RPC通信框架——RCF介绍中说了,RCF本身是支持跨平台的,其代码放到Linux平台,是可以通过gcc、make等工具,编译通过的。
官方提供的源码中,只有cmake编译脚本,并没有提供Makefile,如果想直接使用make编译,就必须自己写Makefile。
抛开这些不说,本文主要介绍在Windows系统上,通过VS与VisualGDB来完成Linux版本的RCF库的编译和调试。
使用VS+VisualGDB编译调试Linux程序 ,文中已经简单介绍了VisualGDB的用法,本文直奔主题,介绍RCF静态库的编译方式。
通过向导配置项目
通过向导创建项目时,比较重要的几个步骤如下,
选择项目类型为静态库:
通过Windows共享文件夹以及smb服务的方式在Windows与Linux之前共享代码:
具体命令为:
mount.cifs //192.168.3.125/rcf.linux '/code/rcf' -o user=hbccdf,pass='****',noperm
配置目录结构
配置后的目录结构如下
D:\CODE\C++\RCF.LINUX
├─Debug
├─include
│ ├─RCF
│ │ ├─external
│ │ │ └─asio
│ │ │ └─asio
│ │ │ ├─detail
│ │ │ │ └─impl
│ │ │ ├─impl
│ │ │ ├─ip
│ │ │ │ ├─detail
│ │ │ │ │ └─impl

│ │ │ │ └─detail
│ │ │ │ └─impl
│ │ │ ├─posix
│ │ │ ├─ssl
│ │ │ │ └─detail
│ │ │ └─windows
│ │ ├─test
│ │ ├─thread
│ │ │ └─impl
│ │ ├─utf8
│ │ │ └─detail
│ │ └─util
│ │ └─Platform
│ │ └─OS

│ │ └─Windows
│ └─SF
├─rcf.linux
│ ├─Debug
│ │ └─rcf.linux.tlog
│ ├─obj
│ │ └─Win32
│ │ └─Debug
│ └─VisualGDBCache
│ └─rcf.linux-Debug
└─src
├─RCF
│ ├─test
│ └─util
└─SF
修改项目配置
通过VisualGDB修改项目配置,也就是Makefile相关配置,也可以通过VS直接改文本内容:
添加RCF源代码
由于RCF的源码全被包含在RCF.cpp文件中,所以,只需要在VS中添加RCF.cpp文件即可:
完成配置并进行编译
至此,就完成了所有的配置,可以通过VS进行编译了,如下是编译信息:
1>------ 已启动生成: 项目: rcf.linux, 配置: Debug Win32 ------
1> VisualGDB: Testing shared folder-based mapping D:\Code\C++\rcf.linux\rcf.linux <=> 192.168.3.128:/code/rcf/rcf.linux...

1> ar -r Debug/librcf.a Debug/RCF.o
1> ar: creating Debug/librcf.a
========== 生成: 成功 1 个,失败 0 个,最新 0 个,跳过 0 个 ==========
添加测试程序
通过VisualGDB向导添加测试程序rcftest,
然后进行项目配置:
添加测试代码——通过TCP进行通信
RCF进程间通信Demo程序,文中说了通过RCF进行进程间通信的具体步骤,
首先添加接口 I_HELLO:
#pragma once #include "rcf/rcf.hpp"
#include <iostream>
#include <string>
using namespace std; RCF_BEGIN(I_HELLO, "I_HELLO")
RCF_METHOD_V1(void, SayHello, const string&)
RCF_METHOD_R1(int, add, int&)
RCF_METHOD_V0(void, test)
RCF_END(I_HELLO) class HelloImpl
{
public:
void SayHello(const string& world)
{
cout << "hello " << world << endl;
}
int add(int& a)
{
a = a + a;
return a + 2;
}
void test()
{}
};
然后添加测试代码:
#include <iostream>
#include "hello.h"
using namespace std; int main(int argc, char *argv[])
{
RCF::RcfInitDeinit rcf_init;
HelloImpl hello;
RCF::RcfServer server(RCF::TcpEndpoint(50001));
server.bind<I_HELLO>(hello);
server.start(); RcfClient<I_HELLO> client(RCF::TcpEndpoint(50001));
string str = "test";
client.SayHello(str);
int a = 3;
int b = client.add(a);
cout << "a = " << a << ", b = " << b << endl; for (int i = 0; i < 20000; ++i)
{
client.test();
}
cout << "完成" << endl;
}
如下是编译信息:
1>------ 已启动生成: 项目: rcftest, 配置: Debug Win32 ------
1> VisualGDB: Testing shared folder-based mapping D:\Code\C++\rcf.linux\rcftest <=> 192.168.3.128:/code/rcf/rcftest...
1> VisualGDB: Trying to create D:\Code\C++\rcf.linux\rcftest\vgdb1568095730.tmp...
1> Updating D:\Code\C++\rcf.linux\rcftest\Makefile
1> VisualGDB: Updated source file list in D:\Code\C++\rcf.linux\rcftest\Makefile. Enable verbose mode for more details.
1> VisualGDB: Run "make CONFIG=Debug" in directory "/code/rcf/rcftest" on root@192.168.3.128 (SSH)
1> g++ -ggdb -ffunction-sections -O0 -I../include -DDEBUG -c rcftest.cpp -o Debug/rcftest.o -MD -MF Debug/rcftest.dep
1> g++ -o Debug/rcftest -Wl,-gc-sections -L../rcf.linux/Debug -Wl,--start-group Debug/rcftest.o -lrcf -lpthread -ldl -Wl,--rpath='$ORIGIN' -Wl,--end-group
========== 生成: 成功 1 个,失败 0 个,最新 0 个,跳过 0 个 ==========
运行测试程序并查看测试结果
可以通过VS F5调试运行,查看运行结果:
这样,通过VS+VisualGDB编译RCF的工作就完成了。
VisualGDB生成的所有Makefile代码
虽然是在Windows系统上,使用VS进行编译开发,实际上还是需要生成Makefile文件,然后通过make进行编译。
每个项目会生成几个与项目配置有关的makefile文件,比如debug.mak文件,以及一个与配置无关的文件Makefile,编译的时候会根据配置选择对应的debug.mak或者release.mak。
