| 2 | ================== |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 3 | |
Jari Aalto | d166f04 | 1997-06-05 14:59:13 +0000 | [diff] [blame] | 4 | These are installation instructions for Bash. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 5 | |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 6 | The simplest way to compile Bash is: |
| 7 | |
| 8 | 1. `cd' to the directory containing the source code and type |
| 9 | `./configure' to configure Bash for your system. If you're using |
| 10 | `csh' on an old version of System V, you might need to type `sh |
| 11 | ./configure' instead to prevent `csh' from trying to execute |
| 12 | `configure' itself. |
| 13 | |
| 14 | Running `configure' takes some time. While running, it prints |
| 15 | messages telling which features it is checking for. |
| 16 | |
| 17 | 2. Type `make' to compile Bash and build the `bashbug' bug reporting |
| 18 | script. |
| 19 | |
| 20 | 3. Optionally, type `make tests' to run the Bash test suite. |
| 21 | |
| 22 | 4. Type `make install' to install `bash' and `bashbug'. This will |
| 23 | also install the manual pages and Info file. |
| 24 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 25 | The `configure' shell script attempts to guess correct values for |
| 26 | various system-dependent variables used during compilation. It uses |
| 27 | those values to create a `Makefile' in each directory of the package |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 28 | (the top directory, the `builtins', `doc', and `support' directories, |
| 29 | each directory under `lib', and several others). It also creates a |
| 30 | `config.h' file containing system-dependent definitions. Finally, it |
| 31 | creates a shell script named `config.status' that you can run in the |
| 32 | future to recreate the current configuration, a file `config.cache' |
| 33 | that saves the results of its tests to speed up reconfiguring, and a |
| 34 | file `config.log' containing compiler output (useful mainly for |
| 35 | debugging `configure'). If at some point `config.cache' contains |
| 36 | results you don't want to keep, you may remove or edit it. |
| 37 | |
| 38 | To find out more about the options and arguments that the `configure' |
| 39 | script understands, type |
| 40 | |
| 41 | bash-2.04$ ./configure --help |
| 42 | |
| 43 | at the Bash prompt in your Bash source directory. |

Jari Aalto | b72432f | 1999-02-19 17:11:39 +0000 | [diff] [blame] | 45 | If you need to do unusual things to compile Bash, please try to figure |
| 46 | out how `configure' could check whether or not to do them, and mail |
| 47 | diffs or instructions to <bash-maintainers@gnu.org> so they can be |
| 48 | considered for the next release. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 49 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 50 | The file `configure.in' is used to create `configure' by a program |
| 51 | called Autoconf. You only need `configure.in' if you want to change it |
| 52 | or regenerate `configure' using a newer version of Autoconf. If you do |
Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 53 | this, make sure you are using Autoconf version 2.50 or newer. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 54 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 55 | You can remove the program binaries and object files from the source |
| 56 | code directory by typing `make clean'. To also remove the files that |
| 57 | `configure' created (so you can compile Bash for a different kind of |
| 58 | computer), type `make distclean'. |

| 61 | ===================== |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 62 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 63 | Some systems require unusual options for compilation or linking that |
| 64 | the `configure' script does not know about. You can give `configure' |
| 65 | initial values for variables by setting them in the environment. Using |
| 66 | a Bourne-compatible shell, you can do that on the command line like |
| 67 | this: |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 68 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 69 | CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 70 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 71 | On systems that have the `env' program, you can do it like this: |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 72 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 73 | env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 74 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 75 | The configuration process uses GCC to build Bash if it is available. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 77 | Compiling For Multiple Architectures |
| 78 | ==================================== |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 79 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 80 | You can compile Bash for more than one kind of computer at the same |
| 81 | time, by placing the object files for each architecture in their own |
| 82 | directory. To do this, you must use a version of `make' that supports |
| 83 | the `VPATH' variable, such as GNU `make'. `cd' to the directory where |
| 84 | you want the object files and executables to go and run the `configure' |
| 85 | script from the source directory. You may need to supply the |
| 86 | `--srcdir=PATH' argument to tell `configure' where the source files |
| 87 | are. `configure' automatically checks for the source code in the |
| 88 | directory that `configure' is in and in `..'. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 89 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 90 | If you have to use a `make' that does not supports the `VPATH' |
| 91 | variable, you can compile Bash for one architecture at a time in the |
| 92 | source code directory. After you have installed Bash for one |
| 93 | architecture, use `make distclean' before reconfiguring for another |
| 94 | architecture. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 95 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 96 | Alternatively, if your system supports symbolic links, you can use the |
| 97 | `support/mkclone' script to create a build tree which has symbolic |
| 98 | links back to each file in the source directory. Here's an example |
| 99 | that creates a build directory in the current directory from a source |
| 100 | directory `/usr/gnu/src/bash-2.0': |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 101 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 102 | bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 . |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 103 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 104 | The `mkclone' script requires Bash, so you must have already built Bash |
| 105 | for at least one architecture before you can create build directories |
| 106 | for other architectures. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 111 | By default, `make install' will install into `/usr/local/bin', |
| 112 | `/usr/local/man', etc. You can specify an installation prefix other |
Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 113 | than `/usr/local' by giving `configure' the option `--prefix=PATH', or |
| 114 | by specifying a value for the `DESTDIR' `make' variable when running |
| 115 | `make install'. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 116 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 117 | You can specify separate installation prefixes for |
| 118 | architecture-specific files and architecture-independent files. If you |
Jari Aalto | b72432f | 1999-02-19 17:11:39 +0000 | [diff] [blame] | 119 | give `configure' the option `--exec-prefix=PATH', `make install' will |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 120 | use PATH as the prefix for installing programs and libraries. |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 121 | Documentation and other data files will still use the regular prefix. |

Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 125 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 126 | There may be some features `configure' can not figure out |
Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 127 | automatically, but need to determine by the type of host Bash will run |
Jari Aalto | b72432f | 1999-02-19 17:11:39 +0000 | [diff] [blame] | 128 | on. Usually `configure' can figure that out, but if it prints a |
| 129 | message saying it can not guess the host type, give it the |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 130 | `--host=TYPE' option. `TYPE' can either be a short name for the system |
| 131 | type, such as `sun4', or a canonical name with three fields: |
Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 132 | `CPU-COMPANY-SYSTEM' (e.g., `i386-unknown-freebsd4.2'). |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 133 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 134 | See the file `support/config.sub' for the possible values of each field. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 139 | If you want to set default values for `configure' scripts to share, you |
| 140 | can create a site shell script called `config.site' that gives default |
| 141 | values for variables like `CC', `cache_file', and `prefix'. `configure' |
| 142 | looks for `PREFIX/share/config.site' if it exists, then |
| 143 | `PREFIX/etc/config.site' if it exists. Or, you can set the |
| 144 | `CONFIG_SITE' environment variable to the location of the site script. |
| 145 | A warning: the Bash `configure' looks for a site script, but not all |
| 146 | `configure' scripts do. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 151 | `configure' recognizes the following options to control how it operates. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 153 | `--cache-file=FILE' |
| 154 | Use and save the results of the tests in FILE instead of |
| 155 | `./config.cache'. Set FILE to `/dev/null' to disable caching, for |
| 156 | debugging `configure'. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 157 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 158 | `--help' |
| 159 | Print a summary of the options to `configure', and exit. |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 166 | `--srcdir=DIR' |
| 167 | Look for the Bash source code in directory DIR. Usually |
| 168 | `configure' can determine that directory automatically. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 169 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 170 | `--version' |

Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 180 | The Bash `configure' has a number of `--enable-FEATURE' options, where |
Jari Aalto | b72432f | 1999-02-19 17:11:39 +0000 | [diff] [blame] | 181 | FEATURE indicates an optional part of Bash. There are also several |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 182 | `--with-PACKAGE' options, where PACKAGE is something like `bash-malloc' |
Jari Aalto | b72432f | 1999-02-19 17:11:39 +0000 | [diff] [blame] | 183 | or `purify'. To turn off the default use of a package, use |
| 184 | `--without-PACKAGE'. To configure Bash without a feature that is |
| 185 | enabled by default, use `--disable-FEATURE'. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 186 | |
Jari Aalto | ccc6cda | 1996-12-23 17:02:34 +0000 | [diff] [blame] | 187 | Here is a complete list of the `--enable-' and `--with-' options that |
| 188 | the Bash `configure' recognizes. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 189 | |
Jari Aalto | d166f04 | 1997-06-05 14:59:13 +0000 | [diff] [blame] | 190 | `--with-afs' |
| 191 | Define if you are using the Andrew File System from Transarc. |
| 192 | |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 193 | `--with-bash-malloc' |
| 194 | Use the Bash version of `malloc' in `lib/malloc/malloc.c'. This |
| 195 | is not the same `malloc' that appears in GNU libc, but an older |
| 196 | version derived from the 4.2 BSD `malloc'. This `malloc' is very |
| 197 | fast, but wastes some space on each allocation. This option is |
| 198 | enabled by default. The `NOTES' file contains a list of systems |
| 199 | for which this should be turned off, and `configure' disables this |
| 200 | option automatically for a number of systems. |
| 201 | |
Jari Aalto | d166f04 | 1997-06-05 14:59:13 +0000 | [diff] [blame] | 202 | `--with-curses' |
| 203 | Use the curses library instead of the termcap library. This should |
| 204 | be supplied if your system has an inadequate or incomplete termcap |
| 205 | database. |
Jari Aalto | 726f638 | 1996-08-26 18:22:31 +0000 | [diff] [blame] | 206 | |

Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 208 | A synonym for `--with-bash-malloc'. |

Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 210 | `--with-installed-readline[=PREFIX]' |
Jari Aalto | bb70624 | 2000-03-17 21:46:59 +0000 | [diff] [blame] | 211 | Define this to make Bash link with a locally-installed version of |
| 212 | Readline rather than the version in `lib/readline'. This works |
Jari Aalto | f73dda0 | 2001-11-13 17:56:06 +0000 | [diff] [blame^] | 213 | only with Readline 4.2 and later versions. If PREFIX is `yes' or |
| 214 | not supplied, `configure' uses the values of the make variables |

| 216 | default, to find the installed version of Readline if it is not in |
| 217 | the standard system include and library directories. If PREFIX is |
| 218 | `no', Bash links with the version in `lib/readline'. If PREFIX is |
