      Hi,

      As @mchinand already suggested, fix your paths.

      Since they have spaces in them you have to quote them properly.

      Also, having a path ending with a ) is unusual, are you sure it's written like that ?

          @OlegD
          Assuming the correct path is C:\Program Files(x86)\Tesseract-OCR, everywhere you use it you need to copy/paste

          "C:\Program Files(x86)\Tesseract-OCR"
          

          My guess is you need

          INCLUDEPATH += "C:\Program Files(x86)\Tesseract-OCR"
          LIBS += -L"C:\Program Files(x86)\Tesseract-OCR"

            Another way to avoid that: install Tesseract in a folder without spaces and special characters.

              @OlegD said in Qt and Tesseract Linkage:

              tesseract/baseapi.h

              You should find where this file is actually located. It could be that your includepath should be INCLUDEPATH += "C:\Program Files(x86)\Tesseract-OCR\include"

                  Are you getting the same error? What is the full path to this header file on your system?

                    Wouldn't you want to say/confirm what these errors are??

                    If it's failing on #include <tesseract/baseapi.h>, where exactly is that file? Is it at C:\Tesseract-OCR\include\tesseract\baseapi.h?

                        Is there any chance I've installed wrong tesseract version?

                        That's for you to sort out. But there are no .h files, and no include sub-directory.

                            this is incorrect

                            those need to be inline or concatenated via \ to escape the (invisible) newline character

                                Please advise how can I install it properly for QT environment

                                Using Tesseract

                                !!! IMPORTANT !!! To use Tesseract in your application (to include tess or to link it into your app) see this very simple example.
                                Build the latest library (using Software Network client)

                                Download the latest SW (Software Network https://software-network.org/) client from https://software-network.org/client/.
                                Run sw setup (may require administrator access)
                                Run sw build org.sw.demo.google.tesseract.tesseract-master.
                                

                                For visual studio project using tesseract

                                Setup Vcpkg the Visual C++ Package Manager.
                                Run vcpkg install tesseract:x64-windows for 64-bit. Use –head for the master branch.
                                

                                Static linking

                                To build a self-contained tesseract.exe executable (without any DLLs or runtime dependencies), use Vcpkg as above with the following command:

                                vcpkg install tesseract:x64-windows-static for 64-bit
                                vcpkg install tesseract:x86-windows-static for 32-bit
                                

                                Use –head for the main branch. It may still require one DLL for the OpenMP runtime, vcomp140.dll (which you can find in the Visual C++ Redistributable 2015).
                                Build training tools

                                Today it is possible to build a full set of tess training tools on Windows with Visual Studio. You need to have the latest VS compiler (VS2019/2022 or light VS 2019/2022 build tools distro installed.

                                To do this:

                                Download the latest SW (Software Network https://software-network.org/client/) client from https://software-network.org/client/.
                                Checkout tesseract sources git clone https://github.com/tesseract-ocr/tesseract tesseract && cd tesseract.
                                Run sw build.
                                Binaries will be available under .sw\out\some hash dir...
                                

                                Develop Tesseract

                                For development purposes of Tesseract itself do the next steps:

                                Download and install Git, CMake and put them in PATH.
                                Download the latest SW (Software Network https://software-network.org/) client from https://software-network.org/client/. SW is a source package distribution system.
                                Add SW client to PATH.
                                Run sw setup (may require administrator access)
                                If you have a release archive, unpack it to tesseract dir.
                                

                                If you’re using main branch run

                                git clone https://github.com/tesseract-ocr/tesseract tesseract

                                Run
                                
                                 cd tesseract
                                 mkdir build && cd build
                                 cmake ..
                                
                                Build a solution (tesseract.sln) in your Visual Studio version. If you want to build and install from command line (e.g. Release build) you can use this command:
                                
                                cmake --build . --config Release --target install
                                
                                If you want to install to other directory that C:\Program Files (you will need admin right for this), you need to specify install path during configuration:
                                
                                cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_INSTALL_PREFIX=inst
                                

                                For development purposes of training tools after cloning a repo from previous paragraph, run

                                sw build

                                You’ll see a solution link appeared in the root directory of Tesseract.
                                Building for x64 platform
                                sw

                                If you’re building with sw+cmake, run cmake as follows:

                                mkdir win64 && cd win64
                                cmake .. -G "Visual Studio 14 2015 Win64"

                                If you’re building with sw run sw generate, it will create a solution link for you (not yet implemented!).

                                  Run sw build org.sw.demo.google.tesseract.tesseract-master.
                                  

                                  For visual studio project using tesseract

                                  Setup Vcpkg the Visual C++ Package Manager.
                                  Run vcpkg install tesseract:x64-windows for 64-bit. Use –head for the master branch.
                                  

                                  Static linking

                                  To build a self-contained tesseract.exe executable (without any DLLs or runtime dependencies), use Vcpkg as above with the following command:

                                  vcpkg install tesseract:x64-windows-static for 64-bit
                                  vcpkg install tesseract:x86-windows-static for 32-bit
                                  

                                  Use –head for the main branch. It may still require one DLL for the OpenMP runtime, vcomp140.dll (which you can find in the Visual C++ Redistributable 2015).
                                  Build training tools

                                  Today it is possible to build a full set of tess training tools on Windows with Visual Studio. You need to have the latest VS compiler (VS2019/2022 or light VS 2019/2022 build tools distro installed.

                                  To do this:

                                  Download the latest SW (Software Network https://software-network.org/client/) client from https://software-network.org/client/.
                                  Checkout tesseract sources git clone https://github.com/tesseract-ocr/tesseract tesseract && cd tesseract.
                                  Run sw build.
                                  Binaries will be available under .sw\out\some hash dir...
                                  

                                  Develop Tesseract

                                  For development purposes of Tesseract itself do the next steps:

                                  Download and install Git, CMake and put them in PATH.
                                  Download the latest SW (Software Network https://software-network.org/) client from https://software-network.org/client/. SW is a source package distribution system.
                                  Add SW client to PATH.
                                  Run sw setup (may require administrator access)
                                  If you have a release archive, unpack it to tesseract dir.
                                  

                                  If you’re using main branch run

                                  git clone https://github.com/tesseract-ocr/tesseract tesseract

                                  Run
                                  
                                   cd tesseract
                                   mkdir build && cd build
                                   cmake ..
                                  
                                  Build a solution (tesseract.sln) in your Visual Studio version. If you want to build and install from command line (e.g. Release build) you can use this command:
                                  
                                  cmake --build . --config Release --target install
                                  
                                  If you want to install to other directory that C:\Program Files (you will need admin right for this), you need to specify install path during configuration:
                                  
                                  cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_INSTALL_PREFIX=inst
                                  

                                  For development purposes of training tools after cloning a repo from previous paragraph, run

                                  sw build

                                  You’ll see a solution link appeared in the root directory of Tesseract.
                                  Building for x64 platform
                                  sw

                                  If you’re building with sw+cmake, run cmake as follows:

                                  mkdir win64 && cd win64
                                  cmake .. -G "Visual Studio 14 2015 Win64"

                                  If you’re building with sw run sw generate, it will create a solution link for you (not yet implemented!).

                                  All you have done is pasted the whole of the instructions. They are for you to read and act on. Only you know what you did/did not do.

                                  Well, I dont know how to make it work with QT.
                                  I've just installed package, realized that there is no instruction for QT and posted to QT forum.
                                  Please advise how can I install it properly for QT environment

                                  I do not see anything related to Qt, or for Qt instructions.
                                  Your code has #include <tesseract/baseapi.h>.
                                  I pointed out that from what you show there are no .h files anywhere (that I can see).
                                  I suggested you need to see if that file is anywhere, or sort out whatever you need to do to get it available. Assuming you need that line.
                                  I don't use "tesseract", and I don't suppose anybody else here does either.

                                    It looks like what you downloaded was just the pre-built binary and associated files to use the tesseract application and not to develop your own. You will have to build the library yourself; just follow the directions that you posted above closely step by step.

                                      So it was just a sample application? And they do not provide the .h files with it?

                                      Does he really need to build it? IF it comes with pre-compiled external DLLs of whatever to make the (sample?) app work, can't he use those plus .libs & .hs for his own code without having to build the .dlls?

                                        It might be possible but probably easier to just build it. I'm not seeing a .lib only a 'tesseract-5.dll'. I would characterize it as an application that non-developers use and not just a sample application (like you though, I've never used it).

                                          Guys, so if I do want to install close to instruction, how can I proceed with this lines?

                                          For visual studio project using tesseract

                                          Setup Vcpkg the Visual C++ Package Manager.
                                          Run vcpkg install tesseract:x64-windows for 64-bit. Use –head for the master branch.
                                          Static linking

                                          To build a self-contained tesseract.exe executable (without any DLLs or runtime dependencies), use Vcpkg as above with the following command:

                                          vcpkg install tesseract:x64-windows-static for 64-bit
                                          vcpkg install tesseract:x86-windows-static for 32-bit
