Compiling mysql connector C++ with mingw, compiling errors - c++

Question

I'm having a problem compiling mysql connectors C++ with mingw, as posted in the official website, you should run cmake to configure the source, then run a mingw32-make... the cmake needs to have the boost library installed, so i got it and compiled it (it says many updated, 40 targets skipped and failed to update 24).
After that tried to run cmake on mysql connector source, it output no errors and work just fine, when trying to do the final step mingw32-make, it gives lots of errors, many of then are redefinitions... the log is below. Please help me i really need it.

Answer 1

The mysql connector c++ source code is garbage, unfortunately.
It redefines functions that are defined in the standard library and then includes the standard library, or depends on non-standard functions that are not included in every implementation.
Since the standard library does not check to see if its functions and structs have already been defined, you end up with multiple definition errors all over the place.
Also, the problem is made worse for you in that mysql connector has not been ported for mingw. To compile on windows you are required to use visual studio.
It get's better. They only support visual studio 8 and 9.
If you follow these instructions exactly,
http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-installation-source-windows.html
then you might be able to get it to work, but you must not deviate from any version numbers. Use an old version of cmake, an old version of visual studio. They have not tested nor do they care about compatibility with any modern versions of build tools.
