Sure. At least simple ones are under tools/gpio, tools/iio, etc. You may compare them to see what's different and what's common and base Makefile here on that. I dunno if there is any tool under tools/power to use that, it might give an example of `descend` feature in Makefile. > > > @@ -0,0 +1,31 @@ > > > +# SPDX-License-Identifier: GPL-2.0 > > > +CC = $(CROSS_COMPILE)gcc > > > +BUILD_OUTPUT := $(CURDIR) > > > +PREFIX ?= /usr > > > +DESTDIR ?= > > > + > > > +override CFLAGS += -D__EXPORTED_HEADERS__ -Wall -D_GNU_SOURCE > > > +override CFLAGS += -I$(CURDIR)/../../../../include/uapi/ > > > +override CFLAGS += -I$(CURDIR)/../../../../include/ > > > + > > > +%: %.c > > > + @mkdir -p $(BUILD_OUTPUT) > > > + $(CC) $(CFLAGS) $< -o $(BUILD_OUTPUT)/$@ $(LDFLAGS) > > > + > > > +DEPS = isst.h > > > +OBJ = isst_config.o isst_core.o isst_display.o > > > + > > > +%.o: %.c $(DEPS) > > > + $(CC) -c -o $(BUILD_OUTPUT)/$@ $< $(CFLAGS) > > > + > > > +intel-speed-select: $(OBJ) > > > + $(CC) -o $(BUILD_OUTPUT)/$@ $^ $(CFLAGS) > > > + > > > +.PHONY : clean > > > +clean : > > > + @rm -f $(BUILD_OUTPUT)/intel-speed-select > > > + @rm -f $(BUILD_OUTPUT)/*.o > > > + > > > +install : intel-speed-select > > > + install -d $(DESTDIR)$(PREFIX)/sbin > > > + install $(BUILD_OUTPUT)/intel-speed-select > > > $(DESTDIR)$(PREFIX)/sbin/intel-speed-select -- With Best Regards, Andy Shevchenko
