Chapter 6 Connector/C++ Known Issues

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 cause problems. If you obtain error messages that you suspect are related to binary incompatibilities, build Connector/C++ from source, using the same compiler and linker that you use to build and link your application.

Due to variations between Linux distributions, compiler versions, linker versions, and STL versions, it is not possible to provide binaries for every possible configuration. However, Connector/C++ binary distributions include an INFO_BIN file that describes the environment and configuration options used to build the binary versions of the connector libraries. Binary distributions also include an INFO_SRC file that provides information about the product version and the source repository from which the distribution was produced. (Prior to Connector/C++ 8.0.14, look for BUILDINFO.txt rather than INFO_BIN and INFO_SRC.)

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