Gnome 3.16

Classes are finally out for summer and it is time for catch up.  Still, I had time to cause undue stress in my life.  I decided to do what I had promised myself I would not do again, install a new version of Gnome before it was stable in portage.  Anyway, the upgrade to Gnome 3.16 was not without pains along the way, but it is done.

Gnome OCR and Other Stuff

I was looking for an OCR app to use with Gnome/Gentoo and decided to give OCRFeeder a try.  It is available in the an overlay which makes it easier to keep up with for updates.  It is found in the anyc overlay.

layman -a anyc  then  emerge ocrfeeder (have to unmask)

WTF!!! A lot of rebuilds and new packages … that means probable trouble.  Yep, mplayer2 will not compile.  One of the updates was for ffmpeg and that had me worried that I had run into my first libav–ffmpeg blowup because I use ffmpeg rather than the mandated libav.

So, I unmask mplayer2-2.0_p20131009-r1 and still get the error:

libmpdemux/aviheader.c: In function ‘read_avi_header’:
libmpdemux/aviheader.c:600:8: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result [-Wunused-result]
fread(&magic, 6, 1, fp);
^

#error MP_INPUT_BUFFER_PADDING_SIZE is too small!
^
Makefile:536: recipe for target ‘libmpdemux/demuxer.o’ failed

Well, I try emerge @preserve-rebuild without mplayer2 and now I get this for /vlc-2.1.2:

checking for AVCODEC… yes
configure: error: libavcodec versions 56 and later are not supported yet.

Yep, vlc is giving me issues.  Now I am on the slippery slide of getting off the Gentoo path, so I up the stakes, I unmask media-video/vlc-2.1.5-r1 and try again.  You might ask why jump up to 2.15-r1 and I would reply that if I am going to blow things up badly then I might as well go big.

Great, now k3b errors on compile!  Unmask k3b-2.0.3-r1 and emerge without problems.  Okay, so where am I now?  Yep, back to this mplayer2 issue:

libmpdemux/demuxer.c:48:2: error: #error MP_INPUT_BUFFER_PADDING_SIZE is too small!
#error MP_INPUT_BUFFER_PADDING_SIZE is too small!

I don’t feel like going to battle for mplayer because I only use vlc or others, so a quick:

equery d mplayer2

results in:

  * These packages depend on mplayer2:
media-video/smplayer-14.9.0-r1 (media-video/mplayer2[libass,png,X])

So:

emerge –unmerge mplayer2 smplayer 

Now what was I doing?  Yep, OCRFeeder install.  Well, that went okay finally, but OCR engines have to be installed.  I installed gocr, ocrad, cuneiform, and tesseract.  OCRFeeder lets the user select the engine.

Another day in Gentoo world ….

 

Tracker Thrashing at Gnome Boot

Use Gnome?  What is Tracker?  Well, here is the official description:

Tracker is a search engine, search tool and metadata storage system.

It allows you to find the proverbial needle in your computer’s haystack as well as providing a one stop solution to the organisation, storage and categorisation of your data.

Source:  Tracker Wiki

I would add that Tracker kills my system at boot.  Maybe not kill, but brings it to a crawl.  I have thought about disabling it, but sometimes I like the Gnome desktop search.  My fix for the boot issue:

/etc/xdg/autostart
 
littleturd autostart # ls -l tracker*
-rw-r--r-- 1 root root 524 Dec 30 21:33 tracker-extract.desktop
-rw-r--r-- 1 root root 532 Dec 30 21:43 tracker-miner-fs.desktop
-rw-r--r-- 1 root root 597 Dec 30 21:44 tracker-store.desktop

Now change the following in each of the above files:

X-GNOME-Autostart-enabled=false

Of course, resetting things helped too.

/etc/xdg/autostart
tracker-control -r   :Kill all Tracker processes and remove all databases
tracker-control -s   :Starts miners (which indirectly starts tracker-store too)

Last, don’t be dumb like me who mounts his NAS in his home directory, know what directories tracker is set to scan!
