When linking against a static library for 1.0.3 on Windows you need to define CPPDBC_PUBLIC_FUNC either in the compiler options (preferable) or with /D "CPPCONN_PUBLIC_FUNC=". You can also explicitly define it in your code by placing #define CPPCONN_PUBLIC_FUNC before the header inclusions.

Generally speaking C++ library binaries are less portable than C library binaries. Issues can be caused by name mangling, different Standard Template Library (STL) versions and using different compilers and linkers for linking against the libraries than were used for building the library itself.

Even a small change in the compiler version can, but does not have to, cause problems. If you obtain error messages, that you suspect are related to binary incompatibilities, build MySQL Connector/C++ from source, using the same compiler and linker that you will use to build and link your application.

Due to the variations between Linux distributions, compiler and linker versions and STL versions, it is not possible to provide binaries for each and every possible configuration. However, the MySQL Connector/C++ binary distributions contain a README file that describes the environment and settings used to build the binary versions of the libraries.

To avoid potential crashes the build configuration of MySQL Connector/C++ should match the build configuration of the application using it. For example, do not use the release build of MySQL Connector/C++ with a debug build of the client application.
