[提问]调用第三方动态链接库，程序异常退出，请问是什么问题？ [复制链接]

配置：Qt5.9 MinGW_32bit
调用添加：HEADERS += \        dialog.h \        Coredll/SynPublic.h \    ui_dialog.h
FORMS += \        dialog.ui
LIBS += \    SynIDCardAPI.dll \    SynIDCardAPI.lib
问题：Starting D:\Qt\Qt Practice\build-IdCardmain2-Desktop_Qt_5_9_0_MinGW_32bit-Debug\debug\IdCardmain2.exe...
程序异常结束。
D:\Qt\Qt Practice\build-IdCardmain2-Desktop_Qt_5_9_0_MinGW_32bit-Debug\debug\IdCardmain2.exe crashed.


代码如下：#include "dialog.h"#include "ui_dialog.h"

extern "C"{    #include "Coredll/SynPublic.h"}

#include <QMessageBox>#include <QCloseEvent>#include <QDebug>#include <QProcess>#include <QSettings>
Dialog::Dialog(QWidget *parent) :    QDialog(parent),    ui(new Ui::Dialog){    ui->setupUi(this);}
Dialog::~Dialog(){    delete ui;}
void Dialog::on_pushButton_clicked()//巡卡{    int iRet;    int iPort;    int portOpen;
    iPort=1001;//usb接口1001    portOpen=0;    if(portOpen==0)    {          qDebug()<<'iRet';        iRet=Syn_OpenPort(iPort);        ui->textEdit->setText("打开端口""失败，返回值为：");
    }}

Syn_OpenPort 这个函数导致的内存泄露吧，如果有源码，建议查看一下参数的限制~

可能是第三方库里面崩了，找他们解决。
