Version Information
Version Information
GLib provides version information, primarily useful in configure checks for builds that have a configure script. Applications will not typically use the features described here.
Run-time Version Numbers
The variables glib_major_version, glib_minor_version, glib_micro_version,
glib_binary_age and glib_interface_age are all available to check.
They can be compared using the function glib_check_version().
Compile-time Version Numbers
Version Numbers
The GLib headers annotate deprecated APIs in a way that produces
compiler warnings if these deprecated APIs are used. The warnings
can be turned off by defining the macro GLIB_DISABLE_DEPRECATION_WARNINGS
before including the glib.h header.
GLib also provides support for building applications against
defined subsets of deprecated or new GLib APIs. Define the macro
GLIB_VERSION_MIN_REQUIRED to specify up to what version of GLib
you want to receive warnings about deprecated APIs. Define the
macro GLIB_VERSION_MAX_ALLOWED to specify the newest version of
GLib whose API you want to use.
The macros GLIB_VERSION_2_2, GLIB_VERSION_2_4, …, GLIB_VERSION_2_80, etc.
are defined automatically in each release, and can be used to set the value
of macros like GLIB_VERSION_MIN_REQUIRED.
The macros GLIB_VERSION_CUR_STABLE and GLIB_VERSION_PREV_STABLE are also
automatically defined to point to the right version definitions.
