sdbus-c++ 2.1.0
High-level C++ D-Bus library based on systemd D-Bus implementation
|
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:
SDBUSCPP_BUILD_CODEGEN [boolean]
Build the codegen tool sdbus-c++-xml2cpp for generating the high level C++ bindings out of the D-Bus IDL XML description. Default value: OFF. Use -DSDBUSCPP_BUILD_CODEGEN=ON flag to turn on building the code gen.
SDBUSCPP_BUILD_DOCS [boolean]
Include sdbus-c++ documentation files and tutorials. Default value: ON. With this option turned on, you may also enable/disable the following option:
SDBUSCPP_BUILD_DOXYGEN_DOCS [boolean]
Build Doxygen documentation of sdbus-c++ API. If enabled, the documentation must still be built explicitly through cmake --build . --target doc. Default value: OFF. Use -DSDBUSCPP_BUILD_DOXYGEN_DOCS=OFF to disable searching for Doxygen and building Doxygen documentation of sdbus-c++ API.
SDBUSCPP_BUILD_TESTS [boolean]
Build sdbus-c++ unit and integration tests, invokable by cmake --build . --target test (Note: before invoking cmake --build . --target test, make sure you copy tests/integrationtests/files/org.sdbuscpp.integrationtests.conf file to /etc/dbus-1/system.d directory). 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:
SDBUSCPP_BUILD_PERF_TESTS [boolean]
Build sdbus-c++ performance tests. Default value: OFF.
SDBUSCPP_BUILD_STRESS_TESTS [boolean]
Build sdbus-c++ stress tests. Default value: OFF.
SDBUSCPP_TESTS_INSTALL_PATH [string]
Path where the test binaries shall get installed. Default value: ${CMAKE_INSTALL_PREFIX}/tests/sdbus-c++ (previously: /opt/test/bin).
SDBUSCPP_BUILD_EXAMPLES [boolean]
Build example programs which are located in the example directory. Examples are not installed. Default value: OFF.
SDBUSCPP_BUILD_LIBSYSTEMD [boolean]
Build sd-bus (libsystemd library) instead of searching for it in the system, and make it part of sdbus-c++ library. Default value: OFF, which means that the sd-bus implementation library (libsystemd, libelogind, or basu) will be searched via pkg-config in the system.
This option may be very helpful in environments where sd-bus implementation library is unavailable (see Solving sd-bus dependency for more information).
With this option turned off, you may provide the following additional configuration flag:
SDBUSCPP_SDBUS_LIB [string]
Defines which sd-bus implementation library to search for and use. Allowed values: default, systemd, elogind, basu. Default value: default, which means that sdbus-c++ will try to find any of systemd, elogind, basu in the order as listed here.
With this option turned on, you may provide the following additional configuration flag:
SDBUSCPP_LIBSYSTEMD_VERSION [string]
Defines version of systemd to be downloaded, built and integrated into sdbus-c++. Default value: 252, minimum value: 239.
SDBUSCPP_LIBSYSTEMD_EXTRA_CONFIG_OPTS [string]
Additional options to be passed as-is to the libsystemd build system in its configure step. Can be used for passing e.g. toolchain file path in case of cross builds. Default value: empty.
CMAKE_BUILD_TYPE [string]
CMake-builtin option. Set to Release to build sdbus-c++ for production use. Set to Debug if you want to help further develop (and debug) the library :)
BUILD_SHARED_LIBS [boolean]
Global CMake flag, promoted in sdbus-c++ project to a CMake option. Use this to control whether sdbus-c++ is built as either a shared or static library. Default value: ON.
The library is distributed under LGPLv2.1 license, with a specific exception for macro/template/inline code in library header files.
