General Information
|
|
===================
|
|
|
|
This is GLib version @GLIB_VERSION@. GLib is the low-level core
|
|
library that forms the basis for projects such as GTK+ and GNOME. It
|
|
provides data structure handling for C, portability wrappers, and
|
|
interfaces for such runtime functionality as an event loop, threads,
|
|
dynamic loading, and an object system.

Installation
|
|
============
|
|
|
|
See the file 'INSTALL'
|
|
|
|
Notes about GLib-2.2.0
|
|
======================
|
|
|
|
* GLib changed the seeding algorithm for the pseudo-random number
|
|
generator Mersenne Twister, as used by GRand and GRandom. This was
|
|
necessary, because some seeds would yield very bad pseudo-random
|
|
streams. Further information can be found at:
|
|
|
|
http://www.math.keio.ac.jp/~matumoto/emt.html
|
|
|
|
Also the pseudo-random integers generated by g_rand_int_range and
|
|
g_random_int_range will have a slightly better equal distribution
|
|
with the new version of GLib.
|
|
|
|
The original algorithms, as found in GLib-2.0.x, can be used instead
|
|
of the new ones by setting the environment variable G_RANDOM_VERSION
|
|
to the value of "2.0".
|
|
|
|
Use the GLib-2.0 algorithms only if you have sequences of numbers
|
|
generated with Glib-2.0 that you need to reproduce exactly.
|
|
|
|
How to report bugs
|
|
==================
|
|
|
|
Bugs should be reported to the GNOME bug tracking system.
|
|
(http://bugzilla.gnome.org, product glib.) You will need
|
|
to create an account for yourself.
|
|
|
|
In the bug report please include:
|
|
|
|
* Information about your system. For instance:
|
|
|
|
- What operating system and version
|
|
- For Linux, what version of the C library
|
|
|
|
And anything else you think is relevant.
|
|
|
|
* How to reproduce the bug.
|
|
|
|
If you can reproduce it with the testgtk program that is built
|
|
in the gtk/ subdirectory, that will be most convenient. Otherwise,
|
|
please include a short test program that exhibits the behavior.
|
|
As a last resort, you can also provide a pointer to a larger piece
|
|
of software that can be downloaded.
|
|
|
|
* If the bug was a crash, the exact text that was printed out
|
|
when the crash occured.
|
|
|
|
* Further information such as stack traces may be useful, but
|
|
is not necessary.
|
|
|
|
Patches
|
|
=======
|
|
|
|
Patches should also be submitted to bugzilla.gnome.org. If the
|
|
patch fixes an existing bug, add the patch as an attachment
|
|
to that bug report.
|
|
|
|
Otherwise, enter a new bug report that describes the patch,
|
|
and attach the patch to that bug report.
|
|
|
|
Bug reports containing patches should include the PATCH keyword
|
|
in their keyword fields. If the patch adds to or changes the GLib
|
|
programming interface, the API keyword should also be included.
|
|
|
|
Patches should be in unified diff form. (The -u option to GNU
|
|
diff.)
