12 Dasher makes use of the GNU autotools system (automake, autoconf
13 etc.), so users familiar with these probably know most of the

19 The `configure' shell script attempts to guess correct values for
20 various system-dependent variables used during compilation. It uses
21 those values to create a `Makefile' in each directory of the package.
22 It may also create one or more `.h' files containing system-dependent
23 definitions. Finally, it creates a shell script `config.status' that
24 you can run in the future to recreate the current configuration, and a
25 file `config.log' containing compiler output (useful mainly for
26 debugging `configure').
28 It can also use an optional file (typically called `config.cache'
29 and enabled with `--cache-file=config.cache' or simply `-C') that saves
30 the results of its tests to speed up reconfiguring. (Caching is
31 disabled by default to prevent problems with accidental use of stale
34 If you need to do unusual things to compile the package, please try
35 to figure out how `configure' could check whether to do them, and mail
36 diffs or instructions to the address given in the `README' so they can
37 be considered for the next release. If you are using the cache, and at
38 some point `config.cache' contains results you don't want to keep, you
39 may remove or edit it.
41 The file `configure.ac' (or `configure.in') is used to create
42 `configure' by a program called `autoconf'. You only need
43 `configure.ac' if you want to change it or regenerate `configure' using
44 a newer version of `autoconf'.
46 The simplest way to compile this package is:
48 1. `cd' to the directory containing the package's source code and type
49 `./configure' to configure the package for your system. If you're
50 using `csh' on an old version of System V, you might need to type
51 `sh ./configure' instead to prevent `csh' from trying to execute
54 Running `configure' takes awhile. While running, it prints some
55 messages telling which features it is checking for.
57 2. Type `make' to compile the package.
59 3. Optionally, type `make check' to run any self-tests that come with
62 4. Type `make install' to install the programs and any data files and
65 5. You can remove the program binaries and object files from the
66 source code directory by typing `make clean'. To also remove the
67 files that `configure' created (so you can compile the package for
68 a different kind of computer), type `make distclean'. There is
69 also a `make maintainer-clean' target, but that is intended mainly
70 for the package's developers. If you use it, you may have to get
71 all sorts of other programs in order to regenerate files that came
72 with the distribution.
77 The following options are available for Dasher:
79 --without-gnome Disable features which require the GNOME core
80 libraries (enabled by default).
82 --with-speech Enable GNOME-Speech support (disabled by default).
84 --without-a11y Disable support for GNOME accessibility features
85 (enabled by default). You should probably specify
86 this as well if you're using --without-gnome.
88 The following options include code which is significantly out of
89 date and currently untested. It is likely that these options will not
90 correctly build without modifications to the source code. If you are
91 willing to invest some time in getting these up to date, please let us
94 --with-gpe Build binaries for the GPE palmtop environment.
96 --with-qte Build binaries using the QTE environment.
101 Some systems require unusual options for compilation or linking that
102 the `configure' script does not know about. Run `./configure --help'
103 for details on some of the pertinent environment variables.
105 You can give `configure' initial values for configuration parameters
106 by setting variables in the command line or in the environment. Here
109 ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
111 *Note Defining Variables::, for more details.
113 Compiling For Multiple Architectures
114 ====================================
116 You can compile the package for more than one kind of computer at the
117 same time, by placing the object files for each architecture in their
118 own directory. To do this, you must use a version of `make' that
119 supports the `VPATH' variable, such as GNU `make'. `cd' to the
120 directory where you want the object files and executables to go and run
121 the `configure' script. `configure' automatically checks for the
122 source code in the directory that `configure' is in and in `..'.
124 If you have to use a `make' that does not support the `VPATH'
125 variable, you have to compile the package for one architecture at a
126 time in the source code directory. After you have installed the
127 package for one architecture, use `make distclean' before reconfiguring
128 for another architecture.
133 By default, `make install' will install the package's files in
134 `/usr/local/bin', `/usr/local/man', etc. You can specify an
135 installation prefix other than `/usr/local' by giving `configure' the
136 option `--prefix=PATH'.
138 You can specify separate installation prefixes for
139 architecture-specific files and architecture-independent files. If you
140 give `configure' the option `--exec-prefix=PATH', the package will use
141 PATH as the prefix for installing programs and libraries.
142 Documentation and other data files will still use the regular prefix.
144 In addition, if you use an unusual directory layout you can give
145 options like `--bindir=PATH' to specify different values for particular
146 kinds of files. Run `configure --help' for a list of the directories
147 you can set and what kinds of files go in them.
149 If the package supports it, you can cause programs to be installed
150 with an extra prefix or suffix on their names by giving `configure' the
151 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
156 Some packages pay attention to `--enable-FEATURE' options to
157 `configure', where FEATURE indicates an optional part of the package.
158 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
159 is something like `gnu-as' or `x' (for the X Window System). The
160 `README' should mention any `--enable-' and `--with-' options that the
163 For packages that use the X Window System, `configure' can usually
164 find the X include and library files automatically, but if it doesn't,
165 you can use the `configure' options `--x-includes=DIR' and
166 `--x-libraries=DIR' to specify their locations.
168 Specifying the System Type
169 ==========================
171 There may be some features `configure' cannot figure out
172 automatically, but needs to determine by the type of machine the package
173 will run on. Usually, assuming the package is built to be run on the
174 _same_ architectures, `configure' can figure that out, but if it prints
175 a message saying it cannot guess the machine type, give it the
176 `--build=TYPE' option. TYPE can either be a short name for the system
177 type, such as `sun4', or a canonical name which has the form:
181 where SYSTEM can have one of these forms:
185 See the file `config.sub' for the possible values of each field. If
186 `config.sub' isn't included in this package, then this package doesn't
187 need to know the machine type.
189 If you are _building_ compiler tools for cross-compiling, you should
190 use the `--target=TYPE' option to select the type of system they will
193 If you want to _use_ a cross compiler, that generates code for a
194 platform different from the build platform, you should specify the
195 "host" platform (i.e., that on which the generated programs will
196 eventually be run) with `--host=TYPE'.
201 If you want to set default values for `configure' scripts to share,
202 you can create a site shell script called `config.site' that gives
203 default values for variables like `CC', `cache_file', and `prefix'.
204 `configure' looks for `PREFIX/share/config.site' if it exists, then
205 `PREFIX/etc/config.site' if it exists. Or, you can set the
206 `CONFIG_SITE' environment variable to the location of the site script.
207 A warning: not all `configure' scripts look for a site script.
212 Variables not defined in a site shell script can be set in the
213 environment passed to `configure'. However, some packages may run
214 configure again during the build, and the customized values of these
215 variables may be lost. In order to avoid this problem, you should set
216 them in the `configure' command line, using `VAR=value'. For example:
218 ./configure CC=/usr/local2/bin/gcc
220 will cause the specified gcc to be used as the C compiler (unless it is
221 overridden in the site shell script).
223 `configure' Invocation
224 ======================
226 `configure' recognizes the following options to control how it
231 Print a summary of the options to `configure', and exit.
235 Print the version of Autoconf used to generate the `configure'
239 Enable the cache: use and save the results of the tests in FILE,
240 traditionally `config.cache'. FILE defaults to `/dev/null' to
245 Alias for `--cache-file=config.cache'.
250 Do not print messages saying which checks are being made. To
251 suppress all normal output, redirect it to `/dev/null' (any error
252 messages will still be shown).
255 Look for the package's source code in directory DIR. Usually
256 `configure' can determine that directory automatically.
258 `configure' also accepts some other, not widely useful, options. Run
259 `configure --help' for more details.
