LFS - Openbox Configuration

I originally wrote the following before I put together the far more sensible popular dependencies post, which cut down the shit significantly. I leave this here therefore, as an example of the joys of dependency hell.

I decide I want to install the obconf program which lets me configure openbox from a gui, and obmenu which lets me configure openbox's menu from, drum roll, a gui. Shocker. So, lets start by having a look at the README in the latest version of obmenu:

REQUERIMENTS:

  python >= 2.3, pygtk, python-glade

OK, so we installed Python 2.6.4 for Firefox, so we just need the other two. Now, what about obconf. Great, there is nothing in the README file for obconf. However, if you go to the website for obconf here, you get this:

Compiling ObConf requires the following packages:

    GTK+ 2.x library and headers (development package)
    Glade 2.x library and headers (development package)
    Openbox 3.4 or above (the libraries development package if it is separate)

So, we have GTK and Openbox (it take a special kind of mind to decide to point out that the configuration software for openbox needs openbox to be installed). Not sure what this Glade thing is, but it echos the python-glade package needed for obconf. A ha! It is an interface designer. Interestingly, wikipedia has in in the same category of tools as MUI for the Amiga. The glade 2.x library is presumably the libglade package referred to in BLFS. Good news is we have previously installed both of its dependencies, libxml2 and GTK+2. Now, as far as I and Google can gather there is no such fucking thing as python-glade, so I am operating on the presumption that python-glade = Glade 2.x library = libglade.

wget http://ftp.gnome.org/pub/gnome/sources/libglade/2.6/libglade-2.6.4.tar.bz2
tar -jxvf libglade-2.6.4.tar.bz2
cd libglade-2.6.4
./configure --prefix=/usr &&
make
make check

Error, error, error and then I check the page and discover that one of the tests is supposed to fail. OK, hands up that was my fault.

make install
cd ..
rm -rvf libglade-2.6.4

So that should be all the dependencies sorted out for obconf. Next is obmenu. Let's start with pygtk. Its README file says this about dependencies:

Requirements
============
  * C compiler (GCC and MSVC supported)
  * Python 2.3.5 or higher
  * PyGObject 2.12.1 or higher
  * Glib 2.8.0 or higher
  * GTK+ 2.8.0 or higher (optional) or
    GTK+ 2.10.0 or higher for 2.10 API
    GTK+ 2.12.0 or higher for 2.12 API
    GTK+ 2.14.0 or higher for 2.14 API
    GTK+ 2.16.0 or higher for 2.16 API
  * libglade 2.5.0 or higher (optional)
  * pycairo 1.0.2 or higher (optional)
  * numpy (optional)

So, we obviously have GCC, we also have Python. We also have GTK+2 higher than all version listed there, as well as GLib (remember this is G(nome)Lib not G(nu)Libc). We have just installed libglade, so we are good to go. Not going to bother with the optional stuff. Lets just do this PyGObject thingy. In turn, it requires gobject-introspection, although it doesn't tell you that in its README. gobject-introspection in turn requires libiffi, according to BLFS.

wget ftp://sourceware.org/pub/libffi/libffi-3.0.8.tar.gz
tar -xzvf libffi-3.0.8.tar.gz
cd libffi-3.0.8
./configure --prefix=/usr &&
make
make install
cd ..
rm -rvf libffi-3.0.8

Actually installing gobject-introspection was a right pain in the arse. The one with instructions in BLFS at the time of writing (0.6.14) doesn't fucking work with pygobject 2.26.0 (which is the latest available at the time of writing), so I downloaded the latest version of this. Which doesn't fucking work with my version of Glib. Ah fuck. So it turns into a guessing game to find a version of gobject-introspection which works with my glib AND pygobject. Bastard. 0.9.5 works. Oh, hang on:

subprocess.CalledProcessError: Command '['/bin/sh', '../../libtool', '--mode=link', '--tag=CC', '--silent', 'gcc', '-o', '/dev/shm/gobject-introspection-0.9.5/tests/scanner/tmp-introspect696b_W/Regress-1.0', '-L.', 'libregress.la', '../../girepository/libgirepository-1.0.la', '-pthread', '-lgio-2.0', '-lgobject-2.0', '-lgmodule-2.0', '-lgthread-2.0', '-lrt', '-lglib-2.0', '/dev/shm/gobject-introspection-0.9.5/tests/scanner/tmp-introspect696b_W/Regress-1.0.o']' returned non-zero exit status 1

No it fucking doesn't. Right. Lets try to solve this from the other direction and find the version of pygobject that will fucking work with gobject-introspection 0.6.14. By the way, what the fuck is gobject-introspection. It sounds suspiciously like an arts student's 'kooky' first album.

wget http://ftp.gnome.org/pub/gnome/sources/gobject-introspection/0.6/gobject-introspection-0.6.14.tar.bz2
tar -xjvf gobject-introspection-0.6.14.tar.bz2
cd gobject-introspection-0.6.14
./configure --prefix=/usr --disable-tests &&
make
make check

make install
cd ..
rm -rvf gobject-introspection-0.6.14

It turns out that if you look at the publish date of 0.6.14 it is 3rd June 2010. If you then look at 2.21 of pygobject that was published on 12th July 2010. Hmmm. Probably too late. 2.20 was September 2009 so that will definitely work with 0.6.14. Good. Progress. I install 2.20.

Well it installed, but then when I came to the next step (pygtk), oh, holy fucking shitting bastard. When I then downloaded 2.22 of pygtk, its README file states, and I quote:

PyGObject 2.12.1 or higher

What do I have? I have 2.20 - look its right up there! But when ./configuring I got:

checking for PYGOBJECT... configure: error: Package requirements (pygobject-2.0 >= 2.21.3) were not met:

Cocksucker. So when it SAYS 2.12.1 or higher it actually means 2.21.3 or higher. Looks like some lazy bastard hasn't updated the README file doesn't it? After checking file dates ... if I drop back to 2.17 of pygtk that should sync with 2.20 of PyGObject that I have installed.

checking for PYGOBJECT... configure: error: Package requirements (pygobject-2.0 >= 2.16.1) were not met:

No package 'pygobject-2.0' found

Oh, jesus fuck give me strength. YES IT FUCKING IS. I try 2.21 of pygtk and I get exactly the same fucking, manifestly false, bullshit statement. Right. Lets try 2.21.3 of pygobject since pygtk seems to desire that above all other things.

checking for GLIB - version >= 2.22.4... yes (version 2.22.4)

Man, that is cutting things pretty god damned fine. And does it fucking work? Does it fuck. Right, lets try exactly 2.16.1 of pygobject.

wget http://ftp.gnome.org/pub/GNOME/sources/pygobject/2.16/pygobject-2.16.1.tar.bz2
tar -xjvf pygobject-2.16.1.tar.bz2
cd pygobject-2.16.1
./configure --prefix=/usr
make
make install
cd ..
rm -rvf pygobject-2.16.1

Now for pygtk 2.17 again ...

checking for PYCAIRO... no
no
not checking for gtk due to missing pycairo
checking for GDK target... x11
configure: WARNING: Could not find a valid numpy installation, disabling.
checking whether gcc understands -Wall... yes
checking whether gcc understands -fno-strict-aliasing... yes
checking whether gcc understands -std=c9x... yes
configure: error: conditional "HAVE_GTK_2_16" was never defined.
Usually this means the macro was only invoked conditionally.

God fucking damn cunting it. PYCAIRO is supposed to be a fucking optional package.
* pycairo 1.0.2 or higher (optional)
See - OPTIONAL. Right.

wget http://cairographics.org/releases/py2cairo-1.8.10.tar.gz
tar -xzvf py2cairo-1.8.10.tar.gz
cd pycairo-1.8.10
./configure --prefix=/usr
make
make install
cd ..
rm -rvf pycairo-1.8.10

wget http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.17/pygtk-2.17.0.tar.bz2
tar -xjvf pygtk-2.17.0.tar.bz2
cd pygtk-2.17.0
./configure --prefix=/usr
make
make install
cd ..
rm -rvf pygtk-2.17.0

Well, at fucking last. Lesson? PYCairo is NOT FUCKING OPTIONAL. Probably all the other versions of pygtk were stalling on this as well, so my install is now completely unnecessarily retarded. Bastard.

wget http://prdownloads.sourceforge.net/obmenu/obmenu-1.0.tar.gz?download
tar -xzvf obmenu-1.0.tar.gz
cd obmenu-1.0
python setup.py install
cd ..
rm -rvf obmenu-1.0

Amazingly obmenu installed and is functional after all that shite. On the other hand obconf does not fucking work because Startup Notification has not been installed - boo fucking hoo. Bastard arseholes. This wasn't mentioned anywhere in its README of course.

wget http://ftp.gnome.org/pub/gnome/sources/startup-notification/0.9/startup-notification-0.9.tar.bz2
tar -xjvf startup-notification-0.9.tar.bz2
cd startup-notification-0.9
./configure --prefix=/usr &&
make
make install &&
install -v -m644 -D doc/startup-notification.txt /usr/share/doc/startup-notification-0.9/startup-notification.txt
cd ..
rm -rvf startup-notification-0.9

wget http://openbox.org/dist/obconf/obconf-2.0.3.tar.gz
tar -xzvf obconf-2.0.3.tar.gz
cd obconf-2.0.3
./configure --prefix=/usr
make
make install
cd ..
rm -rvf obconf-2.0.3

And, fucking hell, they both now work. That was not fun.

By way of summary, the follow packages turned out to be needed:

(GTK+2, Python, libxml2)

obmenu <-- libglade
       <-- pygtk <-- pygobject <-- gobject-introspection <-- libffi
                 <-- pycairo
obconf <-- libglade
       <-- startup-notification
