Delete libevdocument1 , libevview1 from that sudo apt-get install line and try again.

Check the latest INSTALL doc for the details. Code has some changes. Pull again and install the latest one.

Reopening as we are not able to process djvu files. Bengali Wikisource is full of such files.

Do you have ddjvu installed?

Run

sudo apt-get install ddjvu

Run ddjvu in command line as

ddjvu filename.djvu filename.pdf

and share the results. On 28 Dec 2015 16:15, "ravidreams" notifications@github.com wrote:

Same error.

[omshivaprakash]

This might help: $ sudo aptitude install djvulibre-bin The following NEW packages will be installed: djvulibre-bin libgraphicsmagick++11{a} libgraphicsmagick3{a} pdf2djvu{a}

Here are the other recommended packages: libdjvulibre21 okular-extra-backends evince libevdocument3 libevview3 libtiff-tools

Shrini,

When I run

ddjvu filename.djvu filename.pdf

djvu file is converted to pdf file. But, it is only an image file and not a pdf file.

file test.pdf

gives following info:

test.pdf: Netpbm PPM "rawbits" image data, size = 1654 x 2338

Example file - https://upload.wikimedia.org/wikipedia/commons/d/de/%E0%A6%86%E0%A6%B0%E0%A7%8B%E0%A6%97%E0%A7%8D%E0%A6%AF-%E0%A6%B0%E0%A6%AC%E0%A7%80%E0%A6%A8%E0%A7%8D%E0%A6%A6%E0%A7%8D%E0%A6%B0%E0%A6%A8%E0%A6%BE%E0%A6%A5_%E0%A6%A0%E0%A6%BE%E0%A6%95%E0%A7%81%E0%A6%B0.djvu

Om, I tried all the steps you suggested and also installed everything related to djvu found at

http://packages.ubuntu.com/search?keywords=djvu&searchon=names&suite=trusty&section=all

No luck yet. Try the example bengali file given above. But, it will give encoding error if you pass the djvu issue :)

We have to find a way to convert djvu files to PDF files in commandline in linux.

I tried as

ddjvu -format=pdf test.djvu test.pdf which gives good pdf file.

source : http://en.proft.me/2014/02/12/how-convert-djvu-pdf-linux/

I tried djvu2pdf from http://0x2a.at/s/projects/djvu2pdf which also works fine.

Can anyone try these two with various djvu files and share the results?

[ravidreams]

ddjvu -format=pdf test.djvu test.pdf gives good pdf conversion.

ravi@ravi-Satellite-L50-B ~/Downloads $ file test.pdf test.pdf: PDF document, version 1.2

But, after running do_OCR.py again stuck at https://github.com/tshrinivasan/OCR4wikisource/issues/10 :(

Actually, just now realized pdf conversion was not successful:
