--listlangs shows no installed languages

[Nicolas Nickisch]

I compiled and installed tesseract 3.03 manually.

tesseract --listlangs gives me an error message:

error opening data file /usr/local/share/tessdata/eng.traineddata

INdeed, I don't have eng.traineddata in that directory, but deu.traineddata.

Is there something I have to do to install german language files ?

To provided correct information about available languages there is need to initialize tesseract (to get tessdata directory path).

If you do not specified language, tesseract will use default language (= English) for its initialization. Usually English data is installed by default.

Solutions are:

1. Install English language file (I would suggest also osd)
2. Provide existing language as parameter e.g.:
   tesseract --list-langs -l deu
   where deu will be used only for initialization...
