====== GTK+ Libraries ====== Compilation and installation of GTK+ packages and libraries. ===== About ===== This chapter describes the installation and configuration of GTK libraries on SliTaz used by lots of free software. Note that you can simply compile and create a SliTaz package that you can install on demand with tazpkg. The compilation of GTK applications can take quite some time and you must meet many dependencies. You will find a guide in English: [[http://developer.gnome.org/gtk/2.22/gtk-building.html|gtk-building.html]] on developer.gnome.org. This document sets out the need to compile things in order: Glib, Pango, ATK and GTK+, etc. Before commencing you must verify that the dependencies are properly installed on your host system. Glib, Pango, ATK and GTK+ form a group of packages and are distributed by the team of GTK developers. ==== Environmental variable ($fs) ==== If you do not specify any path to the rootfs directory, export the environmental variable: # export fs=$PWD/rootfs To check: # echo $fs ===== cairo-1.2.6 - 2D graphics library ===== We begin with libcairo (http://www.cairographics.org/) used to compile pango: # cd src # wget http://cairographics.org/releases/cairo-1.2.6.tar.gz # tar xzf cairo-1.2.6.tar.gz # cd cairo-1.2.6 # ./configure --prefix=/usr --mandir=/usr/share/man \ --with-html-dir=/usr/share/doc # make # make DESTDIR=$PWD/_pkg install # strip -v _pkg/usr/lib/*.so* ==== Install in rootfs ==== # cp -av _pkg/usr/lib/*.so* $fs/usr/lib ===== glib-2.12.4 - C routines ===== # cd .. # wget ftp://ftp.gtk.org/pub/glib/2.12/glib-2.12.4.tar.bz2 # tar xjf glib-2.12.4.tar.bz2 # cd glib-2.12.4 # ./configure --prefix=/usr --sysconfdir=/etc \ --mandir=/usr/share/man --with-html-dir=/usr/share/doc # make # make DESTDIR=$PWD/_pkg install # strip -v _pkg/usr/bin/* # strip -v _pkg/usr/lib/*.so* ==== Install in rootfs ==== Option: the utilities glib-genmarshal and gobject-query need the /lib/tls/librt.so.1: # cp -a _pkg/usr/lib/*.so* $fs/usr/lib # cp -a _pkg/usr/share/locale/fr $fs/usr/share/locale The binaries and options: # cp -a _pkg/usr/bin/* $fs/usr/bin ===== pango-1.14.8 - Library for layout and rendering of text ===== # cd .. # wget ftp://ftp.gtk.org/pub/pango/1.14/pango-1.14.8.tar.bz2 # tar xjf pango-1.14.8.tar.bz2 # cd pango-1.14.8 # ./configure --prefix=/usr --sysconfdir=/etc \ --mandir=/usr/share/man --with-html-dir=/usr/share/doc # make # make DESTDIR=$PWD/_pkg install # strip -v _pkg/usr/bin/* # strip -v _pkg/usr/lib/*.so* # strip -v _pkg/usr/lib/pango/1.5.0/modules/* ==== Install in rootfs ==== # cp -a _pkg/usr/bin/* $fs/usr/bin # cp -a _pkg/usr/lib/*.so* $fs/usr/lib # cp -a _pkg/usr/lib/pango $fs/usr/lib # rm -rf $fs/usr/lib/pango/1.5.0/modules/*.la # cp -a _pkg/etc $fs Create /etc/pango.modules via chroot in the rootfs (pango-querymodules uses librt.so.1): # chroot $fs /bin/ash /# pango-querymodules > /etc/pango/pango.modules # exit ===== atk-1.12.4 - Accessibility toolkit ===== # cd .. # wget http://ftp.gnome.org/pub/gnome/sources/atk/1.12/atk-1.12.4.tar.bz2 # tar xjf atk-1.12.4.tar.bz2 # cd atk-1.12.4 # ./configure --prefix=/usr --mandir=/usr/share/man \ --with-html-dir=/usr/share/doc # make # make DESTDIR=$PWD/_pkg install # strip -v _pkg/usr/lib/*.so* ==== Install in rootfs ==== # cp -a _pkg/usr/lib/*.so* $fs/usr/lib # cp -a _pkg/usr/share/locale/fr $fs/usr/share/locale ===== gtk+-2.8.20 - The GIMP Toolkit ===== # cd .. # wget ftp://ftp.gtk.org/pub/gtk/v2.8/gtk+-2.8.20.tar.bz2 # tar xjf gtk+-2.8.20.tar.bz2 # cd gtk+-2.8.20 # ./configure --prefix=/usr --sysconfdir=/etc \ --mandir=/usr/share/man --with-html-dir=/usr/share/doc # make # make DESTDIR=$PWD/_pkg install # strip -v _pkg/usr/bin/* # strip -v _pkg/usr/lib/*.so* # strip -v --strip-unneeded \ _pkg/usr/lib/gtk-2.0/2.4.0/*/* ==== Install in rootfs ==== # cp -a _pkg/usr/lib/*.so* $fs/usr/lib # mkdir $fs/usr/lib/gtk-2.0 # cp -a _pkg/usr/lib/gtk-2.0/2.4.0 $fs/usr/lib/gtk-2.0 # rm -rf $fs/usr/lib/gtk-2.0/2.4.0/*/*.la Locale and themes: # cp -a _pkg/usr/share/locale/fr $fs/usr/share/locale # cp -a _pkg/usr/share/themes $fs/usr/share The applications: # cp _pkg/usr/bin/gtk-query-immodules-2.0 $fs/usr/bin # cp _pkg/usr/bin/gtk-update-icon-cache $fs/usr/bin # cp _pkg/usr/bin/gdk-pixbuf-csource $fs/usr/bin # cp _pkg/usr/bin/gdk-pixbuf-query-loaders $fs/usr/bin ...

You can also compile a small GTK application such as LeafPad and test! The compiliation and installation of GTK+ applications distributed by default with SliTaz are described in the next chapter [[gtk-apps|GTK apps]]. ===== Generate the initramfs and an ISO image ===== To create a new ISO image, you can use 'mktaziso' in [[http://doc.slitaz.org/en:cookbook:slitaztools|SliTaz tools]] . Or you can create a new initramfs image, copy it to /boot in the root of the cdrom (rootcd) and finally generate an ISO image with genisoimage: # cd $fs # find . -print | cpio -o -H newc | gzip -9 > ../rootfs.gz # cd .. # cp rootfs.gz rootcd/boot # genisoimage -R -o slitaz-cooking.iso -b boot/isolinux/isolinux.bin \ -c boot/isolinux/boot.cat -no-emul-boot -boot-load-size 4 \ -V "SliTaz" -boot-info-table rootcd ==== Following chapter ==== After the libraries, the [[gtk-apps|GTK+ applications]].
