10 Basic Installation | |
11 ================== | |
12 | |
13 These are generic installation instructions. | |
14 | |
15 The `configure' shell script attempts to guess correct values for | |
16 various system-dependent variables used during compilation. It uses | |
17 those values to create a `Makefile' in each directory of the package. | |
18 It may also create one or more `.h' files containing system-dependent | |
19 definitions. Finally, it creates a shell script `config.status' that | |
20 you can run in the future to recreate the current configuration, and a | |
21 file `config.log' containing compiler output (useful mainly for | |
22 debugging `configure'). | |
23 | |
24 It can also use an optional file (typically called `config.cache' | |
25 and enabled with `--cache-file=config.cache' or simply `-C') that saves | |
26 the results of its tests to speed up reconfiguring. (Caching is | |
27 disabled by default to prevent problems with accidental use of stale | |
28 cache files.) | |
29 | |
30 If you need to do unusual things to compile the package, please try | |
31 to figure out how `configure' could check whether to do them, and mail | |
32 diffs or instructions to the address given in the `README' so they can | |
33 be considered for the next release. If you are using the cache, and at | |
34 some point `config.cache' contains results you don't want to keep, you | |
35 may remove or edit it. | |
36 | |
37 The file `configure.ac' (or `configure.in') is used to create | |
38 `configure' by a program called `autoconf'. You only need | |
39 `configure.ac' if you want to change it or regenerate `configure' using | |
40 a newer version of `autoconf'. | |
41 | |
42 The simplest way to compile this package is: | |
43 | |
44 1. `cd' to the directory containing the package's source code and type | |
45 `./configure' to configure the package for your system. If you're | |
46 using `csh' on an old version of System V, you might need to type | |
47 `sh ./configure' instead to prevent `csh' from trying to execute | |
48 `configure' itself. | |
49 | |
50 Running `configure' takes awhile. While running, it prints some | |
51 messages telling which features it is checking for. | |
52 | |
53 2. Type `make' to compile the package. | |
54 | |
55 3. Optionally, type `make check' to run any self-tests that come with | |
56 the package. | |
57 | |
58 4. Type `make install' to install the programs and any data files and | |
59 documentation. | |
60 | |
61 5. You can remove the program binaries and object files from the | |
62 source code directory by typing `make clean'. To also remove the | |
63 files that `configure' created (so you can compile the package for | |
64 a different kind of computer), type `make distclean'. There is | |
65 also a `make maintainer-clean' target, but that is intended mainly | |
66 for the package's developers. If you use it, you may have to get | |
67 all sorts of other programs in order to regenerate files that came | |
68 with the distribution. | |
69 | |
70 Compilers and Options | |
71 ===================== | |
72 | |
73 Some systems require unusual options for compilation or linking that the | |
74 `configure' script does not know about. Run `./configure --help' for | |
75 details on some of the pertinent environment variables. | |
76 | |
77 You can give `configure' initial values for configuration parameters | |
78 by setting variables in the command line or in the environment. Here | |
79 is an example: | |
80 | |
81 ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix | |
82 | |
83 *Note Defining Variables::, for more details. | |
84 | |
85 Compiling For Multiple Architectures | |
86 ==================================== | |
87 | |
88 You can compile the package for more than one kind of computer at the | |
89 same time, by placing the object files for each architecture in their | |
90 own directory. To do this, you must use a version of `make' that | |
91 supports the `VPATH' variable, such as GNU `make'. `cd' to the | |
92 directory where you want the object files and executables to go and run | |
93 the `configure' script. `configure' automatically checks for the | |
94 source code in the directory that `configure' is in and in `..'. | |
95 | |
96 If you have to use a `make' that does not support the `VPATH' | |
97 variable, you have to compile the package for one architecture at a | |
98 time in the source code directory. After you have installed the | |
99 package for one architecture, use `make distclean' before reconfiguring | |
100 for another architecture. | |
101 | |
102 Installation Names | |
103 ================== | |
104 | |
105 By default, `make install' will install the package's files in | |
106 `/usr/local/bin', `/usr/local/man', etc. You can specify an | |
107 installation prefix other than `/usr/local' by giving `configure' the | |
108 option `--prefix=PREFIX'. | |
109 | |
110 You can specify separate installation prefixes for | |
111 architecture-specific files and architecture-independent files. If you | |
112 give `configure' the option `--exec-prefix=PREFIX', the package will | |
113 use PREFIX as the prefix for installing programs and libraries. | |
114 Documentation and other data files will still use the regular prefix. | |
115 | |
116 In addition, if you use an unusual directory layout you can give | |
117 options like `--bindir=DIR' to specify different values for particular | |
118 kinds of files. Run `configure --help' for a list of the directories | |
119 you can set and what kinds of files go in them. | |
120 | |
121 If the package supports it, you can cause programs to be installed | |
122 with an extra prefix or suffix on their names by giving `configure' the | |
123 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. | |
124 | |
125 Optional Features | |
126 ================= | |
127 | |
128 Some packages pay attention to `--enable-FEATURE' options to | |
129 `configure', where FEATURE indicates an optional part of the package. | |
130 They may also pay attention to `--with-PACKAGE' options, where PACKAGE | |
131 is something like `gnu-as' or `x' (for the X Window System). The | |
132 `README' should mention any `--enable-' and `--with-' options that the | |
133 package recognizes. | |
134 | |
135 For packages that use the X Window System, `configure' can usually | |
136 find the X include and library files automatically, but if it doesn't, | |
137 you can use the `configure' options `--x-includes=DIR' and | |
138 `--x-libraries=DIR' to specify their locations. | |
139 | |
140 Specifying the System Type | |
141 ========================== | |
142 | |
143 There may be some features `configure' cannot figure out automatically, | |
144 but needs to determine by the type of machine the package will run on. | |
145 Usually, assuming the package is built to be run on the _same_ | |
146 architectures, `configure' can figure that out, but if it prints a | |
147 message saying it cannot guess the machine type, give it the | |
148 `--build=TYPE' option. TYPE can either be a short name for the system | |
149 type, such as `sun4', or a canonical name which has the form: | |
150 | |
151 CPU-COMPANY-SYSTEM | |
152 | |
153 where SYSTEM can have one of these forms: | |
154 | |
155 OS KERNEL-OS | |
156 | |
157 See the file `config.sub' for the possible values of each field. If | |
158 `config.sub' isn't included in this package, then this package doesn't | |
159 need to know the machine type. | |
160 | |
161 If you are _building_ compiler tools for cross-compiling, you should | |
162 use the `--target=TYPE' option to select the type of system they will | |
163 produce code for. | |
164 | |
165 If you want to _use_ a cross compiler, that generates code for a | |
166 platform different from the build platform, you should specify the | |
167 "host" platform (i.e., that on which the generated programs will | |
168 eventually be run) with `--host=TYPE'. | |
169 | |
170 Sharing Defaults | |
171 ================ | |
172 | |
173 If you want to set default values for `configure' scripts to share, you | |
174 can create a site shell script called `config.site' that gives default | |
175 values for variables like `CC', `cache_file', and `prefix'. | |
176 `configure' looks for `PREFIX/share/config.site' if it exists, then | |
177 `PREFIX/etc/config.site' if it exists. Or, you can set the | |
178 `CONFIG_SITE' environment variable to the location of the site script. | |
179 A warning: not all `configure' scripts look for a site script. | |
180 | |
181 Defining Variables | |
182 ================== | |
183 | |
184 Variables not defined in a site shell script can be set in the | |
185 environment passed to `configure'. However, some packages may run | |
186 configure again during the build, and the customized values of these | |
187 variables may be lost. In order to avoid this problem, you should set | |
188 them in the `configure' command line, using `VAR=value'. For example: | |
189 | |
190 ./configure CC=/usr/local2/bin/gcc | |
191 | |
192 will cause the specified gcc to be used as the C compiler (unless it is | |
193 overridden in the site shell script). | |
194 | |
195 `configure' Invocation | |
196 ====================== | |
197 | |
198 `configure' recognizes the following options to control how it operates. | |
199 | |
200 `--help' | |
201 `-h' | |
202 Print a summary of the options to `configure', and exit. | |
203 | |
204 `--version' | |
205 `-V' | |
206 Print the version of Autoconf used to generate the `configure' | |
207 script, and exit. | |
208 | |
209 `--cache-file=FILE' | |
210 Enable the cache: use and save the results of the tests in FILE, | |
211 traditionally `config.cache'. FILE defaults to `/dev/null' to | |
212 disable caching. | |
213 | |
214 `--config-cache' | |
215 `-C' | |
216 Alias for `--cache-file=config.cache'. | |
217 | |
218 `--quiet' | |
219 `--silent' | |
220 `-q' | |
221 Do not print messages saying which checks are being made. To | |
222 suppress all normal output, redirect it to `/dev/null' (any error | |
223 messages will still be shown). | |
224 | |
225 `--srcdir=DIR' | |
226 Look for the package's source code in directory DIR. Usually | |
227 `configure' can determine that directory automatically. | |
228 | |
229 `configure' also accepts some other, not widely useful, options. Run | |
230 `configure --help' for more details. | |
