The following 17b5d2086dSmrgmore-detailed instructions are generic; see the `README' file for 1818eba588Smrginstructions specific to this package. Some packages provide this 1918eba588Smrg`INSTALL' file but do not implement all of the features documented 2018eba588Smrgbelow. The lack of an optional feature in a given package is not 2118eba588Smrgnecessarily a bug. More recommendations for GNU packages can be found 2218eba588Smrgin *note Makefile Conventions: (standards)Makefile Conventions. 23b5d2086dSmrg 24b5d2086dSmrg The `configure' shell script attempts to guess correct values for 25b5d2086dSmrgvarious system-dependent variables used during compilation. It uses 26b5d2086dSmrgthose values to create a `Makefile' in each directory of the package. 27b5d2086dSmrgIt may also create one or more `.h' files containing system-dependent 28b5d2086dSmrgdefinitions. Finally, it creates a shell script `config.status' that 29b5d2086dSmrgyou can run in the future to recreate the current configuration, and a 30b5d2086dSmrgfile `config.log' containing compiler output (useful mainly for 31b5d2086dSmrgdebugging `configure'). 32b5d2086dSmrg 33b5d2086dSmrg It can also use an optional file (typically called `config.cache' 34b5d2086dSmrgand enabled with `--cache-file=config.cache' or simply `-C') that saves 35b5d2086dSmrgthe results of its tests to speed up reconfiguring. Caching is 36b5d2086dSmrgdisabled by default to prevent problems with accidental use of stale 37b5d2086dSmrgcache files. 38b5d2086dSmrg 39b5d2086dSmrg If you need to do unusual things to compile the package, please try 40b5d2086dSmrgto figure out how `configure' could check whether to do them, and mail 41b5d2086dSmrgdiffs or instructions to the address given in the `README' so they can 42b5d2086dSmrgbe considered for the next release. If you are using the cache, and at 43b5d2086dSmrgsome point `config.cache' contains results you don't want to keep, you 44b5d2086dSmrgmay remove or edit it. 45b5d2086dSmrg 46b5d2086dSmrg The file `configure.ac' (or `configure.in') is used to create 47b5d2086dSmrg`configure' by a program called `autoconf'. You need `configure.ac' if 48b5d2086dSmrgyou want to change it or regenerate `configure' using a newer version 49b5d2086dSmrgof `autoconf'. 50b5d2086dSmrg 5118eba588Smrg The simplest way to compile this package is: 52b5d2086dSmrg 53b5d2086dSmrg 1. `cd' to the directory containing the package's source code and type 54b5d2086dSmrg `./configure' to configure the package for your system. 55b5d2086dSmrg 56b5d2086dSmrg Running `configure' might take a while. While running, it prints 57b5d2086dSmrg some messages telling which features it is checking for. 58b5d2086dSmrg 59b5d2086dSmrg 2. Type `make' to compile the package. 60b5d2086dSmrg 61b5d2086dSmrg 3. Optionally, type `make check' to run any self-tests that come with 6218eba588Smrg the package, generally using the just-built uninstalled binaries. 63b5d2086dSmrg 64b5d2086dSmrg 4. Type `make install' to install the programs and any data files and 6518eba588Smrg documentation. When installing into a prefix owned by root, it is 6618eba588Smrg recommended that the package be configured and built as a regular 6718eba588Smrg user, and only the `make install' phase executed with root 6818eba588Smrg privileges. 6918eba588Smrg 7018eba588Smrg 5. Optionally, type `make installcheck' to repeat any self-tests, but 7118eba588Smrg this time using the binaries in their final installed location. 7218eba588Smrg This target does not install anything. Running this target as a 7318eba588Smrg regular user, particularly if the prior `make install' required 7418eba588Smrg root privileges, verifies that the installation completed 7518eba588Smrg correctly. 7618eba588Smrg 7718eba588Smrg 6. You can remove the program binaries and object files from the 78b5d2086dSmrg source code directory by typing `make clean'. To also remove the 79b5d2086dSmrg files that `configure' created (so you can compile the package for 80b5d2086dSmrg a different kind of computer), type `make distclean'. There is 81b5d2086dSmrg also a `make maintainer-clean' target, but that is intended mainly 82b5d2086dSmrg for the package's developers. If you use it, you may have to get 83b5d2086dSmrg all sorts of other programs in order to regenerate files that came 84b5d2086dSmrg with the distribution. 85b5d2086dSmrg 8618eba588Smrg 7. Often, you can also type `make uninstall' to remove the installed 8718eba588Smrg files again. In practice, not all packages have tested that 8818eba588Smrg uninstallation works correctly, even though it is required by the 8918eba588Smrg GNU Coding Standards. 9018eba588Smrg 9118eba588Smrg 8. Some packages, particularly those that use Automake, provide `make 9218eba588Smrg distcheck', which can by used by developers to test that all other 9318eba588Smrg targets like `make install' and `make uninstall' work correctly. 9418eba588Smrg This target is generally not run by end users. 95b5d2086dSmrg 96b5d2086dSmrgCompilers and Options 97b5d2086dSmrg===================== 98b5d2086dSmrg 99b5d2086dSmrg Some systems require unusual options for compilation or linking that 100b5d2086dSmrgthe `configure' script does not know about. Run `./configure --help' 101b5d2086dSmrgfor details on some of the pertinent environment variables. 102b5d2086dSmrg 103b5d2086dSmrg You can give `configure' initial values for configuration parameters 104b5d2086dSmrgby setting variables in the command line or in the environment. Here 105b5d2086dSmrgis an example: 106b5d2086dSmrg 107b5d2086dSmrg ./configure CC=c99 CFLAGS=-g LIBS=-lposix 108b5d2086dSmrg 109b5d2086dSmrg *Note Defining Variables::, for more details. 110b5d2086dSmrg 111b5d2086dSmrgCompiling For Multiple Architectures 112b5d2086dSmrg==================================== 113b5d2086dSmrg 114b5d2086dSmrg You can compile the package for more than one kind of computer at the 115b5d2086dSmrgsame time, by placing the object files for each architecture in their 116b5d2086dSmrgown directory. To do this, you can use GNU `make'. `cd' to the 117b5d2086dSmrgdirectory where you want the object files and executables to go and run 118b5d2086dSmrgthe `configure' script. `configure' automatically checks for the 11918eba588Smrgsource code in the directory that `configure' is in and in `..'. This 12018eba588Smrgis known as a "VPATH" build. 121b5d2086dSmrg 122b5d2086dSmrg With a non-GNU `make', it is safer to compile the package for one 123b5d2086dSmrgarchitecture at a time in the source code directory. After you have 124b5d2086dSmrginstalled the package for one architecture, use `make distclean' before 125b5d2086dSmrgreconfiguring for another architecture. 126b5d2086dSmrg 127b5d2086dSmrg On MacOS X 10.5 and later systems, you can create libraries and 128b5d2086dSmrgexecutables that work on multiple system types--known as "fat" or 129b5d2086dSmrg"universal" binaries--by specifying multiple `-arch' options to the 130b5d2086dSmrgcompiler but only a single `-arch' option to the preprocessor. Like 131b5d2086dSmrgthis: 132b5d2086dSmrg 133b5d2086dSmrg ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 134b5d2086dSmrg CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 135b5d2086dSmrg CPP="gcc -E" CXXCPP="g++ -E" 136b5d2086dSmrg 137b5d2086dSmrg This is not guaranteed to produce working output in all cases, you 138b5d2086dSmrgmay have to build one architecture at a time and combine the results 139b5d2086dSmrgusing the `lipo' tool if you have problems. 140b5d2086dSmrg 141b5d2086dSmrgInstallation Names 142b5d2086dSmrg================== 143b5d2086dSmrg 144b5d2086dSmrg By default, `make install' installs the package's commands under 145b5d2086dSmrg`/usr/local/bin', include files under `/usr/local/include', etc. You 146b5d2086dSmrgcan specify an installation prefix other than `/usr/local' by giving 14718eba588Smrg`configure' the option `--prefix=PREFIX', where PREFIX must be an 14818eba588Smrgabsolute file name. 149b5d2086dSmrg 150b5d2086dSmrg You can specify separate installation prefixes for 151b5d2086dSmrgarchitecture-specific files and architecture-independent files. If you 152b5d2086dSmrgpass the option `--exec-prefix=PREFIX' to `configure', the package uses 153b5d2086dSmrgPREFIX as the prefix for installing programs and libraries. 154b5d2086dSmrgDocumentation and other data files still use the regular prefix. 155b5d2086dSmrg 156b5d2086dSmrg In addition, if you use an unusual directory layout you can give 157b5d2086dSmrgoptions like `--bindir=DIR' to specify different values for particular 158b5d2086dSmrgkinds of files. Run `configure --help' for a list of the directories 15918eba588Smrgyou can set and what kinds of files go in them. In general, the 16018eba588Smrgdefault for these options is expressed in terms of `${prefix}', so that 16118eba588Smrgspecifying just `--prefix' will affect all of the other directory 16218eba588Smrgspecifications that were not explicitly provided. 16318eba588Smrg 16418eba588Smrg The most portable way to affect installation locations is to pass the 16518eba588Smrgcorrect locations to `configure'; however, many packages provide one or 16618eba588Smrgboth of the following shortcuts of passing variable assignments to the 16718eba588Smrg`make install' command line to change installation locations without 16818eba588Smrghaving to reconfigure or recompile. 16918eba588Smrg 17018eba588Smrg The first method involves providing an override variable for each 17118eba588Smrgaffected directory. For example, `make install 17218eba588Smrgprefix=/alternate/directory' will choose an alternate location for all 17318eba588Smrgdirectory configuration variables that were expressed in terms of 17418eba588Smrg`${prefix}'. Any directories that were specified during `configure', 17518eba588Smrgbut not in terms of `${prefix}', must each be overridden at install 17618eba588Smrgtime for the entire installation to be relocated. The approach of 17718eba588Smrgmakefile variable overrides for each directory variable is required by 17818eba588Smrgthe GNU Coding Standards, and ideally causes no recompilation. 17918eba588SmrgHowever, some platforms have known limitations with the semantics of 18018eba588Smrgshared libraries that end up requiring recompilation when using this 18118eba588Smrgmethod, particularly noticeable in packages that use GNU Libtool. 18218eba588Smrg 18318eba588Smrg The second method involves providing the `DESTDIR' variable. For 18418eba588Smrgexample, `make install DESTDIR=/alternate/directory' will prepend 18518eba588Smrg`/alternate/directory' before all installation names. The approach of 18618eba588Smrg`DESTDIR' overrides is not required by the GNU Coding Standards, and 18718eba588Smrgdoes not work on platforms that have drive letters. On the other hand, 18818eba588Smrgit does better at avoiding recompilation issues, and works well even 18918eba588Smrgwhen some directory options were not specified in terms of `${prefix}' 19018eba588Smrgat `configure' time. 19118eba588Smrg 19218eba588SmrgOptional Features 19318eba588Smrg================= 194b5d2086dSmrg 195b5d2086dSmrg If the package supports it, you can cause programs to be installed 196b5d2086dSmrgwith an extra prefix or suffix on their names by giving `configure' the 197b5d2086dSmrgoption `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 198b5d2086dSmrg 199b5d2086dSmrg Some packages pay attention to `--enable-FEATURE' options to 200b5d2086dSmrg`configure', where FEATURE indicates an optional part of the package. 201b5d2086dSmrgThey may also pay attention to `--with-PACKAGE' options, where PACKAGE 202b5d2086dSmrgis something like `gnu-as' or `x' (for the X Window System). The 203b5d2086dSmrg`README' should mention any `--enable-' and `--with-' options that the 204b5d2086dSmrgpackage recognizes. 205b5d2086dSmrg 206b5d2086dSmrg For packages that use the X Window System, `configure' can usually 207b5d2086dSmrgfind the X include and library files automatically, but if it doesn't, 208b5d2086dSmrgyou can use the `configure' options `--x-includes=DIR' and 209b5d2086dSmrg`--x-libraries=DIR' to specify their locations. 210b5d2086dSmrg 21118eba588Smrg Some packages offer the ability to configure how verbose the 21218eba588Smrgexecution of `make' will be. For these packages, running `./configure 21318eba588Smrg--enable-silent-rules' sets the default to minimal output, which can be 21418eba588Smrgoverridden with `make V=1'; while running `./configure 21518eba588Smrg--disable-silent-rules' sets the default to verbose, which can be 21618eba588Smrgoverridden with `make V=0'. 21718eba588Smrg 218b5d2086dSmrgParticular systems 219b5d2086dSmrg================== 220b5d2086dSmrg 221b5d2086dSmrg On HP-UX, the default C compiler is not ANSI C compatible. If GNU 222b5d2086dSmrgCC is not installed, it is recommended to use the following options in 223b5d2086dSmrgorder to use an ANSI C compiler: 224b5d2086dSmrg 22518eba588Smrg ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" 226b5d2086dSmrg 227b5d2086dSmrgand if that doesn't work, install pre-built binaries of GCC for HP-UX. 228b5d2086dSmrg 22918eba588Smrg HP-UX `make' updates targets which have the same time stamps as 23018eba588Smrgtheir prerequisites, which makes it generally unusable when shipped 23118eba588Smrggenerated files such as `configure' are involved. Use GNU `make' 23218eba588Smrginstead. 23318eba588Smrg 234b5d2086dSmrg On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 235b5d2086dSmrgparse its `<wchar.h>' header file. The option `-nodtk' can be used as 236b5d2086dSmrga workaround. If GNU CC is not installed, it is therefore recommended 237b5d2086dSmrgto try 238b5d2086dSmrg 239b5d2086dSmrg ./configure CC="cc" 240b5d2086dSmrg 241b5d2086dSmrgand if that doesn't work, try 242b5d2086dSmrg 243b5d2086dSmrg ./configure CC="cc -nodtk" 244b5d2086dSmrg 24518eba588Smrg On Solaris, don't put `/usr/ucb' early in your `PATH'. This 24618eba588Smrgdirectory contains several dysfunctional programs; working variants of 24718eba588Smrgthese programs are available in `/usr/bin'. So, if you need `/usr/ucb' 24818eba588Smrgin your `PATH', put it _after_ `/usr/bin'. 24918eba588Smrg 25018eba588Smrg On Haiku, software installed for all users goes in `/boot/common', 25118eba588Smrgnot `/usr/local'. It is recommended to use the following options: 25218eba588Smrg 25318eba588Smrg ./configure --prefix=/boot/common 25418eba588Smrg 255b5d2086dSmrgSpecifying the System Type 256b5d2086dSmrg========================== 257b5d2086dSmrg 258b5d2086dSmrg There may be some features `configure' cannot figure out 259b5d2086dSmrgautomatically, but needs to determine by the type of machine the package 260b5d2086dSmrgwill run on. Usually, assuming the package is built to be run on the 261b5d2086dSmrg_same_ architectures, `configure' can figure that out, but if it prints 262b5d2086dSmrga message saying it cannot guess the machine type, give it the 263b5d2086dSmrg`--build=TYPE' option. TYPE can either be a short name for the system 264b5d2086dSmrgtype, such as `sun4', or a canonical name which has the form: 265b5d2086dSmrg 266b5d2086dSmrg CPU-COMPANY-SYSTEM 267b5d2086dSmrg 268b5d2086dSmrgwhere SYSTEM can have one of these forms: 269b5d2086dSmrg 27018eba588Smrg OS 27118eba588Smrg KERNEL-OS 272b5d2086dSmrg 273b5d2086dSmrg See the file `config.sub' for the possible values of each field. If 274b5d2086dSmrg`config.sub' isn't included in this package, then this package doesn't 275b5d2086dSmrgneed to know the machine type. 276b5d2086dSmrg 277b5d2086dSmrg If you are _building_ compiler tools for cross-compiling, you should 278b5d2086dSmrguse the option `--target=TYPE' to select the type of system they will 279b5d2086dSmrgproduce code for. 280b5d2086dSmrg 281b5d2086dSmrg If you want to _use_ a cross compiler, that generates code for a 282b5d2086dSmrgplatform different from the build platform, you should specify the 283b5d2086dSmrg"host" platform (i.e., that on which the generated programs will 284b5d2086dSmrgeventually be run) with `--host=TYPE'. 285b5d2086dSmrg 286b5d2086dSmrgSharing Defaults 287b5d2086dSmrg================ 288b5d2086dSmrg 289b5d2086dSmrg If you want to set default values for `configure' scripts to share, 290b5d2086dSmrgyou can create a site shell script called `config.site' that gives 291b5d2086dSmrgdefault values for variables like `CC', `cache_file', and `prefix'. 292b5d2086dSmrg`configure' looks for `PREFIX/share/config.site' if it exists, then 293b5d2086dSmrg`PREFIX/etc/config.site' if it exists. Or, you can set the 294b5d2086dSmrg`CONFIG_SITE' environment variable to the location of the site script. 295b5d2086dSmrgA warning: not all `configure' scripts look for a site script. 296b5d2086dSmrg 297b5d2086dSmrgDefining Variables 298b5d2086dSmrg================== 299b5d2086dSmrg 300b5d2086dSmrg Variables not defined in a site shell script can be set in the 301b5d2086dSmrgenvironment passed to `configure'. However, some packages may run 302b5d2086dSmrgconfigure again during the build, and the customized values of these 303b5d2086dSmrgvariables may be lost. In order to avoid this problem, you should set 304b5d2086dSmrgthem in the `configure' command line, using `VAR=value'. For example: 305b5d2086dSmrg 306b5d2086dSmrg ./configure CC=/usr/local2/bin/gcc 307b5d2086dSmrg 308b5d2086dSmrgcauses the specified `gcc' to be used as the C compiler (unless it is 309b5d2086dSmrgoverridden in the site shell script). 310b5d2086dSmrg 311b5d2086dSmrgUnfortunately, this technique does not work for `CONFIG_SHELL' due to 312b5d2086dSmrgan Autoconf bug. Until the bug is fixed you can use this workaround: 313b5d2086dSmrg 314b5d2086dSmrg CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash 315b5d2086dSmrg 316b5d2086dSmrg`configure' Invocation 317b5d2086dSmrg====================== 318b5d2086dSmrg 319b5d2086dSmrg `configure' recognizes the following options to control how it 320b5d2086dSmrgoperates. 321b5d2086dSmrg 322b5d2086dSmrg`--help' 323b5d2086dSmrg`-h' 324b5d2086dSmrg Print a summary of all of the options to `configure', and exit. 325b5d2086dSmrg 326b5d2086dSmrg`--help=short' 327b5d2086dSmrg`--help=recursive' 328b5d2086dSmrg Print a summary of the options unique to this package's 329b5d2086dSmrg `configure', and exit. The `short' variant lists options used 330b5d2086dSmrg only in the top level, while the `recursive' variant lists options 331b5d2086dSmrg also present in any nested packages. 332b5d2086dSmrg 333b5d2086dSmrg`--version' 334b5d2086dSmrg`-V' 335b5d2086dSmrg Print the version of Autoconf used to generate the `configure' 336b5d2086dSmrg script, and exit. 337b5d2086dSmrg 338b5d2086dSmrg`--cache-file=FILE' 339b5d2086dSmrg Enable the cache: use and save the results of the tests in FILE, 340b5d2086dSmrg traditionally `config.cache'.
