sdbus-c++ is a high-level C++ D-Bus library for Linux designed to provide expressive, easy-to-use API 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 (unresolved) bugs, concurrency issues and inherent design complexities and limitations. sdbus-c++ has learned from dbus-c++ and has chosen a different path, a path of simple yet powerful design that is intuitive and friendly to the user and inherently free of those bugs.
Even though sdbus-c++ uses sd-bus library, it is not necessarily constrained to systemd and can perfectly be used in non-systemd environments as well.
The library is built using CMake:
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release ${OTHER_CONFIG_FLAGS}
$ make
$ sudo make install-
BUILD_CODE_GEN[boolean]Option for building the stub code generator
sdbus-c++-xml2cppfor generating the adaptor and proxy interfaces out of the D-Bus IDL XML description. Default value:OFF. Use-DBUILD_CODE_GEN=ONflag 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=OFFto 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=ONto 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.
-
-
BUILD_LIBSYSTEMD[boolean]Option for building libsystemd dependency library automatically when sdbus-c++ is built, and making libsystemd an integral part of sdbus-c++ library. Default value:
OFF. Might be very helpful in non-systemd environments where libsystemd shared library is unavailable (see Solving libsystemd dependency for more information). With this option turned on, you may also provide the following configuration flag:-
LIBSYSTEMD_VERSION[string]Defines version of systemd to be downloaded, built and integrated into sdbus-c++. Default value:
242.
-
-
CMAKE_BUILD_TYPE[string]This is a CMake-builtin option. Set to
Releaseto build sdbus-c++ for production use. Set toDebugif you want to help further develop (and debug) the library :)
C++17- the library uses C++17 features.libsystemd- systemd library containing sd-bus implementation. This library is part of systemd. Systemd at least v236 is needed. (In case you have a non-systemd environment, don't worry, see Solving libsystemd dependency for more information.)googletest- google unit testing framework, only necessary when building tests, will be downloaded and built automatically.pkgconfig- required for sdbus-c++ to be able to find some dependency packages.
The library is distributed under LGPLv2.1 license.
