            How to link liblept and libtesseract files in linux
            Asked 2020-Nov-19 at 11:41

            I am using .net core c# code to extract text from image using Tesseract. I have added Tesseract 3.3.0 to my project using NuGet package command. This code is working fine on my windows machine. However this fails on Linux machine. After research on internet, I got to know that I need to link liblept and libtesseract files. Hence I am doing below to link the files.

            First error you did is pretending that tesseract library 4.x version is tesseract 3.x (by creating symbolic link). This will never work. 3.x library is outdated not support, so best thing you can do is upgrade your app to 4.x/5.x tesseract.

            Seems it is not loading the native Dlls.

            1. The Tesseract DLLs were built with VS2015 and therefore depend on the Visual C++ 2015 Redistributable Packages. Install it.

            2. Tesseract, Ghostscript, and Leptonica Windows 32- and 64-bit DLLs are embedded in tess4j.jar and lept4j.jar, respectively. So make sure you have them on the class path.

            3. Make sure you have all the dependency libraries on the class path (The Libraries can be found in Your_downloaded_Tess4J_folder\lib )

            4. Make sure you have "tessdata" folder on the class path (The "tessdata" folder can be found in Your_downloaded_Tess4J_folder).

              Please read the Tess4J Tutorial for better understanding.

            This Solution is working for me, tesseract or tess4j is dependable to vs2015 not vs2013 as I did found in some threads. all I did was installing Visual C++ 2015 Redistributable Packages. and it works fine

            Thanks for help

            I am also having the same specification as you.

            Eclipse : 64bit

            JDK 1.8 :64bit

            OS :64bit

            jar Tess4j :3.4.2 version

            Check in your installed programs (Control Panel->Programs->Programs and Features) for

            microsoft visual c++ 2015 redistributable x64 is avalable or not.

            If not then download it from here and install it.

            Then try your app running again. It worked for me
