The following 179acbb460Smrgmore-detailed instructions are generic; see the `README' file for 18ef516338Smrginstructions specific to this package. Some packages provide this 19ef516338Smrg`INSTALL' file but do not implement all of the features documented 20ef516338Smrgbelow. The lack of an optional feature in a given package is not 21ef516338Smrgnecessarily a bug. More recommendations for GNU packages can be found 22ef516338Smrgin *note Makefile Conventions: (standards)Makefile Conventions. 239acbb460Smrg 249acbb460Smrg The `configure' shell script attempts to guess correct values for 259acbb460Smrgvarious system-dependent variables used during compilation. It uses 269acbb460Smrgthose values to create a `Makefile' in each directory of the package. 279acbb460SmrgIt may also create one or more `.h' files containing system-dependent 289acbb460Smrgdefinitions. Finally, it creates a shell script `config.status' that 299acbb460Smrgyou can run in the future to recreate the current configuration, and a 309acbb460Smrgfile `config.log' containing compiler output (useful mainly for 319acbb460Smrgdebugging `configure'). 329acbb460Smrg 339acbb460Smrg It can also use an optional file (typically called `config.cache' 349acbb460Smrgand enabled with `--cache-file=config.cache' or simply `-C') that saves 359acbb460Smrgthe results of its tests to speed up reconfiguring. Caching is 369acbb460Smrgdisabled by default to prevent problems with accidental use of stale 379acbb460Smrgcache files. 389acbb460Smrg 399acbb460Smrg If you need to do unusual things to compile the package, please try 409acbb460Smrgto figure out how `configure' could check whether to do them, and mail 419acbb460Smrgdiffs or instructions to the address given in the `README' so they can 429acbb460Smrgbe considered for the next release. If you are using the cache, and at 439acbb460Smrgsome point `config.cache' contains results you don't want to keep, you 449acbb460Smrgmay remove or edit it. 459acbb460Smrg 469acbb460Smrg The file `configure.ac' (or `configure.in') is used to create 479acbb460Smrg`configure' by a program called `autoconf'. You need `configure.ac' if 489acbb460Smrgyou want to change it or regenerate `configure' using a newer version 499acbb460Smrgof `autoconf'. 509acbb460Smrg 51ef516338Smrg The simplest way to compile this package is: 529acbb460Smrg 539acbb460Smrg 1. `cd' to the directory containing the package's source code and type 549acbb460Smrg `./configure' to configure the package for your system. 559acbb460Smrg 569acbb460Smrg Running `configure' might take a while. While running, it prints 579acbb460Smrg some messages telling which features it is checking for. 589acbb460Smrg 599acbb460Smrg 2. Type `make' to compile the package. 609acbb460Smrg 619acbb460Smrg 3. Optionally, type `make check' to run any self-tests that come with 62ef516338Smrg the package, generally using the just-built uninstalled binaries. 639acbb460Smrg 649acbb460Smrg 4. Type `make install' to install the programs and any data files and 65ef516338Smrg documentation. When installing into a prefix owned by root, it is 66ef516338Smrg recommended that the package be configured and built as a regular 67ef516338Smrg user, and only the `make install' phase executed with root 68ef516338Smrg privileges. 69ef516338Smrg 70ef516338Smrg 5. Optionally, type `make installcheck' to repeat any self-tests, but 71ef516338Smrg this time using the binaries in their final installed location. 72ef516338Smrg This target does not install anything. Running this target as a 73ef516338Smrg regular user, particularly if the prior `make install' required 74ef516338Smrg root privileges, verifies that the installation completed 75ef516338Smrg correctly. 76ef516338Smrg 77ef516338Smrg 6. You can remove the program binaries and object files from the 789acbb460Smrg source code directory by typing `make clean'. To also remove the 799acbb460Smrg files that `configure' created (so you can compile the package for 809acbb460Smrg a different kind of computer), type `make distclean'. There is 819acbb460Smrg also a `make maintainer-clean' target, but that is intended mainly 829acbb460Smrg for the package's developers. If you use it, you may have to get 839acbb460Smrg all sorts of other programs in order to regenerate files that came 849acbb460Smrg with the distribution. 859acbb460Smrg 86ef516338Smrg 7. Often, you can also type `make uninstall' to remove the installed 87ef516338Smrg files again. In practice, not all packages have tested that 88ef516338Smrg uninstallation works correctly, even though it is required by the 89ef516338Smrg GNU Coding Standards. 90ef516338Smrg 91ef516338Smrg 8. Some packages, particularly those that use Automake, provide `make 92ef516338Smrg distcheck', which can by used by developers to test that all other 93ef516338Smrg targets like `make install' and `make uninstall' work correctly. 94ef516338Smrg This target is generally not run by end users. 959acbb460Smrg 969acbb460SmrgCompilers and Options 979acbb460Smrg===================== 989acbb460Smrg 999acbb460Smrg Some systems require unusual options for compilation or linking that 1009acbb460Smrgthe `configure' script does not know about. Run `./configure --help' 1019acbb460Smrgfor details on some of the pertinent environment variables. 1029acbb460Smrg 1039acbb460Smrg You can give `configure' initial values for configuration parameters 1049acbb460Smrgby setting variables in the command line or in the environment. Here 1059acbb460Smrgis an example: 1069acbb460Smrg 1079acbb460Smrg ./configure CC=c99 CFLAGS=-g LIBS=-lposix 1089acbb460Smrg 1099acbb460Smrg *Note Defining Variables::, for more details. 1109acbb460Smrg 1119acbb460SmrgCompiling For Multiple Architectures 1129acbb460Smrg==================================== 1139acbb460Smrg 1149acbb460Smrg You can compile the package for more than one kind of computer at the 1159acbb460Smrgsame time, by placing the object files for each architecture in their 1169acbb460Smrgown directory. To do this, you can use GNU `make'. `cd' to the 1179acbb460Smrgdirectory where you want the object files and executables to go and run 1189acbb460Smrgthe `configure' script. `configure' automatically checks for the 119ef516338Smrgsource code in the directory that `configure' is in and in `..'. This 120ef516338Smrgis known as a "VPATH" build. 1219acbb460Smrg 1229acbb460Smrg With a non-GNU `make', it is safer to compile the package for one 1239acbb460Smrgarchitecture at a time in the source code directory. After you have 1249acbb460Smrginstalled the package for one architecture, use `make distclean' before 1259acbb460Smrgreconfiguring for another architecture. 1269acbb460Smrg 1279acbb460Smrg On MacOS X 10.5 and later systems, you can create libraries and 1289acbb460Smrgexecutables that work on multiple system types--known as "fat" or 1299acbb460Smrg"universal" binaries--by specifying multiple `-arch' options to the 1309acbb460Smrgcompiler but only a single `-arch' option to the preprocessor. Like 1319acbb460Smrgthis: 1329acbb460Smrg 1339acbb460Smrg ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1349acbb460Smrg CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1359acbb460Smrg CPP="gcc -E" CXXCPP="g++ -E" 1369acbb460Smrg 1379acbb460Smrg This is not guaranteed to produce working output in all cases, you 1389acbb460Smrgmay have to build one architecture at a time and combine the results 1399acbb460Smrgusing the `lipo' tool if you have problems. 1409acbb460Smrg 1419acbb460SmrgInstallation Names 1429acbb460Smrg================== 1439acbb460Smrg 1449acbb460Smrg By default, `make install' installs the package's commands under 1459acbb460Smrg`/usr/local/bin', include files under `/usr/local/include', etc. You 1469acbb460Smrgcan specify an installation prefix other than `/usr/local' by giving 147ef516338Smrg`configure' the option `--prefix=PREFIX', where PREFIX must be an 148ef516338Smrgabsolute file name. 1499acbb460Smrg 1509acbb460Smrg You can specify separate installation prefixes for 1519acbb460Smrgarchitecture-specific files and architecture-independent files. If you 1529acbb460Smrgpass the option `--exec-prefix=PREFIX' to `configure', the package uses 1539acbb460SmrgPREFIX as the prefix for installing programs and libraries. 1549acbb460SmrgDocumentation and other data files still use the regular prefix. 1559acbb460Smrg 1569acbb460Smrg In addition, if you use an unusual directory layout you can give 1579acbb460Smrgoptions like `--bindir=DIR' to specify different values for particular 1589acbb460Smrgkinds of files. Run `configure --help' for a list of the directories 159ef516338Smrgyou can set and what kinds of files go in them. In general, the 160ef516338Smrgdefault for these options is expressed in terms of `${prefix}', so that 161ef516338Smrgspecifying just `--prefix' will affect all of the other directory 162ef516338Smrgspecifications that were not explicitly provided. 163ef516338Smrg 164ef516338Smrg The most portable way to affect installation locations is to pass the 165ef516338Smrgcorrect locations to `configure'; however, many packages provide one or 166ef516338Smrgboth of the following shortcuts of passing variable assignments to the 167ef516338Smrg`make install' command line to change installation locations without 168ef516338Smrghaving to reconfigure or recompile. 169ef516338Smrg 170ef516338Smrg The first method involves providing an override variable for each 171ef516338Smrgaffected directory. For example, `make install 172ef516338Smrgprefix=/alternate/directory' will choose an alternate location for all 173ef516338Smrgdirectory configuration variables that were expressed in terms of 174ef516338Smrg`${prefix}'. Any directories that were specified during `configure', 175ef516338Smrgbut not in terms of `${prefix}', must each be overridden at install 176ef516338Smrgtime for the entire installation to be relocated. The approach of 177ef516338Smrgmakefile variable overrides for each directory variable is required by 178ef516338Smrgthe GNU Coding Standards, and ideally causes no recompilation. 179ef516338SmrgHowever, some platforms have known limitations with the semantics of 180ef516338Smrgshared libraries that end up requiring recompilation when using this 181ef516338Smrgmethod, particularly noticeable in packages that use GNU Libtool. 182ef516338Smrg 183ef516338Smrg The second method involves providing the `DESTDIR' variable. For 184ef516338Smrgexample, `make install DESTDIR=/alternate/directory' will prepend 185ef516338Smrg`/alternate/directory' before all installation names. The approach of 186ef516338Smrg`DESTDIR' overrides is not required by the GNU Coding Standards, and 187ef516338Smrgdoes not work on platforms that have drive letters. On the other hand, 188ef516338Smrgit does better at avoiding recompilation issues, and works well even 189ef516338Smrgwhen some directory options were not specified in terms of `${prefix}' 190ef516338Smrgat `configure' time. 191ef516338Smrg 192ef516338SmrgOptional Features 193ef516338Smrg================= 1949acbb460Smrg 1959acbb460Smrg If the package supports it, you can cause programs to be installed 1969acbb460Smrgwith an extra prefix or suffix on their names by giving `configure' the 1979acbb460Smrgoption `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 1989acbb460Smrg 1999acbb460Smrg Some packages pay attention to `--enable-FEATURE' options to 2009acbb460Smrg`configure', where FEATURE indicates an optional part of the package. 2019acbb460SmrgThey may also pay attention to `--with-PACKAGE' options, where PACKAGE 2029acbb460Smrgis something like `gnu-as' or `x' (for the X Window System). The 2039acbb460Smrg`README' should mention any `--enable-' and `--with-' options that the 2049acbb460Smrgpackage recognizes. 2059acbb460Smrg 2069acbb460Smrg For packages that use the X Window System, `configure' can usually 2079acbb460Smrgfind the X include and library files automatically, but if it doesn't, 2089acbb460Smrgyou can use the `configure' options `--x-includes=DIR' and 2099acbb460Smrg`--x-libraries=DIR' to specify their locations. 2109acbb460Smrg 211ef516338Smrg Some packages offer the ability to configure how verbose the 212ef516338Smrgexecution of `make' will be. For these packages, running `./configure 213ef516338Smrg--enable-silent-rules' sets the default to minimal output, which can be 214ef516338Smrgoverridden with `make V=1'; while running `./configure 215ef516338Smrg--disable-silent-rules' sets the default to verbose, which can be 216ef516338Smrgoverridden with `make V=0'. 217ef516338Smrg 2189acbb460SmrgParticular systems 2199acbb460Smrg================== 2209acbb460Smrg 2219acbb460Smrg On HP-UX, the default C compiler is not ANSI C compatible. If GNU 2229acbb460SmrgCC is not installed, it is recommended to use the following options in 2239acbb460Smrgorder to use an ANSI C compiler: 2249acbb460Smrg 225ef516338Smrg ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" 2269acbb460Smrg 2279acbb460Smrgand if that doesn't work, install pre-built binaries of GCC for HP-UX. 2289acbb460Smrg 229ef516338Smrg HP-UX `make' updates targets which have the same time stamps as 230ef516338Smrgtheir prerequisites, which makes it generally unusable when shipped 231ef516338Smrggenerated files such as `configure' are involved. Use GNU `make' 232ef516338Smrginstead. 233ef516338Smrg 2349acbb460Smrg On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 2359acbb460Smrgparse its `<wchar.h>' header file. The option `-nodtk' can be used as 2369acbb460Smrga workaround. If GNU CC is not installed, it is therefore recommended 2379acbb460Smrgto try 2389acbb460Smrg 2399acbb460Smrg ./configure CC="cc" 2409acbb460Smrg 2419acbb460Smrgand if that doesn't work, try 2429acbb460Smrg 2439acbb460Smrg ./configure CC="cc -nodtk" 2449acbb460Smrg 245ef516338Smrg On Solaris, don't put `/usr/ucb' early in your `PATH'. This 246ef516338Smrgdirectory contains several dysfunctional programs; working variants of 247ef516338Smrgthese programs are available in `/usr/bin'. So, if you need `/usr/ucb' 248ef516338Smrgin your `PATH', put it _after_ `/usr/bin'. 249ef516338Smrg 250ef516338Smrg On Haiku, software installed for all users goes in `/boot/common', 251ef516338Smrgnot `/usr/local'. It is recommended to use the following options: 252ef516338Smrg 253ef516338Smrg ./configure --prefix=/boot/common 254ef516338Smrg 2559acbb460SmrgSpecifying the System Type 2569acbb460Smrg========================== 2579acbb460Smrg 2589acbb460Smrg There may be some features `configure' cannot figure out 2599acbb460Smrgautomatically, but needs to determine by the type of machine the package 2609acbb460Smrgwill run on. Usually, assuming the package is built to be run on the 2619acbb460Smrg_same_ architectures, `configure' can figure that out, but if it prints 2629acbb460Smrga message saying it cannot guess the machine type, give it the 2639acbb460Smrg`--build=TYPE' option. TYPE can either be a short name for the system 2649acbb460Smrgtype, such as `sun4', or a canonical name which has the form: 2659acbb460Smrg 2669acbb460Smrg CPU-COMPANY-SYSTEM 2679acbb460Smrg 2689acbb460Smrgwhere SYSTEM can have one of these forms: 2699acbb460Smrg 270ef516338Smrg OS 271ef516338Smrg KERNEL-OS 2729acbb460Smrg 2739acbb460Smrg See the file `config.sub' for the possible values of each field. If 2749acbb460Smrg`config.sub' isn't included in this package, then this package doesn't 2759acbb460Smrgneed to know the machine type. 2769acbb460Smrg 2779acbb460Smrg If you are _building_ compiler tools for cross-compiling, you should 2789acbb460Smrguse the option `--target=TYPE' to select the type of system they will 2799acbb460Smrgproduce code for. 2809acbb460Smrg 2819acbb460Smrg If you want to _use_ a cross compiler, that generates code for a 2829acbb460Smrgplatform different from the build platform, you should specify the 2839acbb460Smrg"host" platform (i.e., that on which the generated programs will 2849acbb460Smrgeventually be run) with `--host=TYPE'. 2859acbb460Smrg 2869acbb460SmrgSharing Defaults 2879acbb460Smrg================ 2889acbb460Smrg 2899acbb460Smrg If you want to set default values for `configure' scripts to share, 2909acbb460Smrgyou can create a site shell script called `config.site' that gives 2919acbb460Smrgdefault values for variables like `CC', `cache_file', and `prefix'. 2929acbb460Smrg`configure' looks for `PREFIX/share/config.site' if it exists, then 2939acbb460Smrg`PREFIX/etc/config.site' if it exists. Or, you can set the 2949acbb460Smrg`CONFIG_SITE' environment variable to the location of the site script. 2959acbb460SmrgA warning: not all `configure' scripts look for a site script. 2969acbb460Smrg 2979acbb460SmrgDefining Variables 2989acbb460Smrg================== 2999acbb460Smrg 3009acbb460Smrg Variables not defined in a site shell script can be set in the 3019acbb460Smrgenvironment passed to `configure'. However, some packages may run 3029acbb460Smrgconfigure again during the build, and the customized values of these 3039acbb460Smrgvariables may be lost. In order to avoid this problem, you should set 3049acbb460Smrgthem in the `configure' command line, using `VAR=value'. For example: 3059acbb460Smrg 3069acbb460Smrg ./configure CC=/usr/local2/bin/gcc 3079acbb460Smrg 3089acbb460Smrgcauses the specified `gcc' to be used as the C compiler (unless it is 3099acbb460Smrgoverridden in the site shell script). 3109acbb460Smrg 3119acbb460SmrgUnfortunately, this technique does not work for `CONFIG_SHELL' due to 3129acbb460Smrgan Autoconf bug. Until the bug is fixed you can use this workaround: 3139acbb460Smrg 3149acbb460Smrg CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash 3159acbb460Smrg 3169acbb460Smrg`configure' Invocation 3179acbb460Smrg====================== 3189acbb460Smrg 3199acbb460Smrg `configure' recognizes the following options to control how it 3209acbb460Smrgoperates. 3219acbb460Smrg 3229acbb460Smrg`--help' 3239acbb460Smrg`-h' 3249acbb460Smrg Print a summary of all of the options to `configure', and exit. 3259acbb460Smrg 3269acbb460Smrg`--help=short' 3279acbb460Smrg`--help=recursive' 3289acbb460Smrg Print a summary of the options unique to this package's 3299acbb460Smrg `configure', and exit. The `short' variant lists options used 3309acbb460Smrg only in the top level, while the `recursive' variant lists options 3319acbb460Smrg also present in any nested packages. 3329acbb460Smrg 3339acbb460Smrg`--version' 3349acbb460Smrg`-V' 3359acbb460Smrg Print the version of Autoconf used to generate the `configure' 3369acbb460Smrg script, and exit. 3379acbb460Smrg 3389acbb460Smrg`--cache-file=FILE' 3399acbb460Smrg Enable the cache: use and save the results of the tests in FILE, 3409acbb460Smrg traditionally `config.cache'. FILE defaults to `/dev/null' to 3419acbb460Smrg disable caching. 3429acbb460Smrg 3439acbb460Smrg`--config-cache' 3449acbb460Smrg`-C' 3459acbb460Smrg Alias for `--cache-file=config.cache'. 3469acbb460Smrg 3479acbb460Smrg`--quiet' 3489acbb460Smrg`--silent' 3499acbb460Smrg`-q' 3509acbb460Smrg Do not print messages saying which checks are being made. To 3519acbb460Smrg suppress all normal output, redirect it to `/dev/null' (any error 3529acbb460Smrg messages will still be shown). 3539acbb460Smrg 3549acbb460Smrg`--srcdir=DIR' 3559acbb460Smrg Look for the package's source code in directory DIR. Usually 3569acbb460Smrg `configure' can determine that directory automatically. 3579acbb460Smrg 3589acbb460Smrg`--prefix=DIR' 359ef516338Smrg Use DIR as the installation prefix. *note Installation Names:: 3609acbb460Smrg for more details, including other options available for fine-tuning 3619acbb460Smrg the installation locations. 3629acbb460Smrg 3639acbb460Smrg`--no-create' 3649acbb460Smrg`-n' 3659acbb460Smrg Run the configure checks, but stop before creating any output 3669acbb460Smrg files. 3679acbb460Smrg 3689acbb460Smrg`configure' also accepts some other, not widely useful, options. Run 3699acbb460Smrg`configure --help' for more details. 3709acbb460Smrg 371
