7 DBus could be build with GNU AutoTools or with cmake for its build system,
8 thus the basic install procedure can be summarized as:
12 ./configure --prefix=/usr
16 The configure script will automatically determine whether to try and
17 build bindings for GLib, Qt, Qt3, Python and Mono based on what tools
18 are installed on the host system. The default build behaviour can be
19 overridden using the --enable-XXX/--disable-XXX arguments to configure.
20 A typical scenario in which it is desirable to override automatic
21 detection, is during packaging of binary builds, where a predictable
22 dependancy chain is required. For more details on GNU AutoTools
23 installation, consult the generic instructions later in this document
28 cmake -G <makefile-generator-name> [-D<option>] <dbus-src-root>/cmake
32 cmake will automatically determine whether to build some features
33 based on what tools and/or libraries are installed on the host system.
34 The default build behaviour can be overridden using the
35 -DENABLE_<XXX> arguments to cmake.
36 A typical scenario in which it is desirable to override automatic
37 detection, is during packaging of binary builds, where a predictable
38 dependancy chain is required. For more details on cmake installation,
39 consult http://www.cmake.org/cmake/help/help.html.
41 External software dependancies
42 ==============================
44 The only fundamental requirement to build DBus is an XML parser,
45 however, there are a number of other software packages which (if
46 present) will enhance functionality.
58 - libselinux (for SELinux integration)
59 - dnotify (for automatic service file reload)
60 - doxygen (for API documentation)
61 - xmlto or meinproc4 (for Spec & other XML documentation)
63 ====================================================================
65 The rest of this document contains the generic GNU AutoTools install
71 These are generic installation instructions.
73 The `configure' shell script attempts to guess correct values for
74 various system-dependent variables used during compilation. It uses
75 those values to create a `Makefile' in each directory of the package.
76 It may also create one or more `.h' files containing system-dependent
77 definitions. Finally, it creates a shell script `config.status' that
78 you can run in the future to recreate the current configuration, a file
79 `config.cache' that saves the results of its tests to speed up
80 reconfiguring, and a file `config.log' containing compiler output
81 (useful mainly for debugging `configure').
83 If you need to do unusual things to compile the package, please try
84 to figure out how `configure' could check whether to do them, and mail
85 diffs or instructions to the address given in the `README' so they can
86 be considered for the next release. If at some point `config.cache'
87 contains results you don't want to keep, you may remove or edit it.
89 The file `configure.in' is used to create `configure' by a program
90 called `autoconf'. You only need `configure.in' if you want to change
91 it or regenerate `configure' using a newer version of `autoconf'.
93 The simplest way to compile this package is:
95 1. `cd' to the directory containing the package's source code and type
96 `./configure' to configure the package for your system. If you're
97 using `csh' on an old version of System V, you might need to type
98 `sh ./configure' instead to prevent `csh' from trying to execute
101 Running `configure' takes awhile. While running, it prints some
102 messages telling which features it is checking for.
104 2. Type `make' to compile the package.
106 3. Optionally, type `make check' to run any self-tests that come with
109 4. Type `make install' to install the programs and any data files and
112 5. You can remove the program binaries and object files from the
113 source code directory by typing `make clean'. To also remove the
114 files that `configure' created (so you can compile the package for
115 a different kind of computer), type `make distclean'. There is
116 also a `make maintainer-clean' target, but that is intended mainly
117 for the package's developers. If you use it, you may have to get
118 all sorts of other programs in order to regenerate files that came
119 with the distribution.
121 Compilers and Options
122 =====================
124 Some systems require unusual options for compilation or linking that
125 the `configure' script does not know about. You can give `configure'
126 initial values for variables by setting them in the environment. Using
127 a Bourne-compatible shell, you can do that on the command line like
129 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
131 Or on systems that have the `env' program, you can do it like this:
132 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
134 Compiling For Multiple Architectures
135 ====================================
137 You can compile the package for more than one kind of computer at the
138 same time, by placing the object files for each architecture in their
139 own directory. To do this, you must use a version of `make' that
140 supports the `VPATH' variable, such as GNU `make'. `cd' to the
141 directory where you want the object files and executables to go and run
142 the `configure' script. `configure' automatically checks for the
143 source code in the directory that `configure' is in and in `..'.
145 If you have to use a `make' that does not supports the `VPATH'
146 variable, you have to compile the package for one architecture at a time
147 in the source code directory. After you have installed the package for
148 one architecture, use `make distclean' before reconfiguring for another
154 By default, `make install' will install the package's files in
155 `/usr/local/bin', `/usr/local/man', etc. You can specify an
156 installation prefix other than `/usr/local' by giving `configure' the
157 option `--prefix=PATH'.
159 You can specify separate installation prefixes for
160 architecture-specific files and architecture-independent files. If you
161 give `configure' the option `--exec-prefix=PATH', the package will use
162 PATH as the prefix for installing programs and libraries.
163 Documentation and other data files will still use the regular prefix.
165 In addition, if you use an unusual directory layout you can give
166 options like `--bindir=PATH' to specify different values for particular
167 kinds of files. Run `configure --help' for a list of the directories
168 you can set and what kinds of files go in them.
170 If the package supports it, you can cause programs to be installed
171 with an extra prefix or suffix on their names by giving `configure' the
172 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
177 Some packages pay attention to `--enable-FEATURE' options to
178 `configure', where FEATURE indicates an optional part of the package.
179 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
180 is something like `gnu-as' or `x' (for the X Window System). The
181 `README' should mention any `--enable-' and `--with-' options that the
184 For packages that use the X Window System, `configure' can usually
185 find the X include and library files automatically, but if it doesn't,
186 you can use the `configure' options `--x-includes=DIR' and
187 `--x-libraries=DIR' to specify their locations.
189 Specifying the System Type
190 ==========================
192 There may be some features `configure' can not figure out
193 automatically, but needs to determine by the type of host the package
194 will run on. Usually `configure' can figure that out, but if it prints
195 a message saying it can not guess the host type, give it the
196 `--host=TYPE' option. TYPE can either be a short name for the system
197 type, such as `sun4', or a canonical name with three fields:
200 See the file `config.sub' for the possible values of each field. If
201 `config.sub' isn't included in this package, then this package doesn't
202 need to know the host type.
204 If you are building compiler tools for cross-compiling, you can also
205 use the `--target=TYPE' option to select the type of system they will
206 produce code for and the `--build=TYPE' option to select the type of
207 system on which you are compiling the package.
212 If you want to set default values for `configure' scripts to share,
213 you can create a site shell script called `config.site' that gives
214 default values for variables like `CC', `cache_file', and `prefix'.
215 `configure' looks for `PREFIX/share/config.site' if it exists, then
216 `PREFIX/etc/config.site' if it exists. Or, you can set the
217 `CONFIG_SITE' environment variable to the location of the site script.
218 A warning: not all `configure' scripts look for a site script.
223 `configure' recognizes the following options to control how it
227 Use and save the results of the tests in FILE instead of
228 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
229 debugging `configure'.
232 Print a summary of the options to `configure', and exit.
237 Do not print messages saying which checks are being made. To
238 suppress all normal output, redirect it to `/dev/null' (any error
239 messages will still be shown).
242 Look for the package's source code in directory DIR. Usually
243 `configure' can determine that directory automatically.
246 Print the version of Autoconf used to generate the `configure'
249 `configure' also accepts some other, not widely useful, options.
