11 Basic Installation
12 ==================
13
14 Briefly, the shell commands `./configure; make; make install' should
15 configure, build, and install this package. The following
16 more-detailed instructions are generic; see the `README' file for
17 instructions specific to this package. Some packages provide this
18 `INSTALL' file but do not implement all of the features documented
19 below. The lack of an optional feature in a given package is not
20 necessarily a bug. More recommendations for GNU packages can be found
21 in *note Makefile Conventions: (standards)Makefile Conventions.
22
23 The `configure' shell script attempts to guess correct values for
24 various system-dependent variables used during compilation. It uses
25 those values to create a `Makefile' in each directory of the package.
26 It may also create one or more `.h' files containing system-dependent
27 definitions. Finally, it creates a shell script `config.status' that
28 you can run in the future to recreate the current configuration, and a
29 file `config.log' containing compiler output (useful mainly for
30 debugging `configure').
31
32 It can also use an optional file (typically called `config.cache'
33 and enabled with `--cache-file=config.cache' or simply `-C') that saves
34 the results of its tests to speed up reconfiguring. Caching is
35 disabled by default to prevent problems with accidental use of stale
36 cache files.
37
38 If you need to do unusual things to compile the package, please try
39 to figure out how `configure' could check whether to do them, and mail
40 diffs or instructions to the address given in the `README' so they can
41 be considered for the next release. If you are using the cache, and at
42 some point `config.cache' contains results you don't want to keep, you
43 may remove or edit it.
44
45 The file `configure.ac' (or `configure.in') is used to create
46 `configure' by a program called `autoconf'. You need `configure.ac' if
47 you want to change it or regenerate `configure' using a newer version
48 of `autoconf'.
49
50 The simplest way to compile this package is:
51
52 1. `cd' to the directory containing the package's source code and type
53 `./configure' to configure the package for your system.
54
55 Running `configure' might take a while. While running, it prints
56 some messages telling which features it is checking for.
57
58 2. Type `make' to compile the package.
59
60 3. Optionally, type `make check' to run any self-tests that come with
61 the package, generally using the just-built uninstalled binaries.
62
63 4. Type `make install' to install the programs and any data files and
64 documentation. When installing into a prefix owned by root, it is
65 recommended that the package be configured and built as a regular
66 user, and only the `make install' phase executed with root
67 privileges.
68
69 5. Optionally, type `make installcheck' to repeat any self-tests, but
70 this time using the binaries in their final installed location.
71 This target does not install anything. Running this target as a
72 regular user, particularly if the prior `make install' required
73 root privileges, verifies that the installation completed
74 correctly.
75
76 6. You can remove the program binaries and object files from the
77 source code directory by typing `make clean'. To also remove the
78 files that `configure' created (so you can compile the package for
79 a different kind of computer), type `make distclean'. There is
80 also a `make maintainer-clean' target, but that is intended mainly
81 for the package's developers. If you use it, you may have to get
82 all sorts of other programs in order to regenerate files that came
83 with the distribution.
84
85 7. Often, you can also type `make uninstall' to remove the installed
86 files again. In practice, not all packages have tested that
87 uninstallation works correctly, even though it is required by the
88 GNU Coding Standards.
89
90 8. Some packages, particularly those that use Automake, provide `make
91 distcheck', which can by used by developers to test that all other
92 targets like `make install' and `make uninstall' work correctly.
93 This target is generally not run by end users.
94
95 Compilers and Options
96 =====================
97
98 Some systems require unusual options for compilation or linking that
99 the `configure' script does not know about. Run `./configure --help'
100 for details on some of the pertinent environment variables.
101
102 You can give `configure' initial values for configuration parameters
103 by setting variables in the command line or in the environment. Here
104 is an example:
105
106 ./configure CC=c99 CFLAGS=-g LIBS=-lposix
107
108 *Note Defining Variables::, for more details.
109
110 Compiling For Multiple Architectures
111 ====================================
112
113 You can compile the package for more than one kind of computer at the
114 same time, by placing the object files for each architecture in their
115 own directory. To do this, you can use GNU `make'. `cd' to the
116 directory where you want the object files and executables to go and run
117 the `configure' script. `configure' automatically checks for the
118 source code in the directory that `configure' is in and in `..'. This
119 is known as a "VPATH" build.
120
121 With a non-GNU `make', it is safer to compile the package for one
122 architecture at a time in the source code directory. After you have
123 installed the package for one architecture, use `make distclean' before
124 reconfiguring for another architecture.
125
126 On MacOS X 10.5 and later systems, you can create libraries and
127 executables that work on multiple system types--known as "fat" or
128 "universal" binaries--by specifying multiple `-arch' options to the
129 compiler but only a single `-arch' option to the preprocessor. Like
130 this:
131
132 ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
133 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
134 CPP="gcc -E" CXXCPP="g++ -E"
135
136 This is not guaranteed to produce working output in all cases, you
137 may have to build one architecture at a time and combine the results
138 using the `lipo' tool if you have problems.
139
140 Installation Names
141 ==================
142
143 By default, `make install' installs the package's commands under
144 `/usr/local/bin', include files under `/usr/local/include', etc. You
145 can specify an installation prefix other than `/usr/local' by giving
146 `configure' the option `--prefix=PREFIX', where PREFIX must be an
147 absolute file name.
148
149 You can specify separate installation prefixes for
150 architecture-specific files and architecture-independent files. If you
151 pass the option `--exec-prefix=PREFIX' to `configure', the package uses
152 PREFIX as the prefix for installing programs and libraries.
153 Documentation and other data files still use the regular prefix.
154
155 In addition, if you use an unusual directory layout you can give
156 options like `--bindir=DIR' to specify different values for particular
157 kinds of files. Run `configure --help' for a list of the directories
158 you can set and what kinds of files go in them. In general, the
159 default for these options is expressed in terms of `${prefix}', so that
160 specifying just `--prefix' will affect all of the other directory
161 specifications that were not explicitly provided.
162
163 The most portable way to affect installation locations is to pass the
164 correct locations to `configure'; however, many packages provide one or
165 both of the following shortcuts of passing variable assignments to the
166 `make install' command line to change installation locations without
167 having to reconfigure or recompile.
168
169 The first method involves providing an override variable for each
170 affected directory. For example, `make install
171 prefix=/alternate/directory' will choose an alternate location for all
172 directory configuration variables that were expressed in terms of
173 `${prefix}'. Any directories that were specified during `configure',
174 but not in terms of `${prefix}', must each be overridden at install
175 time for the entire installation to be relocated. The approach of
176 makefile variable overrides for each directory variable is required by
177 the GNU Coding Standards, and ideally causes no recompilation.
178 However, some platforms have known limitations with the semantics of
179 shared libraries that end up requiring recompilation when using this
180 method, particularly noticeable in packages that use GNU Libtool.
181
182 The second method involves providing the `DESTDIR' variable. For
183 example, `make install DESTDIR=/alternate/directory' will prepend
184 `/alternate/directory' before all installation names. The approach of
185 `DESTDIR' overrides is not required by the GNU Coding Standards, and
186 does not work on platforms that have drive letters. On the other hand,
187 it does better at avoiding recompilation issues, and works well even
188 when some directory options were not specified in terms of `${prefix}'
189 at `configure' time.
190
191 Optional Features
192 =================
193
194 If the package supports it, you can cause programs to be installed
195 with an extra prefix or suffix on their names by giving `configure' the
196 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
197
198 Some packages pay attention to `--enable-FEATURE' options to
199 `configure', where FEATURE indicates an optional part of the package.
200 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
201 is something like `gnu-as' or `x' (for the X Window System). The
202 `README' should mention any `--enable-' and `--with-' options that the
203 package recognizes.
204
205 For packages that use the X Window System, `configure' can usually
206 find the X include and library files automatically, but if it doesn't,
207 you can use the `configure' options `--x-includes=DIR' and
208 `--x-libraries=DIR' to specify their locations.
209
210 Some packages offer the ability to configure how verbose the
211 execution of `make' will be. For these packages, running `./configure
212 --enable-silent-rules' sets the default to minimal output, which can be
213 overridden with `make V=1'; while running `./configure
214 --disable-silent-rules' sets the default to verbose, which can be
215 overridden with `make V=0'.
216
217 Particular systems
218 ==================
219
220 On HP-UX, the default C compiler is not ANSI C compatible. If GNU
221 CC is not installed, it is recommended to use the following options in
222 order to use an ANSI C compiler:
223
224 ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
225
226 and if that doesn't work, install pre-built binaries of GCC for HP-UX.
227
228 HP-UX `make' updates targets which have the same time stamps as
229 their prerequisites, which makes it generally unusable when shipped
230 generated files such as `configure' are involved. Use GNU `make'
231 instead.
232
233 On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
234 parse its `<wchar.h>' header file. The option `-nodtk' can be used as
235 a workaround. If GNU CC is not installed, it is therefore recommended
236 to try
237
238 ./configure CC="cc"
239
240 and if that doesn't work, try
241
242 ./configure CC="cc -nodtk"
243
244 On Solaris, don't put `/usr/ucb' early in your `PATH'. This
245 directory contains several dysfunctional programs; working variants of
246 these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
247 in your `PATH', put it _after_ `/usr/bin'.
248
249 On Haiku, software installed for all users goes in `/boot/common',
250 not `/usr/local'. It is recommended to use the following options:
251
252 ./configure --prefix=/boot/common
253
254 Specifying the System Type
255 ==========================
256
257 There may be some features `configure' cannot figure out
258 automatically, but needs to determine by the type of machine the package
259 will run on. Usually, assuming the package is built to be run on the
260 _same_ architectures, `configure' can figure that out, but if it prints
261 a message saying it cannot guess the machine type, give it the
262 `--build=TYPE' option. TYPE can either be a short name for the system
263 type, such as `sun4', or a canonical name which has the form:
264
265 CPU-COMPANY-SYSTEM
266
267 where SYSTEM can have one of these forms:
268
269 OS
270 KERNEL-OS
271
272 See the file `config.sub' for the possible values of each field. If
273 `config.sub' isn't included in this package, then this package doesn't
274 need to know the machine type.
275
276 If you are _building_ compiler tools for cross-compiling, you should
277 use the option `--target=TYPE' to select the type of system they will
278 produce code for.
279
280 If you want to _use_ a cross compiler, that generates code for a
281 platform different from the build platform, you should specify the
282 "host" platform (i.e., that on which the generated programs will
283 eventually be run) with `--host=TYPE'.
284
285 Sharing Defaults
286 ================
287
288 If you want to set default values for `configure' scripts to share,
289 you can create a site shell script called `config.site' that gives
290 default values for variables like `CC', `cache_file', and `prefix'.
291 `configure' looks for `PREFIX/share/config.site' if it exists, then
292 `PREFIX/etc/config.site' if it exists. Or, you can set the
293 `CONFIG_SITE' environment variable to the location of the site script.
294 A warning: not all `configure' scripts look for a site script.
295
296 Defining Variables
297 ==================
298
299 Variables not defined in a site shell script can be set in the
300 environment passed to `configure'. However, some packages may run
301 configure again during the build, and the customized values of these
302 variables may be lost. In order to avoid this problem, you should set
303 them in the `configure' command line, using `VAR=value'. For example:
304
305 ./configure CC=/usr/local2/bin/gcc
306
307 causes the specified `gcc' to be used as the C compiler (unless it is
308 overridden in the site shell script).
309
310 Unfortunately, this technique does not work for `CONFIG_SHELL' due to
311 an Autoconf limitation. Until the limitation is lifted, you can use
312 this workaround:
313
314 CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
315
316 `configure' Invocation
317 ======================
318
319 `configure' recognizes the following options to control how it
320 operates.
321
322 `--help'
323 `-h'
324 Print a summary of all of the options to `configure', and exit.
325
326 `--help=short'
327 `--help=recursive'
328 Print a summary of the options unique to this package's
329 `configure', and exit. The `short' variant lists options used
330 only in the top level, while the `recursive' variant lists options
331 also present in any nested packages.
332
333 `--version'
334 `-V'
335 Print the version of Autoconf used to generate the `configure'
336 script, and exit.
337
338 `--cache-file=FILE'
339 Enable the cache: use and save the results of the tests in FILE,
340 traditionally `config.cache'. FILE defaults to `/dev/null' to
341 disable caching.
342
343 `--config-cache'
344 `-C'
345 Alias for `--cache-file=config.cache'.
346
347 `--quiet'
348 `--silent'
349 `-q'
350 Do not print messages saying which checks are being made. To
351 suppress all normal output, redirect it to `/dev/null' (any error
352 messages will still be shown).
353
354 `--srcdir=DIR'
355 Look for the package's source code in directory DIR. Usually
356 `configure' can determine that directory automatically.
357
358 `--prefix=DIR'
359 Use DIR as the installation prefix. *note Installation Names::
360 for more details, including other options available for fine-tuning
361 the installation locations.
362
363 `--no-create'
364 `-n'
365 Run the configure checks, but stop before creating any output
366 files.
367
368 `configure' also accepts some other, not widely useful, options. Run
369 `configure --help' for more details.

66 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
67 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
68 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
69 #
70 # Of course, Automake must honor this variable whenever it calls a
71 # tool from the auxiliary directory. The problem is that $srcdir (and
72 # therefore $ac_aux_dir as well) can be either absolute or relative,
73 # depending on how configure is run. This is pretty annoying, since
74 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
75 # source directory, any form will work fine, but in subdirectories a
76 # relative path needs to be adjusted first.
77 #
78 # $ac_aux_dir/missing
79 # fails when called from a subdirectory if $ac_aux_dir is relative
80 # $top_srcdir/$ac_aux_dir/missing
81 # fails if $ac_aux_dir is absolute,
82 # fails when called from a subdirectory in a VPATH build with
83 # a relative $ac_aux_dir
84 #
85 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
86 # are both prefixed by $srcdir. In an in-source build this is usually
87 # harmless because $srcdir is '.', but things will broke when you
88 # start a VPATH build or use an absolute $srcdir.
89 #
90 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
91 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
92 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
93 # and then we would define $MISSING as
94 # MISSING="\${SHELL} $am_aux_dir/missing"
95 # This will work as long as MISSING is not called from configure, because
96 # unfortunately $(top_srcdir) has no meaning in configure.
97 # However there are other variables, like CC, which are often used in
98 # configure, and could therefore not use this "fixed" $ac_aux_dir.
99 #
100 # Another solution, used here, is to always expand $ac_aux_dir to an
101 # absolute PATH. The drawback is that using absolute paths prevent a
102 # configured tree to be moved without reconfiguration.
