17 You need the following libraries installed before building Omega. If you
18 install these from packages, make sure you install any corresponding -dev or
19 -devel packages as well:
21 * zlib <https://www.zlib.net/>
22 * PCRE2 <https://www.pcre.org/>
23 * libmagic (which comes with the file program
24 <https://www.darwinsys.com/file/>) - on RPM-based package systems, the
25 package with the header in is often named file-devel
27 Quick Installation Guide
28 ========================
30 The simplest way to compile this package is:
32 1. 'cd' to the directory containing the package's source code and type
33 './configure' to configure the package for your system.
35 You need to make sure that xapian-config from xapian-core is on your path,
36 or else pass its full path to omega's configure script:
38 ./configure XAPIAN_CONFIG=/path/to/xapian-config
40 Running 'configure' might take a while. While running, it prints
41 some messages telling which features it is checking for.
43 2. Type 'make' to compile the package.
45 3. Optionally, type 'make check' to run the self-tests that come with
46 the package, using the just-built uninstalled binaries.
48 4. Type 'make install' to install the programs and any data files and
49 documentation. When installing into a prefix owned by root, it is
50 recommended that the package be configured and built as a regular
51 user, and only the 'make install' phase executed with root
54 5. You can remove the program binaries and object files from the
55 source code directory by typing 'make clean'. To also remove the
56 files that 'configure' created (so you can compile the package for
57 a different kind of computer), type 'make distclean'. There is
58 also a 'make maintainer-clean' target, but that is intended mainly
59 for the package's developers. If you use it, you may have to get
60 all sorts of other programs in order to regenerate files that came
61 with the distribution.
63 6. You can also type 'make uninstall' to remove the installed files
69 Some systems may require unusual options for compilation or linking that
70 the 'configure' script does not know about. Run './configure --help'
71 for details on some of the pertinent environment variables.
73 You can give 'configure' initial values for configuration parameters
74 by setting variables in the command line or in the environment. Here
77 ./configure CXX=g++-4.9 CFLAGS=-O2 LIBS=-lposix
79 If your system requires special flags, do let us know. Where possible
80 we'd prefer configure to determine such flags by itself, but if we can't
81 then at least we can document the special flags to help other users of
84 Compiling For Multiple Architectures
85 ====================================
87 When using GCC on platforms which support multiple architectures, the simplest
88 way to select a non-default architecture is to pass a CXX setting to configure
89 which includes the appropriate -m option - e.g. to build for x86 on x86-64
90 you would configure with:
92 ./configure CXX='g++ -m32'
94 On macOS 10.5 and later systems, you can create libraries and
95 executables that work on multiple system types--known as "fat" or
96 "universal" binaries--by specifying multiple '-arch' options to the
97 compiler but only a single '-arch' option to the preprocessor. Like
100 ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
101 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
102 CPP="gcc -E" CXXCPP="g++ -E"
104 Building in a separate directory
105 ================================
107 If you wish to perform your build in a separate directory from the source,
108 create and change to the build directory, and run the configure script (in
109 the source directory) from the build directory, like so:
118 By default, 'make install' installs the package's commands under
119 '/usr/local/bin', include files under '/usr/local/include', etc. You
120 can specify an installation prefix other than '/usr/local' by giving
121 'configure' the option '--prefix=PREFIX', where PREFIX must be an
124 You can specify separate installation prefixes for
125 architecture-specific files and architecture-independent files. If you
126 pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
127 PREFIX as the prefix for installing programs and libraries.
128 Documentation and other data files still use the regular prefix.
130 In addition, if you use an unusual directory layout you can give
131 options like '--bindir=DIR' to specify different values for particular
132 kinds of files. Run 'configure --help' for a list of the directories
133 you can set and what kinds of files go in them.
135 Specifying the System Type
136 ==========================
138 There may be some features 'configure' cannot figure out
139 automatically, but needs to determine by the type of machine the package
140 will run on. Usually, assuming the package is built to be run on the
141 _same_ architectures, 'configure' can figure that out, but if it prints
142 a message saying it cannot guess the machine type, give it the
143 '--build=TYPE' option. TYPE can either be a short name for the system
144 type, such as 'sun4', or a canonical name which has the form:
148 where SYSTEM can have one of these forms:
153 See the file 'config.sub' for the possible values of each field. If
154 'config.sub' isn't included in this package, then this package doesn't
155 need to know the machine type.
157 If you want to _use_ a cross compiler, that generates code for a
158 platform different from the build platform, you should specify the
159 "host" platform (i.e., that on which the generated programs will
160 eventually be run) with '--host=TYPE'.
165 If you want to set default values for 'configure' scripts to share,
166 you can create a site shell script called 'config.site' that gives
167 default values for variables like 'CXX', 'cache_file', and 'prefix'.
168 'configure' looks for 'PREFIX/share/config.site' if it exists, then
169 'PREFIX/etc/config.site' if it exists. Or, you can set the
170 'CONFIG_SITE' environment variable to the location of the site script.
171 A warning: not all 'configure' scripts look for a site script.
176 Variables not defined in a site shell script can be set in the
177 environment passed to 'configure'. However, some packages may run
178 configure again during the build, and the customized values of these
179 variables may be lost. In order to avoid this problem, you should set
180 them in the 'configure' command line, using 'VAR=value'. For example:
182 ./configure CXX=/usr/local2/bin/g++
184 causes the specified 'g++' to be used as the C++ compiler (unless it is
185 overridden in the site shell script).
187 'configure' Invocation
188 ======================
190 'configure' recognizes the following standard options to control how it
195 Print a summary of all of the options to 'configure', and exit.
199 Print the version of Autoconf used to generate the 'configure'
203 Enable the cache: use and save the results of the tests in FILE,
204 traditionally 'config.cache'. FILE defaults to '/dev/null' to
209 Alias for '--cache-file=config.cache'.
214 Do not print messages saying which checks are being made. To
215 suppress all normal output, redirect it to '/dev/null' (any error
216 messages will still be shown).
219 Look for the package's source code in directory DIR. Usually
220 'configure' can determine that directory automatically.
222 'configure' also accepts some other, not widely useful, options. Run
223 'configure --help' for more details.
