DBus Installation
=================
Quick start
===========
This branch of dbus can be built by using Meson or CMake.
The Meson build system is the recommended build system for the master
branch (versions >= 1.15.0), except when building on Windows, for which
CMake is recommended (this recommendation might change to Meson in future).
Meson only supports out-of-tree builds, and must be passed a directory to put
built and generated sources into. We'll call that directory "build" here. It's
recommended to create a separate build directory for each configuration you
might want to use.
Basic configuration is done with:
``` sh
meson build/
```
This will create the build directory. If any dependencies are missing, you can
install them, or try to remove the dependency with a Meson configuration option
(see below).
Older versions of dbus required Autotools or CMake, with Autotools
recommended for Unix systems and CMake recommended for Windows systems.
Configuration flags
===================
When using Meson, to review the options which Meson chose, run:
``` sh
meson configure build/
```
With additional arguments meson configure can be used to change options for a
previously configured build directory. All options passed to this command are in
the form `-D "option"="value"`. For example:
``` sh
meson configure build/ -Dprefix=/tmp/install
```
See `meson_options.txt` for details of dbus-specific options, and
<https://mesonbuild.com/Builtin-options.html> for details of generic
Meson options.
When using CMake, inspect README.cmake to see the possible
configuration options and environment variables.
Building
========
To build with meson, here is a quick guide:
``` sh
cd dbus
meson setup build/ && cd build/
meson compile
meson test
```
Full build instructions can be found on mesonbuild website:
https://mesonbuild.com/Running-Meson.html
Building with CMake
-------------------
The CMake equivalent is:
``` sh
cd <dbus-src-root>
cmake -G <makefile-generator-name> [-D<option>] -B dbus-build-dir
cmake --build <dbus-build-dir>
cmake --build <dbus-build-dir> -t check
```
The installation of the build with CMake is performed with:
``` sh
cmake --build <dbus-build-dir> -t install [DESTDIR=<install-dir>]
```
When using makefile generator `-t install/fast` can also be used,
which prevents rebuilding.
CMake will automatically determine whether to build some features
based on what tools and/or libraries are installed on the host system.
The default build behaviour can be overridden using the
-DENABLE_<XXX> arguments to cmake.
A typical scenario in which it is desirable to override automatic
detection, is during packaging of binary builds, where a predictable
dependancy chain is required. For more details on cmake installation,
consult http://www.cmake.org/cmake/help/help.html.
