| 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. To do this, you must use a version of `make' that | |
| 73 supports the `VPATH' variable, such as GNU `make'. `cd' to the | |
| 74 directory where you want the object files and executables to go and run | |
| 75 the `configure' script. `configure' automatically checks for the | |
| 76 source code in the directory that `configure' is in and in `..'. | |
| 77 | |
| 78 If you have to use a `make' that does not supports the `VPATH' | |
| 79 variable, you have to compile the package for one architecture at a time | |
| 80 in the source code directory. After you have installed the package for | |
| 81 one architecture, use `make distclean' before reconfiguring for another | |
| 82 architecture. | |
| 83 | |
| 84 Installation Names | |
| 85 ================== | |
| 86 | |
| 87 By default, `make install' will install the package's files in | |
| 88 `/usr/local/bin', `/usr/local/man', etc. You can specify an | |
| 89 installation prefix other than `/usr/local' by giving `configure' the | |
| 90 option `--prefix=PATH'. | |
| 91 | |
| 92 You can specify separate installation prefixes for | |
| 93 architecture-specific files and architecture-independent files. If you | |
| 94 give `configure' the option `--exec-prefix=PATH', the package will use | |
| 95 PATH as the prefix for installing programs and libraries. | |
| 96 Documentation and other data files will still use the regular prefix. | |
| 97 | |
| 98 In addition, if you use an unusual directory layout you can give | |
| 99 options like `--bindir=PATH' to specify different values for particular | |
| 100 kinds of files. Run `configure --help' for a list of the directories | |
| 101 you can set and what kinds of files go in them. | |
| 102 | |
| 103 If the package supports it, you can cause programs to be installed | |
| 104 with an extra prefix or suffix on their names by giving `configure' the | |
| 105 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. | |
| 106 | |
| 107 Optional Features | |
| 108 ================= | |
| 109 | |
| 110 Some packages pay attention to `--enable-FEATURE' options to | |
| 111 `configure', where FEATURE indicates an optional part of the package. | |
| 112 They may also pay attention to `--with-PACKAGE' options, where PACKAGE | |
| 113 is something like `gnu-as' or `x' (for the X Window System). The | |
| 114 `README' should mention any `--enable-' and `--with-' options that the | |
| 115 package recognizes. | |
| 116 | |
| 117 For packages that use the X Window System, `configure' can usually | |
| 118 find the X include and library files automatically, but if it doesn't, | |
| 119 you can use the `configure' options `--x-includes=DIR' and | |
| 120 `--x-libraries=DIR' to specify their locations. | |
| 121 | |
| 122 Specifying the System Type | |
| 123 ========================== | |
| 124 | |
| 125 There may be some features `configure' can not figure out | |
| 126 automatically, but needs to determine by the type of host the package | |
| 127 will run on. Usually `configure' can figure that out, but if it prints | |
| 128 a message saying it can not guess the host type, give it the | |
| 129 `--host=TYPE' option. TYPE can either be a short name for the system | |
| 130 type, such as `sun4', or a canonical name with three fields: | |
| 131 CPU-COMPANY-SYSTEM | |
| 132 | |
| 133 See the file `config.sub' for the possible values of each field. If | |
| 134 `config.sub' isn't included in this package, then this package doesn't | |
| 135 need to know the host type. | |
| 136 | |
| 137 If you are building compiler tools for cross-compiling, you can also | |
| 138 use the `--target=TYPE' option to select the type of system they will | |
| 139 produce code for and the `--build=TYPE' option to select the type of | |
| 140 system on which you are compiling the package. | |
| 141 | |
| 142 Sharing Defaults | |
| 143 ================ | |
| 144 | |
| 145 If you want to set default values for `configure' scripts to share, | |
| 146 you can create a site shell script called `config.site' that gives | |
| 147 default values for variables like `CC', `cache_file', and `prefix'. | |
| 148 `configure' looks for `PREFIX/share/config.site' if it exists, then | |
| 149 `PREFIX/etc/config.site' if it exists. Or, you can set the | |
| 150 `CONFIG_SITE' environment variable to the location of the site script. | |
| 151 A warning: not all `configure' scripts look for a site script. | |
| 152 | |
| 153 Operation Controls | |
| 154 ================== | |
| 155 | |
| 156 `configure' recognizes the following options to control how it | |
| 157 operates. | |
| 158 | |
| 159 `--cache-file=FILE' | |
| 160 Use and save the results of the tests in FILE instead of | |
| 161 `./config.cache'. Set FILE to `/dev/null' to disable caching, for | |
| 162 debugging `configure'. | |
| 163 | |
| 164 `--help' | |
| 165 Print a summary of the options to `configure', and exit. | |
| 166 | |
| 167 `--quiet' | |
| 168 `--silent' | |
| 169 `-q' | |
| 170 Do not print messages saying which checks are being made. To | |
| 171 suppress all normal output, redirect it to `/dev/null' (any error | |
| 172 messages will still be shown). | |
| 173 | |
| 174 `--srcdir=DIR' | |
| 175 Look for the package's source code in directory DIR. Usually | |
| 176 `configure' can determine that directory automatically. | |
| 177 | |
| 178 `--version' | |
| 179 Print the version of Autoconf used to generate the `configure' | |
| 180 script, and exit. | |
| 181 | |
| 182 `configure' also accepts some other, not widely useful, options. |
