Makefile's several ways of writing "original"

Makefile Writing

Make-f makefile1 Designation

The following is my point Makefile study notes, and then share a good write makefile summary of the website:

Method IX,

The directory structure is as follows

Executable file under Bin

Include as header file

Intermediate file under obj for compilation

Various C files under the package

root directory under Makefile

-include rules.mk

Test_res: = Bin/regdebug

OBJECTS = $ (objdir)/MAIN.O

-include./package/obj.mk

$ (objdir)/%.o:%.c

$ (CC) $ (includdir)-C $<-o [email protected]-std=gnu99

$ (objdir)/%.o:./package/%.c

$ (CC) $ (includdir)-C $<-o [email protected]-std=gnu99

$ (Test_res): $ (OBJECTS)

$ (CC) $^-o [email protected]-lpthread-std=gnu99

chmod a+x [email protected]

. Phony:clean

Clean

Rm-rf. *.cmd *.o *.mod.c. Tmp_versions module.symvers. MAKEFILE.SWP $ (test_res)

RM-RF $ (OBJECTS)

root directory under RULES.MK:

cc=arm-none-linux-gnueabi-gcc

Includdir=-i include

Objdir=obj

Package directory under OBJ.MK

OBJECTS + =/obj/uart.o \

./OBJ/CONSOLE.O \

./OBJ/REG_DATA.O \

./OBJ/FUNC.O \

./OBJ/RUN.O \

./obj/revdataone.o
