2 * The NEWS file is more verbose.
4 * Defining programs conditionally using Automake conditionals
5 no longer leads to a combinatorial explosion. The following
6 construct used to be troublesome when used with dozens
21 Likewise for _LDADD and _LIBADD variables.
23 * Automake now supports bin_PROGRAMS (or any *_PROGRAMS variable)
24 being defined in several conditions. As in
33 Likewise for _LDADD and _LIBADD variables.
35 * install-sh now understands --version and --help.
37 * Cleanup the definitions of $(distdir) and $(top_distdir).
38 $(top_distdir) now points to the root of the distribution directory
39 created during `make dist', as it did in Automake 1.4, not to the
40 root of the build tree as it did in intervening versions.
41 Furthermore these two variables are now only defined in the top
42 level Makefile, and passed to sub-directories when running `make dist'.
44 * elisp sources are compiled all at once, instead of one by one.
45 This allows interdependencies and speeds up compilation.
47 * AM_PROG_CC_STDC is now empty. The content of this macro was
48 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc,
49 you should adjust it to use $ac_cv_prog_cc_stdc instead.
50 (This renaming should be safe, even if you have to support several,
51 versions of Automake, because AC_PROG_CC defines this variable since
56 * Autoconf 2.54 is required.
57 * `aclocal' and `automake' will no longer warn about obsolete
58 configure macros. This is done by `autoconf -Wobsolete'.
59 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
60 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
61 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
62 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
63 `configure.ac' for you.
64 * Support for per-program and per-library `_CPPFLAGS'.
65 * New `ctags' target (builds CTAGS files).
66 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
67 (see `automake --help' or the manual for a list of them).
68 * Honor the WARNINGS environment variable.
69 * Omit the call to depcomp when using gcc3: call the compiler directly.
70 * A new option, std-options, tests that programs support --help and --version
71 when `make installcheck' is run. This is enabled by --gnits.
72 * Texinfo rules now support the `ps' and `pdf' targets.
73 * Info files are now created in the build directory, not the source directory.
74 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
76 * `make distcheck' will enforce DESTDIR support by attempting
78 * `+=' can be used in conditionals, even if the augmented variable
79 was defined for another condition.
80 * Makefile fragments (inserted with `include') are always distributed.
81 * Use Autoconf's --trace interface to inspect configure.ac and get
82 a more accurate view of it.
83 * Add support for extending aclocal's default macro search path
84 using a `dirlist' file within the aclocal directory.
85 * automake --output-dir is deprecated.
86 * The part of the distcheck target that checks whether uninstall actually
87 removes all installed files has been moved in a separate target,
88 distuninstallcheck, so it can be overridden easily.
92 * Autoconf 2.52 is required.
93 * automake no longer run libtoolize.
94 This is the job of autoreconf (from GNU Autoconf).
95 * `dist' generates all the archive flavors, as did `dist-all'.
96 * `dist-gzip' generates the Gzip tar file only.
97 * Combining Automake Makefile conditionals no longer lead to a combinatorial
98 explosion. Makefile.in's keep a reasonable size.
99 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
100 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
102 * `#line' of Lex and Yacc files are properly set.
103 * EXTRA_DIST can contain generated directories.
104 * Support for dot-less extensions in suffix rules.
105 * The part of the distcheck target that checks whether distclean actually
106 cleans all built files has been moved in a separate target, distcleancheck,
107 so it can be overridden easily.
108 * `make distcheck' will pass additional options defined in
109 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
110 * Fixed CDPATH portability problems, in particular for MacOS X.
111 * Fixed handling of nobase_ targets.
112 * Fixed support of implicit rules leading to .lo objects.
113 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
114 * Added uninstall-hook target
115 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
116 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
117 (Note that "pkgname" is not "tarname", see the manual for details.)
118 It is also possible to pass a list of global Automake options as
119 first argument to this new form of AM_INIT_AUTOMAKE.
120 * Compiler-based assembler is now called `CCAS'; people expected `AS'
121 to be a real assembler.
122 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
123 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
124 * aclocal and automake are also installed with the version number
125 appended, and some of the install directory names have changed.
126 This lets you have multiple versions installed simultaneously.
127 * Support for parsers and lexers in subdirectories.
130 * Support for `configure.ac'.
131 * Support for `else COND', `endif COND' and negated conditions `!COND'.
132 * `make dist-all' is much faster.
133 * Allows '@' AC_SUBSTs in macro names.
134 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
135 * User-side dependency tracking. Developers no longer need GNU make
137 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
138 * Most files are correctly handled if they appear in subdirs
139 For instance, a _DATA file can appear in a subdir

148 * Added support for the Fortran 77 programming language.
149 * Re-indexed the Automake Texinfo manual.
150 * Added `AM_FOOFLAGS' variable for each compiler invocation;
151 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
152 * Support for latest autoconf, including support for objext
153 * Can now put `.' in SUBDIRS to control build order
154 * `include' command and `+=' support for macro assignment
155 * Dependency tracking no long susceptible to deleted header file problem
156 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
161 * Better Cygwin32 support
162 * Support for suffix rules with _SOURCES variables
163 * New options `readme-alpha' and `check-news'; Gnits mode sets these
164 * @LEXLIB@ no longer required when lex source seen
165 Lex support in `missing', and new lex macro. Update your missing script.
166 * Built-in support for assembly
167 * aclocal gives error if `AM_' macro not found
168 * Passed YFLAGS, not YACCFLAGS, to yacc

186 * Better C++, yacc, lex support
187 * Will compute _DEPENDENCIES variables automatically if not supplied
