7 DBus uses GNU AutoTools for its build system, thus the basic install
8 procedure can be summarized as:
10 ./configure --prefix=/usr
14 The configure script will automatically determine whether to try and
15 build bindings for GLib, Qt, Qt3, Python and Mono based on what tools
16 are installed on the host system. The default build behaviour can be
17 overridden using the --enable-XXX/--disable-XXX arguments to configure.
18 A typical scenario in which it is desirable to override automatic
19 detection, is during packaging of binary builds, where a predictable
20 dependancy chain is required. For more details on GNU AutoTools
21 installation, consult the generic instructions later in this document
23 External software dependancies
24 ==============================
26 The only fundamental requirement to build DBus is an XML parser,
27 however, there are a number of other software packages which (if
28 present) will enhance functionality.
38 NB, expat is the recommended XML parser because it has more robust
39 handling of OOM conditions.
43 - libselinux (for SELinux integration)
44 - dnotify (for automatic service file reload)
45 - doxygen (for API documentation)
46 - xmlto (for Spec & other XML documentation)
57 - GTK+ >= 2.4 (for dbus-viewer tool)
64 - QtCore and QtXml >= 4.1.3
68 - QtTest (for Qt Unit tests)
69 - QtGui >= 4.1.3 (for the chat example program)
71 Note: Qt 4.1.3 is not available in released form. You need to download
72 the 4.1.3 snapshots from Trolltech. However, the Qt binding compiles
73 and works in Qt 4.1.2, but not the dbusidl2cpp tool.
75 Note that DBus detects QtCore and QtXml during the configure process
76 using pkg-config. You may need to set the PKG_CONFIG_PATH to include
77 the Qt4 library directory. If you don't have your Qt4 installed, then
78 you may also need to use the --with-qt-moc directive to point to the
79 Qt4 moc executable (e.g. $QTDIR/bin/moc).
98 - MonoDoc >= 0.16 (for API documentation)
108 ====================================================================
110 The rest of this document contains the generic GNU AutoTools install
116 These are generic installation instructions.
118 The `configure' shell script attempts to guess correct values for
119 various system-dependent variables used during compilation. It uses
120 those values to create a `Makefile' in each directory of the package.
121 It may also create one or more `.h' files containing system-dependent
122 definitions. Finally, it creates a shell script `config.status' that
123 you can run in the future to recreate the current configuration, a file
124 `config.cache' that saves the results of its tests to speed up
125 reconfiguring, and a file `config.log' containing compiler output
126 (useful mainly for debugging `configure').
128 If you need to do unusual things to compile the package, please try
129 to figure out how `configure' could check whether to do them, and mail
130 diffs or instructions to the address given in the `README' so they can
131 be considered for the next release. If at some point `config.cache'
132 contains results you don't want to keep, you may remove or edit it.
134 The file `configure.in' is used to create `configure' by a program
135 called `autoconf'. You only need `configure.in' if you want to change
136 it or regenerate `configure' using a newer version of `autoconf'.
138 The simplest way to compile this package is:
140 1. `cd' to the directory containing the package's source code and type
141 `./configure' to configure the package for your system. If you're
142 using `csh' on an old version of System V, you might need to type
143 `sh ./configure' instead to prevent `csh' from trying to execute
146 Running `configure' takes awhile. While running, it prints some
147 messages telling which features it is checking for.
149 2. Type `make' to compile the package.
151 3. Optionally, type `make check' to run any self-tests that come with
154 4. Type `make install' to install the programs and any data files and
157 5. You can remove the program binaries and object files from the
158 source code directory by typing `make clean'. To also remove the
159 files that `configure' created (so you can compile the package for
160 a different kind of computer), type `make distclean'. There is
161 also a `make maintainer-clean' target, but that is intended mainly
162 for the package's developers. If you use it, you may have to get
163 all sorts of other programs in order to regenerate files that came
164 with the distribution.
166 Compilers and Options
167 =====================
169 Some systems require unusual options for compilation or linking that
170 the `configure' script does not know about. You can give `configure'
171 initial values for variables by setting them in the environment. Using
172 a Bourne-compatible shell, you can do that on the command line like
174 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
176 Or on systems that have the `env' program, you can do it like this:
177 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
179 Compiling For Multiple Architectures
180 ====================================
182 You can compile the package for more than one kind of computer at the
183 same time, by placing the object files for each architecture in their
184 own directory. To do this, you must use a version of `make' that
185 supports the `VPATH' variable, such as GNU `make'. `cd' to the
186 directory where you want the object files and executables to go and run
187 the `configure' script. `configure' automatically checks for the
188 source code in the directory that `configure' is in and in `..'.
190 If you have to use a `make' that does not supports the `VPATH'
191 variable, you have to compile the package for one architecture at a time
192 in the source code directory. After you have installed the package for
193 one architecture, use `make distclean' before reconfiguring for another
199 By default, `make install' will install the package's files in
200 `/usr/local/bin', `/usr/local/man', etc. You can specify an
201 installation prefix other than `/usr/local' by giving `configure' the
202 option `--prefix=PATH'.
204 You can specify separate installation prefixes for
205 architecture-specific files and architecture-independent files. If you
206 give `configure' the option `--exec-prefix=PATH', the package will use
207 PATH as the prefix for installing programs and libraries.
208 Documentation and other data files will still use the regular prefix.
210 In addition, if you use an unusual directory layout you can give
211 options like `--bindir=PATH' to specify different values for particular
212 kinds of files. Run `configure --help' for a list of the directories
213 you can set and what kinds of files go in them.
215 If the package supports it, you can cause programs to be installed
216 with an extra prefix or suffix on their names by giving `configure' the
217 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
222 Some packages pay attention to `--enable-FEATURE' options to
223 `configure', where FEATURE indicates an optional part of the package.
224 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
225 is something like `gnu-as' or `x' (for the X Window System). The
226 `README' should mention any `--enable-' and `--with-' options that the
229 For packages that use the X Window System, `configure' can usually
230 find the X include and library files automatically, but if it doesn't,
231 you can use the `configure' options `--x-includes=DIR' and
232 `--x-libraries=DIR' to specify their locations.
234 Specifying the System Type
235 ==========================
237 There may be some features `configure' can not figure out
238 automatically, but needs to determine by the type of host the package
239 will run on. Usually `configure' can figure that out, but if it prints
240 a message saying it can not guess the host type, give it the
241 `--host=TYPE' option. TYPE can either be a short name for the system
242 type, such as `sun4', or a canonical name with three fields:
245 See the file `config.sub' for the possible values of each field. If
246 `config.sub' isn't included in this package, then this package doesn't
247 need to know the host type.
249 If you are building compiler tools for cross-compiling, you can also
250 use the `--target=TYPE' option to select the type of system they will
251 produce code for and the `--build=TYPE' option to select the type of
252 system on which you are compiling the package.
257 If you want to set default values for `configure' scripts to share,
258 you can create a site shell script called `config.site' that gives
259 default values for variables like `CC', `cache_file', and `prefix'.
260 `configure' looks for `PREFIX/share/config.site' if it exists, then
261 `PREFIX/etc/config.site' if it exists. Or, you can set the
262 `CONFIG_SITE' environment variable to the location of the site script.
263 A warning: not all `configure' scripts look for a site script.
268 `configure' recognizes the following options to control how it
272 Use and save the results of the tests in FILE instead of
273 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
274 debugging `configure'.
277 Print a summary of the options to `configure', and exit.
282 Do not print messages saying which checks are being made. To
283 suppress all normal output, redirect it to `/dev/null' (any error
284 messages will still be shown).
287 Look for the package's source code in directory DIR. Usually
288 `configure' can determine that directory automatically.
291 Print the version of Autoconf used to generate the `configure'
294 `configure' also accepts some other, not widely useful, options.
