It is useful to be able to query the version number at compile time - particularly to accommodate differences in the API between versions. (I note that many other libraries provide the same; e.g., FFmpeg, OpenCV, zlib, etc.)

Please consider adding #defines major/minor/revision info in b2_settings.h

Please see extern B2_API b2Version b2_version; in b2_common.h

Hi, Erin.

The enhancement request is to be able to query the library version at COMPILE time, not run time. For example:

if BOX2D_MAJOR_VERSION > 2

Thanks. --Ted
