[[Image(/elive/images/tux-debian.png)]] == What is == CDBS is the most easy tool in debian to create debian packages, you will need just 2-3 lines of code so that you will create your own debian packages On this howto I will explain the basic steps to do this, but cdbs is a lot more powerful (hooks in pre-config, post-config, pre-compile, post-compile, etc etc), so for more information just follow the documented PDF as, of course, '''/usr/share/doc/cdbs''' == Dependencies == You basically only need the package '''cdbs''', but is recommended also to install these packages: '''dpkg-dev devscripts''' == Hands on ! == On this example we will create a debian package for '''enna''' under a Elive system Download the sources of enna and create the directory ''debian'' (if is already created and has files mean that is already ready for create debian packages, or supposed to... in any case, if is created, just remove it in order to follow this howto). On it, you need to have 2 files, '''control''' and '''rules''' In the '''debian/control''' file has the description of the package, we can fill up with something like: {{{ Source: enna Section: enlightenment Priority: optional Maintainer: yourname Build-Depends: cdbs, autotools-dev, gnulib, debhelper, libplayer, gettext, libsqlite3-dev, lubcurl4-gnutls-dev, libdbus-1-dev, libx11-dev, libxml2-dev, libfreetype6-dev, libjpeg62-dev Package: enna Architecture: any Depends: efl-all, libcddb2, libexif12, libhal-storage1, libhal1, libplayer, libsqlite3-0, libxml2, lightmediascanner, libxrandr2 Description: enna media player This is the enna media player using EFL }}} Note: These dependencies are a bit tricky here, the efl-all package will contain all the libs of EFL, but there's no a efl-all-dev package that will contain the rest of dependencies like libdbus, libcurl, libfreetype, etc, so just play with your own dependencies for your packages The first block is for the source packages (so that you can ''apt-get source enna'' in the future in order to recompile it), it also contains the information about which dependencies you need to have in order to compile it. The second block is for the binary end package. In the '''debian/rules''' file, you need to fill up with something like: {{{ #!/usr/bin/make -f DEB_AUTO_UPDATE_DEBIAN_CONTROL := yes include /usr/share/cdbs/1/rules/debhelper.mk include /usr/share/cdbs/1/class/autotools.mk DEB_CONFIGURE_EXTRA_FLAGS := --disable-browser-netstreams --enable-libcddb --disable-browser-lms }}} The first line means that the control file will be updated automatically (it was really needed to explain this point ? anyways...), the next lines means which pieces of cdbs we want to have, like a dependency, if we don't include them, we don't have its support, like, debhelper contains all the needed things for build the package, autotools contains the needed things for compile a simple C/C++ program that has its makefiles structure and such... so, the basic needed ones. The final line includes the option of compilation. '''Note''': You need to made the rules file executable, so run: '''chmod +x debian/rules''' You are almost ready, altough these are the only ''real'' needed files, you need a few last tricks... but they are almost automatic: You need the '''changelog''' file, since we are lazy, we use the tool '''debchange''' to create/update it, see that there's a warning saying that there's no any changelog found and so on we need to use the option '''---create''' for create a new one, so, from the directory of the source code (out of the ''debian'' dir), run: '''debchange --create''' '''WARNING''': It is very important that the changelog will have the CORRECT information or you can have problems by compiling the package, for example your PACKAGENAME needs to NOT be uppercase, etc, you can see examples in ''ls /usr/share/doc/*/changelog.Debian.gz'' Your ''debian'' directory is ready, you can add a lot more of options and tricks for your package but for that, just follow the official documentation at /usr/share/doc/cdbs, im not going to write all the features because im lazy too :) == Time to build the package ! == Since we are a user and no root, some commands needs to be prepend with the command '''fakeroot''': Before to compile you need to see if you have all the dependencies for the compilation, for that, just run the command '''dpkg-checkbuilddeps''' It is very possible that you will need to add more dependencies, see if the build give you a compilation error and install the remaining needed dependencies, this step is a bit a pain but it is extremely important to add all the needed dependencies to the '''control.in'' file, if not, when you will ''apt-get source enna'' to compile it yourself, it will not compile. So, the steps are: * Every time a new dependency is needed/found, add it to the control.in file * Install the dependency * Run the combo command: ''fakeroot debian/rules clean ; dpkg-checkbuilddeps && fakeroot dpkg-buildpackage -b'' When you have finally builded the package, is time to build a real one (with source packages and such): run the command '''fakeroot dpkg-buildpackage''' You have it ! == Final points == '''Warning''': If you see errors like ''dpkg-shlibdeps: failure: no dependency information found for /usr/lib...'', this means that the equilvalent lib was not builded using a debian packager system (so, manually compiled), in other words, you should package ''in the debian way'' this package too. So '''it is possible that this example will not work''' (the EFL libs in Elive are not packaged with debian packaging tools, but with a own Elive packager tool) You are free to edit this document in order to fix any thing, making it better, or to add a few nice tricks to know, for that just fill up a collaborator thingy at http://www.elivecd.org/Help/Collaborate You can see some nice and small examples of CDBS in the EFL svn, for example in evas, it use it for build the packages (at least to the date of today) == Interesting Links and more Info == http://debathena.mit.edu/packaging/ file:///usr/share/debhelper/dh_make/
