Automake will generate rules to automatically regenerate the config header. If you do use this macro, you must create the file stamp-h.in in your source directory. It can be empty.
This is used when a "multilib" library is being built. The first optional argument is the name of the Makefile being generated; it defaults to Makefile. The second option argument is used to find the top source directory; it defaults to the empty string (generally this should not be used unless you are familiar with the internals). the section called “Support for Multilibs”.
These macros are used to implement automake's automatic dependency tracking scheme. They are called automatically by automake when required, and there should be no need to invoke them manually.
If the strtod function is not available, or does not work correctly (like the one on SunOS 5.4), add strtod.o to output variable LIBOBJS.
If the function error_at_line is not found, then add error.o to LIBOBJS.
Check for the GNU obstacks code; if not found, add obstack.o to LIBOBJS.
Check to see if function prototypes are understood by the compiler. If so, define PROTOTYPES and set the output variables U and ANSI2KNR to the empty string. Otherwise, set U to _ and ANSI2KNR to ./ansi2knr. Automake uses these values to implement automatic de-ANSI-fication.
If the use of TIOCGWINSZ requires sys/ioctl.h, then define GWINSZ_IN_SYS_IOCTL. Otherwise TIOCGWINSZ can be found in termios.h.
Runs many macros that most configure.in's need. This macro has two required arguments, the package and the version number. By default this macro AC_DEFINE's PACKAGE and VERSION. This can be avoided by passing in a non-empty third argument.
This macro is used to discover how the user's make handles include statements. This macro is automatically invoked when needed; there should be no need to invoke it manually.
Searches for the program emacs, and, if found, sets the output variable lispdir to the full path to Emacs' site-lisp directory.
Use this macro when you have assembly code in your project. This will choose the assembler for you (by default the C compiler), and will set ASFLAGS if required.
This is like AC_PROG_CC_C_O, but it generates its results in the manner required by automake. You must use this instead of AC_PROG_CC_C_O when you need this functionality.
If the C compiler in not in ANSI C mode by default, try to add an option to output variable CC to make it so. This macro tries various options that select ANSI C on some system or another. It considers the compiler to be in ANSI C mode if it handles function prototypes correctly.
If you use this macro, you should check after calling it whether the C compiler has been set to accept ANSI C; if not, the shell variable am_cv_prog_cc_stdc is set to no. If you wrote your source code in ANSI C, you can make an un-ANSIfied copy of it by using the ansi2knr option (the section called “Automatic de-ANSI-fication”).
Like AC_PROG_LEX with AC_DECL_YYTEXT (), but uses the missing script on systems that do not have lex. HP-UX 10 is one such system.
Autoconf 2.50 and higher, in order to simplify the interface, includes the body of AC_DECL_YYTEXT in AC_PROG_LEX. To ensure backward compatibility, AC_DECL_YYTEXT is nevertheless defined as an invocation of AC_PROG_LEX. Since AM_PROG_LEX invokes both, it causes an annoying but benign warning (AC_PROG_LEX invoked multiple times) which you should just ignore. In the future, once Automake requires Autoconf 2.50, this issue will be fixed, but the current compatibility with Autoconf 2.13 prevents this.
This macro finds the gcj program or causes an error. It sets GCJ and GCJFLAGS. gcj is the Java front-end to the GNU Compiler Collection.
This is used to find a version of install which can be used to strip a program at installation time. This macro is automatically included when required.
This checks to make sure that a file created in the build directory is newer than a file in the source directory. This can fail on systems where the clock is set incorrectly. This macro is automatically run from AM_INIT_AUTOMAKE.
Check to see if POSIX termios headers and functions are available on the system. If so, set the shell variable am_cv_sys_posix_termios to yes. If not, set the variable to no.
Define HAVE_PTRDIFF_T if the type ptrdiff_t is defined in stddef.h.
Add support for the ftp://ftp.letters.com/src/dmalloc/dmalloc.tar.gzdmalloc package. If the user configures with -with-dmalloc, then define WITH_DMALLOC and add -ldmalloc to LIBS.
Adds -with-regex to the configure command line. If specified (the default), then the regex regular expression library is used, regex.o is put into LIBOBJS, and WITH_REGEX is defined.. If -without-regex is given, then the rx regular expression library is used, and rx.o is put into LIBOBJS.
