Linux Build

Introduction

Xournal++ is programmed with C++20. Therefore it is required to install a compiler implementing those features. We recommend using at least GCC 11 or Clang 15.

Please file an issue or create a pull request if you require more precise dependencies.

Lua is needed for plugins; if it is missing, the plugins will be disabled.

Install Dependencies

The minimum required CMake version is 3.13, but we recommend using >=3.15. Also, ninja must be installed (the cpptrace dependency uses C++20 modules, which are not supported by the Unix Makefiles generator).

For Arch Linux:

sudo pacman -S cmake ninja gtk3 base-devel libxml2 portaudio libsndfile \
  poppler-glib texlive-bin texlive-pictures libzip lua \
  gtksourceview4 help2man qpdf

For Fedora:

sudo dnf install gcc-c++ cmake ninja-build gtk3-devel libxml2-devel portaudio-devel libsndfile-devel \
  poppler-glib-devel texlive-scheme-basic texlive-dvipng 'tex(standalone.cls)' gettext libzip-devel \
  librsvg2-devel lua-devel gtksourceview4-devel help2man qpdf-devel

For CentOS/RHEL:

sudo dnf install gcc-c++ cmake ninja-build gtk3-devel libxml2-devel cppunit-devel portaudio-devel libsndfile-devel \
  poppler-glib-devel texlive-scheme-basic texlive-dvipng 'tex(standalone.cls)' gettext libzip-devel \
  librsvg2-devel gtksourceview4-devel qpdf-devel

For Ubuntu/Debian and Raspberry Pi OS:

sudo apt-get install cmake ninja-build libgtk-3-dev libpoppler-glib-dev portaudio19-dev libsndfile-dev \
  dvipng texlive libxml2-dev liblua5.4-dev libzip-dev librsvg2-dev gettext \
  libgtksourceview-4-dev help2man libqpdf-dev

For openSUSE:

sudo zypper install gcc-c++ cmake ninja gtk3-devel portaudio-devel libsndfile-devel \
  texlive-dvipng texlive libxml2-devel libpoppler-glib-devel libzip-devel librsvg-devel lua-devel \
  gtksourceview4-devel lsb-release help2man qpdf-devel

For Solus:

sudo eopkg it -c system.devel
sudo eopkg it cmake ninja libgtk-3-devel libxml2-devel poppler-devel libzip-devel \
  portaudio-devel libsndfile-devel alsa-lib-devel lua-devel \
  librsvg-devel gettext libgtksourceview-devel qpdf-devel

Building and Testing

See Compile.md

Building Documentation

The code documentation is generated using Doxygen. Both Doxygen and graphviz must be installed. For example, with apt:

sudo apt install doxygen graphviz

Then, execute doxygen in the root directory of the repository. The documentation can be found in doc/html and doc/latex. Launch a server hosting the files with python3 -m http.server 8000 and visit the URL that the command shows.

Packaging and Installation

.deb packages

cmake .. -DCPACK_GENERATOR="DEB" -G Ninja
cmake --build . --target package

.rpm packages

TODO

AppImage

The quickest way to generate an AppImage is to first generate the .tar.gz package and then use that with the linux-setup/build_appimage.sh script.

cmake .. -DCPACK_GENERATOR="TGZ" -G Ninja
cmake --build . --target package
../linux-setup/build_appimage.sh

The build_appimage.sh script will automatically download LinuxDeploy, copy the .tar.gz files and required libraries and resources into a appimage_staging directory, and run LinuxDeploy on the prepared app dir.

By default, the build_appimage.sh script will copy the Adwaita GTK theme and the Adwaita icon theme into the AppImage.

Flatpak

The Flatpak manifest for Xournal++ is located at https://github.com/flathub/com.github.xournalpp.xournalpp, which should be cloned into a separate directory before building.

git clone https://github.com/flathub/com.github.xournalpp.xournalpp xournalpp-flatpak
cd xournalpp-flatpak

By default, the Flatpak manifest will build the latest stable version of Xournal++. You can change the built version to a specific commit by editing the commit information of the manifest to the desired commit (also specify tags if building a stable version):

   - name: xournalpp
     buildsystem: cmake-ninja
     sources:
       - type: git
         url: https://github.com/xournalpp/xournalpp
-        commit: 14e9012b94e005112387dbb7d2ed59274d542885
-        tag: 1.0.10
+        commit: a911a3911df7c588c23997a29ad6a2e8d48b4aea
+        tag: 1.0.15

You can also build your local clone of Xournal++ by changing the source type to dir and specifying the path to the clone.

Installation from source

We highly discourage installation from source, as it may lead to issues when upgrading to newer versions later on. Please think about creating a native package, an AppImage or Flatpak instead. Instructions are above.

If you don't want to make a package, you can install Xournal++ into your user folder (or any other folder) by specifying CMAKE_INSTALL_PREFIX:

cmake .. -DCMAKE_INSTALL_PREFIX="$HOME/.local" -G Ninja
cmake --build . --target install
./cmake/postinst configure

If you want to install Xournal++ system-wide directly from the build directory, run

cmake .. -DCMAKE_INSTALL_PREFIX=/usr -G Ninja
sudo cmake --build . --target install
./cmake/postinst configure
