最近因工作需要，要尝试徒手撸一份makefile文件，这份模版支持批量化，也不针对某一个C/CPP文件指定规则：

# Makefile for building: GuiDemo 
# by MT 2023-12-12 v1.0
# http://blog.csdn.net/wangningyu
CC            = gcc
CFLAGS        = -std=c11 -Wall
TARGET        = ./bin/GuiDemo

SRC_FLASH     = flash
SRC_GUI       = gui/Gui
SRC_MISC      = gui/Misc
SRC_USER      = gui/User
SRC_FONT      = gui/User/Fonts/

INC_ROOT      = .
INC_DIR       = gui/
INC_FLASH     = flash/
INC_GUI       = gui/Gui/
INC_MISC      = gui/Misc/
INC_USER      = gui/User/
INC_FONT      = gui/User/Fonts/
INC_SDL2      = SDL2/32/include/SDL2/
INCLUDE_DIR   = -I$(INC_ROOT) -I$(INC_DIR) -I$(INC_FLASH) -I$(INC_GUI) -I$(INC_MISC) -I$(INC_USER) -I$(INC_FONT) -I$(INC_SDL2)

LIB_DIR       = SDL2/32/lib/
LIBS          = -lSDL2 -lSDL2main

#获取所有的.c文件
SOURCES       = $(wildcard *.c $(SRC_FLASH)/*.c $(SRC_GUI)/*.c $(SRC_MISC)/*.c $(SRC_USER)/*.c $(SRC_FONT)/*.c)

#将.c文件替换成.o文件
OBJECTS       = $(SOURCES:.c=.o)

#链接规则
$(TARGET): $(OBJECTS)
	$(CC) $(CFLAGS) -o $@ $^ -L$(LIB_DIR) $(LIBS)

#编译规则
%.o: %.c
	$(CC) $(CFLAGS) -c -o $@ $< $(INCLUDE_DIR)

#.PHONY: clean

clean:
	@echo "Cleaning..."
	del /f /s /q .\*.o

支持MinGW，需要的直接拷贝走，免得以后再去写了~~
