Mysql++ "undefined reference to __imp___ZN7mysqlpp10ConnectionC1Eb"
原标题:

I am trying to install the mysql++ in Code::Blocks, but When I try to run the example code I get this error:

undefined reference to __imp___ZN7mysqlpp10ConnectionC1Eb

What I am doing wrong?

You must build MySQL++ with the exact same compiler and compiler options as you re using to build your program. What you re seeing is a name mangling and/or ABI mismatch due to mixing compilers and/or build options. This can be anything from a drastic error like trying to use a Visual C++ DLL with MinGW, to something more subtle like trying to use a MinGW DLL built with g++ 3.4.5 in a program you re building with MinGW g++ 4.4.

Unlike C, C++ doesn t try to preserve binary compatibility between greatly different compilers.

You probably have a linker issue. It could well be that a DLL you need isn t present, or mysql++ was compiled but not correctly linked.
