How to fix unresolved external symbol due to MySql Connector C++?

Question

I followed this tutorial http://blog.ulf-wendel.de/?p=215#hello. I tried both on Visual C++ 2008 and Visual C++ 2010. Either static or dynamic, the compiler gave me the same

Answer 1

I spent several hours trying to solve the problem exactly the same as you. I finally found out the problem myself. I downloaded the 64-bit version of MySQL/SQL Connector and followed a tutorial in MySQL.com in setting up win32 console project its properties and got the error message as mentioned. It was because the tutorial is teaching to build a 32-bit program. After I change to build a release version of X64 code, problem was solved. Make sure your library is 32bit or 64bit and then configure your Visual Studio accordingly (in configuration manager).

Answer 2

I solved using the 32bit version both for mysql server and connector/c++ on 64bit OS. I think the problem are the boost libraries but im not sure.
