Installation instructions

DDM uses CMake to configure and build the project.

  1. From the project root, create a build directory: mkdir build
  2. From the build directory, run cmake to the project root. Eg: cd build && cmake ..
  3. To build, run make.
  4. To install, run make install.

CMake accepts a number of standard and extra arguments:

  • BUILD_MAN_PAGES, pass -DBUILD_MAN_PAGES=ON to build man pages
  • ENABLE_JOURNALD, pass -DENABLE_JOURNALD=OFF to disable logging to the journal

By default, a debug build is created. To build for production, use cmake -DCMAKE_BUILD_TYPE=Release.

To see all the possible arguments, run cmake -L ... For documentation on standard CMake variables, see: http://www.cmake.org/cmake/help/v3.0/manual/cmake-variables.7.html

Post-installation steps

By default, DDM runs as its own user. An ddm user needs to be created, with its home set to /var/lib/ddm by default.

Dependencies

DDM depends on PAM for authorization and XCB to communicate with the X server. Apart from other things, it also depends on Qt for the user interface and event loop management. DDM can optionally make use of logind (the systemd login manager API), or ConsoleKit2, or upower to enable support for suspend, hibernate etc. In order to build the man pages, you will need rst2man installed. It is provided by the python docutils package

Note that DDM makes use of C++11 features for a modern and clean codebase, therefore it needs a recent version of GCC to compile (4.7 at least).
