765 dnl behind the fixed sized types; the "least" and "fast" types are still being

773 dnl Written by John Hawkinson <jhawk@mit.edu>. This code is in the Public
774 dnl Domain.
775 dnl
776 dnl This test is for network applications that need socket() and
777 dnl gethostbyname() -ish functions. Under Solaris, those applications need to
778 dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with
779 dnl "-lsocket" because libsocket.a breaks a number of things (for instance:
780 dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of
781 dnl IRIX).
782 dnl
783 dnl Unfortunately, many application developers are not aware of this, and
784 dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
785 dnl also easy to write tests that cause -lnsl to be used under operating
786 dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
787 dnl uses -lnsl for TLI.
788 dnl
789 dnl This test exists so that every application developer does not test this in
790 dnl a different, and subtly broken fashion.
791 dnl
792 dnl It has been argued that this test should be broken up into two seperate
793 dnl tests, one for the resolver libraries, and one for the libraries necessary
794 dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
795 dnl allowing the autoconf user to use them independantly potentially results in
796 dnl unfortunate ordering dependancies -- as such, such component macros would
797 dnl have to carefully use indirection and be aware if the other components were
798 dnl executed. Since other autoconf macros do not go to this trouble, and almost
799 dnl no applications use sockets without the resolver, this complexity has not
800 dnl been implemented.
801 dnl
802 dnl The check for libresolv is in case you are attempting to link statically
803 dnl and happen to have a libresolv.a lying around (and no libnsl.a).

832 dnl
833 dnl Creates a custom LIBRARY-config script. The script supports
834 dnl --cflags, --libs and --version options, as well as all of the
835 dnl standard configure variables e.g. --libdir and --sysconfdir.
836 dnl --prefix and --exec-prefix may be specified to override the
837 dnl defaults. --help gives a complete list of available options.
838 dnl Modules allow multiple sets of --libs, --cflags and --version
839 dnl options to be used, and combined together.
840 dnl
841 dnl This macro saves you all the typing for a library-config.in script;
842 dnl you don't even need to distribute one along. Place this macro
843 dnl in your configure.ac, et voila, you got one that you want to install.
844 dnl
845 dnl The options:
846 dnl
847 dnl $1 = LIBRARY e.g. gtk, ncurses
848 dnl $2 = DESTINATION Directory path, e.g. src/scripts
849 dnl $3 = MODULES Additional library modules, not including the
850 dnl default ($1).
851 dnl
852 dnl It is suggested that the following CFLAGS and LIBS variables are
853 dnl used in your configure.in. library_libs is *essential*.
854 dnl library_cflags is important, but not always needed. If they do not
855 dnl exist, defaults will be taken from LIBRARY_CFLAGS, LIBRARY_LIBS
856 dnl (should be -llibrary *only*) and LIBRARY_LIBDEPS (-l options for
857 dnl libraries your library depends upon.
858 dnl LIBLIBRARY_LIBS is simply $LIBRARY_LIBS $LIBRARY_LIBDEPS.
859 dnl NB. LIBRARY and library are the name of your library, in upper and
860 dnl lower case repectively e.g. GTK, gtk.
861 dnl
862 dnl LIBRARY_CFLAGS: cflags for compiling libraries and example progs
863 dnl LIBRARY_LIBS: libraries for linking programs
864 dnl LIBRARY_LIBDEPS*: libraries for linking libraries against (needed
865 dnl to link -static
866 dnl library_cflags*: cflags to store in library-config
867 dnl library_libs*: libs to store in library-config
868 dnl LIBLIBRARY_LIBS: libs to link programs IN THIS PACKAGE ONLY against
869 dnl LIBRARY_VERSION*: the version of your library (x.y.z recommended)
870 dnl *=required if you want sensible output, otherwise they will be
871 dnl *guessed* (DWIM)
872 dnl
873 dnl Support for pkg-config is available by default. libs, cflags and
874 dnl version information will be obtained from the pkg-config metadata
875 dnl file library.pc if it exists in the pkgconfig data directory.
876 dnl The above information still needs to be specified, as it will still
877 dnl be used if pkg-config is not found on the host system at configure
878 dnl time.
879 dnl
880 dnl -I and -L flags will be obtained from *both* pkgconfig and the script.
881 dnl AC_CONFIG_LIBCONFIG_IN_PKGCONFIG enables pkg-config support (default)
882 dnl AC_CONFIG_LIBCONFIG_IN_STATIC disables pkg-config support
883 dnl
884 dnl There is also an AC_SUBST(LIBRARY_CONFIG) that will be set to
885 dnl the name of the file that we output in this macro. Use as:
886 dnl
887 dnl install-exec-local: install-config
888 dnl install-config:
889 dnl $(mkinstalldirs) $(DESTDIR)$(bindir)
890 dnl $(INSTALL_EXEC) @LIBRARY_CONFIG@ $(DESTDIR)$(bindir)
891 dnl
892 dnl Or, if using automake:
893 dnl
894 dnl bin_SCRIPTS = @LIBRARY_CONFIG@
895 dnl
896 dnl Based upon AC_CREATE_GENERIC_CONFIG (ac_create_generic_config.m4)
