tesseract @3.00_2+eng Not using leptonica

[jack@…]

TL;DR version: tesseract isn't building with leptonica. Long version:

If install tesseract using:

$ sudo port selfupdate
$ sudo port install tesseract

... I get an install in /opt/local that gives me this on invocation:

Tesseract Open Source OCR Engine with LibTiff

... and fails to handle any PNG I pass it, telling me something like this:

name_to_image_type:Error:Unrecognized image type:fe-1.png
IMAGE::read_header:Error:Can't read this image type:fe-1.png
Read of file fe-1.png failed.

When I look in the configure script, I see that the leptonica check looks like:

 16433  # Check location of leptonica/liblept headers.
 16434  have_lept=no
 16435  for incd in /usr/local/include /usr/include
 16436  do
 16437    for lept in . leptonica liblept
 16438    do
 16439      if test -r "$incd/$lept/allheaders.h" ; then
 16440        CPPFLAGS="$CPPFLAGS -I$incd/$lept"
 16441        have_lept=yes
 16442      fi
 16443    done
 16444  done

... and adding /opt/local/include to line 16435, then re-building, gets me a binary that gives me this on invocation:

Tesseract Open Source OCR Engine with Leptonica

... which happily processes whatever PNG I pass it.

Please remember WikiFormatting.

I believe we solved this in the process of updating tesseract to 3.01. Can you please check?

Replying to ryandesign@…:

I believe we solved this in the process of updating tesseract to 3.01. Can you please check?

I'm not seeing that version in ports:

$ sudo port selfupdate
--->  Updating MacPorts base sources using rsync
MacPorts base version 2.0.3 installed,
MacPorts base version 2.0.3 downloaded.
--->  Updating the ports tree
--->  MacPorts base is already the latest version

$ port list | grep tesser
py26-tesser                    @0.0.1          python/py26-tesser
tesseract                      @3.00           textproc/tesseract

... maybe it hasn't been checked in?

Commits are synced to the rsync server every 30 minutes. So wait 30 minutes from the time of my message, then "sudo port selfupdate", then try again.

Argh, it ate the formatting in my reply, sorry.

[ryandesign@…]

I've fixed your WikiFormatting. Yes, unfortunately between the time we developed the patch to update the port to 3.01, and the time I committed it, a new version of automake 1.11.2 was released which tesseract does not like. As a workaround for now, you could downgrade to automake 1.11.1.

[ryandesign@…]

This ticket was about tesseract not using leptonica. As I said above, I believe that issue is resolved. The new issue of tesseract not building with automake 1.11.2 is tracked in #32913.

[jack@…]

Works a treat with automake 1.11.1.
