The following 172227fc13Smrgmore-detailed instructions are generic; see the `README' file for 187b5fefc8Smrginstructions specific to this package. Some packages provide this 197b5fefc8Smrg`INSTALL' file but do not implement all of the features documented 207b5fefc8Smrgbelow. The lack of an optional feature in a given package is not 217b5fefc8Smrgnecessarily a bug. More recommendations for GNU packages can be found 227b5fefc8Smrgin *note Makefile Conventions: (standards)Makefile Conventions. 232227fc13Smrg 242227fc13Smrg The `configure' shell script attempts to guess correct values for 252227fc13Smrgvarious system-dependent variables used during compilation. It uses 262227fc13Smrgthose values to create a `Makefile' in each directory of the package. 272227fc13SmrgIt may also create one or more `.h' files containing system-dependent 282227fc13Smrgdefinitions. Finally, it creates a shell script `config.status' that 292227fc13Smrgyou can run in the future to recreate the current configuration, and a 302227fc13Smrgfile `config.log' containing compiler output (useful mainly for 312227fc13Smrgdebugging `configure'). 322227fc13Smrg 332227fc13Smrg It can also use an optional file (typically called `config.cache' 342227fc13Smrgand enabled with `--cache-file=config.cache' or simply `-C') that saves 352227fc13Smrgthe results of its tests to speed up reconfiguring. Caching is 362227fc13Smrgdisabled by default to prevent problems with accidental use of stale 372227fc13Smrgcache files. 382227fc13Smrg 392227fc13Smrg If you need to do unusual things to compile the package, please try 402227fc13Smrgto figure out how `configure' could check whether to do them, and mail 412227fc13Smrgdiffs or instructions to the address given in the `README' so they can 422227fc13Smrgbe considered for the next release. If you are using the cache, and at 432227fc13Smrgsome point `config.cache' contains results you don't want to keep, you 442227fc13Smrgmay remove or edit it. 452227fc13Smrg 462227fc13Smrg The file `configure.ac' (or `configure.in') is used to create 472227fc13Smrg`configure' by a program called `autoconf'. You need `configure.ac' if 482227fc13Smrgyou want to change it or regenerate `configure' using a newer version 492227fc13Smrgof `autoconf'. 502227fc13Smrg 517b5fefc8Smrg The simplest way to compile this package is: 522227fc13Smrg 532227fc13Smrg 1. `cd' to the directory containing the package's source code and type 542227fc13Smrg `./configure' to configure the package for your system. 552227fc13Smrg 562227fc13Smrg Running `configure' might take a while. While running, it prints 572227fc13Smrg some messages telling which features it is checking for. 582227fc13Smrg 592227fc13Smrg 2. Type `make' to compile the package. 602227fc13Smrg 612227fc13Smrg 3. Optionally, type `make check' to run any self-tests that come with 627b5fefc8Smrg the package, generally using the just-built uninstalled binaries. 632227fc13Smrg 642227fc13Smrg 4. Type `make install' to install the programs and any data files and 657b5fefc8Smrg documentation. When installing into a prefix owned by root, it is 667b5fefc8Smrg recommended that the package be configured and built as a regular 677b5fefc8Smrg user, and only the `make install' phase executed with root 687b5fefc8Smrg privileges. 697b5fefc8Smrg 707b5fefc8Smrg 5. Optionally, type `make installcheck' to repeat any self-tests, but 717b5fefc8Smrg this time using the binaries in their final installed location. 727b5fefc8Smrg This target does not install anything. Running this target as a 737b5fefc8Smrg regular user, particularly if the prior `make install' required 747b5fefc8Smrg root privileges, verifies that the installation completed 757b5fefc8Smrg correctly. 767b5fefc8Smrg 777b5fefc8Smrg 6. You can remove the program binaries and object files from the 782227fc13Smrg source code directory by typing `make clean'. To also remove the 792227fc13Smrg files that `configure' created (so you can compile the package for 802227fc13Smrg a different kind of computer), type `make distclean'. There is 812227fc13Smrg also a `make maintainer-clean' target, but that is intended mainly 822227fc13Smrg for the package's developers. If you use it, you may have to get 832227fc13Smrg all sorts of other programs in order to regenerate files that came 842227fc13Smrg with the distribution. 852227fc13Smrg 867b5fefc8Smrg 7. Often, you can also type `make uninstall' to remove the installed 877b5fefc8Smrg files again. In practice, not all packages have tested that 887b5fefc8Smrg uninstallation works correctly, even though it is required by the 897b5fefc8Smrg GNU Coding Standards. 907b5fefc8Smrg 917b5fefc8Smrg 8. Some packages, particularly those that use Automake, provide `make 927b5fefc8Smrg distcheck', which can by used by developers to test that all other 937b5fefc8Smrg targets like `make install' and `make uninstall' work correctly. 947b5fefc8Smrg This target is generally not run by end users. 952227fc13Smrg 962227fc13SmrgCompilers and Options 972227fc13Smrg===================== 982227fc13Smrg 992227fc13Smrg Some systems require unusual options for compilation or linking that 1002227fc13Smrgthe `configure' script does not know about. Run `./configure --help' 1012227fc13Smrgfor details on some of the pertinent environment variables. 1022227fc13Smrg 1032227fc13Smrg You can give `configure' initial values for configuration parameters 1042227fc13Smrgby setting variables in the command line or in the environment. Here 1052227fc13Smrgis an example: 1062227fc13Smrg 1072227fc13Smrg ./configure CC=c99 CFLAGS=-g LIBS=-lposix 1082227fc13Smrg 1092227fc13Smrg *Note Defining Variables::, for more details. 1102227fc13Smrg 1112227fc13SmrgCompiling For Multiple Architectures 1122227fc13Smrg==================================== 1132227fc13Smrg 1142227fc13Smrg You can compile the package for more than one kind of computer at the 1152227fc13Smrgsame time, by placing the object files for each architecture in their 1162227fc13Smrgown directory. To do this, you can use GNU `make'. `cd' to the 1172227fc13Smrgdirectory where you want the object files and executables to go and run 1182227fc13Smrgthe `configure' script. `configure' automatically checks for the 1197b5fefc8Smrgsource code in the directory that `configure' is in and in `..'. This 1207b5fefc8Smrgis known as a "VPATH" build. 1212227fc13Smrg 1222227fc13Smrg With a non-GNU `make', it is safer to compile the package for one 1232227fc13Smrgarchitecture at a time in the source code directory. After you have 1242227fc13Smrginstalled the package for one architecture, use `make distclean' before 1252227fc13Smrgreconfiguring for another architecture. 1262227fc13Smrg 1272227fc13Smrg On MacOS X 10.5 and later systems, you can create libraries and 1282227fc13Smrgexecutables that work on multiple system types--known as "fat" or 1292227fc13Smrg"universal" binaries--by specifying multiple `-arch' options to the 1302227fc13Smrgcompiler but only a single `-arch' option to the preprocessor. Like 1312227fc13Smrgthis: 1322227fc13Smrg 1332227fc13Smrg ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1342227fc13Smrg CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1352227fc13Smrg CPP="gcc -E" CXXCPP="g++ -E" 1362227fc13Smrg 1372227fc13Smrg This is not guaranteed to produce working output in all cases, you 1382227fc13Smrgmay have to build one architecture at a time and combine the results 1392227fc13Smrgusing the `lipo' tool if you have problems. 1402227fc13Smrg 1412227fc13SmrgInstallation Names 1422227fc13Smrg================== 1432227fc13Smrg 1442227fc13Smrg By default, `make install' installs the package's commands under 1452227fc13Smrg`/usr/local/bin', include files under `/usr/local/include', etc. You 1462227fc13Smrgcan specify an installation prefix other than `/usr/local' by giving 1477b5fefc8Smrg`configure' the option `--prefix=PREFIX', where PREFIX must be an 1487b5fefc8Smrgabsolute file name. 1492227fc13Smrg 1502227fc13Smrg You can specify separate installation prefixes for 1512227fc13Smrgarchitecture-specific files and architecture-independent files. If you 1522227fc13Smrgpass the option `--exec-prefix=PREFIX' to `configure', the package uses 1532227fc13SmrgPREFIX as the prefix for installing programs and libraries. 1542227fc13SmrgDocumentation and other data files still use the regular prefix. 1552227fc13Smrg 1562227fc13Smrg In addition, if you use an unusual directory layout you can give 1572227fc13Smrgoptions like `--bindir=DIR' to specify different values for particular 1582227fc13Smrgkinds of files. Run `configure --help' for a list of the directories 1597b5fefc8Smrgyou can set and what kinds of files go in them. In general, the 1607b5fefc8Smrgdefault for these options is expressed in terms of `${prefix}', so that 1617b5fefc8Smrgspecifying just `--prefix' will affect all of the other directory 1627b5fefc8Smrgspecifications that were not explicitly provided. 1637b5fefc8Smrg 1647b5fefc8Smrg The most portable way to affect installation locations is to pass the 1657b5fefc8Smrgcorrect locations to `configure'; however, many packages provide one or 1667b5fefc8Smrgboth of the following shortcuts of passing variable assignments to the 1677b5fefc8Smrg`make install' command line to change installation locations without 1687b5fefc8Smrghaving to reconfigure or recompile. 1697b5fefc8Smrg 1707b5fefc8Smrg The first method involves providing an override variable for each 1717b5fefc8Smrgaffected directory. For example, `make install 1727b5fefc8Smrgprefix=/alternate/directory' will choose an alternate location for all 1737b5fefc8Smrgdirectory configuration variables that were expressed in terms of 1747b5fefc8Smrg`${prefix}'. Any directories that were specified during `configure', 1757b5fefc8Smrgbut not in terms of `${prefix}', must each be overridden at install 1767b5fefc8Smrgtime for the entire installation to be relocated. The approach of 1777b5fefc8Smrgmakefile variable overrides for each directory variable is required by 1787b5fefc8Smrgthe GNU Coding Standards, and ideally causes no recompilation. 1797b5fefc8SmrgHowever, some platforms have known limitations with the semantics of 1807b5fefc8Smrgshared libraries that end up requiring recompilation when using this 1817b5fefc8Smrgmethod, particularly noticeable in packages that use GNU Libtool. 1827b5fefc8Smrg 1837b5fefc8Smrg The second method involves providing the `DESTDIR' variable. For 1847b5fefc8Smrgexample, `make install DESTDIR=/alternate/directory' will prepend 1857b5fefc8Smrg`/alternate/directory' before all installation names. The approach of 1867b5fefc8Smrg`DESTDIR' overrides is not required by the GNU Coding Standards, and 1877b5fefc8Smrgdoes not work on platforms that have drive letters. On the other hand, 1887b5fefc8Smrgit does better at avoiding recompilation issues, and works well even 1897b5fefc8Smrgwhen some directory options were not specified in terms of `${prefix}' 1907b5fefc8Smrgat `configure' time. 1917b5fefc8Smrg 1927b5fefc8SmrgOptional Features 1937b5fefc8Smrg================= 1942227fc13Smrg 1952227fc13Smrg If the package supports it, you can cause programs to be installed 1962227fc13Smrgwith an extra prefix or suffix on their names by giving `configure' the 1972227fc13Smrgoption `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 1982227fc13Smrg 1992227fc13Smrg Some packages pay attention to `--enable-FEATURE' options to 2002227fc13Smrg`configure', where FEATURE indicates an optional part of the package. 2012227fc13SmrgThey may also pay attention to `--with-PACKAGE' options, where PACKAGE 2022227fc13Smrgis something like `gnu-as' or `x' (for the X Window System). The 2032227fc13Smrg`README' should mention any `--enable-' and `--with-' options that the 2042227fc13Smrgpackage recognizes. 2052227fc13Smrg 2062227fc13Smrg For packages that use the X Window System, `configure' can usually 2072227fc13Smrgfind the X include and library files automatically, but if it doesn't, 2082227fc13Smrgyou can use the `configure' options `--x-includes=DIR' and 2092227fc13Smrg`--x-libraries=DIR' to specify their locations. 2102227fc13Smrg 2117b5fefc8Smrg Some packages offer the ability to configure how verbose the 2127b5fefc8Smrgexecution of `make' will be. For these packages, running `./configure 2137b5fefc8Smrg--enable-silent-rules' sets the default to minimal output, which can be 2147b5fefc8Smrgoverridden with `make V=1'; while running `./configure 2157b5fefc8Smrg--disable-silent-rules' sets the default to verbose, which can be 2167b5fefc8Smrgoverridden with `make V=0'. 2177b5fefc8Smrg 2182227fc13SmrgParticular systems 2192227fc13Smrg================== 2202227fc13Smrg 2212227fc13Smrg On HP-UX, the default C compiler is not ANSI C compatible. If GNU 2222227fc13SmrgCC is not installed, it is recommended to use the following options in 2232227fc13Smrgorder to use an ANSI C compiler: 2242227fc13Smrg 2257b5fefc8Smrg ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" 2262227fc13Smrg 2272227fc13Smrgand if that doesn't work, install pre-built binaries of GCC for HP-UX. 2282227fc13Smrg 2297b5fefc8Smrg HP-UX `make' updates targets which have the same time stamps as 2307b5fefc8Smrgtheir prerequisites, which makes it generally unusable when shipped 2317b5fefc8Smrggenerated files such as `configure' are involved. Use GNU `make' 2327b5fefc8Smrginstead. 2337b5fefc8Smrg 2342227fc13Smrg On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 2352227fc13Smrgparse its `<wchar.h>' header file. The option `-nodtk' can be used as 2362227fc13Smrga workaround. If GNU CC is not installed, it is therefore recommended 2372227fc13Smrgto try 2382227fc13Smrg 2392227fc13Smrg ./configure CC="cc" 2402227fc13Smrg 2412227fc13Smrgand if that doesn't work, try 2422227fc13Smrg 2432227fc13Smrg ./configure CC="cc -nodtk" 2442227fc13Smrg 2457b5fefc8Smrg On Solaris, don't put `/usr/ucb' early in your `PATH'. This 2467b5fefc8Smrgdirectory contains several dysfunctional programs; working variants of 2477b5fefc8Smrgthese programs are available in `/usr/bin'. So, if you need `/usr/ucb' 2487b5fefc8Smrgin your `PATH', put it _after_ `/usr/bin'. 2497b5fefc8Smrg 2507b5fefc8Smrg On Haiku, software installed for all users goes in `/boot/common', 2517b5fefc8Smrgnot `/usr/local'. It is recommended to use the following options: 2527b5fefc8Smrg 2537b5fefc8Smrg ./configure --prefix=/boot/common 2547b5fefc8Smrg 2552227fc13SmrgSpecifying the System Type 2562227fc13Smrg========================== 2572227fc13Smrg 2582227fc13Smrg There may be some features `configure' cannot figure out 2592227fc13Smrgautomatically, but needs to determine by the type of machine the package 2602227fc13Smrgwill run on. Usually, assuming the package is built to be run on the 2612227fc13Smrg_same_ architectures, `configure' can figure that out, but if it prints 2622227fc13Smrga message saying it cannot guess the machine type, give it the 2632227fc13Smrg`--build=TYPE' option. TYPE can either be a short name for the system 2642227fc13Smrgtype, such as `sun4', or a canonical name which has the form: 2652227fc13Smrg 2662227fc13Smrg CPU-COMPANY-SYSTEM 2672227fc13Smrg 2682227fc13Smrgwhere SYSTEM can have one of these forms: 2692227fc13Smrg 2707b5fefc8Smrg OS 2717b5fefc8Smrg KERNEL-OS 2722227fc13Smrg 2732227fc13Smrg See the file `config.sub' for the possible values of each field. If 2742227fc13Smrg`config.sub' isn't included in this package, then this package doesn't 2752227fc13Smrgneed to know the machine type. 2762227fc13Smrg 2772227fc13Smrg If you are _building_ compiler tools for cross-compiling, you should 2782227fc13Smrguse the option `--target=TYPE' to select the type of system they will 2792227fc13Smrgproduce code for. 2802227fc13Smrg 2812227fc13Smrg If you want to _use_ a cross compiler, that generates code for a 2822227fc13Smrgplatform different from the build platform, you should specify the 2832227fc13Smrg"host" platform (i.e., that on which the generated programs will 2842227fc13Smrgeventually be run) with `--host=TYPE'. 2852227fc13Smrg 2862227fc13SmrgSharing Defaults 2872227fc13Smrg================ 2882227fc13Smrg 2892227fc13Smrg If you want to set default values for `configure' scripts to share, 2902227fc13Smrgyou can create a site shell script called `config.site' that gives 2912227fc13Smrgdefault values for variables like `CC', `cache_file', and `prefix'. 2922227fc13Smrg`configure' looks for `PREFIX/share/config.site' if it exists, then 2932227fc13Smrg`PREFIX/etc/config.site' if it exists. Or, you can set the 2942227fc13Smrg`CONFIG_SITE' environment variable to the location of the site script. 2952227fc13SmrgA warning: not all `configure' scripts look for a site script. 2962227fc13Smrg 2972227fc13SmrgDefining Variables 2982227fc13Smrg================== 2992227fc13Smrg 3002227fc13Smrg Variables not defined in a site shell script can be set in the 3012227fc13Smrgenvironment passed to `configure'. However, some packages may run 3022227fc13Smrgconfigure again during the build, and the customized values of these 3032227fc13Smrgvariables may be lost. In order to avoid this problem, you should set 3042227fc13Smrgthem in the `configure' command line, using `VAR=value'. For example: 3052227fc13Smrg 3062227fc13Smrg ./configure CC=/usr/local2/bin/gcc 3072227fc13Smrg 3082227fc13Smrgcauses the specified `gcc' to be used as the C compiler (unless it is 3092227fc13Smrgoverridden in the site shell script). 3102227fc13Smrg 3112227fc13SmrgUnfortunately, this technique does not work for `CONFIG_SHELL' due to 3122227fc13Smrgan Autoconf bug. Until the bug is fixed you can use this workaround: 3132227fc13Smrg 3142227fc13Smrg CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash 3152227fc13Smrg 3162227fc13Smrg`configure' Invocation 3172227fc13Smrg====================== 3182227fc13Smrg 3192227fc13Smrg `configure' recognizes the following options to control how it 3202227fc13Smrgoperates. 3212227fc13Smrg 3222227fc13Smrg`--help' 3232227fc13Smrg`-h' 3242227fc13Smrg Print a summary of all of the options to `configure', and exit. 3252227fc13Smrg 3262227fc13Smrg`--help=short' 3272227fc13Smrg`--help=recursive' 3282227fc13Smrg Print a summary of the options unique to this package's 3292227fc13Smrg `configure', and exit. The `short' variant lists options used 3302227fc13Smrg only in the top level, while the `recursive' variant lists options 3312227fc13Smrg also present in any nested packages. 3322227fc13Smrg 3332227fc13Smrg`--version' 3342227fc13Smrg`-V' 3352227fc13Smrg Print the version of Autoconf used to generate the `configure' 3362227fc13Smrg script, and exit. 3372227fc13Smrg 3382227fc13Smrg`--cache-file=FILE' 3392227fc13Smrg Enable the cache: use and save the results of the tests in FILE, 3402227fc13Smrg traditionally `config.cache'. FILE defaults to `/dev/null' to 3412227fc13Smrg disable caching. 3422227fc13Smrg 3432227fc13Smrg`--config-cache' 3442227fc13Smrg`-C' 3452227fc13Smrg Alias for `--cache-file=config.cache'. 3462227fc13Smrg 3472227fc13Smrg`--quiet' 3482227fc13Smrg`--silent' 3492227fc13Smrg`-q' 3502227fc13Smrg Do not print messages saying which checks are being made. To 3512227fc13Smrg suppress all normal output, redirect it to `/dev/null' (any error 3522227fc13Smrg messages will still be shown). 3532227fc13Smrg 3542227fc13Smrg`--srcdir=DIR' 3552227fc13Smrg Look for the package's source code in directory DIR. Usually 3562227fc13Smrg `configure' can determine that directory automatically. 3572227fc13Smrg 3582227fc13Smrg`--prefix=DIR' 3597b5fefc8Smrg Use DIR as the installation prefix. *note Installation Names:: 3602227fc13Smrg for more details, including other options available for fine-tuning 3612227fc13Smrg the installation locations. 3622227fc13Smrg 3632227fc13Smrg`--no-create' 3642227fc13Smrg`-n' 3652227fc13Smrg Run the configure checks, but stop before creating any output 3662227fc13Smrg files. 3672227fc13Smrg 3682227fc13Smrg`configure' also accepts some other, not widely useful, options. Run 3692227fc13Smrg`configure --help' for more details. 3702227fc13Smrg 371
