makefile 内容如下

TARGET= main CPP_FILES = $(shell ls *.cpp) BASE = $(basename $(CPP_FILES)) OBJS = $(addsuffix .o, $(addprefix obj/,$(BASE)))    $(TARGET):$(OBJS)     -rm -f $@     g++ -o $(TARGET) $(OBJS)    obj/%.o:%.cpp     @if test -d"obj";then\         mkdir -p obj;\     fi;\     g++ -c -o $@ $<    clean:     -rm -f $(TARGET)     -rm -f obj/*.o

　同一目录下有三个文件 main.cpp Test1.cpp Test1.h Test2.cpp Test2.h

最后结果：

?

1 2 3

# make rm -f main g++ -o main obj/main.o obj/Test1.o obj/Test2.o

由于网页排版 makefile内容请大家注意重新使用TAB排版 否则可能编译不过

//=============================================================

CMAKE的测试环境如下

一个main.cpp 内容随意 可编译即可

一个CMakeLists.txt

内容如下:

?

1 2 3 4

PROJECT(main) CMAKE_MINIMUM_REQUIRED(VERSION 2.6) AUX_SOURCE_DIRECTORY(. DIR_SRCS) ADD_EXECUTABLE(main ${DIR_SRCS})

　　编译结果如下

?

1 2 3 4

cmake . -- Configuring done -- Generating done -- Build files have been written to: /home/A/Desktop/3

　　

?

1 2 3 4

make [100%] Building CXX object CMakeFiles/main.dir/main.cpp.o Linking CXX executable main [100%] Built target main

　　//===================================================

更进一步的 根目录下 放入main.cpp CMakeLists.txt

在新建一个子目录src 子目录下放置Test1.cpp Test1.h CMakeLists.txt

根目录CMakeLists.txt内容如下：

?

1 2 3 4 5 6

PROJECT(main) CMAKE_MINIMUM_REQUIRED(VERSION 2.6) ADD_SUBDIRECTORY( src ) AUX_SOURCE_DIRECTORY(. DIR_SRCS) ADD_EXECUTABLE(main ${DIR_SRCS}  ) TARGET_LINK_LIBRARIES( main Test )

　　子目录CMakeLists.txt内容如下：

?

1 2	AUX_SOURCE_DIRECTORY(. DIR_TEST1_SRCS) ADD_LIBRARY ( Test ${DIR_TEST1_SRCS})

　　编译显示如下:

?
