Hi thanks for reply,

I have installed this:

/user@nuxeo:~$ tesseract -v *tesseract 3.01*/

And i have installed* /tesseract-ocr-dev/*/ /packages too. I have/* Ubuntu 11.10*/ with /*g++ 4.6.1.*/

I get this error:

Since you are using -fpermissive, this is not an error anymore. Gcc keeps warning you about that issue but ignores it.

And this:

According to your config.log and what you are telling me, it seems that you have two versions of tesseract installed 2.04 and 3.01. Right ? I have tried to compile Olena on a fresh install of Ubuntu 11.10 and everything went fine (with -fpermissive). Tesseract 2.04 was used though, since, AFAIK, this is the only version officially provided by Ubuntu for now. * Did you installed both versions of tesseract in the standard directories (/usr/ but not /usr/local) ? It might be an issue of our configure script which gets confused by the two versions installed. * What does this command print: $ which tesseract * You will definitely get best results with Tesseract 3.01. I advice you to install it manually in a separate location by doing the following: #Download files sudo apt-get install libleptonica-dev cd /tmp wget http://tesseract-ocr.googlecode.com/files/tesseract-3.01.tar.gz http://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.01.eng.tar.gz #Install Tesseract core tar zxvf tesseract-3.01.tar.gz cd tesseract-3.01 ./autogen.sh ./configure --prefix=/usr/local sudo make install #Install English support cd .. tar zxvf http://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.01.eng.tar.gz sudo mv tesseract-ocr/tessdata/* /usr/local/share/tessdata/ Now you have Tesseract 3.01 installed in /usr/local Go back to your olena directory and set the location of Tesseract during configure: cd <olena_dir> ./configure --with-tesseract=/usr/local make Now Olena should use Tesseract 3.01 and compile without any issue. -- Guillaume Lazzara EPITA Research and Development Laboratory (LRDE) 14-16 rue Voltaire F-94276 Le Kremlin-Bicetre France phone +33 1 53 14 59 39 - fax +33 1 53 14 59 22
