I'm trying to use MySQL connector with Eclipse C/C++ to deploy an easy and small program where my DB returns a silly table, just to see how it works. But I always have different issues, I'll explain you what I did and the messages that Eclipse is showing me.

Could you help me? I'm pretty lost, every time I try to find a solution I end up with thousands of webs, links and references but none of the helps at all. I thought it was much easier to link Eclipse with MySQL :(

Hi ,

It has nothing to do with Eclipse CDT.

From the warnings (e.g. warning: ignoring #pragma warning [-Wunknown-pragmas]... "#pragma warning (disable : 4290)" and more pragma warnings ) and the error (error: conflicting declaration 'typedef long int int32_t'
typedef __int32 int32_t;) I deduce that the library you are using a MS Visual C++ library. But you are using MinGW (g++) .

In general you cannot use the C++-library compiled/linked with one compiler for the compilation/linking with another compiler. SO find a MinGW (g++) library for MySQL or use a plain C ODBC-type library.
