Gentoo Weekly Newsletter: 11 December 2006


1.  Gentoo News

EFIKA boards shipped

Christmas came a little early this year for the Gentoo/PPC team and others. A number of developers received the EFIKA, an evaluation board from Genesi built around the MPC5200B PowerPC SoC (System on Chip) running at 400MHz. Also included on the board is 128MB of DDR memory, 10/100 ethernet, 2 USB 1.1 ports, 1 PCI/AGP slot, and sound with optical out.

The Gentoo/PPC team, along with Release Engineering, are working on both detailed instructions for installing Gentoo on the EFIKA, as well as CD media capable of booting the EFIKA from USB. Gentoo would like to thank Genesi for its continued support and Freescale for providing the funding to make this program possible.

For more information on the EFIKA, or to buy one yourself, visit Genesi's EFIKA page.

2.  Heard in the community

D-Bus 1.0.1 has been ~amd64'd

D-Bus, the inter-process communications program, has reached its 1.0 milestone and the resultant 1.0.2 ebuild is in testing. That is the good news. The bad news is that the ABI (application binary interface) was radically shifted from the prior 0.6x releases now stable in portage. Though the title mentions only amd64, it is in testing on multiple architectures.

Emopig issued a warning to his fellow users that when he followed the ebuild's instruction to run revdep-rebuild the resulting list of packages to be re-merged was non-trivial (54 packages for him). Others seconded that, particularly Gnome users. The damage on the KDE side seemed confined to the kde-kioslaves package.

6thpink suggested that users install the binding packages dbus-glib, dbus-python and dbus-qt3-old since the base dbus package no longer had USE flags for python, qt3 or the like. This seemed to help at least one user.

Goodbye, Gentoo

Forums user beazizo has returned after an 18 month absence and said "I must say, it [gentoo] is MUCH better than it was back then. It took me less than a day to get a system up to a point where I had all the apps installed that I was running in Ubuntu (and running much faster). I felt comfortable enough to blow away my Ubuntu install. Good work Gentoo team!"

Welcome back to Gentoo, beazizo.


gnome-screensaver requires emacs?

Chris Bare was trying to install gnome-screensaver, with the following result:

Code Listing 2.1: Trying to emerge gnome-screensaver

# emerge emerge -pv --tree gnome-screensaver

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
 [ebuild  N    ] gnome-extra/gnome-screensaver-2.14.2  USE="pam xinerama -debug
 -doc" 1,872 kB 
 [ebuild  N    ] app-xemacs/emerge-1.09  59 kB 
 [ebuild  N    ]  app-editors/xemacs-21.4.17  USE="X berkdb gpm jpeg png tiff
 -Xaw3d -athena -canna -dnd -freewnn -ldap -motif -mule -nas -neXt -postgres
 -xface" 10,377 kB

He wanted to know why gnome-screensaver seemed, against all logic, to depend on xemacs.

Etaoin Shrdlu spotted the real problem. (Did you?) Chris had typed emerge emerge and portage thought he wanted to emerge the app-xemacs/emerge package and its dependencies.

This serves as a useful warning, since we all make such a mistakes sometimes.


CFLAGS for Intel Core 2 CPUs

The Core 2 Duo is the flagship chip of Intel's CPU line and the "it" processor of the moment. Any right-thinking Gentoo-er has only one question: "What CFLAGS should I use for that bad boy?"

Michael Weyershäuser provided a pointer to a dirtyepic blog post that answered that question based on information from Intel itself. For GCC 4.1, Core Solo/Duo uses -march=prescott while the Core 2 Duo/Solo gets -march=nocona. For GCC 4.2, the -march is the same, but a -mtune=generic flag is added.

3.  Gentoo International

Belgium: DonnaroomLAN, Arendonk

4.  Gentoo in the press (7 December 2006)

Several developers were contacted from several distributions by the article's author, Mayank Sharma, about their distribution's security practices. Mayank spoke with developers from Red Hat, Novell, CentOS, Debian, and, of course, Gentoo. He explains the different methodologies used by the distributions, as well as points out some differences between the community and commercial distributions.
