They are listed in +the file ‘DEPENDENCIES’. It is recommended to install the listed +packages before installing this package. + +Basic Installation +================== + + Briefly, the shell commands ‘./configure; make; make install’ should +configure, build, and install this package. The following +more-detailed instructions are generic; see the ‘README’ file for +instructions specific to this package. + + The ‘configure’ shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a ‘Makefile’ in each directory of the package. +It may also create one or more ‘.h’ files containing system-dependent +definitions. Finally, it creates a shell script ‘config.status’ that +you can run in the future to recreate the current configuration, and a +file ‘config.log’ containing compiler output (useful mainly for +debugging ‘configure’). + + It can also use an optional file (typically called ‘config.cache’ +and enabled with ‘--cache-file=config.cache’ or simply ‘-C’) that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how ‘configure’ could check whether to do them, and mail +diffs or instructions to the address given in the ‘README’ so they can +be considered for the next release. If you are using the cache, and at +some point ‘config.cache’ contains results you don't want to keep, you +may remove or edit it. + + The file ‘configure.ac’ (or ‘configure.in’) is used to create +‘configure’ by a program called ‘autoconf’. You need ‘configure.ac’ if +you want to change it or regenerate ‘configure’ using a newer version +of ‘autoconf’. + +The simplest way to compile this package is: + + 1. ‘cd’ to the directory containing the package's source code and type + ‘./configure’ to configure the package for your system. + + Running ‘configure’ might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type ‘make’ to compile the package. + + 3. Optionally, type ‘make check’ to run any self-tests that come with + the package. + + 4. Type ‘make install’ to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing ‘make clean’. To also remove the + files that ‘configure’ created (so you can compile the package for + a different kind of computer), type ‘make distclean’. There is + also a ‘make maintainer-clean’ target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type ‘make uninstall’ to remove the installed + files again. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the ‘configure’ script does not know about. Run ‘./configure --help’ +for details on some of the pertinent environment variables. + + You can give ‘configure’ initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU ‘make’. ‘cd’ to the +directory where you want the object files and executables to go and run +the ‘configure’ script. ‘configure’ automatically checks for the +source code in the directory that ‘configure’ is in and in ‘..’. + + With a non-GNU ‘make’, it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use ‘make distclean’ before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple ‘-arch’ options to the +compiler but only a single ‘-arch’ option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" \ + --disable-dependency-tracking + + This is not guaranteed to produce working output in all cases. You +may have to build one architecture at a time and combine the results +using the ‘lipo’ tool if you have problems. + +Installation Names +================== + + By default, ‘make install’ installs the package's commands under +‘/usr/local/bin’, include files under ‘/usr/local/include’, etc. You +can specify an installation prefix other than ‘/usr/local’ by giving +‘configure’ the option ‘--prefix=PREFIX’. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option ‘--exec-prefix=PREFIX’ to ‘configure’, the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like ‘--bindir=DIR’ to specify different values for particular +kinds of files. Run ‘configure --help’ for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving ‘configure’ the +option ‘--program-prefix=PREFIX’ or ‘--program-suffix=SUFFIX’. + +Optional Features +================= + + Some packages pay attention to ‘--enable-FEATURE’ options to +‘configure’, where FEATURE indicates an optional part of the package. +They may also pay attention to ‘--with-PACKAGE’ options, where PACKAGE +is something like ‘gnu-as’ or ‘x’ (for the X Window System). The +‘README’ should mention any ‘--enable-’ and ‘--with-’ options that the +package recognizes. + + For packages that use the X Window System, ‘configure’ can usually +find the X include and library files automatically, but if it doesn't, +you can use the ‘configure’ options ‘--x-includes=DIR’ and +‘--x-libraries=DIR’ to specify their locations. + + For packages that use the GNU libiconv library, you can use the +‘configure’ option ‘--with-libiconv-prefix’ to specify the prefix you +used while installing GNU libiconv. This option is not necessary if +that other prefix is the same as the one now specified through --prefix. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its ‘<wchar.h>’ header file. The option ‘-nodtk’ can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put ‘/usr/ucb’ early in your ‘PATH’. This +directory contains several dysfunctional programs; working variants of +these programs are available in ‘/usr/bin’. So, if you need ‘/usr/ucb’ +in your ‘PATH’, put it _after_ ‘/usr/bin’. + + On Haiku, software installed for all users goes in ‘/boot/common’, +not ‘/usr/local’. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features ‘configure’ cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, ‘configure’ can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +‘--build=TYPE’ option. TYPE can either be a short name for the system +type, such as ‘sun4’, or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file ‘config.sub’ for the possible values of each field. If +‘config.sub’ isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option ‘--target=TYPE’ to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with ‘--host=TYPE’. + +Sharing Defaults +================ + + If you want to set default values for ‘configure’ scripts to share, +you can create a site shell script called ‘config.site’ that gives +default values for variables like ‘CC’, ‘cache_file’, and ‘prefix’. +‘configure’ looks for ‘PREFIX/share/config.site’ if it exists, then +‘PREFIX/etc/config.site’ if it exists. Or, you can set the +‘CONFIG_SITE’ environment variable to the location of the site script. +A warning: not all ‘configure’ scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to ‘configure’. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the ‘configure’ command line, using ‘VAR=value’. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified ‘gcc’ to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for ‘CONFIG_SHELL’ due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +‘configure’ Invocation +====================== + + ‘configure’ recognizes the following options to control how it +operates. + +‘--help’ +‘-h’ + Print a summary of all of the options to ‘configure’, and exit. + +‘--help=short’ +‘--help=recursive’ + Print a summary of the options unique to this package's + ‘configure’, and exit. The ‘short’ variant lists options used + only in the top level, while the ‘recursive’ variant lists options + also present in any nested packages. + +‘--version’ +‘-V’ + Print the version of Autoconf used to generate the ‘configure’ + script, and exit. + +‘--cache-file=FILE’ + Enable the cache: use and save the results of the tests in FILE, + traditionally ‘config.cache’. FILE defaults to ‘/dev/null’ to + disable caching. + +‘--config-cache’ +‘-C’ + Alias for ‘--cache-file=config.cache’. + +‘--quiet’ +‘--silent’ +‘-q’ + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to ‘/dev/null’ (any error + messages will still be shown). + +‘--srcdir=DIR’ + Look for the package's source code in directory DIR. Usually + ‘configure’ can determine that directory automatically. + +‘--prefix=DIR’ + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +‘--no-create’ +‘-n’ + Run the configure checks, but stop before creating any output + files. + +‘configure’ also accepts some other, not widely useful, options. Run +‘configure --help’ for more details. + |
