Ubuntu 12: sikuli-ide crashes with Tesseract 3.0 --- language files missing ???

--- Tesseract couldn't load any languages!
Seems, that Tesseract is not installed correctly on your system

Googling for "Tesseract couldn't load any languages!"
I find a couple of bugs filed. One in debian and one in ubuntu apart from
this one.

Most likely this is not a problem with my system, but a more general
problem with either the packaging of tesseract or with sikuli-ide.

Thanks
Krishna

When using Tesseract 3.0, you have to install the language support files separately
(http://code.google.com/p/tesseract-ocr/wiki/ReadMe)

Might cause the problem in your case.

If Tesseract 3.0 does not work, try to install the prior version 2.04 instead (which is expected by the current version of Sikuli).

I do not know, wether Tesseract 3.0 should be compatible towards Sikuli out of the box.

The upstream debian bug for this problem is

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=667513

Fixed in upstream (at debian), please pull it.

http://packages.debian.org/source/sid/sikuli

When will this fix make it to Precise Pangolin? Will it?

The workaround is to just install the addidional dependencies by hand

sudo apt-get install tesseract-ocr-eng
sudo apt-get install libswing-layout-java

You must also do

mkdir -p /tmp/sikuli
ln -s /usr/share/tesseract-ocr/tessdata/ /tmp/sikuli

(probably every time you start sikuli-ide) as sikuli-ide completely ignores the TESSDATA_PREFIX environment variable that could tell it where to look for its data.

Adding a note to this - in my /tmp dir, a sikuli directory already exists, thus I could not create the link there.
First I did a:
sudo rm -r /tmp/sikuli
followed by Florian's suggestions above (prefaced with sudo):
sudo mkdir -p /tmp/sikuli
sudu ln -s /usr/share/tesseract-ocr/tessdata/ /tmp/sikuli

After this, I do not have the crash associated with libtesseract.so.3

Very happy that sikuli is working now on my Ubuntu 12.04.
In summary, after doing the:
sudo apt-get install sikuli-ide
to get sikuli installed, you must also do (again, Florian points this out earlier):
sudo apt-get install tesseract-ocr-eng
sudo apt-get install libswing-layout-java
and wrap up with what I stated at the beginning of this:
if there is a /tmp/sikuli directory, do: sudo rm -r /tmp/sikuli
and wrap up with:
sudo mkdir -p /tmp/sikuli
sudu ln -s /usr/share/tesseract-ocr/tessdata/ /tmp/sikuli

That's how I got sikuli to run as expected on Ubuntu 12.04.

I modified the procedure in the revised description (and comment #9) and it worked for me. Besides ensuring that I had all the packages mentioned, I also did the /tmp/sikuli steps, but not as sudo, since that seems odd.
Thanks for the workaround. I'm also curious what the changes are in Debian, and how the "in progress" work differs from that.

-- fixed in Debian world
... simply means, that there are packages for Sikuli X available, that simply run out of the box

-- in progress
... is only a marker for me, that I want to visit this packaging stuff again in the next time when the new version is running on my Ubuntu 12
