sdbus-c++ is a C++ D-Bus library meant to provide high-level, expressive, easy-to-use interfaces in modern C++. It adds another layer of abstraction on top of sd-bus, a nice, fresh C D-Bus implementation by systemd.

sdbus-c++ has been written primarily as a replacement of dbus-c++, which currently suffers from a number of (unsolved) bugs, concurrency issues and inherent design limitations. sdbus-c++ has learned from dbus-c++ and tries to come up with a simple design that is flexible and friendly to the user and inherently free of those bugs.

Building and installing the library

The library is built using CMake:

$ mkdir build
$ cd build
$ cmake .. ${CONFIGURE_FLAGS_IF_NECESSARY}
$ make
$ sudo make install

CMake configuration flags

BUILD_CODE_GEN [boolean]

Option for building the stub code generator sdbus-c++-xml2cpp for generating the adaptor and proxy interfaces out of the D-Bus IDL XML description. Default value: OFF. Use -DBUILD_CODE_GEN=ON flag to turn on building the code gen.
BUILD_DOC [boolean]

Option for including sdbus-c++ documentation files and tutorials. Default value: ON. With this option turned on, you may also enable/disable the following option:
- BUILD_DOXYGEN_DOC [boolean]
  
  Option for building Doxygen documentation of sdbus-c++ API. If enabled, the documentation must still be built explicitly through make doc. Default value: OFF. Use -DBUILD_DOXYGEN_DOC=OFF to disable searching for Doxygen and building Doxygen documentation of sdbus-c++ API.
BUILD_TESTS [boolean]

Option for building sdbus-c++ unit and integration tests, invokable by make test. That incorporates downloading and building static libraries of Google Test. Default value: OFF. Use -DBUILD_TESTS=ON to enable building the tests. With this option turned on, you may also enable/disable the following options:
- BUILD_PERF_TESTS [boolean]
  
  Option for building sdbus-c++ performance tests. Default value: OFF.
- BUILD_STRESS_TESTS [boolean]
  
  Option for building sdbus-c++ stress tests. Default value: OFF.
- TESTS_INSTALL_PATH [string]
  
  Path where the test binaries shall get installed. Default value: /opt/test/bin.

Dependencies

C++17 - the library uses C++17 std::uncaught_exceptions() feature. When building sdbus-c++ manually, make sure you use a compiler that supports that feature (gcc >= 6, clang >= 3.7)
libsystemd - systemd library containing sd-bus implementation. This library is part of systemd. Systemd at least v236 is needed. (Non-systemd environments are also supported, see the tutorial for more information.)
googletest - google unit testing framework, only necessary when building tests, will be downloaded and built automatically.

Licensing

The library is distributed under LGPLv2.1 license.
