get_driver_instance（）与Qt崩溃 [英] get_driver_instance() crashes with Qt

问题描述

我试图用Qt的用户MySQL连接器/ C ++，并花了几个小时拉我的头发一个问题。这里有一个SIMPLE代码来测试连接：

I'm trying to User MySQL Connector/C++ with Qt, and had spent hours pulling my hairs on a problem. Here's a SIMPLE code to test out the connection:

int main(int argc, char *argv[]) {
QCoreApplication a(argc, argv);
cout << "aa" << endl;
sql::Driver *driver;
try {
    driver = get_driver_instance();
} catch(exception &e) {
    cout << e.what() << endl;
}

cout << "aa" << endl;
return a.exec();

}

我使用的是Qt Creator，windows Vista，my .pro文件如下：

I'm using Qt Creator, windows Vista, my .pro file is as follow:

QT       += core
QT       += sql

QT       -= gui

TARGET = friendsDB

CONFIG   += console
CONFIG   -= app_bundle

LIBS += "C:\Program Files\MySQL\MySQL Connector C++ 1.0.5\lib\debug\mysqlcppconn.lib"
INCLUDEPATH += "C:\Program Files\MySQL\MySQL Connector C++ 1.0.5\include"

TEMPLATE = app


SOURCES += main.cpp

推荐答案

MySQL连接器：可能出现的一个问题是，当您用于构建您的应用程序的工具不兼容与用于
的工具构建MySQL连接器/ C ++的二进制版本。理想情况下，您需要使用用于构建MySQL Connector / C ++二进制文件的相同工具来构建应用程序。

From the documentation of MySQL Connector: "One problem that can occur is when the tools you use to build your application are not compatible with the tools used to build the binary versions of MySQL Connector/C++. Ideally you need to build your application with the same tools that were used to build the MySQL Connector/C++ binaries."

并且重复akira的问题：你使用QMYSQL驱动程序吗？

And to repeat the question of akira: Why don't you use the QMYSQL drivers?
