Tesseract on Red Hat

[Phil R]

Is anyone running Tesseract on Red Hat?  I'm looking through the docs at  http://code.google.com/p/tesseract-ocr/  and it says they're testing on ubuntu and generically say that it should work on all recent linux versions.

I started going through the install process and I'm getting some unavailable packages, specifically libpng12-dev and libjpeg62-dev.

Hi,

 

I think Red Hat will be fine if you leave out the numbers, i.e.:

 

sudo yum install libpng-devel libjpeg-devel

Great, that worked. I'm getting another problem now. I'm following
the instructions here, in conjunction with the readme on the tesseract
site:

http://paramountideas.com/tesseract-ocr-30-and-leptonica-installation-centos-55-and-opensuse-113

http://code.google.com/p/tesseract-ocr/wiki/ReadMe

sudo yum install libjpeg-devel libpng-devel libtiff-devel zlib-devel
(some of these were already installed
sudo yum install gcc gcc-c++ make (these were already installed for us)

download leptonica
./configure
make
sudo make install

download tesseract-x.xx.tar.gz (unpack)
download tesseract-x.xx.<lang>.tar.gz (unpack files into tessdata)
download <lang>.traineddata.gz (unzip into tessdata)
./autogen.sh
mkdir -p m4
./configure

And here's where we have another problem. When running make, I get
the following:

In file included from params.h:26,
from tprintf.h:23,
from ambigs.h:25,
from ambigs.cpp:24:
strngs.h:1: error: stray '\357' in program

Any idea on this?

Did autogen spit out any errors? Do you have automake installed?

It sounds like the problem reported here:

Great, that seems to have worked, thanks!

[Phil Redmon]

Yep, we have automake, autogen looked like it ran fine:

Running aclocal
Running libtoolize
Putting files in AC_CONFIG_AUX_DIR, `config'.
Running autoheader
Running automake --add-missing --copy
Running autoconf

All done.
To build the software now, do something like:

$ ./configure [--with-debug] [...other options]
$ make

Hi everyone,

Phil, could you finally run tesseract on RedHat? I'm getting some error, could you please specify the versions and how you installed tesseract?

Thank you in advance.
