[request] Linux: leave the creation of the tessdata folder to the user

[Luciana Moreira Sá de Souza]

The functionality to find text on the screen does not work properly. The following error appears:

[debug] ResourceLoaderBasic: loadLib: Is already loaded: VisionProxy
[error] TextRecognizer: init: tessdata folder not found at /usr/local/share/
[error] Region.find(text): text search is now switched off
[error] script [ test1 ] stopped with error in line 6
[error] FindFailed ( Text search currently switched off )

I have seen the bug 1214589, and followed the steps there. I deleted the folder libs, and I do have a subfolder tessdata now. Unfortunately, this does not seem to be enough. The error still occurs.

RaiMan, I did some debuging and found out the source of the problem. In the class org.sikuli.basics.ResourceLoader line 342, you have the following:

if (Settings.OcrDataPath == null) {
      if (Settings.isWindows() || Settings.isMac()) {
        log(lvl, "Using this as OCR directory (tessdata) too");
        Settings.OcrDataPath = libPath;
      } else {
        Settings.OcrDataPath = "/usr/local/share";
      }
    }

I am not sure why on linux we end up on a location different from libPath. Is this a bug or a feature? :)

Are you on Linux?

If yes: absolutely right.

On Linux systems option 5 should not be presented, since it is your own job, to completely install Tesseract (including the tessdata folder, that then usually is at /usr/local/share, if not, you have to change that).

Thanks for pointing out.

[RaiMan (raimund-hocke)]

I will change the behavior for Linux for setup and runtime

Thank you RaiMan!

Yes I am on linux, I use Opensuse.

Is there any chance of defining the path to the tessaract in the SikuliX-IDE? Either via a system property or on the preferences dialog?

For now I can put a symlink, but this is not ideal. Although I see this as a low priority.

--- Is there any chance of defining the path to the tessaract in the SikuliX-IDE?

... you already saw it ;-)
Settings.OcrDataPath = <tell Sikuli your path to the tessdata folder>;

at the very beginning of a script should do it.

BTW: What are the standard places on OpenSuse for the OpenCV and Tesseract stuff?

[Luciana Moreira Sá de Souza (lso)]

Hey RaiMan,

Unfortunately, tesseract is not available in the default opensuse repository. I had to take it from a third party location to get it installed. See: http://software.opensuse.org/package/tesseract (click on "Show unstable packages"). So I am not sure how much we can count on the install location provided by these packages.

In any case, with this unstable package, it got installed on my machine under: /usr/share/tessdata

Regards

[RaiMan (raimund-hocke)]

thanks.

this is the second most location for such stuff besides /usr/local/Share
