To run the application without Docker/Podman, you will need to manually install all dependencies and build the necessary components. Note that some dependencies might not be available in the standard repositories of all Linux distributions, and may require additional steps to install. The following guide assumes you have a basic understanding of using a command line interface in your operating system. It should work on most Linux distributions and MacOS. For Windows, you might need to use Windows Subsystem for Linux (WSL) for certain steps. The amount of dependencies is to actually reduce overall size, ie installing LibreOffice sub components rather than full LibreOffice package. You could theoretically use a Distrobox/Toolbox, if your Distribution has old or not all Packages. But you might just as well use the Docker Container then. ### Step 1: Prerequisites Install the following software, if not already installed: - Java 17 or later - Gradle 7.0 or later (included within repo so not needed on server) - Git - Python 3.8 (with pip) - Make - GCC/G++ - Automake - Autoconf - libtool - pkg-config - zlib1g-dev - libleptonica-dev For Debian-based systems, you can use the following command: ```bash sudo apt-get update sudo apt-get install -y git automake autoconf libtool libleptonica-dev pkg-config zlib1g-dev make g++ openjdk-17-jdk python3 python3-pip ``` For Fedora-based systems use this command: ```bash sudo dnf install -y git automake autoconf libtool leptonica-devel pkg-config zlib-devel make gcc-c++ java-17-openjdk python3 python3-pip ``` ### Step 2: Clone and Build jbig2enc (Only required for certain OCR functionality) ```bash mkdir ~/.git cd ~/.git &&\ git clone https://github.com/agl/jbig2enc.git &&\ cd jbig2enc &&\ ./autogen.sh &&\ ./configure &&\ make &&\ sudo make install ``` ### Step 3: Install Additional Software Next we need to install LibreOffice for conversions, ocrmypdf for OCR, and opencv for pattern recognition functionality. Install the following software: - libreoffice-core - libreoffice-common - libreoffice-writer - libreoffice-calc - libreoffice-impress - python3-uno - unoconv - pngquant - unpaper - ocrmypdf - opencv-python-headless For Debian-based systems, you can use the following command: ```bash sudo apt-get install -y libreoffice-writer libreoffice-calc libreoffice-impress unpaper ocrmypdf pip3 install uno opencv-python-headless unoconv pngquant WeasyPrint --break-system-packages ``` For Fedora: ```bash sudo dnf install -y libreoffice-writer libreoffice-calc libreoffice-impress unpaper ocrmypdf pip3 install uno opencv-python-headless unoconv pngquant WeasyPrint ``` ### Step 4: Clone and Build Stirling-PDF ```bash cd ~/.git &&\ git clone https://github.com/Stirling-Tools/Stirling-PDF.git &&\ cd Stirling-PDF &&\ chmod +x ./gradlew &&\ ./gradlew build ``` ### Step 5: Move jar to desired location After the build process, a `.jar` file will be generated in the `build/libs` directory. You can move this file to a desired location, for example, `/opt/Stirling-PDF/`. You must also move the Script folder within the Stirling-PDF repo that you have downloaded to this directory. This folder is required for the python scripts using OpenCV ```bash sudo mkdir /opt/Stirling-PDF &&\ sudo mv ./build/libs/Stirling-PDF-*.jar /opt/Stirling-PDF/ &&\ sudo mv scripts /opt/Stirling-PDF/ &&\ echo "Scripts installed." ``` ### Step 6: Other files #### OCR If you plan to use the OCR (Optical Character Recognition) functionality, you might need to install language packs for Tesseract if running non-english scanning. ##### Installing Language Packs Easiest is to use the langpacks provided by your repositories. Skip the other steps Manual: 1. Download the desired language pack(s) by selecting the `.traineddata` file(s) for the language(s) you need. 2. Place the `.traineddata` files in the Tesseract tessdata directory: `/usr/share/tessdata` 3. Please view [OCRmyPDF install guide](https://ocrmypdf.readthedocs.io/en/latest/installation.html) for more info. **IMPORTANT:** DO NOT REMOVE EXISTING `eng.traineddata`, IT'S REQUIRED. Debian based systems, install languages with this command: ```bash sudo apt update &&\ # All languages # sudo apt install -y 'tesseract-ocr-*' # Find languages: apt search tesseract-ocr- # View installed languages: dpkg-query -W tesseract-ocr- | sed 's/tesseract-ocr-//g' ``` Fedora: ```bash # All languages # sudo dnf install -y tesseract-langpack-* # Find languages: dnf search -C tesseract-langpack- # View installed languages: rpm -qa | grep tesseract-langpack | sed 's/tesseract-langpack-//g' ``` ### Step 7: Run Stirling-PDF ```bash ./gradlew bootRun or java -jar /opt/Stirling-PDF/Stirling-PDF-*.jar ``` ### Step 8: Adding a Desktop icon This will add a modified Appstarter to your Appmenu. ```bash location=$(pwd)/gradlew image=$(pwd)/docs/stirling-transparent.svg cat > ~/.local/share/applications/Stirling-PDF.desktop <
