Contributing
Okular uses the merge request workflow. Merge requests are required to run pre-commit CI jobs; please don’t push to the master branch directly. See https://community.kde.org/Infrastructure/GitLab for an introduction.
Build instructions
Okular can be built like many other applications developed by KDE. See https://community.kde.org/Get_Involved/development for an introduction.
If your build environment is set up correctly, you can also build Okular using CMake:
git clone https://invent.kde.org/graphics/okular.git
cd okular
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/path/to/your/install/dir ..
make
make install
Okular also builds tests in the build tree. To run them, you have to run make install
first.
If you install Okular in a different path than your system install directory it is possible that you need to run
source prefix.sh
so that the correct Okular instance and libraries are picked up.
Afterwards one can run okular
inside the shell instance.
The source command is also required to run the tests manually.
As stated above, Okular has various build targets. Two of them are executables. You can choose which executable to build by passing a flag to CMake:
cmake -DCMAKE_INSTALL_PREFIX=/path/to/your/install/dir -DOKULAR_UI=desktop ..
Available options are desktop
, mobile
, and both
.
clang-format
The Okular project uses clang-format to enforce source code formatting. See README.clang_format for more information.
