I tried running this command on my system and of course got:

Error opening data file /opt/local/share/tessdata/eng.traineddata
Tesseract Open Source OCR Engine v3.01 with Leptonica
Cannot open input file: training-text.tiff

Where can I get this file? The only hit for that filename on Google is this mailing list thread.


I tried using a different tiff I already had, and got this message:

Error opening data file /opt/local/share/tessdata/eng.traineddata
Tesseract Open Source OCR Engine v3.01 with Leptonica
Page 0
Segmentation fault: 11

So I installed the port tesseract-eng to get the English trained data. Then I ran the command again, and it properly OCR'd the file.

Do you have tesseract-eng installed as well? If not, try installing that.
