One of the areas where pkg-config can cause some problems is when trying to cross compile some code, or when working with multi-arch systems (such as bi-arch AMD64 Linux distros). While it is possible to use pkg-config in such systems by manipulating $PKG_CONFIG_PATH and/or $PKG_CONFIG_LIBDIR, users can't just follow the instructions given for the single-arch case. After some discussion with Wolfgang Wieser, we came up with a proposal for better supporting cross-compile and multi-arch uses.

One of the things that pisses me off about gweather is that it occasionally hangs and stops updating. It is a bit easier to tell when this has occurred these days, since it is quite obvious something's wrong if gweather thinks it is night time when it clearly isn't. The current code uses gnome-vfs, which isn't the best choice for this sort of thing. The code is the usual mess you get when turning an algoithm inside out to work through callbacks in C:

One of the features added back in Python 2.2 was class methods. These differ from traditional methods in the following ways: They can be called on both the class itself and instances of the class. Rather than binding to an instance, they bind to the class. This means that the first argument passed to the method is a class object rather than an instance. For most intents and purposes, class methods are written the same way as normal instance methods.

I uploaded a few patches to the pkg-config bugzilla recently, which will hopefully make their way into the next release. The first is related to bug 3097, which has to do with the broken dependent library elimination code added to 0.17. The patch adds a Requires.private field to .pc files that contains a list of required packages like Requires currently does, which has the following properties: When verifying that a particular package name is available with "pkg-config --exists", dependencies in both Requires and Requires.

Phillip: your idea about direct client to client clipboard transfers is doable with the current X11 clipboard model: Clipboard owner advertises that it can convert selection to some special target type such as "client-to-client-transfer" or similar. If the pasting client supports client to client transfer, it can check the list of supported targets for the "client-to-client-transfer" target type and request conversion to that target. The clipboard owner returns a string containing details of how to request the data (e.

I put up a proposal for implementing anonymous voting for the foundation elections on the wiki. This is based in part on David's earlier proposal, but simplifies some things based on the discussion on the list and fleshes out the implementation a bit more. It doesn't really add to the security of the elections process (doing so would require a stronger form of authentication than "can read a particular email account"), but does anonymise the election results and lets us do things like tell the voter that their completed ballot was malformed on submission.

Found out about The Python Challenge. While you don't need to use Python to solve most of the problems, a knowledge of the language certainly helps. While the initial problems are fairly easy, some of the later ones are quite difficult, and cover many topics. If you decide to have a go, here are a few hints that might help: Keep a log of what you do. Solutions to may provide insight into subsequent problems.

Phillip: the majority of applications have no cut and paste code in them — they rely on the cut and paste behaviour of the standard widgets. Since the standard widgets like GtkEntry in GTK 2.6 mark their selections as being savable (in fact, any code that calls gtk_clipboard_set_text() will have its selection marked as savable). Most of the remaining cases are ones where you'd want to be selective in what gets saved (e.

This posting follows on from my previous postings about Bazaar, but is a bit more advanced. In most cases you don’t need to worry about this, since the tools should just work. However if problems occur (or if you’re just curious about how things work), it can be useful to know a bit about what’s going on inside. Changesets vs. Tree Snapshots A lot of the tutorials for Arch list “changeset orientation” as one of its benefits over other systems such as Subversion, which were said to be based on “tree snapshots”.

I've moved my diary over to blogs.gnome.org, which offers a few extra features over advogato (the main ones I'm interested in are more control over the layout, and the ability to embed images). Overall it seems pretty good, although I have a few gripes: The login cookie gets set for the path /nb.cgi/ only, so when I go to the front page of my diary, which is not under that path due to some mod_rewrite magic, it never thinks I'm logged in.

I got a few responses to the comparison between CVS, Subversion and Bazaar command line interfaces I posted earlier from Elijah, Mikael and David. As I stated in that post, I was looking at areas where the three systems could be compared. Of course, most people would choose Arch because of the things it can do with it that Subversion and CVS can't. Below I'll discuss two of those things: disconnected development and distributed development.

With the current discussion on gnome-hackers about whether to switch Gnome over to Subversion, it has been brought up a number of times that people can switch from CVS to Subversion without thinking about it (the implication being that this is not true for Arch). Given the improvements in Bazaar, it isn't clear that Subversion is the only system that can claim this benefit. For the sake of comparison, I'm considering the case of a shared repository accessed by multiple developers over SSH.

Shortly after the scandal over Cornelia Rau (a mentally ill Australian who was in detention for 10 months), another case gets some media attention: Vivian Young/Alvarez/Solon. She is an Australian citizen born in the Phillipines, who also suffers from a mental illness. From the news reports, the sequence of events seems to be: In 1984, Vivian moved to Australia to live with her new husband. In 2001, she was involved in a car accident in NSW.

Recently Bryan posted about background channels -- a system for automatic updating desktop wallpaper. One of the features of the design is a new URI scheme based on the same ideas as webcal://, which I think is a bad idea (as dobey has also pointed out). The usual reasoning for creating a URI scheme like this go something like this: You want to be able to perform some action when a link in a web page is clicked.

Ubuntu Down Under I have been in Sydney for the past week for UDU, which wraps up tomorrow. It has been great meeting up with everyone again, but has also been exhausting. Some of the stuff on the horizon will be quite ground breaking. For instance, I don't think anyone has attempted something like Grumpy Groundhog (which will hopefully be very useful to both the distro team, and upstream projects like Gnome).

One of the changes in the recent pkg-config releases is that the --libs output no longer prints out the entire list of libraries expanded from the requested set of packages. As an example, here is the output of pkg-config --libs gtk+-2.0 with version 0.15: -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangoxft-1.0 -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 And with 0.17.1: -lgtk-x11-2.0 If an application is compiled with the first set of -l flags, it will include DT_NEEDED tag for each of those libraries.

If you look at the bottom of Cadbury's website in the footer of the page, you find the following text: ..., and the colour purple are Cadbury Group trade marks in Australia. Apparently Cadbury believes they can trade mark a colour, and according to a story on the radio they've been sending out cease and desist letters to other small chocolate makers in Australia. It turns out that even though they are claiming it as a trade mark, they only have a pending application.

I recently pointed jhbuild's bootstrap module-set at the new releases of pkg-config, which seems to have triggered some problems for some people. In some ways, it isn't too surprising that some problems appeared, since there were two years between the 0.15 and 0.16 releases. When you go that long without testing from packages that depend on you, some incompatibilities are bound to turn up. However, Tollef has been doing a good job fixing the bugs and 0.

Tracing Python Programs I was asked recently whether there was an equivalent of sh -x for Python (ie. print out each statement before it is run), to help with debugging a script. It turns out that there is a module in the Python standard library to do so, but it isn't listed in the standard library reference for some reason. To use it, simply run the program like this: /usr/lib/python2.4/trace.py -t program.

roozbeh: the Fedora EULA probably isn't a GPL violation (I'm sure Red Hat has legal advice that it is okay). Section 1 says "This agreement does not limit User's rights under, or grant User rights that supersede, the license terms of any particular component". So the EULA explicitly says that it doesn't limit any rights you received under the GPL. Section 2 goes on to say that your rights to copy or modify individual components of the distro are covered by the respective license.

Eugenia's Article I find it amusing how Eugenia selectively quotes mailing list posts to create an article about how Gnome doesn't care about what users want, and then in a follow-up asks that people don't take her article out of context. New Gettext While looking at the new version of gettext, I noticed the libgettextpo library. Starting with the new 0.14.2 release, this library now includes a .po file writer as well as a parser.

South Africa I put up my photos from the trip to Cape Town online. Towards the end there are some photos I took while hiking up Table Mountain. Building Gnome It looks like with the Gnome 2.10 release, some packages fail to build from CVS if you are using a version of libtool older than 1.5.12. This is due to the way libtool verifies the version strings — in versions prior to 1.

From the conditions of residence at the place I'm staying: 5. Where appropriate the masculine gender shall include the feminine gender and vice versa and the singular shall include the plural.

When I woke up this morning, there was a lot of smoke in the air from the bush fire up in the hills east of Perth. The smoke is so thick that some buildings less than a kilometer away are only just visible. Also, sunlight filtering through the smoke gives everything a yellow tinge. It hasn't burnt down any houses yet, and hopefully the fire services will get it under control before it does.

On the gtk-doc-list mailing list, Matthias mentioned that the GraphViz license has been changed to the CPL (the same license as used for Eclipse), which is considered Free by both the FSF and OSI (although still GPL incompatible). This should remove the barriers that prevented it getting packaged by Linux distributions. Due to the previous licensing, RMS urged developers of GNU software to not even produce output in the form that the GraphViz tools use as input.
