obstack: 64-bit obstack support, part 3
This finally enables full 64-bit obstack support. The glibc shared library
specific code is removed from obstack.c too, and the error handling code
conditionally compiled under control of another macro,
_OBSTACK_NO_ERROR_HANDLER.
* lib/obstack.h: Include string.h earlier.
(_OBSTACK_INTERFACE_VERSION): Define.
(_OBSTACK_SIZE_T, _CHUNK_SIZE_T): Define as size_t for version 2.
* lib/obstack.c: Don't include shlib-compat.h.
(OBSTACK_INTERFACE_VERSION): Delete.
(_OBSTACK_ELIDE_CODE): Rename from ELIDE_CODE. Define when version 1
glibc code is compatible with version 2. Don't include stdio.h for
__GNU_LIBRARY.
(obstack_exit_failure, print_and_abort, obstack_alloc_failed_handler):
Omit when _OBSTACK_NO_ERROR_HANDLER defined. Include stdio.h here.
(_obstack_compat, _obstack, _obstack_newchunk, obstack_free): Delete
glibc shared library specific source.

| 9 notice and this notice are preserved. This file is offered as-is, | |
| 10 without warranty of any kind. | |
| 3929 | 11 |
| 14135 | 12 Basic Installation |
| 13 ================== | |
| 3929 | 14 |
| 17467 | 15 Briefly, the shell command `./configure && make && make install' |
| 16 should configure, build, and install this package. The following | |
| 14135 | 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. | |
| 3929 | 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 | |
| 14135 | 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. | |
| 3929 | 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 | |
| 6817 | 47 `configure' by a program called `autoconf'. You need `configure.ac' if |
| 14135 | 48 you want to change it or regenerate `configure' using a newer version |
| 49 of `autoconf'. | |
| 3929 | 50 |
| 11740 | 51 The simplest way to compile this package is: |
| 3929 | 52 |
| 53 1. `cd' to the directory containing the package's source code and type | |
| 6817 | 54 `./configure' to configure the package for your system. |
| 3929 | 55 |
| 6817 | 56 Running `configure' might take a while. While running, it prints |
| 57 some messages telling which features it is checking for. | |
| 3929 | 58 |
| 59 2. Type `make' to compile the package. | |
| 60 | |
| 61 3. Optionally, type `make check' to run any self-tests that come with | |
| 11740 | 62 the package, generally using the just-built uninstalled binaries. |
| 3929 | 63 |
| 64 4. Type `make install' to install the programs and any data files and | |
| 11740 | 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. | |
| 3929 | 69 |
| 11740 | 70 5. Optionally, type `make installcheck' to repeat any self-tests, but |
| 71 this time using the binaries in their final installed location. | |
| 12192 | 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. | |
| 11740 | 76 |
| 77 6. You can remove the program binaries and object files from the | |
| 3929 | 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 | |
| 11740 | 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. | |

| 3929 | 102 |
| 3937 | 103 You can give `configure' initial values for configuration parameters |

| 14135 | 111 Compiling For Multiple Architectures |

114 You can compile the package for more than one kind of computer at the |
| 3929 | 115 same time, by placing the object files for each architecture in their |
| 6820 | 116 own directory. To do this, you can use GNU `make'. `cd' to the |
| 3929 | 117 directory where you want the object files and executables to go and run |
| 14135 | 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. | |
| 3929 | 121 |
| 6820 | 122 With a non-GNU `make', it is safer to compile the package for one |
| 6817 | 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. | |
| 3929 | 126 |
| 16957 | 127 On MacOS X 10.5 and later systems, you can create libraries and |
| 10352 | 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 | |

144 By default, `make install' installs the package's commands under |
| 5922 | 145 `/usr/local/bin', include files under `/usr/local/include', etc. You |
| 146 can specify an installation prefix other than `/usr/local' by giving | |
| 11740 | 147 `configure' the option `--prefix=PREFIX', where PREFIX must be an |
| 12192 | 148 absolute file name. |
| 3929 | 149 |
| 150 You can specify separate installation prefixes for | |
| 151 architecture-specific files and architecture-independent files. If you | |
| 5922 | 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. | |
| 3929 | 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 |
| 3929 | 158 kinds of files. Run `configure --help' for a list of the directories |
| 14135 | 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 `${prefix}', so that | |
| 11740 | 161 specifying just `--prefix' will affect all of the other directory |
| 12192 | 162 specifications that were not explicitly provided. |
| 11740 | 163 |
| 164 The most portable way to affect installation locations is to pass the | |
| 165 correct locations to `configure'; however, many packages provide one or | |
| 166 both of the following shortcuts of passing variable assignments to the | |
| 167 `make install' command line to change installation locations without | |
| 168 having to reconfigure or recompile. | |
| 169 | |
| 170 The first method involves providing an override variable for each | |
| 171 affected directory. For example, `make install | |
| 12192 | 172 prefix=/alternate/directory' will choose an alternate location for all |
| 173 directory configuration variables that were expressed in terms of | |
| 174 `${prefix}'. Any directories that were specified during `configure', | |
| 14135 | 175 but not in terms of `${prefix}', must each be overridden at install |
| 176 time for the entire installation to be relocated. The approach of | |
| 177 makefile variable overrides for each directory variable is required by | |
| 178 the GNU Coding Standards, and ideally causes no recompilation. | |
| 179 However, some platforms have known limitations with the semantics of | |
| 180 shared libraries that end up requiring recompilation when using this | |
| 181 method, particularly noticeable in packages that use GNU Libtool. | |
| 11740 | 182 |
| 183 The second method involves providing the `DESTDIR' variable. For | |
| 12192 | 184 example, `make install DESTDIR=/alternate/directory' will prepend |
| 185 `/alternate/directory' before all installation names. The approach of | |
| 11740 | 186 `DESTDIR' overrides is not required by the GNU Coding Standards, and |
| 187 does not work on platforms that have drive letters. On the other hand, | |
| 188 it does better at avoiding recompilation issues, and works well even | |
| 189 when some directory options were not specified in terms of `${prefix}' | |
| 12192 | 190 at `configure' time. |
| 11740 | 191 |
| 14135 | 192 Optional Features |
| 193 ================= | |
| 3929 | 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 |
| 3929 | 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 | |
| 11740 | 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 | |
| 14135 | 218 Particular systems |
| 219 ================== | |
| 10352 | 220 |
| 14135 | 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 | |
|
10365

|
223 order to use an ANSI C compiler: |
| 10352 | 224 |
| 10967 | 225 ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" |
| 10352 | 226 |
| 227 and if that doesn't work, install pre-built binaries of GCC for HP-UX. | |
| 228 | |
| 14233 | 229 HP-UX `make' updates targets which have the same time stamps as |
| 230 their prerequisites, which makes it generally unusable when shipped | |
| 231 generated files such as `configure' are involved. Use GNU `make' | |
| 232 instead. | |
| 233 | |
| 10352 | 234 On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot |
| 14135 | 235 parse its `<wchar.h>' header file. The option `-nodtk' can be used as |
| 236 a workaround. If GNU CC is not installed, it is therefore recommended | |
| 237 to try | |
| 10352 | 238 |
| 239 ./configure CC="cc" | |
| 240 | |
| 241 and if that doesn't work, try | |
| 242 | |
| 243 ./configure CC="cc -nodtk" | |
| 244 | |
| 10967 | 245 On Solaris, don't put `/usr/ucb' early in your `PATH'. This |
| 246 directory contains several dysfunctional programs; working variants of | |
| 247 these programs are available in `/usr/bin'. So, if you need `/usr/ucb' | |
| 248 in your `PATH', put it _after_ `/usr/bin'. | |
| 249 | |
| 250 On Haiku, software installed for all users goes in `/boot/common', | |
| 251 not `/usr/local'. It is recommended to use the following options: | |
| 252 | |
| 253 ./configure --prefix=/boot/common | |

300 Variables not defined in a site shell script can be set in the |
| 3929 | 301 environment passed to `configure'. However, some packages may run |
| 302 configure again during the build, and the customized values of these | |
| 303 variables may be lost. In order to avoid this problem, you should set | |
| 304 them in the `configure' command line, using `VAR=value'. For example: | |
| 305 | |
| 306 ./configure CC=/usr/local2/bin/gcc | |
| 307 | |
| 5633 | 308 causes the specified `gcc' to be used as the C compiler (unless it is |
| 6640 | 309 overridden in the site shell script). |
| 5633 | 310 |
| 14135 | 311 Unfortunately, this technique does not work for `CONFIG_SHELL' due to |
| 16192 | 312 an Autoconf limitation. Until the limitation is lifted, you can use |
| 313 this workaround: | |

329 Print a summary of the options unique to this package's |
| 14135 | 330 `configure', and exit. The `short' variant lists options used |
| 331 only in the top level, while the `recursive' variant lists options | |
| 332 also present in any nested packages. | |
| 3929 | 333 |
| 334 `--version' | |
| 335 `-V' | |
| 336 Print the version of Autoconf used to generate the `configure' | |
| 337 script, and exit. | |
| 338 | |
| 339 `--cache-file=FILE' | |
| 340 Enable the cache: use and save the results of the tests in FILE, | |
| 341 traditionally `config.cache'. FILE defaults to `/dev/null' to | |
| 342 disable caching. | |
| 343 | |
| 344 `--config-cache' | |
| 345 `-C' | |
| 346 Alias for `--cache-file=config.cache'. | |
| 347 | |
| 348 `--quiet' | |
| 349 `--silent' | |
| 350 `-q' | |
| 351 Do not print messages saying which checks are being made. To | |
| 352 suppress all normal output, redirect it to `/dev/null' (any error | |
| 353 messages will still be shown). | |
| 354 | |
| 355 `--srcdir=DIR' | |
| 356 Look for the package's source code in directory DIR. Usually | |
| 357 `configure' can determine that directory automatically. | |
