Building and packaging anaconda is not hard once you have all the sources checked out. These two tasks will be described separately, even though they are pretty similar. Building is just compiling the handful of programs and libraries. Packaging is building, followed by putting everything together into an RPM. These will be described using the official Fedora build infrastructure.
The first step is having both the anaconda source and the Fedora package source checked out. Checking out the anaconda source is described in detail on the main page. Checking out the package source is described in detail on the page. For now, let's assume the anaconda source is in src/ and the package source is in pkg/.
Why might you just want to build anaconda instead of building a package? Of course there's the obvious reason that you are working on something in the loader and need to see if your changes still compile. You may also want to build a new loader for testing out in a new initrd. Also, sometimes it's good to do a test build real quick to make sure sources still compile and translations still work before submitting it to the build system.
First you need all the requirements installed. If you are running the same version of Fedora that you want to build anaconda for (say, you're using F8 and want to build the F8 anaconda sources), this is pretty straightforward. The easiest way to do this is to build a SRPM file and then automatically install all the build requirements from that using the yum-builddep tool included in the yum-utils package.
clumens@exeter:~$ cd src/ clumens@exeter:~/src$ make src ... Wrote: /home/clumens/rpm/SRPMS/anaconda-18.104.22.168-1.src.rpm clumens@exeter:~/src$ yum-builddep /home/clumens/rpm/SRPMS/anaconda-22.214.171.124-1.src.rpm
This may take a little while, but will end up pulling in all the programs required to build anaconda. This includes compilers and basic libraries if you don't already have them installed. Of course, you will need make to build the SRPM. It's possible to build an SRPM without the makefile target, but it's so much less convenient.
Then, building anaconda is a simple matter of:
If you aren't running the same version of Fedora that you want to target a build of anaconda for (say, you're running F8 and want to build the Rawhide anaconda sources), it's still possible. You'll first need to install the mock package and install all the build dependencies of the anaconda package in the right mock chroot.
clumens@exeter:~/src$ make src ... Wrote: /home/clumens/rpm/SRPMS/anaconda-126.96.36.199-1.src.rpm clumens@exeter:~/src$ mock -r fedora-8-i386 /home/clumens/rpm/SRPMS/anaconda-188.8.131.52-1.src.rpm ...
The first time you run this, it will take a long while as it downloads and installs all the package build dependencies. The slower your repos, the longer it will take. Afterwards, you will have a mock chroot populated with all the libraries and programs needed to compile anaconda. You can then chroot into it and do a build:
clumens@exeter:~$ sudo su - root@exeter:~# mount -o bind /home/clumens/src /var/lib/mock/fedora-8-i386/root/root root@exeter:~# chroot /var/lib/mock/fedora-8-i386/root/ root:~# make ...
Doing an official build of anaconda for Fedora is not hard either. We have some makefile targets to make things much easier. The first step is to build a tarball from anaconda source. Before doing that, it's good to make sure you've got the latest stuff.
clumens@exeter:~$ cd src/ clumens@exeter:~/src$ git fetch && git rebase origin clumens@exeter:~/src$ make bumpver
This last command updates the anaconda.spec file to increase the version number and write out a %changelog entry. Since this entry is made automatically from the git logs, it's a good idea to check it by hand and make sure there's nothing strange in there. In particular, it's good to get rid of merge commit messages. No one cares about those. Then it's time to make use of that package CVS checkout from earlier.
clumens@exeter:~/src$ make archive clumens@exeter:~/src$ git push clumens@exeter:~/src$ git push --tags clumens@exeter:~/src$ cp anaconda.spec *.bz2 ~/pkg/devel/ clumens@exeter:~/src$ cd ~/pkg/devel/ clumens@exeter:~/pkg/devel$ make upload FILES=*.bz2
Now update the sources file like you are told to and remove the old entry. Then continue like so:
clumens@exeter:~/pkg/devel$ cvs ci clumens@exeter:~/pkg/devel$ make tag clumens@exeter:~/pkg/devel$ make build
Then you just wait for the package to work its way through the build system. If all goes well, there's nothing left to do. However if the build fails, you can check the provided link and view the log files to determine the cause of the problem. Then it's back to the beginning of the whole packaging process to try again.
