Question

我正在Windows 10中使用NetBeans IDE 8.2（用于C / C +++）开发C ++应用程序（此应用程序的名称为 SGBD Rasore ），为此，我需要访问开发的数据库与Oracle 11g并由SQL Developer管理。为了简化工作，我想使用SQLAPI +++（http://www.sqlapi.com/）。我从http://www.sqlapi.com/Download/sqlapi_trial.exe下载了该库，并对其进行了解压缩（位于桌面上名为BD的文件夹中）。

在我的NetBeans项目中，我完成了以下操作：

Properties=>Build=>C++ Compiler=>Include Directories，我已经在此处写过../../../Desktop/BD/SQLAPI/include（标题为.h的位置）

Properties=>Build=>Linker=>Libraries，我从SQLAPI/MinGW-5.1.0-tdm64/lib

中添加了 libsqlapi.a

Properties=>Build=>Linker=>Additional Library Directories，我已经在那儿写过../../../Desktop/BD/SQLAPI/MinGW-5.1.0-tdm64/lib

编写#include <SQLAPI.h>时没有语法错误，也没有问题，但是，当我尝试执行从http://www.sqlapi.com/Examples/step1.cpp复制的下一个示例代码时：

#include <iostream>
#include <SQLAPI.h>

using namespace std;

int main() {
    SAConnection con; // create connection object
    cout << "Empieza el intento\n";
    try
    {
    // connect to database
    // in this example it is Oracle,
    // but can also be Sybase, Informix, DB2
    // SQLServer, InterBase, SQLBase and ODBC
    con.Connect(
            "pruebaRAUCM",     // database name
            "carmor06",   // user name
            "1234",   // password
            SA_Oracle_Client);

            cout << "We are connected!\n";

            // Disconnect is optional
            // autodisconnect will ocur in destructor if needed
            con.Disconnect();

            cout << "We are disconnected!\n";
    }
    catch (SAException &x)
    {
    // SAConnection::Rollback()
    // can also throw an exception
    // (if a network error for example),
    // we will be ready
    try
    {
        // on error rollback changes
        con.Rollback();
    }
    catch (SAException &)
    {
    }
    // print error message
    cout << "%s\n" << (const char*)x.ErrText();
    }
    return 0;
}

我收到此错误消息：

我应该怎么做才能解决此错误并能够运行该程序？有人可以一步一步向我解释吗？

预先感谢
