|
|
The `configure' shell script attempts to guess correct values for |
| 18 |
|
|
various system-dependent variables used during compilation. It uses |
| 19 |
|
|
those values to create a `Makefile' in each directory of the package. |
| 20 |
|
|
It may also create one or more `.h' files containing system-dependent |
| 21 |
|
|
definitions. Finally, it creates a shell script `config.status' that |
| 22 |
|
|
you can run in the future to recreate the current configuration, and a |
| 23 |
|
|
file `config.log' containing compiler output (useful mainly for |
| 24 |
|
|
debugging `configure'). |
| 25 |
|
|
|
| 26 |
|
|
It can also use an optional file (typically called `config.cache' |
| 27 |
|
|
and enabled with `--cache-file=config.cache' or simply `-C') that saves |
| 28 |
|
|
the results of its tests to speed up reconfiguring. (Caching is |
| 29 |
|
|
disabled by default to prevent problems with accidental use of stale |
| 30 |
|
|
cache files.) |
| 31 |
|
|
|
| 32 |
|
|
If you need to do unusual things to compile the package, please try |
| 33 |
|
|
to figure out how `configure' could check whether to do them, and mail |
| 34 |
|
|
diffs or instructions to the address given in the `README' so they can |
| 35 |
|
|
be considered for the next release. If you are using the cache, and at |
| 36 |
|
|
some point `config.cache' contains results you don't want to keep, you |
| 37 |
|
|
may remove or edit it. |
| 38 |
|
|
|
| 39 |
|
|
The file `configure.ac' (or `configure.in') is used to create |
| 40 |
|
|
`configure' by a program called `autoconf'. You only need |
| 41 |
|
|
`configure.ac' if you want to change it or regenerate `configure' using |
| 42 |
|
|
a newer version of `autoconf'. |
| 43 |
|
|
|
| 44 |
|
|
The simplest way to compile this package is: |
| 45 |
|
|
|
| 46 |
|
|
1. `cd' to the directory containing the package's source code and type |
| 47 |
|
|
`./configure' to configure the package for your system. If you're |
| 48 |
|
|
using `csh' on an old version of System V, you might need to type |
| 49 |
|
|
`sh ./configure' instead to prevent `csh' from trying to execute |
| 50 |
|
|
`configure' itself. |
| 51 |
|
|
|
| 52 |
|
|
Running `configure' takes awhile. While running, it prints some |
| 53 |
|
|
messages telling which features it is checking for. |
| 54 |
|
|
|
| 55 |
|
|
2. Type `make' to compile the package. |
| 56 |
|
|
|
| 57 |
|
|
3. Optionally, type `make check' to run any self-tests that come with |
| 58 |
|
|
the package. |
| 59 |
|
|
|
| 60 |
|
|
4. Type `make install' to install the programs and any data files and |
| 61 |
|
|
documentation. |
| 62 |
|
|
|
| 63 |
|
|
5. You can remove the program binaries and object files from the |
| 64 |
|
|
source code directory by typing `make clean'. To also remove the |
| 65 |
|
|
files that `configure' created (so you can compile the package for |
| 66 |
|
|
a different kind of computer), type `make distclean'. There is |
| 67 |
|
|
also a `make maintainer-clean' target, but that is intended mainly |
| 68 |
|
|
for the package's developers. If you use it, you may have to get |
| 69 |
|
|
all sorts of other programs in order to regenerate files that came |
| 70 |
|
|
with the distribution. |
| 71 |
|
|
|
| 72 |
|
|
Compilers and Options |
| 73 |
|
|
===================== |
| 74 |
|
|
|
| 75 |
|
|
Some systems require unusual options for compilation or linking that the |
| 76 |
|
|
`configure' script does not know about. Run `./configure --help' for |
| 77 |
|
|
details on some of the pertinent environment variables. |
| 78 |
|
|
|
| 79 |
|
|
You can give `configure' initial values for configuration parameters |
| 80 |
|
|
by setting variables in the command line or in the environment. Here |
| 81 |
|
|
is an example: |
| 82 |
|
|
|
| 83 |
|
|
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix |
| 84 |
|
|
|
| 85 |
|
|
*Note Defining Variables::, for more details. |
| 86 |
|
|
|
| 87 |
|
|
Compiling For Multiple Architectures |
| 88 |
|
|
==================================== |
| 89 |
|
|
|
| 90 |
|
|
You can compile the package for more than one kind of computer at the |
| 91 |
|
|
same time, by placing the object files for each architecture in their |
| 92 |
|
|
own directory. To do this, you must use a version of `make' that |
| 93 |
|
|
supports the `VPATH' variable, such as GNU `make'. `cd' to the |
| 94 |
|
|
directory where you want the object files and executables to go and run |
| 95 |
|
|
the `configure' script. `configure' automatically checks for the |
| 96 |
|
|
source code in the directory that `configure' is in and in `..'. |
| 97 |
|
|
|
| 98 |
|
|
If you have to use a `make' that does not support the `VPATH' |
| 99 |
|
|
variable, you have to compile the package for one architecture at a |
| 100 |
|
|
time in the source code directory. After you have installed the |
| 101 |
|
|
package for one architecture, use `make distclean' before reconfiguring |
| 102 |
|
|
for another architecture. |
| 103 |
|
|
|
| 104 |
|
|
Installation Names |
| 105 |
|
|
================== |
| 106 |
|
|
|
| 107 |
|
|
By default, `make install' will install the package's files in |
| 108 |
|
|
`/usr/local/bin', `/usr/local/man', etc. You can specify an |
| 109 |
|
|
installation prefix other than `/usr/local' by giving `configure' the |
| 110 |
|
|
option `--prefix=PREFIX'. |
| 111 |
|
|
|
| 112 |
|
|
You can specify separate installation prefixes for |
| 113 |
|
|
architecture-specific files and architecture-independent files. If you |
| 114 |
|
|
give `configure' the option `--exec-prefix=PREFIX', the package will |
| 115 |
|
|
use PREFIX as the prefix for installing programs and libraries. |
| 116 |
|
|
Documentation and other data files will still use the regular prefix. |
| 117 |
|
|
|
| 118 |
|
|
In addition, if you use an unusual directory layout you can give |
| 119 |
|
|
options like `--bindir=DIR' to specify different values for particular |
| 120 |
|
|
kinds of files. Run `configure --help' for a list of the directories |
| 121 |
|
|
you can set and what kinds of files go in them. |
| 122 |
|
|
|
| 123 |
|
|
If the package supports it, you can cause programs to be installed |
| 124 |
|
|
with an extra prefix or suffix on their names by giving `configure' the |
| 125 |
|
|
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. |
| 126 |
|
|
|
| 127 |
|
|
Optional Features |
| 128 |
|
|
================= |
| 129 |
|
|
|
| 130 |
|
|
Some packages pay attention to `--enable-FEATURE' options to |
| 131 |
|
|
`configure', where FEATURE indicates an optional part of the package. |
| 132 |
|
|
They may also pay attention to `--with-PACKAGE' options, where PACKAGE |
| 133 |
|
|
is something like `gnu-as' or `x' (for the X Window System). The |
| 134 |
|
|
`README' should mention any `--enable-' and `--with-' options that the |
| 135 |
|
|
package recognizes. |
| 136 |
|
|
|
| 137 |
|
|
For packages that use the X Window System, `configure' can usually |
| 138 |
|
|
find the X include and library files automatically, but if it doesn't, |
| 139 |
|
|
you can use the `configure' options `--x-includes=DIR' and |
| 140 |
|
|
`--x-libraries=DIR' to specify their locations. |
| 141 |
|
|
|
| 142 |
|
|
Specifying the System Type |
| 143 |
|
|
========================== |
| 144 |
|
|
|
| 145 |
|
|
There may be some features `configure' cannot figure out automatically, |
| 146 |
|
|
but needs to determine by the type of machine the package will run on. |
| 147 |
|
|
Usually, assuming the package is built to be run on the _same_ |
| 148 |
|
|
architectures, `configure' can figure that out, but if it prints a |
| 149 |
|
|
message saying it cannot guess the machine type, give it the |
| 150 |
|
|
`--build=TYPE' option. TYPE can either be a short name for the system |
| 151 |
|
|
type, such as `sun4', or a canonical name which has the form: |
| 152 |
|
|
|
| 153 |
|
|
CPU-COMPANY-SYSTEM |
| 154 |
|
|
|
| 155 |
|
|
where SYSTEM can have one of these forms: |
| 156 |
|
|
|
| 157 |
|
|
OS KERNEL-OS |
| 158 |
|
|
|
| 159 |
|
|
See the file `config.sub' for the possible values of each field. If |
| 160 |
|
|
`config.sub' isn't included in this package, then this package doesn't |
| 161 |
|
|
need to know the machine type. |
| 162 |
|
|
|
| 163 |
|
|
If you are _building_ compiler tools for cross-compiling, you should |
| 164 |
|
|
use the `--target=TYPE' option to select the type of system they will |
| 165 |
|
|
produce code for. |
| 166 |
|
|
|
| 167 |
|
|
If you want to _use_ a cross compiler, that generates code for a |
| 168 |
|
|
platform different from the build platform, you should specify the |
| 169 |
|
|
"host" platform (i.e., that on which the generated programs will |
| 170 |
|
|
eventually be run) with `--host=TYPE'. |
| 171 |
|
|
|
| 172 |
|
|
Sharing Defaults |
| 173 |
|
|
================ |
| 174 |
|
|
|
| 175 |
|
|
If you want to set default values for `configure' scripts to share, you |
| 176 |
|
|
can create a site shell script called `config.site' that gives default |
| 177 |
|
|
values for variables like `CC', `cache_file', and `prefix'. |
| 178 |
|
|
`configure' looks for `PREFIX/share/config.site' if it exists, then |
| 179 |
|
|
`PREFIX/etc/config.site' if it exists. Or, you can set the |
| 180 |
|
|
`CONFIG_SITE' environment variable to the location of the site script. |
| 181 |
|
|
A warning: not all `configure' scripts look for a site script. |
| 182 |
|
|
|
| 183 |
|
|
Defining Variables |
| 184 |
|
|
================== |
| 185 |
|
|
|
| 186 |
|
|
Variables not defined in a site shell script can be set in the |
| 187 |
|
|
environment passed to `configure'. However, some packages may run |
| 188 |
|
|
configure again during the build, and the customized values of these |
| 189 |
|
|
variables may be lost. In order to avoid this problem, you should set |
| 190 |
|
|
them in the `configure' command line, using `VAR=value'. For example: |
| 191 |
|
|
|
| 192 |
|
|
./configure CC=/usr/local2/bin/gcc |
| 193 |
|
|
|
| 194 |
|
|
will cause the specified gcc to be used as the C compiler (unless it is |
| 195 |
|
|
overridden in the site shell script). |
| 196 |
|
|
|
| 197 |
|
|
`configure' Invocation |
| 198 |
|
|
====================== |
| 199 |
|
|
|
| 200 |
|
|
`configure' recognizes the following options to control how it operates. |
| 201 |
|
|
|
| 202 |
|
|
`--help' |
| 203 |
|
|
`-h' |
| 204 |
|
|
Print a summary of the options to `configure', and exit. |
| 205 |
|
|
|
| 206 |
|
|
`--version' |
| 207 |
|
|
`-V' |
| 208 |
|
|
Print the version of Autoconf used to generate the `configure' |
| 209 |
|
|
script, and exit. |
| 210 |
|
|
|
| 211 |
|
|
`--cache-file=FILE' |
| 212 |
|
|
Enable the cache: use and save the results of the tests in FILE, |
| 213 |
|
|
traditionally `config.cache'. FILE defaults to `/dev/null' to |
| 214 |
|
|
disable caching. |
| 215 |
|
|
|
| 216 |
|
|
`--config-cache' |
| 217 |
|
|
`-C' |
| 218 |
|
|
Alias for `--cache-file=config.cache'. |
| 219 |
|
|
|
| 220 |
|
|
`--quiet' |
| 221 |
|
|
`--silent' |
| 222 |
|
|
`-q' |
| 223 |
|
|
Do not print messages saying which checks are being made. To |
| 224 |
|
|
suppress all normal output, redirect it to `/dev/null' (any error |
| 225 |
|
|
messages will still be shown). |
| 226 |
|
|
|
| 227 |
|
|
`--srcdir=DIR' |
| 228 |
|
|
Look for the package's source code in directory DIR. Usually |
| 229 |
|
|
`configure' can determine that directory automatically. |
| 230 |
|
|
|
| 231 |
|
|
`configure' also accepts some other, not widely useful, options. Run |
| 232 |
|
|
`configure --help' for more details. |
| 233 |
|
|
|
