Raw Normal View History

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

1. Version and Release numbers
------------------------------
For each new public release of FreeType 2, there are generally *three*
distinct `version' numbers to consider:
* The official FreeType 2 release number, like 2.3.1 or 2.4.10.
* The libtool (and Unix) specific version number, like 13.0.7. This
is what `freetype-config --version' returns.
* The platform-specific shared object number, used for example when
the library is installed as `/usr/lib/libfreetype.so.6.7.1'.
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.
2. History
----------
The following table gives, for all releases since 2.3.0, the
corresponding libtool number, as well as the shared object number found
on _most_ systems, but not all of them:

* Version 2.1.7 released. ========================= * builds/unix/ft2unix.h: Fix comments. * builds/unix/ftconfig.in: Synchronized with ANSI version. Use `#undef' in templates as recommended in the autoconf documentation. Since real `#undef' lines don't survive during configuration, use `/undef' instead; the postprocessing facility of the AC_CONFIG_HEADERS autoconf macro converts them to `#undef'. * builds/unix/install.mk (install): Install Unix version of `ftconfig.h'. * builds/unix/unix-cc.in (CFLAGS): Set FT_CONFIG_CONFIG_H macro to include the correct `ftconfig.h' file. * builds/unix/ft-munmap.m4 (FT_MUNMAP_DECL): Removed. (FT_MUNMAP_PARAM): Updated syntax to autoconf 2.59. * builds/unix/freetype2.m4: Updated syntax to autoconf 2.59. * builds/unix/configure.ac: Use AC_CONFIG_HEADERS instead of AC_CONFIG_HEADER to create ftconfig.h, and use second argument to replace `/undef' with `#undef'. Don't use FT_MUNMAP_DECL but AC_CHECK_DECLS to check for munmap. Use AS_HELP_STRING in AC_ARG_WITH. Update syntax to autoconf 2.59. * builds/unix/ltmain.sh: Regenerated with `libtoolize --force --copy' from libtool 1.5. * builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from automake 1.7.8. * builds/unix/configure: Regenerated with autoconf 2.59. * builds/unix/config.guess, builds/unix/config.sub: Updated from `config' CVS module at subversions.gnu.org * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from `texinfo' CVS module at subversions.gnu.org. * builds/vms/ftconfig.h: Synchronized with ANSI version. * docs/CUSTOMIZE: Fix documentation error. * docs/CHANGES, docs/VERSION.DLL, docs/release: Updated. * builds/freetype.mk (refdoc): Updated --title.

3. Autoconf Code Fragment
-------------------------
Lars Clausen contributed the following autoconf fragment to detect which
version of FreeType is installed on a system. This one tests for a
version that is at least 2.0.9; you should change it to check against
other release numbers.
