +default version of the binaries and shared libraries. The "-L" option to +make is necessary because targets are symbolic links, and the default make +behaviour is to check the pointed file's timestamp and not the symlink's +timestamp. + + +* Out-of-tree builds + ------------------ + + skarnet.org packages do not support out-of-tree builds. They +are small, so it does not cost much to duplicate the entire +source tree if parallel builds are needed. diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..7d8901c --- /dev/null +++ b/Makefile @@ -0,0 +1,121 @@ +# +# This Makefile requires GNU make. +# +# Do not make changes here. +# Use the included .mak files. +# + +it: all + +CC = $(error Please use ./configure first) + +include package/targets.mak +include package/deps.mak +-include config.mak + +version_m := $(basename $(version)) +version_M := $(basename $(version_m)) +version_l := $(basename $(version_M)) +CPPFLAGS_ALL := -iquote src/include-local -Isrc/include $(CPPFLAGS) +CFLAGS_ALL := $(CFLAGS) -pipe -Wall +CFLAGS_SHARED := -fPIC +LDFLAGS_ALL := $(LDFLAGS) +LDFLAGS_SHARED := -shared +LDLIBS_ALL := $(LDLIBS) +REALCC = $(CROSS_COMPILE)$(CC) +AR := $(CROSS_COMPILE)ar +RANLIB := $(CROSS_COMPILE)ranlib +STRIP := $(CROSS_COMPILE)strip +INSTALL := ./tools/install.sh + +ALL_BINS := $(LIBEXEC_TARGETS) $(BIN_TARGETS) $(SBIN_TARGETS) +ALL_LIBS := $(SHARED_LIBS) $(STATIC_LIBS) +ALL_INCLUDES := $(wildcard src/include/$(package)/*.h) + +all: $(ALL_LIBS) $(ALL_BINS) $(ALL_INCLUDES) + +clean: + @exec rm -f $(ALL_LIBS) $(ALL_BINS) $(wildcard src/*/*.o src/*/*.lo) + +distclean: clean + @exec rm -f config.mak src/include/${package}/config.h + +tgz: distclean + @. package/info && \ + rm -rf /tmp/$$package-$$version && \ + cp -a . /tmp/$$package-$$version && \ + cd /tmp && \ + tar -zpcv --owner=0 --group=0 --numeric-owner --exclude=.git* -f /tmp/$$package-$$version.tar.gz $$package-$$version && \ + exec rm -rf /tmp/$$package-$$version + +strip: $(ALL_LIBS) $(ALL_BINS) +ifneq ($(strip $(ALL_LIBS)),) + exec ${STRIP} -x -R .note -R .comment -R .note.GNU-stack $(ALL_LIBS) +endif +ifneq ($(strip $(ALL_BINS)),) + exec ${STRIP} -R .note -R .comment -R .note.GNU-stack $(ALL_BINS) +endif + +install: install-dynlib install-libexec install-bin install-sbin install-lib install-include +install-dynlib: $(SHARED_LIBS:lib%.so=$(DESTDIR)$(dynlibdir)/lib%.so) +install-libexec: $(LIBEXEC_TARGETS:%=$(DESTDIR)$(libexecdir)/%) +install-bin: $(BIN_TARGETS:%=$(DESTDIR)$(bindir)/%) +install-sbin: $(SBIN_TARGETS:%=$(DESTDIR)$(sbindir)/%) +install-lib: $(STATIC_LIBS:lib%.a=$(DESTDIR)$(libdir)/lib%.a) +install-include: $(ALL_INCLUDES:src/include/$(package)/%.h=$(DESTDIR)$(includedir)/$(package)/%.h) + +ifneq ($(exthome),) + +update: + exec $(INSTALL) -l $(notdir $(home)) $(DESTDIR)$(exthome) + +global-links: $(DESTDIR)$(exthome) $(SHARED_LIBS:lib%.so=$(DESTDIR)$(sproot)/library.so/lib%.so) $(BIN_TARGETS:%=$(DESTDIR)$(sproot)/command/%) $(SBIN_TARGETS:%=$(DESTDIR)$(sproot)/command/%) + +$(DESTDIR)$(sproot)/command/%: $(DESTDIR)$(home)/command/% + exec $(INSTALL) -D -l ..$(exthome)/command/$(<F) $@ + +$(DESTDIR)$(sproot)/library.so/lib%.so: $(DESTDIR)$(dynlibdir)/lib%.so + exec $(INSTALL) -D -l ..$(exthome)/library.so/$(<F) $@ + +.PHONY: update global-links + +endif + +$(DESTDIR)$(dynlibdir)/lib%.so: lib%.so + $(INSTALL) -D -m 755 $< $@.$(version) && \ + $(INSTALL) -l $<.$(version) $@.$(version_m) && \ + $(INSTALL) -l $<.$(version_m) $@.$(version_M) && \ + $(INSTALL) -l $<.$(version_M) $@.$(version_l) && \ + exec $(INSTALL) -l $<.$(version_l) $@ + +$(DESTDIR)$(libexecdir)/% $(DESTDIR)$(bindir)/% $(DESTDIR)$(sbindir)/%: % package/modes + exec $(INSTALL) -D -m 600 $< $@ + grep -- ^$(@F) < package/modes | { read name mode owner && \ + if [ x$$owner != x ] ; then chown -- $$owner $@ ; fi && \ + chmod $$mode $@ ; } + +$(DESTDIR)$(libdir)/lib%.a: lib%.a + $(INSTALL) -D -m 644 $< $@ + +$(DESTDIR)$(includedir)/$(package)/%.h: src/include/$(package)/%.h + exec $(INSTALL) -D -m 644 $< $@ + +%.o: %.c + exec $(REALCC) $(CPPFLAGS_ALL) $(CFLAGS_ALL) -c -o $@ $< + +%.lo: %.c + exec $(REALCC) $(CPPFLAGS_ALL) $(CFLAGS_ALL) $(CFLAGS_SHARED) -c -o $@ $< + +$(ALL_BINS): + exec $(REALCC) -o $@ $(CFLAGS_ALL) $(LDFLAGS_ALL) $(LDFLAGS_NOSHARED) $^ $(LDLIBS_ALL) + +lib%.a: + exec $(AR) rc $@ $^ + exec $(RANLIB) $@ + +lib%.so: + exec $(REALCC) -o $@ $(CFLAGS_ALL) $(CFLAGS_SHARED) $(LDFLAGS_ALL) $(LDFLAGS_SHARED) -Wl,-soname,$@.$(version_l) $^ + +.PHONY: it all clean distclean tgz strip install install-dynlib install-bin install-sbin install-lib install-include + +.DELETE_ON_ERROR: @@ -0,0 +1,25 @@ +s6-portable-utils - tiny general Unix utilities +----------------------------------------------- + +s6-portable-utils is a set of tiny general Unix utilities, +often performing well-known tasks such as cut and grep + but optimized for simplicity and small size.
