Recently, when updating the gentoo linux on my amd64 box I got errors when building packages with the doc USE flag. All failing packages were using the gtkdoc tool for generating the documentation. Nowhere in the web was a topic concerning this problem. All these packages failed similar to example for libbonobo below. But many other ebuilds, i.e. glib, gedit etc. were also affected.

After some days of searching I was able to track the issue down to the part of gtk-docfixref that uses vim for highlighting. Perhaps my gtk-doc version (gtk-doc-1.13-r2) is not compatible to my vi version (vim-7.2.303). Even uninstalling vi for testing purposes was not successful since at least this version of gtk-docfixref tries to use vi even if it is not installed.

Line 290 of gtkdoc fixref:

if (“/usr/bin/vim” ne “”) {

Changing this line to

if (“/usr/bin/vim” ne “/usr/bin/vim”) {

for forcing gtk-docfixref to always ignore vi was the (temporary) solution for me. Afterwards I was again able to build all the packages using gtk-doc for documentation.

Since I did not find any information about the problem in the web I am quite unsure if I should open a bug report for it or if it is only a local problem.  So, if you experience the same problem please leave a comment.

I´m running gentoo linux x86_64 on my dell laptop. Today mail-client/mozilla-thunderbird-3.0.3 was aviable in portage and so I upgraded, but there was no lighning for Thunderbird 3 in the portage. Since I need the calendar in thunderbird I searched the web for a solution. After short time I found it in google groups.

On Gentoo just do this:

emerge =mail-client/mozilla-thunderbird-3.0.3 =x11-plugins/enigmail-1.0.1-r1

Download the lightning.xpi from http://mozilla.osuosl.org/pub/mozilla.org/calendar/lightning/releases/1.0b1/contrib/linux-x86_64/ and install it via Tools->Addons.

Now have fun with your new Thundebird.

Best regards xexplorer

Some years ago I played nethack on my old PC. Nethack is a Diablo like RPG that was originally released in 1987. Before playing a game, you have to create a character. You can choose between different character classes: Archeologist, Barbarian, Caveman, Healer, Knight, Monk, Priest, Ranger, Rogue, Samurai, Tourist Valkyrie and Wizard. These classes have different abilities in fighting and using magic. Afterwards you can descent to the dungeon where you have to retrieve the Amulet of Yendor and defeat the bad Moloch. For some more information on gameplay and how to win see the links below the post.

By chance I discovered a maemo package for vultures eye which I installed on my Nokia N810. Vultures eye is a nice graphical frontend for nethack.

Which dragon shall I ride? - Vultureseye on the N810

Then I felt it would be nice to have Vultures Eye also on my PC. With a large screen and real mouse/keyboard input the game is easier to play, than on the small n810s touchscreen. Since the latest available Gentoo ebuild was far out of date and the sources for it are no longer available I wrote a new ebuild based upon the old one. You may download my new ebuild from here: [download#38]

vultureseye on gentoo

To use the ebuild it just copy it to /usr/local/portage/games-roguelike/vultures/. You probably have to create the directory. Then run

ebuild /usr/local/portage/games-roguelike/vultures/vultures-2.2.100.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just emerge vultures and enjoy many YASDs. But beware, one can get quite addicted to this game.

I have searched for a 3D game on Linux and found this nice flight simulation. In Gentoos portage tree there is only an old version avaiable, so I wrote an ebuild for the new version. It compiles fine on my computer wth 64bit Gentoo – Linux.

The Power of my graphics board (nVidia Corporation Quadro FX 360M) seems to be enough for this simulation. The control is not easy, but with some time, you can fly around, like in a real aircraft.

What is FlightGear?
The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. Source code for the entire project is available and licensed under the GNU General Public License.

HowTo install on Gentoo:

Download [download#37] file which include the ebuilds

cd /usr/locale/portage
tar -xzpvf ~/flightgear-2.0.0.tar.gz

Then you have to unmask the ebuilds in /etc/portage/package.keywords :
=games-simulation/flightgear-2.0.0 **
=dev-games/simgear-2.0.0 **
=dev-libs/boost-1.37.0-r1 **
=dev-util/boost-build-1.37.0 **
=media-libs/freeglut-2.6.0  **

now you can ’emerge =games-simulation/flightgear-2.0.0′

Have fun

Xexplorer

UPDATE 04.03.2010:

Now it´s in portage, with two different lines. First of all I found out that freeglut 2.6 is needed for flightgear, so I put it in the ebuild. And the second is a patch witch is needed if you don´t use freeglut 2.6. So I think my choice is the better way.

On a gentoo system you may get the error

QA Notice: Package has poor programming practices which may compile but will almost certainly crash on 64bit architectures

during emerge. This is usually a wanted behaviour since one does not want to have broken packages installed, but sometimes you may want to decide yourself or you need the program and can live with crashes that may occur under certain circumstances. As far as I know portage does not give us an easy method to override this.

You may change this behaviour by changing line 477 in /usr/lib/portage/bin/misc-functions.sh to i.e.

if [[ ${abort} == “disabled” ]] ; then

After emerging the brocken package you usually want to change the line back to

if [[ ${abort} == “yes” ]] ; then

to prevent having broken packages on your system without knowing about it.

Hoping this information is of some help.

One year ago I provided a gentoo ebuild for mplayer which included support for quad-buffered stereo, enabling mplayer to display stereoscopic movies like the great movie Avatar3D I watched in cinema today. To learn more about the movie look here and here. Sadly the patch I referenced there does not apply over newer mplayer versions. So I had to modify the original patch from Stuart Levy to work again with newer mplayer versions. You may download the updated patch from here:

[download#35]

New version available!

The patch should work at least with nvidia quadro boards, probably with some others. It can be used with CRT and generic shutter glasses or HMDs like the Vusix VR920. Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I also modified the mplayer ebuild from portage to include the patch. The modified ebuild is available here:

[download#36]

New version available!

The older ebuild is still available on mygnu.de.

To use the ebuild it just copy it to /usr/local/portage/media-video/mplayer and copy the the patch to the “/usr/local/portage/media-video/mplayer/files” directory.  You probably have to create these directories. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc4_p20091026-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy the experience in the 3rd dimension again.

With linux kernel 2.6.32 module parameters for kvm-intel changed so if you cannot load the module anymore and you get errors in dmesg like

kvm_intel: Unknown parameter `enable_vpid’
kvm_intel: Unknown parameter `enable_ept’
kvm_intel: Unknown parameter `flexpriority_enabled’

you should update your module config. For gentoo users this means to edit the file

/etc/modules.d/kvm_intel

and to remove the obsolete parameters. Afterwards run

update-modules -f

Now you should be able to load the module and do kvm vitualization again.

For me this problem occured when trying the new zen-sources-2.6.32-zen1 (also in zen2). Sadly this kernel is affected by the bug which causes higher power consumption (at least on my Precision M65) when not running a suspend to ram cycle before. This also occurs with vanilla sources. For more information on this topic see bugzilla.kernel.org.
