Version & Release numbers ----------------------------- - -For each new public release of FreeType 2, there are generally *three* -distinct "version" numbers to consider: - - * The official FT2 release number, like 2.0.9, or 2.1.3. - - * The libtool (and Unix) specific version number, like "9.2.3". This - is what "freetype-config --version" will return. - - * The platform-specific shared object number, used for example when - the library is installed as "/usr/lib/libfreetype.so.6.3.2". - -The platform-specific number is, unsurprisingly, platform-specific and -varies with the operating system you are using (several variants of -Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even -for simple tests. - -The libtool-specific number does not equal the release number but is -tied to it. - -The release number is available at *compile* time through the following -macros defined in FT_FREETYPE_H: - - - FREETYPE_MAJOR : major release number - - FREETYPE_MINOR : minor release number - - FREETYPE_PATCH : patch release number - -See below for a small autoconf fragment. - -The release number is also available at *runtime* through the -"FT_Library_Version" API.
