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:

选择静态库

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:

配置smb共享

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

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:

Makefile配置

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:

添加RCF源码

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>  VisualGDB: Trying to create D:\Code\C++\rcf.linux\rcf.linux\vgdb1889774204.tmp...

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:

rcftest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:

运行测试程序

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。
