| michael@0 | 1 | Due to our use of `libtool' to generate and install the FreeType 2 |
| michael@0 | 2 | libraries on Unix systems, as well as other historical events, it is |
| michael@0 | 3 | generally very difficult to know precisely which release of the font |
| michael@0 | 4 | engine is installed on a given system. |
| michael@0 | 5 | |
| michael@0 | 6 | This file tries to explain why and to document ways to properly detect |
| michael@0 | 7 | FreeType on Unix. |

| michael@0 | 10 | 1. Version and Release numbers |
| michael@0 | 11 | ------------------------------ |
| michael@0 | 12 | |
| michael@0 | 13 | For each new public release of FreeType 2, there are generally *three* |
| michael@0 | 14 | distinct `version' numbers to consider: |
| michael@0 | 15 | |
| michael@0 | 16 | * The official FreeType 2 release number, like 2.3.1 or 2.4.10. |
| michael@0 | 17 | |
| michael@0 | 18 | * The libtool (and Unix) specific version number, like 13.0.7. This |
| michael@0 | 19 | is what `freetype-config --version' returns. |
| michael@0 | 20 | |
| michael@0 | 21 | * The platform-specific shared object number, used for example when |
| michael@0 | 22 | the library is installed as `/usr/lib/libfreetype.so.6.7.1'. |
| michael@0 | 23 | |
| michael@0 | 24 | The platform-specific number is, unsurprisingly, platform-specific and |
| michael@0 | 25 | varies with the operating system you are using (several variants of |
| michael@0 | 26 | Linux, FreeBSD, Solaris, etc.). You should thus _never_ use it, even |
| michael@0 | 27 | for simple tests. |
| michael@0 | 28 | |
| michael@0 | 29 | The libtool-specific number does not equal the release number but is |
| michael@0 | 30 | tied to it. |
| michael@0 | 31 | |
| michael@0 | 32 | The release number is available at *compile* time through the following |
| michael@0 | 33 | macros defined in FT_FREETYPE_H: |
| michael@0 | 34 | |
| michael@0 | 35 | - FREETYPE_MAJOR: major release number |
| michael@0 | 36 | - FREETYPE_MINOR: minor release number |
| michael@0 | 37 | - FREETYPE_PATCH: patch release number |
| michael@0 | 38 | |
| michael@0 | 39 | See below for a small autoconf fragment. |
| michael@0 | 40 | |
| michael@0 | 41 | The release number is also available at *runtime* through the |
| michael@0 | 42 | `FT_Library_Version' API. |
| michael@0 | 43 | |

| michael@0 | 45 | 2. History |
| michael@0 | 46 | ---------- |
| michael@0 | 47 | |
| michael@0 | 48 | The following table gives, for all releases since 2.3.0, the |
| michael@0 | 49 | corresponding libtool number, as well as the shared object number found |
| michael@0 | 50 | on _most_ systems, but not all of them: |

| michael@0 | 88 | ------------------------- |
| michael@0 | 89 | |
| michael@0 | 90 | Lars Clausen contributed the following autoconf fragment to detect which |
| michael@0 | 91 | version of FreeType is installed on a system. This one tests for a |
| michael@0 | 92 | version that is at least 2.0.9; you should change it to check against |
| michael@0 | 93 | other release numbers. |
