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