This commit pushes --disable-glib to the extreme of embedding the par of glib cogl depends on in tree to be able to generate a DSO that does not depend on an external glib. To do so, it: - keeps a lot of glib's configure.ac in as-glibconfig.m4 - pulls the code cogl depends on and the necessary dependencies Reviewed-by: Robert Bragg <robert@linux.intel.com>

* g_atexit:

* @func: (scope async): the function to call on normal program termination.
|
|
*
|
|
* Specifies a function to be called at normal program termination.
|
|
*
|
|
* Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
|
|
* macro that maps to a call to the atexit() function in the C
|
|
* library. This means that in case the code that calls g_atexit(),
|
|
* i.e. atexit(), is in a DLL, the function will be called when the
|
|
* DLL is detached from the program. This typically makes more sense
|
|
* than that the function is called when the GLib DLL is detached,
|
|
* which happened earlier when g_atexit() was a function in the GLib
|
|
* DLL.
|
|
*
|
|
* The behaviour of atexit() in the context of dynamically loaded
|
|
* modules is not formally specified and varies wildly.
|
|
*
|
|
* On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
|
|
* loaded module which is unloaded before the program terminates might
|
|
* well cause a crash at program exit.
|
|
*
|
|
* Some POSIX systems implement atexit() like Windows, and have each
|
|
* dynamically loaded module maintain an own atexit chain that is
|
|
* called when the module is unloaded.
|
|
*
|
|
* On other POSIX systems, before a dynamically loaded module is
|
|
* unloaded, the registered atexit functions (if any) residing in that
|
|
* module are called, regardless where the code that registered them
|
|
* resided. This is presumably the most robust approach.
|
|
*
|
|
* As can be seen from the above, for portability it's best to avoid
|
|
* calling g_atexit() (or atexit()) except in the main executable of a
|
|
* program.
