Annotation of embedaddon/sudo/INSTALL.configure, revision 1.1
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. `cd' to the directory where you want the object files
! 73: and executables to go and run the `configure' script. `configure'
! 74: automatically checks for the source code in the directory that `configure'
! 75: is in and in `..'.
! 76:
! 77: Installation Names
! 78: ==================
! 79:
! 80: By default, `make install' will install the package's files in
! 81: `/usr/local/bin', `/usr/local/man', etc. You can specify an
! 82: installation prefix other than `/usr/local' by giving `configure' the
! 83: option `--prefix=PATH'.
! 84:
! 85: You can specify separate installation prefixes for
! 86: architecture-specific files and architecture-independent files. If you
! 87: give `configure' the option `--exec-prefix=PATH', the package will use
! 88: PATH as the prefix for installing programs and libraries.
! 89: Documentation and other data files will still use the regular prefix.
! 90:
! 91: In addition, if you use an unusual directory layout you can give
! 92: options like `--bindir=PATH' to specify different values for particular
! 93: kinds of files. Run `configure --help' for a list of the directories
! 94: you can set and what kinds of files go in them.
! 95:
! 96: If the package supports it, you can cause programs to be installed
! 97: with an extra prefix or suffix on their names by giving `configure' the
! 98: option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
! 99:
! 100: Optional Features
! 101: =================
! 102:
! 103: Some packages pay attention to `--enable-FEATURE' options to
! 104: `configure', where FEATURE indicates an optional part of the package.
! 105: They may also pay attention to `--with-PACKAGE' options, where PACKAGE
! 106: is something like `gnu-as' or `x' (for the X Window System). The
! 107: `README' should mention any `--enable-' and `--with-' options that the
! 108: package recognizes.
! 109:
! 110: For packages that use the X Window System, `configure' can usually
! 111: find the X include and library files automatically, but if it doesn't,
! 112: you can use the `configure' options `--x-includes=DIR' and
! 113: `--x-libraries=DIR' to specify their locations.
! 114:
! 115: Specifying the System Type
! 116: ==========================
! 117:
! 118: There may be some features `configure' can not figure out
! 119: automatically, but needs to determine by the type of host the package
! 120: will run on. Usually `configure' can figure that out, but if it prints
! 121: a message saying it can not guess the host type, give it the
! 122: `--host=TYPE' option. TYPE can either be a short name for the system
! 123: type, such as `sun4', or a canonical name with three fields:
! 124: CPU-COMPANY-SYSTEM
! 125:
! 126: See the file `config.sub' for the possible values of each field. If
! 127: `config.sub' isn't included in this package, then this package doesn't
! 128: need to know the host type.
! 129:
! 130: If you are building compiler tools for cross-compiling, you can also
! 131: use the `--target=TYPE' option to select the type of system they will
! 132: produce code for and the `--build=TYPE' option to select the type of
! 133: system on which you are compiling the package.
! 134:
! 135: Sharing Defaults
! 136: ================
! 137:
! 138: If you want to set default values for `configure' scripts to share,
! 139: you can create a site shell script called `config.site' that gives
! 140: default values for variables like `CC', `cache_file', and `prefix'.
! 141: `configure' looks for `PREFIX/share/config.site' if it exists, then
! 142: `PREFIX/etc/config.site' if it exists. Or, you can set the
! 143: `CONFIG_SITE' environment variable to the location of the site script.
! 144: A warning: not all `configure' scripts look for a site script.
! 145:
! 146: Operation Controls
! 147: ==================
! 148:
! 149: `configure' recognizes the following options to control how it
! 150: operates.
! 151:
! 152: `--cache-file=FILE'
! 153: Use and save the results of the tests in FILE instead of
! 154: `./config.cache'. Set FILE to `/dev/null' to disable caching, for
! 155: debugging `configure'.
! 156:
! 157: `--help'
! 158: Print a summary of the options to `configure', and exit.
! 159:
! 160: `--quiet'
! 161: `--silent'
! 162: `-q'
! 163: Do not print messages saying which checks are being made.
! 164:
! 165: `--srcdir=DIR'
! 166: Look for the package's source code in directory DIR. Usually
! 167: `configure' can determine that directory automatically.
! 168:
! 169: `--version'
! 170: Print the version of Autoconf used to generate the `configure'
! 171: script, and exit.
! 172:
! 173: `configure' also accepts some other, not widely useful, options.
