1.1 misho 1: 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: 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:
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: 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:
22: 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:
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: 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:
64: 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:
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: 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:
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: 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: CPU-COMPANY-SYSTEM
132:
133: See the file `config.sub' for the possible values of each field. If
134: `config.sub' isn't included in this package, then this package doesn't
135: need to know the host type.
136:
137: If you are building compiler tools for cross-compiling, you can also
138: use the `--target=TYPE' option to select the type of system they will
139: produce code for and the `--build=TYPE' option to select the type of
140: system on which you are compiling the package.
141:
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: Operation Controls
154: ==================
155:
156: `configure' recognizes the following options to control how it
157: operates.
158:
159: `--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: `--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: `--version'
179: Print the version of Autoconf used to generate the `configure'
180: script, and exit.
181:
182: `configure' also accepts some other, not widely useful, options.
