One simple facility for making porting easier that has been added in FLAC 1.1.3 is a set of
export.h of each library's includes (e.g.
#defines mirror the libraries' libtool version numbers, e.g. in libFLAC there are
FLAC_API_VERSION_AGE. These can be used to support multiple versions of an API during the transition phase, e.g.
#if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7 legacy code #else new code #endif
The the source will work for multiple versions and the legacy code can easily be removed when the transition is complete.
Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in include/FLAC/export.h), which can be used to determine whether or not the library has been compiled with support for Ogg FLAC. This is simpler than trying to call an Ogg init function and catching the error.
