Tesseract-ocr on Redhat 5

[Steven Heydendahl]

Hi all,

Novice here.  I had made a request at my company to install tesseract-ocr on our redhat 5 OS.  

They ended up installing the following:

    rpm -Vp "tesseract-2.04-1.el5.rf.x86_64.rpm"

which is apparently an older version of tesseract.  Now, that completed successfully however, every time I try to run tesseract I get an error message.  Even when I just try to do the following:

    tesseract --version

the response is:

    tesseract:Error:Usage:tesseract imagename outputbase [-l lang] [configfile [[+|-]varfile]...]

and if I try to run tesseract on an image:

    tesseract OCRTest.png text l- eng

    read_variables_file:Can't open /usr/share/tesseract/tessdata/configs/engUnable to load unicharset file /usr/share/tesseract/tessdata/eng.unicharset

I do not know if this was a botched install, if we are missing dependencies, or if tesseract is just not compatible with redhat 5.  Any help is greatly appreciated!

Thanks,

Steve

2.04 is too old.

Please ask install 3.05 + language data (at least eng and osd)

Is tesseract 3.05 available for redhat 5?  Can we just rpm it or do we have to add a repository?
