4 PSPP has the following library dependencies;
6 * The GNU Scientific Library (libgsl), version 1.6 or later.
8 * libplot from GNU plotutils is optional. Without it, the new
9 graphing features will not work. If you do not have it
10 installed, you must run `configure' with --without-libplot.
12 * ncurses and GNU readline are optional. They make for a more pleasant
13 command line interface.
15 PSPP also has the following build dependencies:
19 A few system-specific issues have been noted. These may be PSPP bugs
20 or system bugs; we have not yet been able to track them down precisely:
22 * On Solaris, one or more tests may fail `make check'. We have
23 only seen this reported on Solaris 9 with GCC 3.4.2. Our
24 reporter says that turning off optimization (with -O0) at least
27 * On Mac OS X, GCC 4.0.0 build 4061 has been observed to cause
28 some tests to fail. Later builds should work fine.
30 Finally, a few extra notes:
32 * The Sun WorkShop compiler will not work out of the box in this
33 release. Use GCC instead. We will fix this for the next
36 * GCC 4.x reports an inordinate number of warnings for this
37 release. You may ignore these for now. We will fix these for

59 The `configure' shell script attempts to guess correct values for
60 various system-dependent variables used during compilation. It uses
61 those values to create a `Makefile' in each directory of the package.
62 It may also create one or more `.h' files containing system-dependent
63 definitions. Finally, it creates a shell script `config.status' that
64 you can run in the future to recreate the current configuration, and a
65 file `config.log' containing compiler output (useful mainly for
66 debugging `configure').
68 It can also use an optional file (typically called `config.cache'
69 and enabled with `--cache-file=config.cache' or simply `-C') that saves
70 the results of its tests to speed up reconfiguring. (Caching is
71 disabled by default to prevent problems with accidental use of stale
74 If you need to do unusual things to compile the package, please try
75 to figure out how `configure' could check whether to do them, and mail
76 diffs or instructions to the address given in the `README' so they can
77 be considered for the next release. If you are using the cache, and at
78 some point `config.cache' contains results you don't want to keep, you
79 may remove or edit it.
81 The file `configure.ac' (or `configure.in') is used to create
82 `configure' by a program called `autoconf'. You only need
83 `configure.ac' if you want to change it or regenerate `configure' using
84 a newer version of `autoconf'.
86 The simplest way to compile this package is:
88 1. `cd' to the directory containing the package's source code and type
89 `./configure' to configure the package for your system. If you're
90 using `csh' on an old version of System V, you might need to type
91 `sh ./configure' instead to prevent `csh' from trying to execute
94 Running `configure' takes awhile. While running, it prints some
95 messages telling which features it is checking for.
97 2. Type `make' to compile the package.
99 3. Optionally, type `make check' to run any self-tests that come with
102 4. Type `make install' to install the programs and any data files and
105 5. You can remove the program binaries and object files from the
106 source code directory by typing `make clean'. To also remove the
107 files that `configure' created (so you can compile the package for
108 a different kind of computer), type `make distclean'. There is
109 also a `make maintainer-clean' target, but that is intended mainly
110 for the package's developers. If you use it, you may have to get
111 all sorts of other programs in order to regenerate files that came
112 with the distribution.
114 Compilers and Options
115 =====================
117 Some systems require unusual options for compilation or linking that
118 the `configure' script does not know about. Run `./configure --help'
119 for details on some of the pertinent environment variables.
121 You can give `configure' initial values for configuration parameters
122 by setting variables in the command line or in the environment. Here
125 ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
127 *Note Defining Variables::, for more details.
129 Compiling For Multiple Architectures
130 ====================================
132 You can compile the package for more than one kind of computer at the
133 same time, by placing the object files for each architecture in their
134 own directory. To do this, you must use a version of `make' that
135 supports the `VPATH' variable, such as GNU `make'. `cd' to the
136 directory where you want the object files and executables to go and run
137 the `configure' script. `configure' automatically checks for the
138 source code in the directory that `configure' is in and in `..'.
140 If you have to use a `make' that does not support the `VPATH'
141 variable, you have to compile the package for one architecture at a
142 time in the source code directory. After you have installed the
143 package for one architecture, use `make distclean' before reconfiguring
144 for another architecture.
149 By default, `make install' will install the package's files in
150 `/usr/local/bin', `/usr/local/man', etc. You can specify an
151 installation prefix other than `/usr/local' by giving `configure' the
152 option `--prefix=PATH'.
154 You can specify separate installation prefixes for
155 architecture-specific files and architecture-independent files. If you
156 give `configure' the option `--exec-prefix=PATH', the package will use
157 PATH as the prefix for installing programs and libraries.
158 Documentation and other data files will still use the regular prefix.
160 In addition, if you use an unusual directory layout you can give
161 options like `--bindir=PATH' to specify different values for particular
162 kinds of files. Run `configure --help' for a list of the directories
163 you can set and what kinds of files go in them.
165 If the package supports it, you can cause programs to be installed
166 with an extra prefix or suffix on their names by giving `configure' the
167 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
172 Some packages pay attention to `--enable-FEATURE' options to
173 `configure', where FEATURE indicates an optional part of the package.
174 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
175 is something like `gnu-as' or `x' (for the X Window System). The
176 `README' should mention any `--enable-' and `--with-' options that the
179 For packages that use the X Window System, `configure' can usually
180 find the X include and library files automatically, but if it doesn't,
181 you can use the `configure' options `--x-includes=DIR' and
182 `--x-libraries=DIR' to specify their locations.
184 Specifying the System Type
185 ==========================
187 There may be some features `configure' cannot figure out
188 automatically, but needs to determine by the type of machine the package
189 will run on. Usually, assuming the package is built to be run on the
190 _same_ architectures, `configure' can figure that out, but if it prints
191 a message saying it cannot guess the machine type, give it the
192 `--build=TYPE' option. TYPE can either be a short name for the system
193 type, such as `sun4', or a canonical name which has the form:
197 where SYSTEM can have one of these forms:
201 See the file `config.sub' for the possible values of each field. If
202 `config.sub' isn't included in this package, then this package doesn't
203 need to know the machine type.
205 If you are _building_ compiler tools for cross-compiling, you should
206 use the `--target=TYPE' option to select the type of system they will
209 If you want to _use_ a cross compiler, that generates code for a
210 platform different from the build platform, you should specify the
211 "host" platform (i.e., that on which the generated programs will
212 eventually be run) with `--host=TYPE'.
217 If you want to set default values for `configure' scripts to share,
218 you can create a site shell script called `config.site' that gives
219 default values for variables like `CC', `cache_file', and `prefix'.
220 `configure' looks for `PREFIX/share/config.site' if it exists, then
221 `PREFIX/etc/config.site' if it exists. Or, you can set the
222 `CONFIG_SITE' environment variable to the location of the site script.
223 A warning: not all `configure' scripts look for a site script.
228 Variables not defined in a site shell script can be set in the
229 environment passed to `configure'. However, some packages may run
230 configure again during the build, and the customized values of these
231 variables may be lost. In order to avoid this problem, you should set
232 them in the `configure' command line, using `VAR=value'. For example:
234 ./configure CC=/usr/local2/bin/gcc
236 will cause the specified gcc to be used as the C compiler (unless it is
237 overridden in the site shell script).
239 `configure' Invocation
240 ======================
242 `configure' recognizes the following options to control how it
247 Print a summary of the options to `configure', and exit.
251 Print the version of Autoconf used to generate the `configure'
255 Enable the cache: use and save the results of the tests in FILE,
256 traditionally `config.cache'. FILE defaults to `/dev/null' to
261 Alias for `--cache-file=config.cache'.
266 Do not print messages saying which checks are being made. To
267 suppress all normal output, redirect it to `/dev/null' (any error
268 messages will still be shown).
271 Look for the package's source code in directory DIR. Usually
272 `configure' can determine that directory automatically.
274 `configure' also accepts some other, not widely useful, options. Run
275 `configure --help' for more details.
