1 DBus Installation 2 ================= 3 4 Quick start 5 =========== 6 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: 9 10 with autotools: 11 12 ./configure --prefix=/usr 13 make 14 su make install 15 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 24 25 with cmake: 26 mkdir dbus-build-dir 27 cd dbus-build-dir 28 cmake -G <makefile-generator-name> [-D<option>] <dbus-src-root>/cmake 29 make 30 make install 31 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. 40 41 External software dependancies 42 ============================== 43 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. 47 48 Core library 49 ------------ 50 51 Requisite: 52 53 - Gettext 54 - expat or libxml-2 55 56 NB, expat is the recommended XML parser because it has more robust 57 handling of OOM conditions. 58 59 Optional: 60 61 - libselinux (for SELinux integration) 62 - dnotify (for automatic service file reload) 63 - doxygen (for API documentation) 64 - xmlto or meinproc4 (for Spec & other XML documentation) 65 66 ==================================================================== 67 68 The rest of this document contains the generic GNU AutoTools install 69 insructions.... 70 71 Basic Installation 72 ================== 73 74 These are generic installation instructions. 75 76 The `configure' shell script attempts to guess correct values for 77 various system-dependent variables used during compilation. It uses 78 those values to create a `Makefile' in each directory of the package. 79 It may also create one or more `.h' files containing system-dependent 80 definitions. Finally, it creates a shell script `config.status' that 81 you can run in the future to recreate the current configuration, a file 82 `config.cache' that saves the results of its tests to speed up 83 reconfiguring, and a file `config.log' containing compiler output 84 (useful mainly for debugging `configure'). 85 86 If you need to do unusual things to compile the package, please try 87 to figure out how `configure' could check whether to do them, and mail 88 diffs or instructions to the address given in the `README' so they can 89 be considered for the next release. If at some point `config.cache' 90 contains results you don't want to keep, you may remove or edit it. 91 92 The file `configure.in' is used to create `configure' by a program 93 called `autoconf'. You only need `configure.in' if you want to change 94 it or regenerate `configure' using a newer version of `autoconf'. 95 96 The simplest way to compile this package is: 97 98 1. `cd' to the directory containing the package's source code and type 99 `./configure' to configure the package for your system. If you're 100 using `csh' on an old version of System V, you might need to type 101 `sh ./configure' instead to prevent `csh' from trying to execute 102 `configure' itself. 103 104 Running `configure' takes awhile. While running, it prints some 105 messages telling which features it is checking for. 106 107 2. Type `make' to compile the package. 108 109 3. Optionally, type `make check' to run any self-tests that come with 110 the package. 111 112 4. Type `make install' to install the programs and any data files and 113 documentation. 114 115 5. You can remove the program binaries and object files from the 116 source code directory by typing `make clean'. To also remove the 117 files that `configure' created (so you can compile the package for 118 a different kind of computer), type `make distclean'. There is 119 also a `make maintainer-clean' target, but that is intended mainly 120 for the package's developers. If you use it, you may have to get 121 all sorts of other programs in order to regenerate files that came 122 with the distribution. 123 124 Compilers and Options 125 ===================== 126 127 Some systems require unusual options for compilation or linking that 128 the `configure' script does not know about. You can give `configure' 129 initial values for variables by setting them in the environment. Using 130 a Bourne-compatible shell, you can do that on the command line like 131 this: 132 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure 133 134 Or on systems that have the `env' program, you can do it like this: 135 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 136 137 Compiling For Multiple Architectures 138 ==================================== 139 140 You can compile the package for more than one kind of computer at the 141 same time, by placing the object files for each architecture in their 142 own directory. To do this, you must use a version of `make' that 143 supports the `VPATH' variable, such as GNU `make'. `cd' to the 144 directory where you want the object files and executables to go and run 145 the `configure' script. `configure' automatically checks for the 146 source code in the directory that `configure' is in and in `..'. 147 148 If you have to use a `make' that does not supports the `VPATH' 149 variable, you have to compile the package for one architecture at a time 150 in the source code directory. After you have installed the package for 151 one architecture, use `make distclean' before reconfiguring for another 152 architecture. 153 154 Installation Names 155 ================== 156 157 By default, `make install' will install the package's files in 158 `/usr/local/bin', `/usr/local/man', etc. You can specify an 159 installation prefix other than `/usr/local' by giving `configure' the 160 option `--prefix=PATH'. 161 162 You can specify separate installation prefixes for 163 architecture-specific files and architecture-independent files. If you 164 give `configure' the option `--exec-prefix=PATH', the package will use 165 PATH as the prefix for installing programs and libraries. 166 Documentation and other data files will still use the regular prefix. 167 168 In addition, if you use an unusual directory layout you can give 169 options like `--bindir=PATH' to specify different values for particular 170 kinds of files. Run `configure --help' for a list of the directories 171 you can set and what kinds of files go in them. 172 173 If the package supports it, you can cause programs to be installed 174 with an extra prefix or suffix on their names by giving `configure' the 175 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 176 177 Optional Features 178 ================= 179 180 Some packages pay attention to `--enable-FEATURE' options to 181 `configure', where FEATURE indicates an optional part of the package. 182 They may also pay attention to `--with-PACKAGE' options, where PACKAGE 183 is something like `gnu-as' or `x' (for the X Window System). The 184 `README' should mention any `--enable-' and `--with-' options that the 185 package recognizes. 186 187 For packages that use the X Window System, `configure' can usually 188 find the X include and library files automatically, but if it doesn't, 189 you can use the `configure' options `--x-includes=DIR' and 190 `--x-libraries=DIR' to specify their locations. 191 192 Specifying the System Type 193 ========================== 194 195 There may be some features `configure' can not figure out 196 automatically, but needs to determine by the type of host the package 197 will run on. Usually `configure' can figure that out, but if it prints 198 a message saying it can not guess the host type, give it the 199 `--host=TYPE' option. TYPE can either be a short name for the system 200 type, such as `sun4', or a canonical name with three fields: 201 CPU-COMPANY-SYSTEM 202 203 See the file `config.sub' for the possible values of each field. If 204 `config.sub' isn't included in this package, then this package doesn't 205 need to know the host type. 206 207 If you are building compiler tools for cross-compiling, you can also 208 use the `--target=TYPE' option to select the type of system they will 209 produce code for and the `--build=TYPE' option to select the type of 210 system on which you are compiling the package. 211 212 Sharing Defaults 213 ================ 214 215 If you want to set default values for `configure' scripts to share, 216 you can create a site shell script called `config.site' that gives 217 default values for variables like `CC', `cache_file', and `prefix'. 218 `configure' looks for `PREFIX/share/config.site' if it exists, then 219 `PREFIX/etc/config.site' if it exists. Or, you can set the 220 `CONFIG_SITE' environment variable to the location of the site script. 221 A warning: not all `configure' scripts look for a site script. 222 223 Operation Controls 224 ================== 225 226 `configure' recognizes the following options to control how it 227 operates. 228 229 `--cache-file=FILE' 230 Use and save the results of the tests in FILE instead of 231 `./config.cache'. Set FILE to `/dev/null' to disable caching, for 232 debugging `configure'. 233 234 `--help' 235 Print a summary of the options to `configure', and exit. 236 237 `--quiet' 238 `--silent' 239 `-q' 240 Do not print messages saying which checks are being made. To 241 suppress all normal output, redirect it to `/dev/null' (any error 242 messages will still be shown). 243 244 `--srcdir=DIR' 245 Look for the package's source code in directory DIR. Usually 246 `configure' can determine that directory automatically. 247 248 `--version' 249 Print the version of Autoconf used to generate the `configure' 250 script, and exit. 251 252 `configure' also accepts some other, not widely useful, options. 253
