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 │ │ │ │ └─impl │ │ │ ├─local │ │ │ │ └─detail │ │ │ │ └─impl │ │ │ ├─posix │ │ │ ├─ssl │ │ │ │ └─detail │ │ │ └─windows │ │ ├─test │ │ ├─thread │ │ │ └─impl │ │ ├─utf8 │ │ │ └─detail │ │ └─util │ │ └─Platform │ │ └─OS │ │ ├─Unix │ │ └─Windows │ └─SF ├─rcf.linux │ ├─Debug │ │ └─rcf.linux.tlog │ ├─obj │ │ └─Win32 │ │ └─Debug │ └─VisualGDBCache │ └─rcf.linux-Debug └─src ├─RCF │ ├─test │ └─util └─SF
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:
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:
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> VisualGDB: Run "make CONFIG=Debug" in directory "/code/rcf/rcf.linux" on root@192.168.3.128 (SSH) 1> g++ -ggdb -ffunction-sections -O0 -I../include -DDEBUG -c ../src/RCF/RCF.cpp -o Debug/RCF.o -MD -MF Debug/RCF.dep 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 ==========
通过VisualGDB向导添加测试程序rcftest,
然后进行项目配置:
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.

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。
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。

Makefile文件:
与rcf.linux项目的Makefile文件基本上是一样的,就不在这里列举了。
