# `sink` - sinks all input to /dev/null # Usage: `sink [ []]` # # Targets: # `sink` (default): stripped `release` target. output: `sink` # `release`: optimised build. output: `sink-release` # `debug`: unoptimised build with debuginfo. output: `sink-debug` # `clean`: remove all previous object and binary output files # # Environment variables: # * `SHARED` - set to "yes" to prevent passing `--static` to cc # * `TARGET_ARCH` - target arch (`-march=`), or set `TARGET_ARCH=` to force set to generic target. (default [release only]: `native`) # * `CFLAGS`, `COMMON_FLAGS` - passthrough to cc # * `LDFLAGS` - passthrough to ld # * `DEBUG_CFLAGS`, `DEBUG_LDFLAGS` - passthrough to cc / ld on target `debug` # * `RELEASE_CFLAGS`, `RELEASE_LDFLAGS` - passthrough to cc / ld on target `release` # # Make overridable only: # * `STRIP` - Strip command for default output (stripped release) target (`make sink`). set `make STRIP=:` to prevent stripping entirely. (NOTE: When using `make install`, `STRIP=:` will not work, instead, paradoxically, set `STRIP=true`, they have the same effect for all targets) PROJECT=sink DESCRIPTION=sink all input and output of a program to /dev/null VERSION=0.2.0 AUTHOR=Avril LICENSE=GPL3+ SRC=$(wildcard *.c) OUTPUT=$(PROJECT) ifeq ($(PREFIX),) PREFIX := /usr/local endif FEATURES?= ifneq ($(FEATURES),) FEATURES:=$(addprefix -DFEATURE_,$(FEATURES)) endif COMMON_FLAGS+= -W -Wall -Wextra -Wstrict-aliasing -fno-strict-aliasing "-D_AUTHOR=\"$(AUTHOR)\"" "-D_LICENSE=\"$(LICENSE)\"" "-D_VERSION=\"$(VERSION)\"" "-D_PROJECT=\"$(PROJECT)\"" "-D_DESCRIPTION=\"$(DESCRIPTION)\"" $(FEATURES) TARGET_ARCH?=native ifneq ($(TARGET_ARCH),) TARGET_ARCH:=$(addprefix -march=,$(TARGET_ARCH)) endif RELEASE_CFLAGS+= $(TARGET_ARCH) -fgraphite \ -floop-interchange -ftree-loop-distribution -floop-strip-mine -floop-block \ -fno-stack-check RELEASE_CFLAGS+= -O3 -flto -DRELEASE RELEASE_LDFLAGS+= -Wl,-O3 -Wl,-flto DEBUG_CFLAGS+=-Og -g3 -ggdb -gz -DDEBUG DEBUG_LDFLASG+=-Wl,-g CFLAGS += $(COMMON_FLAGS) --std=gnu17 LDFLAGS += ifneq ($(SHARED),yes) CFLAGS+=--static endif OBJ = $(SRC:.c=.o) STRIP=strip # Phonies .PHONY: $(OUTPUT) $(OUTPUT): $(PROJECT)-release mv $< $@ $(STRIP) $@ .PHONY: release release: $(PROJECT)-release .PHONY: debug debug: $(PROJECT)-debug # Targets %.o: %.c $(CC) -c $< $(CFLAGS) -o $@ $(LDFLAGS) $(PROJECT)-debug: CFLAGS+=$(DEBUG_CFLAGS) $(PROJECT)-debug: LDFLAGS+=$(DEBUG_LDFLAGS) $(PROJECT)-debug: $(OBJ) $(CC) $^ -fwhole-program $(CFLAGS) -o $@ $(LDFLAGS) $(PROJECT)-release: CFLAGS+=$(RELEASE_CFLAGS) $(PROJECT)-release: LDFLAGS+=$(RELEASE_LDFLAGS) $(PROJECT)-release: $(OBJ) $(CC) $^ -fwhole-program $(CFLAGS) -o $@ $(LDFLAGS) clean: rm -f *.o rm -f $(OUTPUT) $(PROJECT)-* .PHONY: install install: install -s --strip-program=$(STRIP) -m 755 $(OUTPUT) $(DESTDIR)$(PREFIX)/bin .PHONY: uninstall uninstall: rm -f $(DESTDIR)$(PREFIX)/bin/$(OUTPUT)
