本文介绍了一个Makefile配置示例，详细解释了如何设置编译环境、编译规则及清理过程。通过定义变量如CC、CPP和CFLAGS等，实现对C/C++源文件的编译和链接，同时提供了初始化目录结构、执行测试和安装目标程序的方法。

TARGET = main
OBJ_PATH = objs
PREFIX_BIN =

CC = gcc
CPP = g++
INCLUDES = -I include
LIBS =
CFLAGS =-Wall -Werror -O2 -g
LINKFLAGS =

SRCDIR = . ./lua

#C_SOURCES = $(wildcard *.c)
C_SRCDIR = $(SRCDIR)
C_SOURCES = $(foreach d,$(C_SRCDIR),$(wildcard $(d)/*.c) )
C_OBJS = $(patsubst %.c, $(OBJ_PATH)/%.o, $(C_SOURCES))

#CPP_SOURCES = $(wildcard *.cpp)
CPP_SRCDIR = $(SRCDIR)
CPP_SOURCES = $(foreach d,$(CPP_SRCDIR),$(wildcard $(d)/*.cpp) )
CPP_OBJS = $(patsubst %.cpp, $(OBJ_PATH)/%.o, $(CPP_SOURCES))

default:init compile

$(C_OBJS):$(OBJ_PATH)/%.o:%.c
	$(CC) -c $(CFLAGS) $(INCLUDES) $< -o $@

$(CPP_OBJS):$(OBJ_PATH)/%.o:%.cpp
	$(CPP) -c $(CFLAGS) $(INCLUDES) $< -o $@

init:
	$(foreach d,$(SRCDIR), mkdir -p $(OBJ_PATH)/$(d);)

test:
	@echo "C_SOURCES: $(C_SOURCES)"
	@echo "C_OBJS: $(C_OBJS)"
	@echo "CPP_SOURCES: $(CPP_SOURCES)"
	@echo "CPP_OBJS: $(CPP_OBJS)"

compile:$(C_OBJS) $(CPP_OBJS)
	$(CPP)  $^ -o $(TARGET)  $(LINKFLAGS) $(LIBS)

clean:
	rm -rf $(OBJ_PATH)
	rm -f $(TARGET)

install: $(TARGET)
	cp $(TARGET) $(PREFIX_BIN)

uninstall:
	rm -f $(PREFIX_BIN)/$(TARGET)

rebuild: clean init compile
