补充说明
1.
c++11编辑器需要加-std=c++11
g++ -o TestAll.o -c TestAll.cpp -I./include -std=c++11
2.
apt-get install make
apt-get install g++
apt-get install build-essential
root@x::x#uname -r
4.4.0-62-generic
root@x:x# apt-get install linux-headers-'4.4.0-62-generic'
ls /usr/bin/gcc*
apt-get install gcc-5
apt-get install g++-5

5.用得文件
example# ls
functions.cpp functions.h functions.o functionsTest.cpp functionsTest.o include lib main TestAll.cpp TestAll.o
【functions.cpp】
//functions.cpp
#include<iostream>
#include "functions.h"
using namespace std;
int add(int one,int two){ return one+two; }
int myMinus(int one,int two){ return one-two; }
int multiply(int one,int two){ return one*two; }
int divide(int one,int two){ return one/two; }
