为了熟悉使用 WSF/C++ 框架的 RESTful Web 服务定义（服务器和客户端），我决定遵循快速入门指南（参见http://wso2.org/project/wsf/cpp/2.0。 0/docs/ )。我已经成功地从源代码和 hello 服务器编译并安装了框架。问题是当我尝试编译 hello 客户端时。

请在下面找到 c++ 代码 (hello_cli.cpp) 和编译输出。

#include <stdio.h>
#include <ServiceClient.h>
#include <OMElement.h>
#include <iostream>
#include <WSFault.h> /*I have replaced AxisFault.h by this file since the AxisFault does not exist anymore*/
#include <Environment.h>

using namespace std;
using namespace wso2wsf;

int main(int argc, char *argv[])
{
    Environment::initialize("hello.log", AXIS2_LOG_LEVEL_TRACE);

    string end_point = "http://localhost:9090/axis2/services/hello";

    ServiceClient sc(end_point);

    OMElement * payload = new OMElement("greet"); 
    payload->setText("Test service!");
    try
    {
           OMElement* response = sc.request(payload, "");
            if (response)
            {
                cout << endl << "Response: " << response << endl;
            }
        }
        catch (AxisFault & e)
        {
            if (sc.getLastSOAPFault())
            {
                cout << endl << "Fault: " << sc.getLastSOAPFault() << endl;
            }
            else
            {
                cout << endl << "Error: " << e << endl;
            }
        }
        delete payload;
    }

使用给定的编译命令行：

gcc -o hello_cli -I$WSFCPP_HOME/include/axis2-1.6.0/ -L$WSFCPP_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -lwso2_wsf hello_cli.cpp -ldl -Wl,--rpath -Wl,$WSFCPP_HOME/lib

我收到了这个错误：

hello_cli.cpp:19:27: fatal error: ServiceClient.h : No such file or directory

为了解决这个问题，我还包含了 ServiceClient 所在的目录：

gcc -o hello_cli -I$WSFCPP_HOME/include/ -I$WSFCPP_HOME/include/axis2-1.6.0/ -L$WSFCPP_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -lwso2_wsf --verbose hello_cli.cpp -ldl -Wl,--rpath -Wl,$WSFCPP_HOME/lib

这会导致以下错误（我只是提供一个示例）：

    hello_cli.cpp:(.text+0x23): undefined reference to `std::allocator<char>::allocator()'
hello_cli.cpp:(.text+0x3b): undefined reference to `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string(char const*, std::allocator<char> const&)'
hello_cli.cpp:(.text+0x4f): undefined reference to `wso2wsf::Environment::initialize(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, axutil_log_levels)'
hello_cli.cpp:(.text+0x5e): undefined reference to `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::~basic_string()'
hello_cli.cpp:(.text+0x6a): undefined reference to `std::allocator<char>::~allocator()'
hello_cli.cpp:(.text+0x76): undefined reference to `std::allocator<char>::allocator()'

通过使用 g++ 而不是 gcc（这似乎很自然，因为我正在操作 C++ 对象）我得到了以下信息。

命令行：

g++ -o hello_cli -I$WSFCPP_HOME/include/ -I$WSFCPP_HOME/include/axis2-1.6.0/ -L$WSFCPP_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -lwso2_wsf --verbose hello_cli.cpp -ldl -Wl,--rpath -Wl,$WSFCPP_HOME/lib

输出：

/tmp/cccyHkNn.o: In function `main':

hello_cli.cpp:(.text+0x4f): 未定义对wso2wsf::Environment::initialize(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, axutil_log_levels)' hello_cli.cpp:(.text+0xc0): undefined reference towso2wsf::ServiceClient::ServiceClient(std::basic_string, std::allocator >)' hello_cli.cpp:(.text+0x109) 的引用：未定义对wso2wsf::OMElement::OMElement(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)' hello_cli.cpp:(.text+0x159): undefined reference towso2wsf 的引用： :OMElement::setText(std::basic_string, std::allocator >)' hello_cli.cpp:(.text+0x1ac): 未定义对wso2wsf::ServiceClient::request(wso2wsf::OMElement*, std::basic_string<char, std::char_traits<char>, std::allocator<char> >)' hello_cli.cpp:(.text+0x234): undefined reference towso2wsf::ServiceClient::~ServiceClient()' hello_cli.cpp:(.text 的引用+0x36b): 未定义对wso2wsf::ServiceClient::getLastSOAPFault()' hello_cli.cpp:(.text+0x384): undefined reference towso2wsf::ServiceClient::getLastSOAPFault()' 的引用 hello_cli.cpp:(.text+0x411): 未定义对wso2wsf::ServiceClient::~ServiceClient()' /tmp/cccyHkNn.o:(.gcc_except_table+0xc4): undefined reference towso2wsf::WSFault 的 typeinfo 的引用'

我的操作系统是 Ubuntu 12.04.1 LTS（64 位），g++ 版本是 4.6.3（Ubuntu/Linaro 4.6.3-1ubuntu5）

由于 Mat 的评论，这个问题得到了解决

仅使用 g++ 编译和链接 C++，并将库 (-lfoo) 放在源文件和目标文件之后
