objects = hello.o name.o printing.o
exename = himake

$(exename): $(objects)
    $(CC) -o $(exename) $(objects)

%.o: %.cpp
    $(CC) -c  $^

我试图使用常见的后缀,所以我不需要先将3个文件编译成.o.这应该是使用%通配符完成所有三个.

我做的很长,但不是这样.

运行上面的makefile给出了以下错误:

[alex@pcc Dir]$ make
cc -o himake hello.o name.o printing.o
hello.o: In function `__static_initialization_and_destruction_0(int, int)':
hello.cpp:(.text+0x23): undefined reference to `std::ios_base::Init::Init()'
hello.o: In function `__tcf_0':
hello.cpp:(.text+0x66): undefined reference to `std::ios_base::Init::~Init()'

还有更多,我没有包括

文件:hello.cpp:

// hello.cpp

// standard library
#include <iostream>
#include <string>
using namespace std;

// user defined header files
#include "name.h"
#include "printing.h"

int main ()
{
    string name;

    name …
