The following 154f9ac78aSmrgmore-detailed instructions are generic; see the `README' file for 164f9ac78aSmrginstructions specific to this package. 174f9ac78aSmrg 184f9ac78aSmrg The `configure' shell script attempts to guess correct values for 194f9ac78aSmrgvarious system-dependent variables used during compilation. It uses 204f9ac78aSmrgthose values to create a `Makefile' in each directory of the package. 214f9ac78aSmrgIt may also create one or more `.h' files containing system-dependent 224f9ac78aSmrgdefinitions. Finally, it creates a shell script `config.status' that 234f9ac78aSmrgyou can run in the future to recreate the current configuration, and a 244f9ac78aSmrgfile `config.log' containing compiler output (useful mainly for 254f9ac78aSmrgdebugging `configure'). 264f9ac78aSmrg 274f9ac78aSmrg It can also use an optional file (typically called `config.cache' 284f9ac78aSmrgand enabled with `--cache-file=config.cache' or simply `-C') that saves 294f9ac78aSmrgthe results of its tests to speed up reconfiguring. Caching is 304f9ac78aSmrgdisabled by default to prevent problems with accidental use of stale 314f9ac78aSmrgcache files. 324f9ac78aSmrg 334f9ac78aSmrg If you need to do unusual things to compile the package, please try 344f9ac78aSmrgto figure out how `configure' could check whether to do them, and mail 354f9ac78aSmrgdiffs or instructions to the address given in the `README' so they can 364f9ac78aSmrgbe considered for the next release. If you are using the cache, and at 374f9ac78aSmrgsome point `config.cache' contains results you don't want to keep, you 384f9ac78aSmrgmay remove or edit it. 394f9ac78aSmrg 404f9ac78aSmrg The file `configure.ac' (or `configure.in') is used to create 414f9ac78aSmrg`configure' by a program called `autoconf'. You need `configure.ac' if 424f9ac78aSmrgyou want to change it or regenerate `configure' using a newer version 434f9ac78aSmrgof `autoconf'. 444f9ac78aSmrg 454f9ac78aSmrgThe simplest way to compile this package is: 464f9ac78aSmrg 474f9ac78aSmrg 1. `cd' to the directory containing the package's source code and type 484f9ac78aSmrg `./configure' to configure the package for your system. 494f9ac78aSmrg 504f9ac78aSmrg Running `configure' might take a while. While running, it prints 514f9ac78aSmrg some messages telling which features it is checking for. 524f9ac78aSmrg 534f9ac78aSmrg 2. Type `make' to compile the package. 544f9ac78aSmrg 554f9ac78aSmrg 3. Optionally, type `make check' to run any self-tests that come with 564f9ac78aSmrg the package. 574f9ac78aSmrg 584f9ac78aSmrg 4. Type `make install' to install the programs and any data files and 594f9ac78aSmrg documentation. 604f9ac78aSmrg 614f9ac78aSmrg 5. You can remove the program binaries and object files from the 624f9ac78aSmrg source code directory by typing `make clean'. To also remove the 634f9ac78aSmrg files that `configure' created (so you can compile the package for 644f9ac78aSmrg a different kind of computer), type `make distclean'. There is 654f9ac78aSmrg also a `make maintainer-clean' target, but that is intended mainly 664f9ac78aSmrg for the package's developers. If you use it, you may have to get 674f9ac78aSmrg all sorts of other programs in order to regenerate files that came 684f9ac78aSmrg with the distribution. 694f9ac78aSmrg 704f9ac78aSmrg 6. Often, you can also type `make uninstall' to remove the installed 714f9ac78aSmrg files again. 724f9ac78aSmrg 734f9ac78aSmrgCompilers and Options 744f9ac78aSmrg===================== 754f9ac78aSmrg 764f9ac78aSmrg Some systems require unusual options for compilation or linking that 774f9ac78aSmrgthe `configure' script does not know about. Run `./configure --help' 784f9ac78aSmrgfor details on some of the pertinent environment variables. 794f9ac78aSmrg 804f9ac78aSmrg You can give `configure' initial values for configuration parameters 814f9ac78aSmrgby setting variables in the command line or in the environment. Here 824f9ac78aSmrgis an example: 834f9ac78aSmrg 844f9ac78aSmrg ./configure CC=c99 CFLAGS=-g LIBS=-lposix 854f9ac78aSmrg 864f9ac78aSmrg *Note Defining Variables::, for more details. 874f9ac78aSmrg 884f9ac78aSmrgCompiling For Multiple Architectures 894f9ac78aSmrg==================================== 904f9ac78aSmrg 914f9ac78aSmrg You can compile the package for more than one kind of computer at the 924f9ac78aSmrgsame time, by placing the object files for each architecture in their 934f9ac78aSmrgown directory. To do this, you can use GNU `make'. `cd' to the 944f9ac78aSmrgdirectory where you want the object files and executables to go and run 954f9ac78aSmrgthe `configure' script. `configure' automatically checks for the 964f9ac78aSmrgsource code in the directory that `configure' is in and in `..'. 974f9ac78aSmrg 984f9ac78aSmrg With a non-GNU `make', it is safer to compile the package for one 994f9ac78aSmrgarchitecture at a time in the source code directory. After you have 1004f9ac78aSmrginstalled the package for one architecture, use `make distclean' before 1014f9ac78aSmrgreconfiguring for another architecture. 1024f9ac78aSmrg 1034f9ac78aSmrg On MacOS X 10.5 and later systems, you can create libraries and 1044f9ac78aSmrgexecutables that work on multiple system types--known as "fat" or 1054f9ac78aSmrg"universal" binaries--by specifying multiple `-arch' options to the 1064f9ac78aSmrgcompiler but only a single `-arch' option to the preprocessor. Like 1074f9ac78aSmrgthis: 1084f9ac78aSmrg 1094f9ac78aSmrg ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1104f9ac78aSmrg CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 1114f9ac78aSmrg CPP="gcc -E" CXXCPP="g++ -E" 1124f9ac78aSmrg 1134f9ac78aSmrg This is not guaranteed to produce working output in all cases, you 1144f9ac78aSmrgmay have to build one architecture at a time and combine the results 1154f9ac78aSmrgusing the `lipo' tool if you have problems. 1164f9ac78aSmrg 1174f9ac78aSmrgInstallation Names 1184f9ac78aSmrg================== 1194f9ac78aSmrg 1204f9ac78aSmrg By default, `make install' installs the package's commands under 1214f9ac78aSmrg`/usr/local/bin', include files under `/usr/local/include', etc. You 1224f9ac78aSmrgcan specify an installation prefix other than `/usr/local' by giving 1234f9ac78aSmrg`configure' the option `--prefix=PREFIX'. 1244f9ac78aSmrg 1254f9ac78aSmrg You can specify separate installation prefixes for 1264f9ac78aSmrgarchitecture-specific files and architecture-independent files. If you 1274f9ac78aSmrgpass the option `--exec-prefix=PREFIX' to `configure', the package uses 1284f9ac78aSmrgPREFIX as the prefix for installing programs and libraries. 1294f9ac78aSmrgDocumentation and other data files still use the regular prefix. 1304f9ac78aSmrg 1314f9ac78aSmrg In addition, if you use an unusual directory layout you can give 1324f9ac78aSmrgoptions like `--bindir=DIR' to specify different values for particular 1334f9ac78aSmrgkinds of files. Run `configure --help' for a list of the directories 1344f9ac78aSmrgyou can set and what kinds of files go in them. 1354f9ac78aSmrg 1364f9ac78aSmrg If the package supports it, you can cause programs to be installed 1374f9ac78aSmrgwith an extra prefix or suffix on their names by giving `configure' the 1384f9ac78aSmrgoption `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 1394f9ac78aSmrg 1404f9ac78aSmrgOptional Features 1414f9ac78aSmrg================= 1424f9ac78aSmrg 1434f9ac78aSmrg Some packages pay attention to `--enable-FEATURE' options to 1444f9ac78aSmrg`configure', where FEATURE indicates an optional part of the package. 1454f9ac78aSmrgThey may also pay attention to `--with-PACKAGE' options, where PACKAGE 1464f9ac78aSmrgis something like `gnu-as' or `x' (for the X Window System). The 1474f9ac78aSmrg`README' should mention any `--enable-' and `--with-' options that the 1484f9ac78aSmrgpackage recognizes. 1494f9ac78aSmrg 1504f9ac78aSmrg For packages that use the X Window System, `configure' can usually 1514f9ac78aSmrgfind the X include and library files automatically, but if it doesn't, 1524f9ac78aSmrgyou can use the `configure' options `--x-includes=DIR' and 1534f9ac78aSmrg`--x-libraries=DIR' to specify their locations. 1544f9ac78aSmrg 1554f9ac78aSmrgParticular systems 1564f9ac78aSmrg================== 1574f9ac78aSmrg 1584f9ac78aSmrg On HP-UX, the default C compiler is not ANSI C compatible. If GNU 1594f9ac78aSmrgCC is not installed, it is recommended to use the following options in 1604f9ac78aSmrgorder to use an ANSI C compiler: 1614f9ac78aSmrg 1624f9ac78aSmrg ./configure CC="cc -Ae" 1634f9ac78aSmrg 1644f9ac78aSmrgand if that doesn't work, install pre-built binaries of GCC for HP-UX. 1654f9ac78aSmrg 1664f9ac78aSmrg On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 1674f9ac78aSmrgparse its `<wchar.h>' header file. The option `-nodtk' can be used as 1684f9ac78aSmrga workaround. If GNU CC is not installed, it is therefore recommended 1694f9ac78aSmrgto try 1704f9ac78aSmrg 1714f9ac78aSmrg ./configure CC="cc" 1724f9ac78aSmrg 1734f9ac78aSmrgand if that doesn't work, try 1744f9ac78aSmrg 1754f9ac78aSmrg ./configure CC="cc -nodtk" 1764f9ac78aSmrg 1774f9ac78aSmrgSpecifying the System Type 1784f9ac78aSmrg========================== 1794f9ac78aSmrg 1804f9ac78aSmrg There may be some features `configure' cannot figure out 1814f9ac78aSmrgautomatically, but needs to determine by the type of machine the package 1824f9ac78aSmrgwill run on. Usually, assuming the package is built to be run on the 1834f9ac78aSmrg_same_ architectures, `configure' can figure that out, but if it prints 1844f9ac78aSmrga message saying it cannot guess the machine type, give it the 1854f9ac78aSmrg`--build=TYPE' option. TYPE can either be a short name for the system 1864f9ac78aSmrgtype, such as `sun4', or a canonical name which has the form: 1874f9ac78aSmrg 1884f9ac78aSmrg CPU-COMPANY-SYSTEM 1894f9ac78aSmrg 1904f9ac78aSmrgwhere SYSTEM can have one of these forms: 1914f9ac78aSmrg 1924f9ac78aSmrg OS KERNEL-OS 1934f9ac78aSmrg 1944f9ac78aSmrg See the file `config.sub' for the possible values of each field. If 1954f9ac78aSmrg`config.sub' isn't included in this package, then this package doesn't 1964f9ac78aSmrgneed to know the machine type. 1974f9ac78aSmrg 1984f9ac78aSmrg If you are _building_ compiler tools for cross-compiling, you should 1994f9ac78aSmrguse the option `--target=TYPE' to select the type of system they will 2004f9ac78aSmrgproduce code for. 2014f9ac78aSmrg 2024f9ac78aSmrg If you want to _use_ a cross compiler, that generates code for a 2034f9ac78aSmrgplatform different from the build platform, you should specify the 2044f9ac78aSmrg"host" platform (i.e., that on which the generated programs will 2054f9ac78aSmrgeventually be run) with `--host=TYPE'. 2064f9ac78aSmrg 2074f9ac78aSmrgSharing Defaults 2084f9ac78aSmrg================ 2094f9ac78aSmrg 2104f9ac78aSmrg If you want to set default values for `configure' scripts to share, 2114f9ac78aSmrgyou can create a site shell script called `config.site' that gives 2124f9ac78aSmrgdefault values for variables like `CC', `cache_file', and `prefix'. 2134f9ac78aSmrg`configure' looks for `PREFIX/share/config.site' if it exists, then 2144f9ac78aSmrg`PREFIX/etc/config.site' if it exists. Or, you can set the 2154f9ac78aSmrg`CONFIG_SITE' environment variable to the location of the site script. 2164f9ac78aSmrgA warning: not all `configure' scripts look for a site script. 2174f9ac78aSmrg 2184f9ac78aSmrgDefining Variables 2194f9ac78aSmrg================== 2204f9ac78aSmrg 2214f9ac78aSmrg Variables not defined in a site shell script can be set in the 2224f9ac78aSmrgenvironment passed to `configure'. However, some packages may run 2234f9ac78aSmrgconfigure again during the build, and the customized values of these 2244f9ac78aSmrgvariables may be lost. In order to avoid this problem, you should set 2254f9ac78aSmrgthem in the `configure' command line, using `VAR=value'. For example: 2264f9ac78aSmrg 2274f9ac78aSmrg ./configure CC=/usr/local2/bin/gcc 2284f9ac78aSmrg 2294f9ac78aSmrgcauses the specified `gcc' to be used as the C compiler (unless it is 2304f9ac78aSmrgoverridden in the site shell script). 2314f9ac78aSmrg 2324f9ac78aSmrgUnfortunately, this technique does not work for `CONFIG_SHELL' due to 2334f9ac78aSmrgan Autoconf bug. Until the bug is fixed you can use this workaround: 2344f9ac78aSmrg 2354f9ac78aSmrg CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash 2364f9ac78aSmrg 2374f9ac78aSmrg`configure' Invocation 2384f9ac78aSmrg====================== 2394f9ac78aSmrg 2404f9ac78aSmrg `configure' recognizes the following options to control how it 2414f9ac78aSmrgoperates. 2424f9ac78aSmrg 2434f9ac78aSmrg`--help' 2444f9ac78aSmrg`-h' 2454f9ac78aSmrg Print a summary of all of the options to `configure', and exit. 2464f9ac78aSmrg 2474f9ac78aSmrg`--help=short' 2484f9ac78aSmrg`--help=recursive' 2494f9ac78aSmrg Print a summary of the options unique to this package's 2504f9ac78aSmrg `configure', and exit. The `short' variant lists options used 2514f9ac78aSmrg only in the top level, while the `recursive' variant lists options 2524f9ac78aSmrg also present in any nested packages. 2534f9ac78aSmrg 2544f9ac78aSmrg`--version' 2554f9ac78aSmrg`-V' 2564f9ac78aSmrg Print the version of Autoconf used to generate the `configure' 2574f9ac78aSmrg script, and exit. 2584f9ac78aSmrg 2594f9ac78aSmrg`--cache-file=FILE' 2604f9ac78aSmrg Enable the cache: use and save the results of the tests in FILE, 2614f9ac78aSmrg traditionally `config.cache'. FILE defaults to `/dev/null' to 2624f9ac78aSmrg disable caching. 2634f9ac78aSmrg 2644f9ac78aSmrg`--config-cache' 2654f9ac78aSmrg`-C' 2664f9ac78aSmrg Alias for `--cache-file=config.cache'. 2674f9ac78aSmrg 2684f9ac78aSmrg`--quiet' 2694f9ac78aSmrg`--silent' 2704f9ac78aSmrg`-q' 2714f9ac78aSmrg Do not print messages saying which checks are being made. To 2724f9ac78aSmrg suppress all normal output, redirect it to `/dev/null' (any error 2734f9ac78aSmrg messages will still be shown). 2744f9ac78aSmrg 2754f9ac78aSmrg`--srcdir=DIR' 2764f9ac78aSmrg Look for the package's source code in directory DIR. Usually 2774f9ac78aSmrg `configure' can determine that directory automatically. 2784f9ac78aSmrg 2794f9ac78aSmrg`--prefix=DIR' 2804f9ac78aSmrg Use DIR as the installation prefix. *Note Installation Names:: 2814f9ac78aSmrg for more details, including other options available for fine-tuning 2824f9ac78aSmrg the installation locations. 2834f9ac78aSmrg 2844f9ac78aSmrg`--no-create' 2854f9ac78aSmrg`-n' 2864f9ac78aSmrg Run the configure checks, but stop before creating any output 2874f9ac78aSmrg files. 2884f9ac78aSmrg 2894f9ac78aSmrg`configure' also accepts some other, not widely useful, options. Run 2904f9ac78aSmrg`configure --help' for more details. 2914f9ac78aSmrg 292
