-Many of the files in this directory are shared between the diffutils,
-fileutils, sh-utils, and textutils packages -- and others, so if you
+Many of the files in this directory are shared between the coreutils,
+diffutils, tar and gettext packages -- and others, so if you
change them, try to ensure that you don't break those packages.
-Unfortunately, that's hard.
-
-One way to do that is to put the modified .m4 file in each of the packages,
-run `make dist' to create a .tar.gz file, then build that package on as
-many different types of systems as possible. Then repeat, but using the
-original version of the .m4 file. Run configure like this each time
-`./configure --cache=config.cache' and be sure to save the following files
-from each run: config.cache config.status config.out config.h*.
-Then compare the two versions of each of those files and be prepared to
-explain any differences.
-
-These files are used by a program called aclocal (part of the GNU automake
-package). aclocal uses these files to create aclocal.m4 which is in turn
-used by autoconf to create the configure script at the top level in
-this distribution.
+That's hard without a systematic approach, but here is a set of conventions
+that makes it easy.
+
+- The lib/ sources are split into modules. Usually the module of a
+ lib/foo.h and lib/foo.c is called "foo" - not unexpected, hey! -, but
+ in more ambiguous cases you can look up the module a file belongs to
+ by doing "grep lib/foo.c modules/*".
+
+- For every module there is an autoconf macro file, usually called
+ m4/foo.m4 according to the module name. When you modify lib/foo.h or
+ lib/foo.c, remember to modify m4/foo.m4 as well!
+ What if you don't find m4/foo.m4? This probably means that the module
+ doesn't need autoconf support up to now (again, take a look in modules/*).
+ So you might need to create one.
+
+- A module which defines a replacement function (i.e. a function which is
+ compiled only on systems which lack it or where it exists but doesn't
+ work satisfactorily) has a .m4 file with typically the following structure:
+
+ AC_DEFUN([gl_FUNC_FOO],
+ [
+ AC_REPLACE_FUNCS(foo)
+ if test $ac_cv_func_foo = no; then
+ gl_PREREQ_FOO
+ fi
+ ])
+
+ # Prerequisites of lib/foo.c.
+ AC_DEFUN([gl_PREREQ_FOO], [
+ dnl Many AC_CHECK_* invocations.
+ ])
+
+- A module which is compiled on all platforms can define multiple functions
+ and be spread across multiple source files (although each time you do
+ this you should consider splitting the module, if the source files could
+ be independent). The .m4 file has typically the following structure:
+
+ AC_DEFUN([gl_FOO],
+ [
+ dnl Prerequisites of lib/foo.c.
+ dnl Many AC_CHECK_* invocations.
+
+ dnl Prerequisites of lib/foobar.c.
+ dnl Many AC_CHECK_* invocations.
+ ])
+
+- When a module FOO depends on a module BAR, you do *not* generally need
+ to write
+
+ AC_DEFUN([gl_FOO],
+ [
+ AC_REQUIRE([gl_BAR])
+ ...
+ ])
+
+ because the maintainers might want to use locally modified / renamed copies
+ of the module BAR.
+
+- If the autoconf tests for the modules FOO and BAR have some checks in
+ common, still list them separately. Autoconf has two mechanisms for
+ avoiding that a configure file runs the same test twice: AC_REQUIRE
+ and AC_CACHE_CHECK. Trying to omit the checks leads to maintenance
+ problems: If FOO depends on BAR, and you omit a check from FOO's .m4 file,
+ later on, when someone modifies bar.c and removes the check from bar.m4,
+ he will not remember that foo.c needs the check as well.
+
+- Now, how can you find the prerequisites of lib/foo.c? Try this:
+ "grep '#.*if' lib/foo.c | grep -v endif"
+ and for each HAVE_* macro search in the autoconf documentation what could
+ be the autoconf macro that provides it. This is only an approximation; in
+ general you should look at all preprocessor directives in lib/foo.c.
+
+- After ANY modifications of an m4 file, you should increment its serial
+ number (in the first line). Also, if this first line features a particular
+ release, _remove_ this release stamp. Example: Change
+
+ # setenv.m4 serial 2 (gettext-0.11.1)
+
+ into
+
+ # setenv.m4 serial 3
+
# Written by Paul Eggert.
