c++ RMI demo（使用RCF库）

作业要求

下载RCF库并编译成静态库/动态库
宿主机操作系统：ubuntu

wget https://www.deltavsoft.com/downloads/RCF-3.2.413.tar.gz # 下载RCF压缩包
tar xvf RCF-3.2.413.tar.gz # 解压到本地文件夹

在/root/code/rcf/RCF-3.2.413文件夹下

g++ -I include/  src/RCF/RCF.cpp -lpthread -ldl -luuid -c # 生成obj文件
# -l：链接第三方库 -I：头文件目录  -c只进行 预处理， 编译，汇编操作，生成.o (.obj)文件，不进行链接。

报错fatal error: uuid/uuid.h: No such file or directory
sudo apt-get install uuid-dev # 安装uuid-devuuid-dev
# 重新运行g++命令成功
mkdir lib # 创建lib文件夹，存放静态库与动态库文件

# 生成静态库
# 将所有.o文件打包为静态库，r将文件插入静态库中，c创建静态库，不管库是否存在，s写入一个目标文件索引到库中
ar rcs librcf.a  RCF.o 
mv librcf.a  lib/
mv RCF.o  lib/RCF_static.o


# 生成动态库
g++ -I include/  src/RCF/RCF.cpp -lpthread -ldl -luuid -c -fPIC 	# 参数-fPIC表示生成与位置无关代码
g++ -shared -o librcf.so RCF.o
mv librcf.so  lib/
mv RCF.o  lib/RCF_share.o

仿照/root/code/rcf/RCF-3.2.413/demo文件夹下的demo编写RMI程序
