我正在尝试在 QT-Creator 中使用 XML-RPC 客户端示例，并且出现了我似乎能够解决的链接错误。

主.cpp：

#include <cstdlib>
#include <string>
#include <iostream>
#include <xmlrpc-c/girerr.hpp>
#include <xmlrpc-c/base.hpp>
#include <xmlrpc-c/client_simple.hpp>

using namespace std;

int
main(int argc, char **) {

    if (argc-1 > 0) {
        cerr << "This program has no arguments" << endl;
        exit(1);
    }

    try {
        string const serverUrl("http://localhost:8080/RPC2");
        string const methodName("sample.add");

        xmlrpc_c::clientSimple myClient;
        xmlrpc_c::value result;

        myClient.call(serverUrl, methodName, "ii", &result, 5, 7);

        int const sum = xmlrpc_c::value_int(result);
            // Assume the method returned an integer; throws error if not

        cout << "Result of RPC (sum of 5 and 7): " << sum << endl;

   } catch (exception const& e) {
        cerr << "Client threw error: " << e.what() << endl;
    } catch (...) {
        cerr << "Client threw unexpected error." << endl;
    }

    return 0;
}

。轮廓：

这直接来自http://xmlrpc-c.sourceforge.net/doc/#clientexamplepp

我收到以下错误：

错误：未定义对“xmlrpc_c::clientSimple::clientSimple()”的引用

如您所见，我已包括

xmlrpc-c/client_simple.hpp

它提供了 clientSimple 的定义。我已经通过 ubuntu 软件中心“libxmlrpc-c++4-dev”和“xmlrpc-api-utils”安装了 xmlrpc 库

我错过了什么？任何帮助将不胜感激！
