Hello all I could not find a proper documentation explaining each step explicitly regarding the compilation from source including leptonica and some other image libs.
Therefore I created my own scripts and wanted to share them here. Hopefully others might benefit as well. Starting with libpng, libjpeg and libtiff (looks like libz I had was already the most recent). Otherwise having the exact same issue as: https://stackoverflow.com/questions/33659458/tesseract-image-issue - For libjepg: #!/bin/sh # Download package from: # wget http://www.ijg.org/files/jpegsrc.v9c.tar.gz # Then extract to $base/jpeg/ folder. # This script will take care of the rest. # Package details base=$HOME/image-libs pkg=jpeg vrs=9c # Go to source folder cd $base/$pkg/$pkg-$vrs # Run configure ./configure # Compile and install make make test sudo make install - For libpng: #!/bin/sh # Download package from: # wget https://download.sourceforge.net/libpng/libpng-1.6.35.tar.gz # Then extract to $base/png/ folder. # This script will take care of the rest. # Package details base=$HOME/image-libs pkg=libpng vrs=1.6.35 /home/fertinaz/image-libs/png/libpng-1.6.35 # Go to source folder cd $base/png/$pkg-$vrs # Run configure ./configure # Compile and install make check sudo make install - For libtiff: #!/bin/sh # Download package from: # wget http://download.osgeo.org/libtiff/tiff-4.0.9.tar.gz # Then extract to $base/tiff/ folder. # This script will take care of the rest. # Package details base=$HOME/image-libs pkg=tiff vrs=4.0.9 # Go to source folder cd $base/$pkg/$pkg-$vrs # Run configure ./configure # Compile and install make sudo make install - Assuming that everything went fine, you can move to next step which is compiling leptonica: #!/bin/sh # Get the leptonica source. # I located it in $HOME/leptonica # Package details base=$HOME pkg=leptonica # Go to tesseract repo cd $base/$pkg # Start from scratch each time this script is called rm -rf build && mkdir build && cd build # Compile and install cmake .. -DBUILD_PROG=1 make sudo make install - Now you should be able to start compiling tesseract-ocr: #!/bin/sh # Created clone of the git repo under $base # Then installed to $prf # Package details base=$HOME/Tesseract pkg=tesseract prf=$base/$pkg/install # Go to tesseract repo cd $base/$pkg # Generates configuration script ./autogen.sh # Run configure ./configure --prefix=$prf --enable-debug # Compile and install -- optional check also not sure how necessary is ldconfig when prf is used make make check make install sudo ldconfig - Since this scripts installs tesseract to a specific location, you need to declare the following variable: export TESSDATA_PREFIX=${tesserac_root}/share/tessdata - You can put it to your run scripts or ".bashrc". That's up to you. - One thing that is forgotten is I guess following files needs to be copied to "$install/share/tessdata": $:~/Tesseract$ ls lang-packs/ eng.traineddata eng.user-patterns eng.user-words Hope this helps to others who want to compile from scratch. // Fatih -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
