6 The `configure' shell script attempts to guess correct values for
551433a01cab initial coding
carl
parents:
diff changeset
7 various system-dependent variables used during compilation. It uses
551433a01cab initial coding
carl
parents:
diff changeset
8 those values to create a `Makefile' in each directory of the package.
551433a01cab initial coding
carl
parents:
diff changeset
9 It may also create one or more `.h' files containing system-dependent
551433a01cab initial coding
carl
parents:
diff changeset
10 definitions. Finally, it creates a shell script `config.status' that
551433a01cab initial coding
carl
parents:
diff changeset
11 you can run in the future to recreate the current configuration, a file
551433a01cab initial coding
carl
parents:
diff changeset
12 `config.cache' that saves the results of its tests to speed up
551433a01cab initial coding
carl
parents:
diff changeset
13 reconfiguring, and a file `config.log' containing compiler output
551433a01cab initial coding
carl
parents:
diff changeset
14 (useful mainly for debugging `configure').

16 If you need to do unusual things to compile the package, please try
551433a01cab initial coding
carl
parents:
diff changeset
17 to figure out how `configure' could check whether to do them, and mail
551433a01cab initial coding
carl
parents:
diff changeset
18 diffs or instructions to the address given in the `README' so they can
551433a01cab initial coding
carl
parents:
diff changeset
19 be considered for the next release. If at some point `config.cache'
551433a01cab initial coding
carl
parents:
diff changeset
20 contains results you don't want to keep, you may remove or edit it.
551433a01cab initial coding
carl
parents:
diff changeset
21
551433a01cab initial coding
carl
parents:
diff changeset
22 The file `configure.in' is used to create `configure' by a program
551433a01cab initial coding
carl
parents:
diff changeset
23 called `autoconf'. You only need `configure.in' if you want to change
551433a01cab initial coding
carl
parents:
diff changeset
24 it or regenerate `configure' using a newer version of `autoconf'.
551433a01cab initial coding

26 The simplest way to compile this package is:
551433a01cab initial coding
carl
parents:
diff changeset
27
551433a01cab initial coding
carl
parents:
diff changeset
28 1. `cd' to the directory containing the package's source code and type
551433a01cab initial coding
carl
parents:
diff changeset
29 `./configure' to configure the package for your system. If you're
551433a01cab initial coding
carl
parents:
diff changeset
30 using `csh' on an old version of System V, you might need to type
551433a01cab initial coding
carl
parents:
diff changeset
31 `sh ./configure' instead to prevent `csh' from trying to execute
551433a01cab initial coding
carl
parents:
diff changeset
32 `configure' itself.
551433a01cab initial coding
carl
parents:
diff changeset
33
551433a01cab initial coding
carl
parents:
diff changeset
34 Running `configure' takes a while. While running, it prints some
551433a01cab initial coding
carl
parents:
diff changeset
35 messages telling which features it is checking for.
551433a01cab initial coding
carl
parents:
diff changeset
36
551433a01cab initial coding
carl
parents:
diff changeset
37 2. Type `make' to compile the package.
551433a01cab initial coding
carl
parents:
diff changeset
38
551433a01cab initial coding
carl
parents:
diff changeset
39 3. Type `make install' to install the programs and any data files and
551433a01cab initial coding
carl
parents:
diff changeset
40 documentation.
551433a01cab initial coding
carl
parents:
diff changeset
41
551433a01cab initial coding
carl
parents:
diff changeset
42 4. You can remove the program binaries and object files from the
551433a01cab initial coding
carl
parents:
diff changeset
43 source code directory by typing `make clean'.

45 Compilers and Options
551433a01cab initial coding
carl
parents:
diff changeset
46 =====================
551433a01cab initial coding
carl
parents:
diff changeset
47
551433a01cab initial coding
carl
parents:
diff changeset
48 Some systems require unusual options for compilation or linking that
551433a01cab initial coding
carl
parents:
diff changeset
49 the `configure' script does not know about. You can give `configure'
551433a01cab initial coding
carl
parents:
diff changeset
50 initial values for variables by setting them in the environment. Using
551433a01cab initial coding
carl
parents:
diff changeset
51 a Bourne-compatible shell, you can do that on the command line like
551433a01cab initial coding
carl
parents:
diff changeset
52 this:
551433a01cab initial coding
carl
parents:
diff changeset
53 CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
551433a01cab initial coding
carl
parents:
diff changeset
54
551433a01cab initial coding
carl
parents:
diff changeset
55 Or on systems that have the `env' program, you can do it like this:
551433a01cab initial coding
carl
parents:
diff changeset
56 env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
551433a01cab initial coding

58 Compiling For Multiple Architectures
551433a01cab initial coding
carl
parents:
diff changeset
59 ====================================
551433a01cab initial coding
carl
parents:
diff changeset
60
551433a01cab initial coding
carl
parents:
diff changeset
61 You can compile the package for more than one kind of computer at the
551433a01cab initial coding
carl
parents:
diff changeset
62 same time, by placing the object files for each architecture in their
551433a01cab initial coding
carl
parents:
diff changeset
63 own directory. To do this, you must use a version of `make' that
551433a01cab initial coding
carl
parents:
diff changeset
64 supports the `VPATH' variable, such as GNU `make'. `cd' to the
551433a01cab initial coding
carl
parents:
diff changeset
65 directory where you want the object files and executables to go and run
551433a01cab initial coding
carl
parents:
diff changeset
66 the `configure' script. `configure' automatically checks for the
551433a01cab initial coding
carl
parents:
diff changeset
67 source code in the directory that `configure' is in and in `..'.
551433a01cab initial coding
carl
parents:
diff changeset
68
551433a01cab initial coding
carl
parents:
diff changeset
69 If you have to use a `make' that does not supports the `VPATH'
551433a01cab initial coding
carl
parents:
diff changeset
70 variable, you have to compile the package for one architecture at a time
551433a01cab initial coding
carl
parents:
diff changeset
71 in the source code directory. After you have installed the package for
551433a01cab initial coding
carl
parents:
diff changeset
72 one architecture, use `make distclean' before reconfiguring for another
551433a01cab initial coding
carl
parents:
diff changeset
73 architecture.

75 Installation Names

76 ==================
551433a01cab initial coding
carl
parents:
diff changeset
77
551433a01cab initial coding
carl
parents:
diff changeset
78 By default, `make install' will install the package's files in
551433a01cab initial coding
carl
parents:
diff changeset
79 `/usr/local/bin', `/usr/local/man', etc. You can specify an
551433a01cab initial coding
carl
parents:
diff changeset
80 installation prefix other than `/usr/local' by giving `configure' the
551433a01cab initial coding
carl
parents:
diff changeset
81 option `--prefix=PATH'.
551433a01cab initial coding
carl
parents:
diff changeset
82
551433a01cab initial coding
carl
parents:
diff changeset
83 You can specify separate installation prefixes for
551433a01cab initial coding
carl
parents:
diff changeset
84 architecture-specific files and architecture-independent files. If you
551433a01cab initial coding
carl
parents:
diff changeset
85 give `configure' the option `--exec-prefix=PATH', the package will use
551433a01cab initial coding
carl
parents:
diff changeset
86 PATH as the prefix for installing programs and libraries.
551433a01cab initial coding
carl
parents:
diff changeset
87 Documentation and other data files will still use the regular prefix.
551433a01cab initial coding
carl
parents:
diff changeset
88
551433a01cab initial coding
carl
parents:
diff changeset
89 If the package supports it, you can cause programs to be installed
551433a01cab initial coding
carl
parents:
diff changeset
90 with an extra prefix or suffix on their names by giving `configure' the
551433a01cab initial coding
carl
parents:
diff changeset
91 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

93 Optional Features
551433a01cab initial coding
carl
parents:
diff changeset
94 =================
551433a01cab initial coding
carl
parents:
diff changeset
95
551433a01cab initial coding
carl
parents:
diff changeset
96 Some packages pay attention to `--enable-FEATURE' options to
551433a01cab initial coding
carl
parents:
diff changeset
97 `configure', where FEATURE indicates an optional part of the package.
551433a01cab initial coding
carl
parents:
diff changeset
98 They may also pay attention to `--with-PACKAGE' options, where PACKAGE
551433a01cab initial coding
carl
parents:
diff changeset
99 is something like `gnu-as' or `x' (for the X Window System). The
551433a01cab initial coding
carl
parents:
diff changeset
100 `README' should mention any `--enable-' and `--with-' options that the
551433a01cab initial coding
carl
parents:
diff changeset
101 package recognizes.
551433a01cab initial coding
carl
parents:
diff changeset
102
551433a01cab initial coding
carl
parents:
diff changeset
103 For packages that use the X Window System, `configure' can usually
551433a01cab initial coding
carl
parents:
diff changeset
104 find the X include and library files automatically, but if it doesn't,
551433a01cab initial coding
carl
parents:
diff changeset
105 you can use the `configure' options `--x-includes=DIR' and
551433a01cab initial coding
carl
parents:
diff changeset
106 `--x-libraries=DIR' to specify their locations.

108 Specifying the System Type
551433a01cab initial coding
carl
parents:
diff changeset
109 ==========================
551433a01cab initial coding
carl
parents:
diff changeset
110
551433a01cab initial coding
carl
parents:
diff changeset
111 There may be some features `configure' can not figure out
551433a01cab initial coding
carl
parents:
diff changeset
112 automatically, but needs to determine by the type of host the package
551433a01cab initial coding
carl
parents:
diff changeset
113 will run on. Usually `configure' can figure that out, but if it prints
551433a01cab initial coding
carl
parents:
diff changeset
114 a message saying it can not guess the host type, give it the
551433a01cab initial coding
carl
parents:
diff changeset
115 `--host=TYPE' option. TYPE can either be a short name for the system
551433a01cab initial coding
carl
parents:
diff changeset
116 type, such as `sun4', or a canonical name with three fields:
551433a01cab initial coding
carl
parents:
diff changeset
117 CPU-COMPANY-SYSTEM
551433a01cab initial coding
carl
parents:
diff changeset
118
551433a01cab initial coding
carl
parents:
diff changeset
119 See the file `config.sub' for the possible values of each field. If
551433a01cab initial coding
carl
parents:
diff changeset
120 `config.sub' isn't included in this package, then this package doesn't
551433a01cab initial coding
carl

551433a01cab initial coding
carl
parents:
diff changeset
123 If you are building compiler tools for cross-compiling, you can also
551433a01cab initial coding
carl
parents:
diff changeset
124 use the `--target=TYPE' option to select the type of system they will
551433a01cab initial coding
carl
parents:
diff changeset
125 produce code for and the `--build=TYPE' option to select the type of
551433a01cab initial coding
carl
parents:
diff changeset
126 system on which you are compiling the package.

carl
parents:
diff changeset
130
551433a01cab initial coding
carl
parents:
diff changeset
131 If you want to set default values for `configure' scripts to share,
551433a01cab initial coding
carl
parents:
diff changeset
132 you can create a site shell script called `config.site' that gives
551433a01cab initial coding
carl
parents:
diff changeset
133 default values for variables like `CC', `cache_file', and `prefix'.
551433a01cab initial coding
carl
parents:
diff changeset
134 `configure' looks for `PREFIX/share/config.site' if it exists, then
551433a01cab initial coding
carl
parents:
diff changeset
135 `PREFIX/etc/config.site' if it exists. Or, you can set the
551433a01cab initial coding
carl
parents:
diff changeset
136 `CONFIG_SITE' environment variable to the location of the site script.
551433a01cab initial coding
carl

parents:
diff changeset
146 Use and save the results of the tests in FILE instead of
551433a01cab initial coding
carl
parents:
diff changeset
147 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
551433a01cab initial coding

158 `--srcdir=DIR'
551433a01cab initial coding
carl
parents:
diff changeset
159 Look for the package's source code in directory DIR. Usually
551433a01cab initial coding
carl
