Re: GTK DBF IRC meeting (was: GTK DBF - Automatic build infrastructure)

[Attilio Fiandrotti <fiandro@tiscalinet.it>]

Here i reply to the quoted mail and to your previous "Re: GTK DBF - 
Automatic build infrastructure".
To summarize, you said we should use as much as possible, official 
udebs, then try to pack into udebs what's not available as official 
udebs and, eventually, use tarballs for those files where packaging is 
not possible/convenient.

Note that the d-i_dfb.tar.gz testcase i historycaly used for testing the 
FE and to build the experimental netinst ISOs already includes files 
provided by existing official udebs.
Since we want progegessively move from hacky solutions to complete udeb 
usage we'll need to include inside the initrd the following official udebs


*Official udebs to be included in th initrd

DirectFB:      libdirectfb-0.9-22-udeb (0.9.22-6)
GLib:          libglib2.0-udeb (2.8.0-1)
Pango:         libpango1.0-udeb    (1.8.2-1)
ATK:           libatk1.0-udeb (1.10.1-2)
LibPNG:        libpng12-0-udeb (1.2.8rel-1.0.1)
Mouse support: mouse-modules-2.6.12-1-386-di (or whatever is appropriate 
for the used kernel)
FontConfig:    fontconfig-udeb (2.3.2-1)
LibFreeType:   libfreetype6-udeb (2.1.10-1)
LibExPat:      libexpat1-udeb (1.95.8-3)


*Files provided by those udebs should then NOT be included inside the 
hypotetical "d-i_gtk_root.tar.gz" from where they will be removed.
After the cleanup then "d-i_gtk_root.tar.gz" will only contain

-libc-2.3.5.so, libpthread-0.10.so, ld-2.3.5.so( to be copied in /lib)
-Libraries and files once proveded by the no-longer existing 
libgtk+2.0-directfb0-udeb (until alastair will provide us again the 
missing udeb - Alastair: can i push a little for having those udebs built?)
Those libs could also be moved to the standard path /usr/lib from 
/usr/local/lib
-files contained in /etc (mostly configuration files for gtk and , pango 
, fontconfig), that should override anything else also provided by 
regular udebs


*Fonts should be provided by a separate "d-i_gtk_fonts.tar.gz" (or maybe 
by an unofficial udeb); maybe it's worth also including Hebrew fonts in 
this archive

*gtk.so will be provided by a d-i_gtk_frontend.tar.gz (or, better, by an 
unofficial cdebconf-gtk-udeb) and hand-compiled against GTK with DFB 
backend since automatic building is not possible due to lack of 
libgtk+2.0-directfb0-udeb-dev.


To summarize once again we need to include inside the initrd

*The official udebs listed above
*Files from d-i_gtk_root.tar.gz
*Files from d-i_gtk_fonts.tar.gz (or maybe an equivalent udeb)
*Files from d-i_gtk_frontend.tar.gz (or maybe an equivalent udeb)

I think i'll have to learn a lot of things on building udebs and a lot 
of testing will be needed to make all those pieces work togheter.

ciao
