I'm trying to use Aletheia and tesseract-orc with some images in mac. But I faced many problems:

  1. I can't make Aletheia work with wine, it just doesn't open

  2. I followed the instruction of the question Stackoverflow question but I've got this result regarding the use of Tesseract OCR to Page (TPT) and Page Viewer (PVT):

    $ java -XstartOnFirstThread -jar JPageViewer.jar "$dl/Downloads/paper-3-tool.xml" "$dl/Downloads/paper-3.tif"

  • Seems you are using an outdated version of a lib which causes incompatibilities. – Fildor Dec 08 '15 at 19:21
  • Ok, How can I fix it?? I've updated to the latest Java version, and I've also tried with the jar-launcher of my mac, but it retrieves error. I don't know why I can't open .jar files – soluna Dec 08 '15 at 19:48
