connecteur MySQL/C++ ne fonctionne pas dans CodeBlocks

Question

J'ai installé le dernier connecteur MySQL/C++ 1.1.8 de ce site https://dev.mysql.com/downloads/connector/cpp/

c'est mon main.cpp

#include <iostream> 
#include <sstream> 
#include <memory> 
#include <string> 
#include <stdexcept> 
#include <stdlib.h>

using namespace std; 
using namespace sql; 
static void retrieve_data_and_print (ResultSet *rs, int type, int colidx, 
string colname) 

/* retrieve the row count in the result set */ 
cout << "\nRetrieved " << rs -> rowsCount() << " row(s)." << endl; 

cout << "\nTestColumnName" << endl; 
cout << "--------" << endl; 

/* fetch the data : retrieve all the rows in the result set */ 
while (rs->next()) { 
    if (type == NUMOFFSET) { 
        cout << rs -> getString(colidx) << endl; 
    } else if (type == COLNAME) { 
        cout << rs -> getString(colname) << endl; 
    } // if-else 
} // while 

cout << endl; 
} 

int main(int argc, const char *argv[]) { 
Driver *driver; 
Connection *con; 
Statement *stmt; 
ResultSet *res; 
PreparedStatement *prep_stmt; 
Savepoint *savept; 

int updatecount = 0; 

/* initiate url, user, password and database variables */ 
string url(argc >= 2 ? argv[1] : DBHOST); 
const string user(argc >= 3 ? argv[2] : USER); 
const string password(argc >= 4 ? argv[3] : PASSWORD); 
const string database(argc >= 5 ? argv[4] : DATABASE); 

try { 
    driver = get_driver_instance(); 
/* create a database connection using the Driver */ 
    con = driver -> connect(url, user, password); 

    /* turn off autocommit */ 
    con -> setAutoCommit(0); 

    cout << "Database connection\'s autocommit mode = " << con -> 
    getAutoCommit() << endl; 

    // select database schema 
    con -> setSchema(database); 

    // create a statement object 
    stmt = con -> createStatement(); 

    cout << "Executing Query: \"SELECT * FROM organizations\" ... " << endl; 

    /* run query */ 
    res = stmt -> executeQuery ("SELECT * FROM organizations"); 

    cout << "Retrieving the result set ..." << endl; 
    retrieve_data_and_print (res, NUMOFFSET, 1, string("TestColumnName")); 

} catch (SQLException &e) { 
    cout << "ERROR: SQLException in " << __FILE__; 
    cout << " (" << __func__<< ") on line " << __LINE__ << endl; 
    cout << "ERROR: " << e.what(); 
    cout << " (MySQL error code: " << e.getErrorCode(); 
    cout << ", SQLState: " << e.getSQLState() << ")" << endl; 

    if (e.getErrorCode() == 1047) { 
     /* 
     Error: 1047 SQLSTATE: 08S01 (ER_UNKNOWN_COM_ERROR) 
     Message: Unknown command 
     */ 
     cout << "\nYour server does not seem to support Prepared Statements 
    at all. "; 
     cout << "Perhaps MYSQL < 4.1?" << endl; 
    } 

    return EXIT_FAILURE; 
} catch (std::runtime_error &e) { 

    cout << "ERROR: runtime_error in " << __FILE__; 
    cout << " (" << __func__ << ") on line " << __LINE__ << endl; 
    cout << "ERROR: " << e.what() << endl; 

     return EXIT_FAILURE; 
    } 

    return EXIT_SUCCESS; 
} 

lorsque je tente de construire un exemple de code alors ce message d'erreur apparaît:

Le problème semble être dans les fichiers d'en-tête-de connecteur MySQL/c + +. L'erreur affichée par codeblocks est dans ces fichiers d'en-tête-

et cela aussi.

Cette erreur est généralement liée à MingW32 sur une machine 64 bits. Vous devez utiliser mingw64 http://mingw-w64.org/doku.php/download et définir correctement les exécutables Toolchain.
