--- Begin Message ---Package: ocrodjvu Version: 0.10.2-1 Severity: important After upgrading tesseract to 4.x, ocrodjvu does not work for me at all. The immediate error message is: usage: ocrodjvu [options] FILE ocrodjvu: error: language pack for the selected language (eng) is not available That's when I run ocrodjvu -e tesseract -l eng on some file. Looking closer it seems that ocrodjvu does not find any files anymore. It seems that this is due to tesseract having changed the layout of files (or the error message). Formerly the files were located in /usr/share/tesseract-ocr/tessdata/, but now they moved to /usr/share/tesseract-ocr/4.00/tessdata/. ocrodjvu uses the command "tesseract '' '' -l nonexistent" to find these paths and for an old tesseract the output was: Tesseract Open Source OCR Engine v3.03 with Leptonica Error opening data file /usr/share/tesseract-ocr/tessdata/nonexistent.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory. Failed loading language 'nonexistent' Tesseract couldn't load any languages! Could not initialize tesseract. But for the new tesseract the output is: Error opening data file /usr/share/tesseract-ocr/4.00/nonexistent.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language 'nonexistent' Tesseract couldn't load any languages! Could not initialize tesseract. Note in particular that the error message lacks the tessdata subdirectory. This confuses ocrodjvu such that it doesn't find any languages. One can make symlinks from foo -> tessdata/foo to work around the issue. This could be a tesseract bug, so maybe it needs to be reassigned. Helmut
