The goal is to change the version number for a new release only in CMakeLists.txt. This is the first step. Details: - CMake/gen_config.cmake: this new file is included to generate the header files config.h (private, root directory), and FL/fl_config.h (public, can be installed). This file implements also ABI version checks (removed from FL/Enumerations.H and with more checks). Warnings are issued if the chosen ABI version is invalid. - CMake/export.cmake: code to generate 'config.h' was moved to CMake/gen_config.cmake. - CMake/options.cmake: set default of FLTK_BUILD_FORMS=OFF + comments - CMakeLists.txt: move generation of FL/fl_config.h to gen_config.cmake, add API and ABI versions to CMake summary, - FL/Enumerations.H: remove most of the version number details which are now included in FL/fl_config.h. This needed also some doxygen related changes. - README.CMake.txt: improve docs of FL_ABI_VERSION and some more. Reflect the new default of CMake option FLTK_BUILD_FORMS (OFF). - documentation/Doxyfile.in: add FL/fl_config.h to file list. This file is created in the build tree (and may be "installed"). - fl_config.h.in: add version number details that have been moved here from Enumerations.H (used to generate FL/fl_config.h).

FLTK defines some constants to help the programmer to

find out, for which FLTK version a program is compiled.

The following constants are defined:

/**
|
|
The FLTK ABI (Application Binary Interface) version number as an \em int.
|
|
|
|
FL_ABI_VERSION is an \em int that describes the major, minor, and patch
|
|
ABI version numbers in the same format as FL_API_VERSION.
|
|
|
|
The ABI version number \p FL_ABI_VERSION is usually the same as the
|
|
API version \p FL_API_VERSION with the last two digits set to '00'.
|
|
|
|
FLTK retains the ABI (Application Binary Interface) during patch
|
|
releases of the same major and minor versions. Examples:
|
|
|
|
\verbatim
|
|
FLTK Version FL_API_VERSION FL_ABI_VERSION FL_VERSION (deprecated)
|
|
1.3.0 10300 10300 1.0300
|
|
1.3.4 10304 10300 1.0304
|
|
\endverbatim
|
|
|
|
Version 1.2.3 is actually stored as 10203 to allow for more than 9 minor
|
|
and patch releases.
|
|
|
|
The FL_MAJOR_VERSION, FL_MINOR_VERSION, and FL_PATCH_VERSION constants
|
|
give the integral values for the major, minor, and patch releases
|
|
respectively.
|
|
|
|
To enable new ABI-breaking features in patch releases you can configure
|
|
FLTK to use a higher FL_ABI_VERSION. The highest allowed version is
|
|
|
|
FL_ABI_VERSION = FL_API_VERSION + 1
|
|
|
|
to allow for "next version" ABI features when FLTK is built from git or
|
|
from a snapshot (pre-release version).
