使用VS+VisualGDB编译Linux版本RCF

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.dep1>  ar -r Debug/librcf.a Debug/RCF.o1>  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/Makefile1>  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。

debug.mak文件：
