linux qt中的gsoap未定义引用

Question

我正在尝试编译并运行我的第一个 gsoap。但是在我的 main() 中，我收到了 undefined reference to 错误。我在网上搜索，很多解决方案都是针对 Windows 的。我正在 Linux(CentOS) 中编程并使用 Qt ..

我的 .pro 文件是：

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp \
    stdsoap2.cpp \
    soapC.cpp \
    soapClient.cpp

HEADERS += \
    stdsoap2.h \
    soapStub.h \
    soapH.h \
    soapCountryInfoServiceSoapBindingProxy.h

我没有给出libgsoap++.a 的链接，因为我已经在我的项目中包含了stdsoap2。

错误信息是：

/.1/Projects/calisma/soapCountries/main.cpp:47: error: undefined reference to `__ns1__ListOfLanguagesByCode(soap*, _i__ListOfLanguagesByCode*, _i__ListOfLanguagesByCodeResponse*)'
:-1: error: collect2: ld returned 1 exit status

这是我的 main.cpp，我在__ns1__ListOfLanguagesByCode(soap, code, result); 行中遇到错误

main.cpp:

#include <iostream>
#include "CountryInfoServiceSoapBinding.nsmap"
#include "soapCountryInfoServiceSoapBindingProxy.h"

int main()
{
    CountryInfoServiceSoapBinding *countryObj;

    struct soap *soap = soap_new();

    countryObj = (CountryInfoServiceSoapBinding *)malloc(sizeof(CountryInfoServiceSoapBinding));

    if(countryObj == NULL)
    {
        std::cout << "Cannot allocate memory for countryobj";
        exit(EXIT_FAILURE);
    }

    _i__ListOfLanguagesByCode *code;

    code = (_i__ListOfLanguagesByCode *)malloc(sizeof(_i__ListOfLanguagesByCode));

    if(code == NULL)
    {
        std::cout << "Cannot Allocate Memory for code";
        exit(EXIT_FAILURE);
    }

    _i__ListOfLanguagesByCodeResponse *result;

    result = (_i__ListOfLanguagesByCodeResponse *)malloc(sizeof(_i__ListOfLanguagesByCodeResponse));

    if(result == NULL)
    {
        std::cout << "Cannot Allocate Memory for result";
        exit(EXIT_FAILURE);
    }

    code = (_i__ListOfLanguagesByCode *)("tur");

    __ns1__ListOfLanguagesByCode(soap, code, result);

    std::cout << "result = " << result << std::endl;

    return 0;
}

我无法弄清楚我的错误在哪里，或者我错过了哪一部分。基本上我想提供代码（在我的示例中是“tur”）并查看服务结果。

任何帮助将不胜感激。

编辑 2：

int __ns1__ListOfLanguagesByCode的定义，它位于"soapCountryInfoServiceSoapBindingProxy.h"内部

virtual int __ns1__ListOfLanguagesByCode(_i__ListOfLanguagesByCode *i__ListOfLanguagesByCode, _i__ListOfLanguagesByCodeResponse *i__ListOfLanguagesByCodeResponse) { return soap ? soap_call___ns1__ListOfLanguagesByCode(soap, endpoint, NULL, i__ListOfLanguagesByCode, i__ListOfLanguagesByCodeResponse) : SOAP_EOM; }

我认为在您的 .pro 文件中需要添加以下字符串： LIBS += -lgsoap
