1 schoenebeck 9 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 a while. 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. Type `make install' to install the programs and any data files and
40     documentation.
41    
42     4. You can remove the program binaries and object files from the
43     source code directory by typing `make clean'.
44    
45     Compilers and Options
46     =====================
47    
48     Some systems require unusual options for compilation or linking that
49     the `configure' script does not know about. You can give `configure'
50     initial values for variables by setting them in the environment. Using
51     a Bourne-compatible shell, you can do that on the command line like
52     this:
53     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
54    
55     Or on systems that have the `env' program, you can do it like this:
56     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
57    
58     Compiling For Multiple Architectures
59     ====================================
60    
61     You can compile the package for more than one kind of computer at the
62     same time, by placing the object files for each architecture in their
63     own directory. To do this, you must use a version of `make' that
64     supports the `VPATH' variable, such as GNU `make'. `cd' to the
65     directory where you want the object files and executables to go and run
66     the `configure' script. `configure' automatically checks for the
67     source code in the directory that `configure' is in and in `..'.
68    
69     If you have to use a `make' that does not supports the `VPATH'
70     variable, you have to compile the package for one architecture at a time
71     in the source code directory. After you have installed the package for
72     one architecture, use `make distclean' before reconfiguring for another
73     architecture.
74    
75     Installation Names
76     ==================
77    
78     By default, `make install' will install the package's files in
79     `/usr/local/bin', `/usr/local/man', etc. You can specify an
80     installation prefix other than `/usr/local' by giving `configure' the
81     option `--prefix=PATH'.
82    
83     You can specify separate installation prefixes for
84     architecture-specific files and architecture-independent files. If you
85     give `configure' the option `--exec-prefix=PATH', the package will use
86     PATH as the prefix for installing programs and libraries.
87     Documentation and other data files will still use the regular prefix.
88    
89     If the package supports it, you can cause programs to be installed
90     with an extra prefix or suffix on their names by giving `configure' the
91     option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
92    
93     Optional Features
94     =================
95    
96     Some packages pay attention to `--enable-FEATURE' options to
97     `configure', where FEATURE indicates an optional part of the package.
98     They may also pay attention to `--with-PACKAGE' options, where PACKAGE
99     is something like `gnu-as' or `x' (for the X Window System). The
100     `README' should mention any `--enable-' and `--with-' options that the
101     package recognizes.
102    
103     For packages that use the X Window System, `configure' can usually
104     find the X include and library files automatically, but if it doesn't,
105     you can use the `configure' options `--x-includes=DIR' and
106     `--x-libraries=DIR' to specify their locations.
107    
108     Specifying the System Type
109     ==========================
110    
111     There may be some features `configure' can not figure out
112     automatically, but needs to determine by the type of host the package
113     will run on. Usually `configure' can figure that out, but if it prints
114     a message saying it can not guess the host type, give it the
115     `--host=TYPE' option. TYPE can either be a short name for the system
116     type, such as `sun4', or a canonical name with three fields:
117     CPU-COMPANY-SYSTEM
118    
119     See the file `config.sub' for the possible values of each field. If
120     `config.sub' isn't included in this package, then this package doesn't
121     need to know the host type.
122    
123     If you are building compiler tools for cross-compiling, you can also
124     use the `--target=TYPE' option to select the type of system they will
125     produce code for and the `--build=TYPE' option to select the type of
126     system on which you are compiling the package.
127    
128     Sharing Defaults
129     ================
130    
131     If you want to set default values for `configure' scripts to share,
132     you can create a site shell script called `config.site' that gives
133     default values for variables like `CC', `cache_file', and `prefix'.
134     `configure' looks for `PREFIX/share/config.site' if it exists, then
135     `PREFIX/etc/config.site' if it exists. Or, you can set the
136     `CONFIG_SITE' environment variable to the location of the site script.
137     A warning: not all `configure' scripts look for a site script.
138    
139     Operation Controls
140     ==================
141    
142     `configure' recognizes the following options to control how it
143     operates.
144    
145     `--cache-file=FILE'
146     Use and save the results of the tests in FILE instead of
147     `./config.cache'. Set FILE to `/dev/null' to disable caching, for
148     debugging `configure'.
149    
150     `--help'
151     Print a summary of the options to `configure', and exit.
152    
153     `--quiet'
154     `--silent'
155     `-q'
156     Do not print messages saying which checks are being made.
157    
158     `--srcdir=DIR'
159     Look for the package's source code in directory DIR. Usually
160     `configure' can determine that directory automatically.
161    
162     `--version'
163     Print the version of Autoconf used to generate the `configure'
164     script, and exit.
165    
166     `configure' also accepts some other, not widely useful, options.
