 192 This chapter explains how to write modules of your own, either to
 193 extend Gnulib for your own package (@pxref{Extending Gnulib}), or for
 194 inclusion in gnulib proper.

 196 The guidelines in this chapter do not necessarily need to be followed for
 197 using @code{gnulib-tool}.  They merely represent a set of good practices.
 198 Following them will result in a good structure of your modules and in

 216
 217 Every API (C functions or variables) provided should be declared in a header
 218 file (.h file) and implemented in one or more implementation files (.c files).
 219 The separation has the effect that users of your module need to read only
 220 the contents of the .h file and the module description in order to understand
 221 what the module is about and how to use it---not the entire implementation.
 222 Furthermore, users of your module don't need to repeat the declarations of
 223 the functions in their code, and are likely to receive notification through
 224 compiler errors if you make incompatible changes to the API (like, adding a
 225 parameter or changing the return type of a function).
 226
 227
 228 @node Header files
 229 @section Header files
 230
 231 The .h file should declare the C functions and variables that the module
 232 provides.
 233
 234 The .h file should be stand-alone.  That is, it does not require other .h files
 235 to be included before.  Rather, it includes all necessary .h files by itself.
 236
 237 @cindex double inclusion of header files
 238 @cindex header file include protection
 239 It is a tradition to use CPP tricks to avoid parsing the same header
 240 file more than once, which might cause warnings.  The trick is to wrap
 241 the content of the header file (say, @file{foo.h}) in a block, as in:
 242
 243 @example
 244 #ifndef FOO_H
 245 # define FOO_H
 246 ...
 247 body of header file goes here
 248 ...
 249 #endif /* FOO_H */
 250 @end example
 251
 252 Whether to use @code{FOO_H} or @code{_FOO_H} is a matter of taste and
 253 style.  The C99 and C11 standards reserve all identifiers that begin with an
 254 underscore and either an uppercase letter or another underscore, for
 255 any use.  Thus, in theory, an application might not safely assume that
 256 @code{_FOO_H} has not already been defined by a library.  On the other
 257 hand, using @code{FOO_H} will likely lead the higher risk of
 258 collisions with other symbols (e.g., @code{KEY_H}, @code{XK_H}, @code{BPF_H},
 259 which are CPP macro constants, or @code{COFF_LONG_H}, which is a CPP
 260 macro function).  Your preference may depend on whether you consider
 261 the header file under discussion as part of the application (which has
 262 its own namespace for CPP symbols) or a supporting library (that
 263 shouldn't interfere with the application's CPP symbol namespace).
 264
 265 @cindex C++ header files
 266 @cindex Header files and C++
 267 Adapting C header files for use in C++ applications can use another
 268 CPP trick, as in:
 269
 270 @example
 271 # ifdef __cplusplus
 272 extern "C"
 273 @{
 274 # endif
 275 ...
 276 body of header file goes here
 277 ...
 278 # ifdef __cplusplus
 279 @}
 280 # endif
 281 @end example
 282
 283 The idea here is that @code{__cplusplus} is defined only by C++
 284 implementations, which will wrap the header file in an @samp{extern "C"}
 285 block.  Again, whether to use this trick is a matter of taste and
 286 style.  While the above can be seen as harmless, it could be argued
 287 that the header file is written in C, and any C++ application using it
 288 should explicitly use the @samp{extern "C"} block itself.  Your
 289 preference might depend on whether you consider the API exported by
 290 your header file as something available for C programs only, or for C
 291 and C++ programs alike.
 292
 293 Note that putting a @code{#include} in an @code{extern "C" @{ ... @}}
 294 block yields a syntax error in C++ mode on some platforms (e.g., glibc
 295 systems with g++ v3.3 to v4.2, AIX, IRIX).  For this reason, it
 296 is recommended to place the @code{#include} before the @code{extern
 297 "C"} block.
 298
 299 @node Implementation files
 300 @section Implementation files
 301
 302 The .c file or files implement the functions and variables declared in the
 303 .h file.
 304
 305 @subheading Include ordering
 306
 307 Every implementation file must start with @samp{#include <config.h>}.
 308 This is necessary for activating the preprocessor macros that are defined
 309 on behalf of the Autoconf macros.  Some of these preprocessor macros,
 310 such as @code{_GNU_SOURCE}, would have no effect if defined after a system
 311 header file has already been included.
 312
 313 Then comes the @samp{#include "..."} specifying the header file that is
 314 being implemented.  Putting this right after @samp{#include <config.h>}
 315 has the effect that it verifies that the header file is self-contained.
 316
 317 Then come the system and application headers. It is customary to put all the
 318 system headers before all application headers, so as to minimize the risk
 319 that a preprocessor macro defined in an application header confuses the system
 320 headers on some platforms.
 321
 322 In summary:
 323
 324 @itemize
 325 @item
 326 First comes #include <config.h>.
 327 @item
 328 Second comes the #include "..." specifying the module being implemented.
 329 @item
 330 Then come all the #include <...> of system or system-replacement headers,
 331 in arbitrary order.
 332 @item
 333 Then come all the #include "..." of gnulib and application headers, in

 338 @node Specification
 339 @section Specification
 340
 341 The specification of a function should answer at least the following
 342 questions:
 343 @itemize
 344 @item
 345 What is the purpose of the function?
 346 @item
 347 What are the arguments?
 348 @item
 349 What is the return value?
 350 @item
 351 What happens in case of failure? (Exit? A specific return value? Errno set?)
 352 @item
 353 Memory allocation policy: If pointers to memory are returned, are they freshly
 354 allocated and supposed to be freed by the caller?
 355 @end itemize
 356
 357 @cindex specification
 358 @cindex comments describing functions
 359 @cindex describing functions, locating
 360 Where to put the specification describing exported functions? Three practices
 361 are used in gnulib:
 362
 363 @itemize
 364 @item
 365 The specification can be as comments in the header file, just above the
 366 function declaration.
 367 @item
 368 The specification can be as comments in the implementation file, just above
 369 the function definition.
 370 @item
 371 The specification can be in texinfo format, so that it gets included in the
 372 gnulib manual.
 373 @end itemize
 374
 375 In any case, the specification should appear in just one place, unless you can
 376 ensure that the multiple copies will always remain identical.
 377
 378 The advantage of putting it in the header file is that the user only has to
 379 read the include file normally never needs to peek into the implementation
 380 file(s).
 381
 382 The advantage of putting it in the implementation file is that when reviewing
 383 or changing the implementation, you have both elements side by side.
 384
 385 The advantage of texinfo formatted documentation is that it is easily
 386 published in HTML or Info format.
 387
 388 Currently (as of 2020), 70% of gnulib uses the first practice, 25% of
 389 gnulib uses the second practice, and a small minority uses the texinfo
 390 practice.
 391
 392
 393 @node Module description
 394 @section Module description
 395
 396 For the module description, you can start from an existing module's
 397 description, or from a blank one: @file{module/TEMPLATE} for a normal module,
 398 or @file{module/TEMPLATE-TESTS} for a unit test module.  Some more fields
 399 are possible but rarely used.  Use @file{module/TEMPLATE-EXTENDED} if you
 400 want to use one of them.
 401
 402 Module descriptions have the following fields.  Absent fields are equivalent
 403 to fields with empty contents.
 404
 405 @table @asis
 406 @item Description
 407 This field should contain a concise description of the module's functionality.
 408 One sentence is enough.  For example, if it defines a single function
 409 @samp{frob}, the description can be @samp{frob() function: frobnication.}
 410 Gnulib's documentation generator will automatically convert the first part
 411 to a hyperlink when it has this form.
 412
 413 @item Status
 414 This field is either empty/absent, or contains the word @samp{obsolete}.  In
 415 the latter case, @command{gnulib-tool} will, unless the option
 416 @code{--with-obsolete} is given, omit it when it used as a dependency.  It is
 417 good practice to also notify the user about an obsolete module.  This is done
 418 by putting into the @samp{Notice} section (see below) text like
 419 @samp{This module is obsolete.}
 420
 421 @item Notice
 422 This field contains text that @command{gnulib-tool} will show to the user
 423 when the module is used.  This can be a status indicator like
 424 @samp{This module is obsolete.} or additional advice.  Do not abuse this
 425 field.
 426
 427 @item Applicability
 428 This field is either empty/absent, or contains the word @samp{all}.  It
 429 describes to which @code{Makefile.am} the module is applied.  By default,
 430 a normal module is applied to @code{@var{source_base}/Makefile.am}
 431 (normally @code{lib/Makefile.am}), whereas a module ending in @code{-tests}
 432 is applied to @code{@var{tests_base}/Makefile.am} (normally
 433 @code{tests/Makefile.am}).  If this field is @samp{all}, it is applied to
 434 both @code{Makefile.am}s.  This is useful for modules which provide
 435 Makefile.am macros rather than compiled source code.
 436
 437 @item Files
 438 This field contains a newline separated list of the files that are part of
 439 the module.  @code{gnulib-tool} copies these files into the package that
 440 uses the module.
 441
 442 This list is typically ordered by importance: First comes the header file,
 443 then the implementation files, then other files.
 444
 445 It is possible to have the same file mentioned in multiple modules.  That is,
 446 if the maintainers of that module agree on the purpose and future of said
 447 file.
 448
 449 @item Depends-on
 450 This field contains a newline separated list of the modules that are required
 451 for the proper working of this module.  @code{gnulib-tool} includes each
 452 required module automatically, unless it is specified with option
 453 @code{--avoid} or it is marked as obsolete and the option
 454 @code{--with-obsolete} is not given.
 455
 456 A test modules @code{foo-tests} implicitly depends on the corresponding non-test
 457 module @code{foo}.  @code{foo} implicitly depends on @code{foo-tests} if the
 458 latter exists and if the option @code{--with-tests} has been given.
 459
 460 Tests modules can depend on non-tests modules.  Non-tests modules should not
 461 depend on tests modules. (Recall that tests modules are built in a separate
 462 directory.)
 463
 464 Each listed required module may be declared a conditional dependency.  This
 465 is indicated by placing the condition for the dependency on the same line,
 466 enclosed in brackets, after the name of the required module.  The condition
 467 is a shell expression that is run after the module's @code{configure.ac}
 468 statements.  For example:
 469 @smallexample
 470 strtoull   [test $ac_cv_func_strtoumax = no]
 471 @end smallexample
 472
 473 Lines starting with @code{#} are recognized as comments and are ignored.
 474
 475 @item configure.ac-early
 476 This field contains @file{configure.ac} stuff (Autoconf macro invocations and
 477 shell statements) that are logically placed early in the @file{configure.ac}
 478 file: right after the @code{AC_PROG_CC} invocation.  This section is adequate
 479 for statements that modify @code{CPPFLAGS}, as these can affect the results of
 480 other Autoconf macros.
 481
 482 @item configure.ac
 483 This field contains @file{configure.ac} stuff (Autoconf macro invocations and
 484 shell statements).
 485
 486 It is forbidden to add items to the @code{CPPFLAGS} variable here, other than
 487 temporarily, as these could affect the results of other Autoconf macros.
 488
 489 We avoid adding items to the @code{LIBS} variable, other than temporarily.
 490 Instead, the module can export an Autoconf-substituted variable that contains
 491 link options.  The user of the module can then decide to which executables
 492 to apply which link options.  Recall that a package can build executables of
 493 different kinds and purposes; having all executables link against all
 494 libraries is inappropriate.
 495
 496 If the statements in this section grow larger than a couple of lines, we
 497 recommend moving them to a @code{.m4} file of their own.
 498
 499 @item Makefile.am
 500 This field contains @code{Makefile.am} statements.  Variables like
 501 @code{lib_SOURCES} are transformed to match the name of the library
 502 being built in that directory.  For example, @code{lib_SOURCES} may become
 503 @code{libgnu_a_SOURCES} (for a plain library) or @code{libgnu_la_SOURCES}
 504 (for a libtool library).  Therefore, the normal way of having an
 505 implementation file @code{lib/foo.c} compiled unconditionally is to write
 506 @smallexample
 507 lib_SOURCES += foo.c
 508 @end smallexample
 509
 510 @item Include
 511 This field contains the preprocessor statements that users of the module
 512 need to add to their source code files.  Typically it's a single include
 513 statement.  A shorthand is allowed: You don't need to write the word
 514 ``#include'', just the name of the include file in the way it will appear
 515 in an include statement.  Example:
 516 @smallexample
 517 "foo.h"
 518 @end smallexample
 519
 520 @item Link
 521 This field contains the set of libraries that are needed when linking
 522 libraries or executables that use this module.  Often this will be
 523 written as a reference to a Makefile variable.  Please write them
 524 one per line, so that @command{gnulib-tool} can remove duplicates
 525 when presenting a summary to the user.
 526 Example:
 527 @smallexample
 528 $(POW_LIBM)
 529 $(LTLIBICONV) when linking with libtool, $(LIBICONV) otherwise
 530 @end smallexample

 537 source code file, a copyright notice and the appropriate license notice,
 538 taken from the @file{etc/license-notices/} directory.

 540 @item Maintainer
 541 This field specifies the persons who have a definitive say about proposed

 550 @section Autoconf macros
 551
 552 For a module @code{foo}, an Autoconf macro file @file{m4/foo.m4} is typically
 553 created when the Autoconf macro invocations for the module are longer than
 554 one or two lines.
 555
 556 The name of the main entry point into this Autoconf macro file is typically
 557 @code{gl_FOO}.  For modules outside Gnulib that are not likely to be moved
 558 into Gnulib, please use a prefix specific to your package: @code{gt_} for
 559 GNU gettext, @code{cu_} for GNU coreutils, etc.
 560
 561 For modules that define a function @code{foo}, the entry point is called
 562 @code{gl_FUNC_FOO} instead of @code{gl_FOO}.  For modules that provide a
 563 header file with multiple functions, say @code{foo.h}, the entry point is
 564 called @code{gl_FOO_H} or @code{gl_HEADER_FOO_H}.  This convention is useful
 565 because sometimes a header and a function name coincide (for example,
 566 @code{fcntl} and @code{fcntl.h}).
 567
 568 For modules that provide a replacement, it is useful to split the Autoconf
 569 macro into two macro definitions: one that detects whether the replacement
 570 is needed and requests the replacement by setting a @code{HAVE_FOO}
 571 variable to 0 or a @code{REPLACE_FOO} variable to 1 (this is the
 572 entry point, say @code{gl_FUNC_FOO}), and one that arranges for the macros
 573 needed by the replacement code @code{lib/foo.c} (typically called
 574 @code{gl_PREREQ_FOO}).  The reason of this separation is
 575 @enumerate
 576 @item
 577 to make it easy to update the Autoconf macros when you have modified the
 578 source code file: after changing @code{lib/foo.c}, all you have to review
 579 is the @code{Depends-on} section of the module description and the
 580 @code{gl_PREREQ_FOO} macro in the Autoconf macro file.
 581 @item
 582 The Autoconf macros are often large enough that splitting them eases
 583 maintenance.

 587 @node Using @code{AC_LIBOBJ}
 588 @section Making proper use of @code{AC_LIBOBJ}
 589
 590 Source files that provide a replacement should be only compiled on the
 591 platforms that need this replacement.  While it is actually possible
 592 to compile a @code{.c} file whose contents is entirely @code{#ifdef}'ed
 593 out on the platforms that don't need the replacement, this practice is
 594 discouraged because
 595 @itemize @bullet
 596 @item
 597 It makes the build time longer than needed, by invoking the compiler for
 598 nothing.
 599 @item
 600 It produces a @code{.o} file that suggests that a replacement was needed.
 601 @item
 602 Empty object files produce a linker warning on some platforms: MSVC.
 603 @end itemize
 604
 605 The typical idiom for invoking @code{AC_LIBOBJ} is thus the following,
 606 in the module description:
 607
 608 @smallexample
 609 if test $HAVE_FOO = 0 || test $REPLACE_FOO = 1; then
 610   AC_LIBOBJ([foo])
 611   gl_PREREQ_FOO
 612 fi
 613 @end smallexample
 614
 615 Important: Do not place @code{AC_LIBOBJ} invocations in the Autoconf
 616 macros in the @code{m4/} directory.  The purpose of the Autoconf macros
 617 is to determine what features or bugs the platform has, and to make
 618 decisions about which replacements are needed.  The purpose of the
 619 @code{configure.ac} and @code{Makefile.am} sections of the module
 620 descriptions is to arrange for the replacements to be compiled.
 621 @strong{Source file names do not belong in the @code{m4/} directory.}
 622
 623 When an @code{AC_LIBOBJ} invocation is unconditional, it is simpler
 624 to just have the source file compiled through an Automake variable
 625 augmentation: In the @code{Makefile.am} section write
 626
 627 @smallexample
 628 lib_SOURCES += foo.c
 629 @end smallexample
 630
 631 When a module description contains an @code{AC_LIBOBJ([foo])}
 632 invocation, you @strong{must} list the source file @code{lib/foo.c}
 633 in the @code{Files} section.  This is needed even if the module
 634 depends on another module that already lists @code{lib/foo.c} in its
 635 @code{Files} section -- because your module might be used among
 636 the test modules (in the directory specified through @samp{--tests-base})
 637 and the other module among the main modules (in the directory specified
 638 through @samp{--source-base}), and in this situation, the
 639 @code{AC_LIBOBJ([foo])} of your module can only be satisfied by having
 640 @code{foo.c} be present in the tests source directory as well.
 641
 642 @node Unit test modules
 643 @section Unit test modules
 644
 645 A unit test that is a simple C program usually has a module description as
 646 simple as this:
 647
 648 @smallexample
 649 Files:
 650 tests/test-foo.c
 651 tests/macros.h
 652
 653 Depends-on:
 654
 655 configure.ac:
 656
 657 Makefile.am:
 658 TESTS += test-foo
 659 check_PROGRAMS += test-foo
 660 @end smallexample
 661
 662 The test program @file{tests/test-foo.c} often has the following structure:
 663
 664 @itemize
 665 @item
 666 First comes the obligatory @samp{#include <config.h>}.
 667
 668 @item
 669 Second comes the include of the header file that declares the API being tested.
 670 Including it here verifies that said header file is self-contained.
 671
 672 @item
 673 Then come other includes.  In particular, the file @file{macros.h} is often
 674 used here.  It contains a convenient @code{ASSERT} macro.
 675 @end itemize
 676
 677 The body of the test, then, contains many @code{ASSERT} invocations.  When
 678 a test fails, the @code{ASSERT} macro prints the line number of the failing
 679 statement, thus giving you, the developer, an idea of which part of the test
 680 failed, even when you don't have access to the machine where the test failed
 681 and the reporting user cannot run a debugger.
 682
 683 Sometimes it is convenient to write part of the test as a shell script.
 684 (For example, in areas related to process control or interprocess
 685 communication, or when different locales should be tried.) In these cases,
 686 the typical module description is like this:
 687
 688 @smallexample
 689 Files:
 690 tests/test-foo.sh
 691 tests/test-foo.c
 692 tests/macros.h
 693
 694 Depends-on:
 695
 696 configure.ac:
 697
 698 Makefile.am:
 699 TESTS += test-foo.sh
 700 TESTS_ENVIRONMENT += FOO_BAR='@@FOO_BAR@@'
 701 check_PROGRAMS += test-foo
 702 @end smallexample
 703
 704 Here, the @code{TESTS_ENVIRONMENT} variable can be used to pass values
 705 determined by @code{configure} or by the @code{Makefile} to the shell
 706 script, as environment variables.  The Autoconf values @code{EXEEXT}
 707 and @code{srcdir} are already provided as environment variables,
 708 through an initial value of @code{TESTS_ENVIRONMENT} that
 709 @code{gnulib-tool} puts in place.
 710
 711 Regardless of the specific form of the unit test, the following guidelines
 712 should be respected:
 713
 714 @itemize
 715 @item
 716 A test indicates success by exiting with exit code 0.  It should normally
 717 not produce output in this case.  (Output to temporary files that are
 718 cleaned up at the end of the test are possible, of course.)
 719 @item
 720 A test indicates failure by exiting with an exit code different from 0 and 77,
 721 typically 1.  It is useful to print a message about the failure in this case.
 722 The @code{ASSERT} macro already does so.
 723 @item
 724 A test indicates "skip", that is, that most of its interesting functionality
 725 could not be performed, through a return code of 77.  A test should also
 726 print a message to stdout or stderr about the reason for skipping.
 727 For example:
 728 @smallexample
 729   fputs ("Skipping test: multithreading not enabled\n", stderr);
 730   return 77;
 731 @end smallexample
 732 Such a message helps detecting bugs in the autoconf macros: A simple message
 733 @samp{SKIP: test-foo} does not sufficiently catch the attention of the user.

 756 @chapter Extending Gnulib
 757
 758 Gnulib modules are intended to be suitable for widespread use.  Most
 759 problems with Gnulib can and should be fixed in a generic way, so that
 760 all of Gnulib's users can benefit from the change.  But occasionally a
 761 problem arises that is difficult or undesirable to fix generically, or
 762 a project that uses Gnulib may need to work around an issue before the
 763 Gnulib maintainers commit a final fix.  Maintainers may also want to
 764 add their own pools of modules to projects as Gnulib ``staging
 765 areas.''
 766
 767 The obvious way to make local changes to Gnulib modules is to use
 768 @command{gnulib-tool} to check out pristine modules, then to modify
 769 the results in-place.  This works well enough for short-lived
 770 experiments.  It is harder to keep modified versions of Gnulib modules
 771 for a long time, even though Git (or another distributed version
 772 control systems) can help out a lot with this during the development
 773 process.
 774
 775 Git, however, doesn't address the distribution issue.  When a package
 776 ``foobar'' needs a modified version of, say, @file{stdint.in.h}, it
 777 either has to put a comment into @file{foobar/autogen.sh} saying
 778 ``Attention! This doesn't work with a pristine Gnulib, you need this
 779 and that patch after checking out Gnulib,'' or it has to use the
 780 @samp{--avoid=stdint} option and provide the modified @code{stdint}
 781 module in a different directory.
 782
 783 The @option{--local-dir} option to @command{gnulib-tool} solves this
 784 problem.  It allows the package to override or augment Gnulib.  This
 785 means:
 786
 787 @itemize @bullet
 788 @item
 789 You can store files that are to override Gnulib files or modules.
 790
 791 @item
 792 You can store context diffs to be applied to Gnulib files.
 793
 794 @item
 795 You can add modules of your own, that are not (yet) in Gnulib.
 796
 797 @item
 798 You can also add unstructured amounts of code to the library, by
 799 grouping the non-Gnulib files of the library in a single kitchen-sink
 800 ``module.''  (This kind of kitchen-sink module is not needed when you
 801 use the @command{gnulib-tool} option @option{--makefile-name}.)
 802 @end itemize
 803
 804 In a release tarball, you can distribute the contents of this
 805 @option{--local-dir} directory that will be combinable with newer
 806 versions of Gnulib, barring incompatible changes to Gnulib.
 807
 808 If the @option{--local-dir=@var{directory}} option is specified, then
 809 @command{gnulib-tool} looks in @file{@var{directory}} whenever it
 810 reads a file from the Gnulib directory.  Suppose @command{gnulib-tool}
 811 is looking for @var{file}.  Then:
 812
 813 @itemize @bullet
 814 @item
 815 If @file{@var{directory}/@var{file}} exists, then @command{gnulib-tool} uses
 816 it instead of the file included in Gnulib.
 817
 818 @item
 819 Otherwise, if @file{@var{directory}/@var{file}.diff} exists, then
 820 @command{gnulib-tool} uses the file from Gnulib after applying the diff
 821 using the @command{patch} program.
 822
 823 @item
 824 Otherwise, @command{gnulib-tool} uses the file included in Gnulib.
 825 @end itemize
 826
 827 You can specify the @option{--local-dir} multiple times.  In this case,
 828 the first specified directory has the highest precedence.  That is, a
 829 @file{@var{file}} found in one directory will shadow any @file{@var{file}}
 830 and @file{@var{file}.diff} in the later directories and in the Gnulib
 831 directory.  And a file @file{@var{file}.diff} found in one directory will
 832 be applied on top of the combination of @file{@var{file}} and
 833 @file{@var{file}.diff} files found in the later directories and in the
 834 Gnulib directory.
 835
 836 Please make wise use of this option.  It also allows you to easily
 837 hold back modifications you make to Gnulib macros in cases it may be
 838 better to share them.

 870 @chapter Building the ISO C and POSIX Substitutes
 871
 872 This section shows a radically different way to use Gnulib.
 873
 874 You can extract the ISO C / POSIX substitutes part of gnulib by running
 875 the command
 876 @smallexample
 877 gnulib-tool --create-testdir --source-base=lib \
 878             --dir=/tmp/posixlib `posix-modules`
 879 @end smallexample
 880
 881 @noindent
 882 The command @samp{posix-modules} is found in the same directory as
 883 @code{gnulib-tool}.
 884
 885 The resulting directory can be built on a particular platform,
 886 independently of the program being ported.  Then you can configure and
 887 build any program, by setting @code{CPPFLAGS} and @code{LDFLAGS} at
 888 configure time accordingly: set @code{CPPFLAGS="-I.../posixlib/lib"}, plus
 889 any essential type definitions and flags that you find in
 890 @code{.../posixlib/config.h}, and set
 891 @code{LDFLAGS=".../posixlib/lib/libgnu.a"}.
 892
 893 This way of using Gnulib is useful when you don't want to modify the program's
 894 source code, or when the program uses a mix between C and C++ sources
 895 (requiring separate builds of the @code{posixlib} for the C compiler and
 896 for the C++ compiler).

 960 Gnulib module: nullptr
 961
 962 @cindex null pointer
 963 The @code{nullptr} module arranges for @code{nullptr} to act
 964 like standard C and C++.
 965
 966 The @code{nullptr} keyword yields a null pointer.  It differs from
 967 the @code{NULL} macro, in that @code{NULL} might be an integer whereas
 968 @code{nullptr} is of a special @code{nullptr_t} type with only one
 969 value, namely @code{nullptr} itself.  Using @code{nullptr} can help
 970 some compilers emit more sensible warnings, can avoid the need to cast
 971 a null pointer passed to a function prototyped with an ellipsis, and
 972 removes the need to include @code{<stddef.h>} merely to define
 973 @code{NULL}.
 974
 975 Portability problems fixed by Gnulib:
 976 @itemize
 977 @item
 978 Some platforms lack @code{nullptr}:
 979 For C: GCC 12, Clang 15, and other pre-2023 C compilers.
 980 For C++: pre-2011 C++ compilers.
 981 @end itemize
 982
 983 Portability problems not fixed by Gnulib:
 984 @itemize
 985 @item
 986 On older platforms, @code{nullptr} is a macro instead of a keyword.
 987
 988 @item
 989 On older platforms, @code{nullptr} does not have the type @code{nullptr_t}.
 990 In C, it has type @code{void *}; in C++ it has an integer type.
 991
 992 @item
 993 On older platforms Gnulib cannot easily emulate @code{nullptr_t}, so
 994 null pointer type checking is more error prone.  In C, @code{_Generic}
 995 expressions cannot reliably distinguish the type of @code{nullptr}
 996 from integer or @code{void *} types.  C++ overloading has similar
 997 limitations.

7087 Gnulib contains also a small number of files that are not part of
7088 modules.  They are meant to be imported into packages by means of
7089 @samp{gnulib-tool --copy-file}, not @samp{gnulib-tool --import}.  For
7090 example, the commands to import the files @code{config.guess} and

7163 These two scripts are necessary for supporting portability to native
7164 Windows with the MSVC compiler.  @code{compile} is a wrapper script that
7165 invokes the compiler and provides a command-line interface compatible
7166 with Unix compilers.  Similarly, @code{ar-lib} is a wrapper script that
7167 provides a command-line interface compatible with Unix @code{ar}.
7168 @item build-aux/depcomp
7169 This is a helper script, used by Makefile rules generated by GNU
7170 Automake.  It generates Makefile dependencies while compiling a file.
7171 @item build-aux/install-sh
7172 This is a helper script, used by Makefile rules generated by GNU
7173 Automake.  It installs files during the @code{make install} phase.  In
7174 the Makefile, don't use this file directly; always use
7175 @code{$(INSTALL_PROGRAM)} or @code{$(INSTALL_DATA)} instead.
7176 @item build-aux/mdate-sh
7177 This script determines the modification time of a file and pretty-prints
7178 it.  The typical use is to add a ``Last modified'' line to the
7179 documentation.
7180 @item build-aux/mkinstalldirs
7181 This is a helper script, used by Makefile rules generated by GNU
7182 Automake.  It creates directories during the @code{make install} phase.
7183 It is roughly equivalent to @samp{mkdir -p} (except that the latter is
7184 not portable).  In the Makefile, don't use this file directly; always
7185 use @code{$(MKDIR_P)} instead.
7186 @item build-aux/mktempd
7187 This script creates a temporary directory.  It is roughly equivalent to
7188 @samp{mktemp -d} (except that the latter is not portable).
7189 @item build-aux/move-if-change
7190 This script moves a freshly generated file to a destination file, with a
7191 special optimization for the case that both files are identical.  In
7192 this case the freshly generated file is deleted, and the time stamp of
7193 the destination file is @emph{not} changed.  This is useful when
7194 updating a file that rarely actually changes and which many Makefile
7195 targets depend upon.

7204 tools right away.

7207 @item top/gitsub.sh
7208 This program manages the subdirectories of a Git checkout that come from

7212 @itemx top/autopull.sh
7213 @itemx top/autogen.sh
7214 @itemx top/bootstrap-funclib.sh
7215 This is a set of three programs and a function library, that manage
7216 the source directory of a package, preparing for the state where
7217 @samp{./configure} can be used.
7218
7219 @code{autopull.sh} is a program for fetching dependencies that may
7220 require network accesses.  It manages the Git submodules, including
7221 Gnulib -- assuming that Gnulib is a Git submodule. It also can fetch
7222 the PO files for internationalized packages.
7223
7224 @code{autogen.sh} is a program that is meant to be run after
7225 @code{autopull.sh}.  It generates all autogeneratable files that are
7226 omitted from version control.  Usually this means that it invokes
7227 @code{gnulib-tool} and @code{automake}, that generate files from other
7228 files.
7229
7230 @code{bootstrap} is a wrapper around both:
7231 @code{./bootstrap --pull} is equivalent to @code{./autopull.sh},
7232 @code{./bootstrap --gen} is equivalent to @code{./autogen.sh}.
7233 Plain @code{./bootstrap} is equivalent to @code{./autopull.sh}
7234 immediately followed by @code{./autogen.sh}; however, because plain
7235 @code{./bootstrap} mixes version control management and
7236 generation of files in non-obvious ways, it has a number of usability
7237 issues for the advanced developer.
7238
7239 @code{bootstrap-funclib.sh} is a function library for these three
7240 programs.  It is not meant to be used directly.
7241
7242 All three programs make use of a configuration file, called
7243 @code{bootstrap.conf}.
7244
7245 @item build-aux/bootstrap
7246 This acts like @code{top/bootstrap}, except it does not
7247 need the companion files @code{autogen.sh},
7248 @code{autopull.sh}, and @code{bootstrap-funclib.sh}
7249 so it avoids some clutter in your project's top level directory.
7250 With this approach, you update via @code{./bootstrap --pull} and
7251 @code{./bootstrap --gen} instead of via @code{./autopull.sh} and
7252 @code{./autogen.sh}.  Otherwise this approach acts similarly, and
7253 uses the same @code{bootstrap.conf} file.
7254
7255 @item build-aux/bootstrap.conf
7256 This is the template configuration file.  After copying it into the
7257 top-level directory of your package, you need to customize it.
7258
7259 @item build-aux/po/Makefile.in.in
7260 @itemx build-aux/po/remove-potcdate.sin
7261 These are auxiliary files used by @code{bootstrap}.  You don't have to
7262 copy them yourself; @code{bootstrap} will do that.
