More e5 repositories available (default, devel, extra)

Today more e5 repositories have been made available to the public. Most notably: e5-default, e5-devel and e5-extra. Also the linux-libre-lts kernel in e5-skel has been updated from minor version 27 to 29.

New to E5? You may want to read this and this post first!

An experimental Arch system

While a minimal working E5 system could be pacstrapped before since the time when the skel repository became available, it is possible to install an E5 system now that is actually useful (without having to relay on packages from mainline Arch). Unlike before, pacstrapping base now installs 34 more packages, among them vim and pacman. So you can now at least edit files and do package management! The base system is now also capable of dhcp.

The group base-devel installs everything necessary for starting to build programs yourself or to do some packaging. This group is a bit larger in comparison with mainline Arch: clang was added to it since that is meant to be the default compiler with E5. However the devel repository holds quite a few more packages which are not part of that group – cmake, valgrind or java7-openjdk are some examples (the later is not quite the latest version, though).

The extra repository offers what you would expect as an Arch user: Tools like wget, VCS like git and subversion, and lots of other things (cups, python, etc.). Only all packages of TeX are in their own separate repo (e5-tex), mainly due to its size.

To install it, see the previous post and add the e5-default repository together with the e5-skel one.

These packages allow for an Arch:E5 system which offers pretty endless possibilities for you to mess with. Happy hacking! 😉

(I’d love to hear your feedback, BTW. Don’t hesitate to post it here or to mail me!)

Known problems

There are a few issues that I am aware of but didn’t have the time to look into properly or haven’t found a solution for, yet. If you think you have an idea on what’s going wrong, please get in touch with me! I’m very interested in any help, even if it’s just a small clue. And of course: Please report any other issues you might run into!

Here’s a list of issues I’m currently aware of:

  • There are some packages which do not compile at all with clang. Sometimes they did work with clang 3.3 but stopped working with 3.4 (or vice-versa). In some cases I’ve found patches or was able to apply a little sed magic. But since I’m not a programmer my capabilities in this area are fairly limited.
  • With some packages the checks fail when built with clang. Since this is an experimental distribution I chose to simply ignore any failed tests and just hope that the package will work correctly, anyway. It’s quite likely however that some don’t.
  • There are cases where c++ programs compile with clang++ in general but not if libc++ is chosen as the standard c++ library. However libc++ is under active development and compatibility will surely increase over time.
  • DragonEgg is seems to be broken in version 3.4. When version 3.3 was the current one I used it with packages that didn’t work with clang and most of them were building fine. Currently I’m falling back on pure gcc for those, too (a bit unwillingly, though).
  • Some packages seem to work but are in fact broken. A perfect example of this is libxcb. It compiles fine with clang but makes X11 unable to start up (and rather misleading error messages made me search for a solution in an entirely wrong direction for days!).
  • The ca-certificates package is part of base but it’s not working corrently after the pacstrap for whatever reason. Simply re-installing it once E5 has booted up solves the problem, though. I’m a but puzzled about this one.
  • There’s some issue with docbook. Some packages try to load entries from the web (sourceforge). This fails with E5 for some reason. I’ve built a few custom Arch-like mini distros before (like an i586 Arch) and never had this problem. I’ll have to dig into that somewhen.
  • I REALLY should update elderlinux.org for E5, but I didn’t find the time to do so, yet…

What’s next?

I’ve already got a few more repositories on my drive. These are e5-x11 (which holds anything related to “pure” X), e5-plus (some uncommon stuff like anything that’s just a make dependency for some package), e5-gtk (for the GTK toolkit(s) and all applications that depend on it), e5-fltk (the FLTK toolkit, an FLTK-based desktop environment, FLTK-based applications) and e5-qt (obviously for Qt and Qt-based applications).

There are a few problems remaining with some packages and a lot of important ones missing completely. I’ll have to put some more work into that. I’d also like to provide the PKGBUILD files that I use(d) to build the E5 packages. These should be of some use for people who want to play around with E5 some more. Perhaps I should just put them on github like many other projects do?

And then I’d like to replace some more core system components with alternative ones (like trying to use obase instead of coreutils, dracut instead of mkinitcpio and things like that). In any case there’s a lot of fun waiting!

[Edit: Forgot to mention the ca-certificates issue.]
