程序启动时出错

当我尝试从Release文件夹启动程序时,操作系统会打开一个错误窗口,显示以下消息:

在动态链接库libstc ++中找不到该过程的入口点_gxx_personality_v0。dll

这是源代码:

#include <iostream> 
#include <stdio.h>
#include <cstring>
#include <string>
#include "tinyxml.h"

using namespace std;

void write_app_settings_doc( )  
{  
    TiXmlDocument doc;  
    TiXmlElement* msg;
    TiXmlDeclaration* decl = new TiXmlDeclaration( "1.0", "", "" );  
    doc.LinkEndChild( decl );  

    TiXmlElement * root = new TiXmlElement( "MyApp" );  
    doc.LinkEndChild( root );  

    TiXmlComment * comment = new TiXmlComment();
    comment->SetValue(" Settings for MyApp " );  
    root->LinkEndChild( comment );  

    TiXmlElement * msgs = new TiXmlElement( "Messages" );  
    root->LinkEndChild( msgs );
    TiXmlElement * deep = new TiXmlElement( "vector" );  
    msgs->LinkEndChild( deep );
    string array[4] = { "Bayer Leverkusen", "Sporting Lisboa", "Villareal", "Montpellier" };
    for(int i=0; i<4; i++) {
        TiXmlElement * items = new TiXmlElement( "item" );
        deep->LinkEndChild( items );
        const char* text = array[i].c_str();
        items->SetAttribute("id", i);
        items->LinkEndChild( new TiXmlText( text ));
    }
    msg = new TiXmlElement( "Welcome" );  
    msg->LinkEndChild( new TiXmlText( "Welcome to MyApp" ));  
    msgs->LinkEndChild( msg );  

    msg = new TiXmlElement( "Farewell" );  
    msg->LinkEndChild( new TiXmlText( "Thank you for using MyApp" ));  
    msgs->LinkEndChild( msg );  

    TiXmlElement * windows = new TiXmlElement( "Windows" );  
    root->LinkEndChild( windows );  

    TiXmlElement * window;
    window = new TiXmlElement( "Window" );  
    windows->LinkEndChild( window );  
    window->SetAttribute("name", "MainFrame");
    window->SetAttribute("x", 5);
    window->SetAttribute("y", 15);
    window->SetAttribute("w", 400);
    window->SetAttribute("h", 250);

    TiXmlElement * cxn = new TiXmlElement( "Connection" );  
    root->LinkEndChild( cxn );  
    cxn->SetAttribute("ip", "192.168.0.1");
    cxn->SetDoubleAttribute("timeout", 123.456); // floating point attrib

    doc.SaveFile("appsettings.xml");  
}

void Load() {
    TiXmlDocument *doc = new TiXmlDocument("appsettings.xml"); 
    doc->LoadFile();
    TiXmlElement* root = doc->FirstChildElement("MyApp");
    if (root) {
    TiXmlElement* msgs = root->FirstChildElement("Messages");
    TiXmlElement* input = msgs->FirstChildElement("vector");
    TiXmlNode* child;

        TiXmlElement* item_element = child->ToElement();

        }
    }
}

CodeLite 5.4 MinGW 4.8.1 Windows 7

答案 0 :(得分:0)

您可能有libstdc++6.dll个文件不匹配

P.S。您可以使用#include <cstdio>不要混合标题(有关差异的更多信息here)

答案 1 :(得分:0)

如果从codelite中运行它,请确保在路径中首先设置mingw 4.8.1 bin目录:

从codelite的主菜单: 设置 - &gt;环境变量

添加此行

PATH=/path/to/mingw481/bin;$PATH

在codelite外部运行时,只需复制可执行文件旁边的正确dll即可。

答案 2 :(得分:0)

解决:问题发生在Windows环境变量中:在“系统属性” - >“环境变量”(在Windows 7中,在我的情况下)两个%PATH%变量(一个用于您的帐户和系统 - 宽变量%PATH%)没有MinGW路径(在我的情况下为C:\ MinGW \ bin)。 这不是一个小问题:要正常工作,只需将tinyxml .cpp文件添加到工作区,并在预处理器中包含tinyxml.h。
