說明：

include $(DEPENDS)包含頭文件依賴文件不少事是會致使反應慢和兩次進入子目錄問題

 

 

一個直接編譯多個目錄下文件的makefile

CC=g++
MAKE=make
AR=ar cr
RM=rm -rf

#CFLAGS+=-Wall

LIBPATH=-L../comm/libs3/libuv-1.x/.libs\
        -L../comm/share/.lib\
        -L../comm/libs/asio/.lib\
        -L../comm/libs/db/.lib\
        -L/usr/lib64/mysql

CFLAGS= -I./\
        -I../comm/libs/utils\
        -I../comm/libs3/mysql/include\
        -I../comm/libs3\
        -I../comm/libs3/libuv-1.x/include
        
LDFLAGS= $(LIBPATH) -lm -ldl -lpthread -luv -lmysqlclient        

SRCSCPP=$(wildcard ../comm/libs/asio/*.cpp)\
        $(wildcard ../comm/libs/db/*.cpp)\
        $(wildcard ../comm/share/*.cpp)\
        $(wildcard sourcecmd/*.cpp)\
        $(wildcard sourcedb/*.cpp)\
        $(wildcard source/*.cpp)


OBJS=$(SRCSCPP:%.cpp=%.o) 

TARGET=test

all:$(TARGET) 


$(TARGET):$(OBJS)
    @$(CC) -o $(EXEPATH)/$@ $^ $(LDFLAGS)
    @echo create $@


%.o:%.cpp 
    @$(CC) -c $< -o $@ $(CFLAGS)
    @echo "Compile $<"


clean:
    @-$(RM) $(TARGET) $(OBJS) 

 

 頭文件依賴關係另外的寫法：

%.d:%.cpp
    $(GCC) -MM -MT "$*.o $*.d" $(INCS) $< >$@

 

文件排除

SRC := $(filter-out a.cpp b.cpp, $(SRC))

 

Make will set the special variable MAKECMDGOALS to the list of goals you specified on the command line. If no goals were given on the command line, this variable is empty. Note that this variable should be used only in special circumstances.
