1 This is a generic INSTALL file for utilities distributions.
2 If this package does not come with, e.g., installable documentation or
3 data files, please ignore the references to them below.
5 To compile this package:
7 1. Configure the package for your system. In the directory that this
8 file is in, type `./configure'. If you're using `csh' on an old
9 version of System V, you might need to type `sh configure' instead to
10 prevent `csh' from trying to execute `configure' itself.
12 The `configure' shell script attempts to guess correct values for
13 various system-dependent variables used during compilation, and
14 creates the Makefile(s) (one in each subdirectory of the source
15 directory). In some packages it creates a C header file containing
16 system-dependent definitions. It also creates a file `config.status'
17 that you can run in the future to recreate the current configuration.
19 Running `configure' takes a minute or two. While it is running, it
20 prints some messages that tell what it is doing. If you don't want to
21 see the messages, run `configure' with its standard output redirected
22 to `/dev/null'; for example, `./configure >/dev/null'.
24 To compile the package in a different directory from the one
25 containing the source code, you must use a version of make that
26 supports the VPATH variable, such as GNU make. `cd' to the directory
27 where you want the object files and executables to go and run
28 `configure'. `configure' automatically checks for the source code in
29 the directory that `configure' is in and in `..'. If for some reason
30 `configure' is not in the source code directory that you are
31 configuring, then it will report that it can't find the source code.
32 In that case, run `configure' with the option `--srcdir=DIR', where
33 DIR is the directory that contains the source code.
35 By default, `make install' will install the package's files in
36 /usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
37 an installation prefix other than /usr/local by giving `configure' the
38 option `--prefix=PATH'. Alternately, you can do so by giving a value
39 for the `prefix' variable when you run `make', e.g.,
42 You can specify separate installation prefixes for
43 architecture-specific files and architecture-independent files. If
44 you give `configure' the option `--exec_prefix=PATH' or set the
45 `make' variable `exec_prefix' to PATH, the package will use PATH as
46 the prefix for installing programs and libraries. Data files and
47 documentation will still use the regular prefix. Normally, all files
48 are installed using the regular prefix.
50 You can tell `configure' to figure out the configuration for your
51 system, and record it in `config.status', without actually configuring
52 the package (creating `Makefile's and perhaps a configuration header
53 file). To do this, give `configure' the `--no-create' option. Later,
54 you can run `./config.status' to actually configure the package. This
55 option is useful mainly in `Makefile' rules for updating `config.status'
56 and `Makefile'. You can also give `config.status' the `--recheck'
57 option, which makes it re-run `configure' with the same arguments you
58 used before. This is useful if you change `configure'.
60 `configure' ignores any other arguments that you give it.
62 If your system requires unusual options for compilation or linking
63 that `configure' doesn't know about, you can give `configure' initial
64 values for some variables by setting them in the environment. In
65 Bourne-compatible shells, you can do that on the command line like
67 CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
69 The `make' variables that you might want to override with environment
70 variables when running `configure' are:
72 (For these variables, any value given in the environment overrides the
73 value that `configure' would choose:)
74 CC C compiler program.
75 Default is `cc', or `gcc' if `gcc' is in your PATH.
76 INSTALL Program to use to install files.
77 Default is `install' if you have it, `cp' otherwise.
79 (For these variables, any value given in the environment is added to
80 the value that `configure' chooses:)
81 DEFS Configuration options, in the form `-Dfoo -Dbar ...'
82 LIBS Libraries to link with, in the form `-lfoo -lbar ...'
84 If you need to do unusual things to compile the package, we encourage
85 you to figure out how `configure' could check whether to do them, and
86 mail diffs or instructions to the address given in the README so we
87 can include them in the next release.
89 2. Type `make' to compile the package. If you want, you can override
90 the `make' variables CFLAGS and LDFLAGS like this:
92 make CFLAGS=-O2 LDFLAGS=-s
94 3. If the package comes with self-tests and you want to run them,
95 type `make check'. If you're not sure whether there are any, try it;
96 if `make' responds with something like
97 make: *** No way to make target `check'. Stop.
98 then the package does not come with self-tests.
100 4. Type `make install' to install programs, data files, and
103 5. You can remove the program binaries and object files from the
104 source directory by typing `make clean'. To also remove the
105 Makefile(s), the header file containing system-dependent definitions
106 (if the package uses one), and `config.status' (all the files that
107 `configure' created), type `make distclean'.
109 The file `configure.in' is used as a template to create `configure' by
110 a program called `autoconf'. You will only need it if you want to
111 regenerate `configure' using a newer version of `autoconf'.
