Several unresolved external errors

[Bastian Heinrich]

Hi guys,

I really need your help. I am trying for days now but I can't solve the probleme by myself.
I am trying to use the C++ Connector. I followed the example on the c++ conectors web page. I added the include directory to my project, I added the missing sqlstring file, I added the folder for the lib files and added the lib file mysqlcppconn-static.lib and the mysqllib.lib. Because I use the static library I added the Preprocessor directive: CPPCONN_PUBLIC_FUNC=.
I also installed boost and added the include directory for the boost-folder.

For my test I only use this code:

#include "stdafx.h"
#include "stdio.h"
#include "mysql_connection.h"
#include "mysql_driver.h"


int _tmain(int argc, _TCHAR* argv[])
{
sql::mysql::MySQL_Driver *driver;

driver = sql::mysql::get_mysql_driver_instance();
return 0;
}

And I get 126 errors. :(
If anybody has an idea, please let me know. Thank you very much for any advice.

Here are some examples (the error messages are in german):

Fehler 1 error LNK2001: Nicht aufgelöstes externes Symbol ""__declspec(dllimport) public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (__imp_??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@ABV01@@Z)". c:\Users\heinrich\documents\visual studio 2010\Projects\sqltestcpp\sqltestcpp\mysqlcppconn-static.lib(mysql_resultset_metadata.obj) sqltestcpp

Oh, and I used everything in Release mode.

Greetings, Basti
