Re: New lgi dependency and older Ubuntu LTS
2012/6/17 Uli Schlachter psyc...@znc.in: Short version: You need /usr/lib/girepository-1.0/Pango-1.0.typelib (in debian this is in package gir1.2-pango-1.0). Uli, you are absolutely great. Now I not only have my awesome working again, but I understand the whole 'introspection' thing :) Thank you! For future reference: in Gentoo you need to have x11-libs/pango built with USE='introspection' BR, Paweł -- To unsubscribe, send mail to awesome-unsubscr...@naquadah.org.

Sounds like we shouldn't release 3.5 before then. ;-) Awesome already used Pango before and Pango used gobject before. The only new dependency (besides lgi) should be on gobject-introspection. Version 0.10.8 was releases in May 2011. That's a little more recent than I had thought. However, I have no good idea what could be done about this. I don't know what's new in gobject-introspection 0.10.8 and thus can't say why older versions don't work. Sounds like someone (I?) should write a mail to lgi upstream and ask for details... No need to, upstream is here and listening :-) Ubuntu Lucid supports only 0.6 series of gobject-introspection. Thats pretty bad, because so many bugfixes, many useful API additionas and even a few API/ABI changes were done since then. Current lgi code basically depends on gobject-introspection=1.30, with hacks added here and there to support goi=0.10 version. I was hoping to nuke those hacks in the next release, but it looks that I'll have to keep them. As for supporting 0.6.x series; almost definitely impossible with current lgi sourcebase. I'm having my small personal summer of code project, rewriting a lot of lgi internals, and (for unrelated reasons) it should lessen the dependency on exact version of gobject-introspection, so that 0.6.x could be usable (with some additional effort). But don't hold your breath, it might take a few months before I get it into the releasable shape. As Uli said above, installing newer gobject-introspection into the $HOME will probably not work, I'm afraid that .typelib files (coming from other packages) will not be compatible with it. The only solution would be to build locally (into your $HOME) the Gnome stack parts up to pango (which would also include gobject-introspection). Gnome's jhbuild[0] makes this quite a painless experience (at least for me it was). sorry for not so good news, Pavel [0] http://developer.gnome.org/jhbuild/unstable -- To unsubscribe, send mail to awesome-unsubscr...@naquadah.org.

New lgi dependency and older Ubuntu LTS
Hi everyone, I like tracking the git branch of awesome, but it has recently failed to compile for me after the switch to lgi: commit ca2fc7811ad769cc88ead583e099230f33f6c8a2 Author: Uli Schlachter psyc...@znc.in Date: Tue Jun 5 16:22:04 2012 +0200 gears.surface: Add a version check for lgi The cairo bindings are quite new in lgi and thus we depend on a quite new version of lgi. Older versions will fail with lots of weird errors, e.g.: lib/gears/color.lua:61:attempt to call field 'create_rgba' (a nil value) Signed-off-by: Uli Schlachter psyc...@znc.in Some of the dependencies of the lgi code cannot be met at all on my aging Ubuntu installation. I can't install the latest and greatest packages available on this system. Does this mean I cannot run awesome-master anymore?

I used to run awesome from git/master until about last week, but then it grew a dependency on lgi, and lgi depends in turn on gobject-introspection = 0.10.8. But this version of gobject-introspection is not available at all on my release. What my main question is I guess goes like this: - This seems to have added a dependency (indirect, through lgi, but still a dependency) of awesome to GTK+ or Gnome stuff with very specific version constraints. - If that's the case, is there any way to build _without_ the features that depend on lgi and gobject-introspection? -- To unsubscribe, send mail to awesome-unsubscr...@naquadah.org.

Ah, OK, I was just wondering if there was another change that I have not noticed :) Anyway, I have just tried running the latest version from git and it fails with the following: /usr/local/share/lua/5.1/lgi/namespace.lua:149: Typelib file for namespace 'Pango' (any version) not found /etc/xdg/awesome/rc.lua:2: loop or previous error loading module 'awful' E: awesome: main:555: couldn't find any rc file Is it happening because of some intensive work-in-progress in the repository and I just need to be more patient or do I need to adjust something on my system? I am using lua-5.1 and lgi compiled manually from git sources. Short version: You need /usr/lib/girepository-1.0/Pango-1.0.typelib (in debian this is in package gir1.2-pango-1.0). Long version: The gi in lgi means gobject introspection. The old oocairo and oopango handwritten code and every single function needed to be bound by hand. Cumbersome. The gobject API is supposed to be introspectable. That means that you can write a program which gets a description of which functions are there and which argument they take. This program can then call these functions. This is especially useful for language bindings like lgi. Instead of having to write the binding by hand, gobject introspection is used to figure out which objects, functions etc exist and the binding for them is created automatically[0]. Since I were the one who had to write the binding in oocairo by hand, I love this approach. :-) Your problem now seems to be that the description of which functions exist in Pango is missing and thus lgi can't do its gobject-magic. Uli [0]: Well, it's not perfect. lgi contains overrides which extend the introspectable API with extra stuff. Some of these functions aren't introspectable (yet) and thus can't be auto-generated, some of this works around bugs in the introspection information and some of this describes stuff which GIR can't express (yet?). -- - He made himself, me nothing, you nothing out of the dust - Er machte sich mir nichts, dir nichts aus dem Staub -- To unsubscribe, send mail to awesome-unsubscr...@naquadah.org.
