C++ & MySQL - I NEED URGENT HELP (no replies)

Hi all,

I use MySQL with Java for years, and it's all straightforward and easy.
Now a client ask me to develop a very simple application, but he impose the use of C++ with MySQL, because he's developers are all C++ experts, but they don't have any skills with any DBMS (they don't even know SQL basics).

In the beginning I've tried to run examples that i found by googling, such as:

http://dev.mysql.com/doc/refman/5.6/en/connector-cpp-examples-complete-example-1.html

http://dev.mysql.com/doc/refman/5.6/en/connector-cpp-examples-complete-example-2.html

... and ...

http://blog.ulf-wendel.de/?p=215

No one of the three examples work, and I get dozens of errors in both the compile time and link time


So, my last hope was to wrote a do-nothing program just as follows:

// ====================

// C++ MySQL.cpp : Defines the entry point for the console application.
//

// in the boost libraries site they say "don't use pre-compiled headers
// so, I comment the next line
// #include "stdafx.h"
// however, with pre-compiled headers, the errors are the same


/* Standard C++ includes */
#include <stdlib.h>
#include <iostream>

/*
Include directly the different
headers from cppconn/ and mysql_driver.h + mysql_util.h
(and mysql_connection.h). This will reduce your build time!
*/
#include "mysql_connection.h"

#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>

using namespace std;

int main(void)
{
return 0;
}

// ====================

In the settings for the compiler and linker, I indicate the paths to the "includes" and "libraries" properly.

I build and ran the do-nothing program, and I get 3 warnings and 2 errors:

Warning 1:
warning C4251: 'sql::SQLString::realStr' : class 'std::basic_string<_Elem,_Traits,_Ax>' needs to have dll-interface to be used by clients of class 'sql::SQLString'

Error 5:

I use VC++ 2010 Express and MySQL Community Server 5.5.15
Because my OS is Windows 7 64-bit, I've tryed both 32 and 64 bit versions of MySQL Server and MySQL Connector/C++ 1.1.0

I've read in http://dev.mysql.com/downloads/connector/cpp/ that "A better solution is to build your MySQL Connector/C++ libraries from the source code, using the same tools that you use for building your application. This ensures compatibility."

Now the HUGE PROBLEM:

The process of build the connector has a degree of difficulty, that is out of my skills.

Can someone help me? Is there any connector pre-built for VC++ 2010 Express?
Should I use the connector for C instead of C++?
If I use the connector for C instead of C++, the problems persist?

I'll appreciate the help that you can give me. I can't quit the project they ask me.

Thank you in advance
