This file is offered as-is, 10 without warranty of any kind. 11 12 Basic Installation 13 ================== 14 15 Briefly, the shell commands `./configure; make; make install' should 16 configure, build, and install this package. The following 17 more-detailed instructions are generic; see the `README' file for 18 instructions specific to this package. Some packages provide this 19 `INSTALL' file but do not implement all of the features documented 20 below. The lack of an optional feature in a given package is not 21 necessarily a bug. More recommendations for GNU packages can be found 22 in *note Makefile Conventions: (standards)Makefile Conventions. 23 24 The `configure' shell script attempts to guess correct values for 25 various system-dependent variables used during compilation. It uses 26 those values to create a `Makefile' in each directory of the package. 27 It may also create one or more `.h' files containing system-dependent 28 definitions. Finally, it creates a shell script `config.status' that 29 you can run in the future to recreate the current configuration, and a 30 file `config.log' containing compiler output (useful mainly for 31 debugging `configure'). 32 33 It can also use an optional file (typically called `config.cache' 34 and enabled with `--cache-file=config.cache' or simply `-C') that saves 35 the results of its tests to speed up reconfiguring. Caching is 36 disabled by default to prevent problems with accidental use of stale 37 cache files. 38 39 If you need to do unusual things to compile the package, please try 40 to figure out how `configure' could check whether to do them, and mail 41 diffs or instructions to the address given in the `README' so they can 42 be considered for the next release. If you are using the cache, and at 43 some point `config.cache' contains results you don't want to keep, you 44 may remove or edit it. 45 46 The file `configure.ac' (or `configure.in') is used to create 47 `configure' by a program called `autoconf'. You need `configure.ac' if 48 you want to change it or regenerate `configure' using a newer version 49 of `autoconf'. 50 51 The simplest way to compile this package is: 52 53 1. `cd' to the directory containing the package's source code and type 54 `./configure' to configure the package for your system. 55 56 Running `configure' might take a while. While running, it prints 57 some messages telling which features it is checking for. 58 59 2. Type `make' to compile the package. 60 61 3. Optionally, type `make check' to run any self-tests that come with 62 the package, generally using the just-built uninstalled binaries. 63 64 4. Type `make install' to install the programs and any data files and 65 documentation. When installing into a prefix owned by root, it is 66 recommended that the package be configured and built as a regular 67 user, and only the `make install' phase executed with root 68 privileges. 69 70 5. Optionally, type `make installcheck' to repeat any self-tests, but 71 this time using the binaries in their final installed location. 72 This target does not install anything. Running this target as a 73 regular user, particularly if the prior `make install' required 74 root privileges, verifies that the installation completed 75 correctly. 76 77 6. You can remove the program binaries and object files from the 78 source code directory by typing `make clean'. To also remove the 79 files that `configure' created (so you can compile the package for 80 a different kind of computer), type `make distclean'. There is 81 also a `make maintainer-clean' target, but that is intended mainly 82 for the package's developers. If you use it, you may have to get 83 all sorts of other programs in order to regenerate files that came 84 with the distribution. 85 86 7. Often, you can also type `make uninstall' to remove the installed 87 files again. In practice, not all packages have tested that 88 uninstallation works correctly, even though it is required by the 89 GNU Coding Standards. 90 91 8. Some packages, particularly those that use Automake, provide `make 92 distcheck', which can by used by developers to test that all other 93 targets like `make install' and `make uninstall' work correctly. 94 This target is generally not run by end users. 95 96 Compilers and Options 97 ===================== 98 99 Some systems require unusual options for compilation or linking that 100 the `configure' script does not know about. Run `./configure --help' 101 for details on some of the pertinent environment variables. 102 103 You can give `configure' initial values for configuration parameters 104 by setting variables in the command line or in the environment. Here 105 is an example: 106 107 ./configure CC=c99 CFLAGS=-g LIBS=-lposix 108 109 *Note Defining Variables::, for more details. 110 111 Compiling For Multiple Architectures 112 ==================================== 113 114 You can compile the package for more than one kind of computer at the 115 same time, by placing the object files for each architecture in their 116 own directory. To do this, you can use GNU `make'. `cd' to the 117 directory where you want the object files and executables to go and run 118 the `configure' script. `configure' automatically checks for the 119 source code in the directory that `configure' is in and in `..'. This 120 is known as a "VPATH" build. 121 122 With a non-GNU `make', it is safer to compile the package for one 123 architecture at a time in the source code directory. After you have 124 installed the package for one architecture, use `make distclean' before 125 reconfiguring for another architecture. 126 127 On MacOS X 10.5 and later systems, you can create libraries and 128 executables that work on multiple system types--known as "fat" or 129 "universal" binaries--by specifying multiple `-arch' options to the 130 compiler but only a single `-arch' option to the preprocessor. Like 131 this: 132 133 ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 134 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ 135 CPP="gcc -E" CXXCPP="g++ -E" 136 137 This is not guaranteed to produce working output in all cases, you 138 may have to build one architecture at a time and combine the results 139 using the `lipo' tool if you have problems. 140 141 Installation Names 142 ================== 143 144 By default, `make install' installs the package's commands under 145 `/usr/local/bin', include files under `/usr/local/include', etc. You 146 can specify an installation prefix other than `/usr/local' by giving 147 `configure' the option `--prefix=PREFIX', where PREFIX must be an 148 absolute file name. 149 150 You can specify separate installation prefixes for 151 architecture-specific files and architecture-independent files. If you 152 pass the option `--exec-prefix=PREFIX' to `configure', the package uses 153 PREFIX as the prefix for installing programs and libraries. 154 Documentation and other data files still use the regular prefix. 155 156 In addition, if you use an unusual directory layout you can give 157 options like `--bindir=DIR' to specify different values for particular 158 kinds of files. Run `configure --help' for a list of the directories 159 you can set and what kinds of files go in them. In general, the 160 default for these options is expressed in terms of `${prefix}', so that 161 specifying just `--prefix' will affect all of the other directory 162 specifications that were not explicitly provided. 163 164 The most portable way to affect installation locations is to pass the 165 correct locations to `configure'; however, many packages provide one or 166 both of the following shortcuts of passing variable assignments to the 167 `make install' command line to change installation locations without 168 having to reconfigure or recompile. 169 170 The first method involves providing an override variable for each 171 affected directory. For example, `make install 172 prefix=/alternate/directory' will choose an alternate location for all 173 directory configuration variables that were expressed in terms of 174 `${prefix}'. Any directories that were specified during `configure', 175 but not in terms of `${prefix}', must each be overridden at install 176 time for the entire installation to be relocated. The approach of 177 makefile variable overrides for each directory variable is required by 178 the GNU Coding Standards, and ideally causes no recompilation. 179 However, some platforms have known limitations with the semantics of 180 shared libraries that end up requiring recompilation when using this 181 method, particularly noticeable in packages that use GNU Libtool. 182 183 The second method involves providing the `DESTDIR' variable. For 184 example, `make install DESTDIR=/alternate/directory' will prepend 185 `/alternate/directory' before all installation names. The approach of 186 `DESTDIR' overrides is not required by the GNU Coding Standards, and 187 does not work on platforms that have drive letters. On the other hand, 188 it does better at avoiding recompilation issues, and works well even 189 when some directory options were not specified in terms of `${prefix}' 190 at `configure' time. 191 192 Optional Features 193 ================= 194 195 If the package supports it, you can cause programs to be installed 196 with an extra prefix or suffix on their names by giving `configure' the 197 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. 198 199 Some packages pay attention to `--enable-FEATURE' options to 200 `configure', where FEATURE indicates an optional part of the package. 201 They may also pay attention to `--with-PACKAGE' options, where PACKAGE 202 is something like `gnu-as' or `x' (for the X Window System). The 203 `README' should mention any `--enable-' and `--with-' options that the 204 package recognizes. 205 206 For packages that use the X Window System, `configure' can usually 207 find the X include and library files automatically, but if it doesn't, 208 you can use the `configure' options `--x-includes=DIR' and 209 `--x-libraries=DIR' to specify their locations. 210 211 Some packages offer the ability to configure how verbose the 212 execution of `make' will be. For these packages, running `./configure 213 --enable-silent-rules' sets the default to minimal output, which can be 214 overridden with `make V=1'; while running `./configure 215 --disable-silent-rules' sets the default to verbose, which can be 216 overridden with `make V=0'. 217 218 Particular systems 219 ================== 220 221 On HP-UX, the default C compiler is not ANSI C compatible. If GNU 222 CC is not installed, it is recommended to use the following options in 223 order to use an ANSI C compiler: 224 225 ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" 226 227 and if that doesn't work, install pre-built binaries of GCC for HP-UX. 228 229 On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot 230 parse its `<wchar.h>' header file. The option `-nodtk' can be used as 231 a workaround. If GNU CC is not installed, it is therefore recommended 232 to try 233 234 ./configure CC="cc" 235 236 and if that doesn't work, try 237 238 ./configure CC="cc -nodtk" 239 240 On Solaris, don't put `/usr/ucb' early in your `PATH'. This 241 directory contains several dysfunctional programs; working variants of 242 these programs are available in `/usr/bin'. So, if you need `/usr/ucb' 243 in your `PATH', put it _after_ `/usr/bin'. 244 245 On Haiku, software installed for all users goes in `/boot/common', 246 not `/usr/local'. It is recommended to use the following options: 247 248 ./configure --prefix=/boot/common 249 250 Specifying the System Type 251 ========================== 252 253 There may be some features `configure' cannot figure out 254 automatically, but needs to determine by the type of machine the package 255 will run on. Usually, assuming the package is built to be run on the 256 _same_ architectures, `configure' can figure that out, but if it prints 257 a message saying it cannot guess the machine type, give it the 258 `--build=TYPE' option. TYPE can either be a short name for the system 259 type, such as `sun4', or a canonical name which has the form: 260 261 CPU-COMPANY-SYSTEM 262 263 where SYSTEM can have one of these forms: 264 265 OS 266 KERNEL-OS 267 268 See the file `config.sub' for the possible values of each field. If 269 `config.sub' isn't included in this package, then this package doesn't 270 need to know the machine type. 271 272 If you are _building_ compiler tools for cross-compiling, you should 273 use the option `--target=TYPE' to select the type of system they will 274 produce code for. 275 276 If you want to _use_ a cross compiler, that generates code for a 277 platform different from the build platform, you should specify the 278 "host" platform (i.e., that on which the generated programs will 279 eventually be run) with `--host=TYPE'. 280 281 Sharing Defaults 282 ================ 283 284 If you want to set default values for `configure' scripts to share, 285 you can create a site shell script called `config.site' that gives 286 default values for variables like `CC', `cache_file', and `prefix'. 287 `configure' looks for `PREFIX/share/config.site' if it exists, then 288 `PREFIX/etc/config.site' if it exists. Or, you can set the 289 `CONFIG_SITE' environment variable to the location of the site script. 290 A warning: not all `configure' scripts look for a site script. 291 292 Defining Variables 293 ================== 294 295 Variables not defined in a site shell script can be set in the 296 environment passed to `configure'. However, some packages may run 297 configure again during the build, and the customized values of these 298 variables may be lost. In order to avoid this problem, you should set 299 them in the `configure' command line, using `VAR=value'. For example: 300 301 ./configure CC=/usr/local2/bin/gcc 302 303 causes the specified `gcc' to be used as the C compiler (unless it is 304 overridden in the site shell script). 305 306 Unfortunately, this technique does not work for `CONFIG_SHELL' due to 307 an Autoconf bug. Until the bug is fixed you can use this workaround: 308 309 CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash 310 311 `configure' Invocation 312 ====================== 313 314 `configure' recognizes the following options to control how it 315 operates. 316 317 `--help' 318 `-h' 319 Print a summary of all of the options to `configure', and exit. 320 321 `--help=short' 322 `--help=recursive' 323 Print a summary of the options unique to this package's 324 `configure', and exit. The `short' variant lists options used 325 only in the top level, while the `recursive' variant lists options 326 also present in any nested packages. 327 328 `--version' 329 `-V' 330 Print the version of Autoconf used to generate the `configure' 331 script, and exit. 332 333 `--cache-file=FILE' 334 Enable the cache: use and save the results of the tests in FILE, 335 traditionally `config.cache'. FILE defaults to `/dev/null' to 336 disable caching. 337 338 `--config-cache' 339 `-C' 340 Alias for `--cache-file=config.cache'. 341 342 `--quiet' 343 `--silent' 344 `-q' 345 Do not print messages saying which checks are being made. To 346 suppress all normal output, redirect it to `/dev/null' (any error 347 messages will still be shown). 348 349 `--srcdir=DIR' 350 Look for the package's source code in directory DIR. Usually 351 `configure' can determine that directory automatically. 352 353 `--prefix=DIR' 354 Use DIR as the installation prefix. *note Installation Names:: 355 for more details, including other options available for fine-tuning 356 the installation locations. 357 358 `--no-create' 359 `-n' 360 Run the configure checks, but stop before creating any output 361 files. 362 363 `configure' also accepts some other, not widely useful, options. Run 364 `configure --help' for more details. 365 1 Please follow the instructions at 2 https://trac.fact-project.org/wiki/InstallingFACT++
