423: dnl This test is for network applications that need socket() and
424: dnl gethostbyname() -ish functions. Under Solaris, those applications
425: dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
426: dnl with "-lnsl" but should *not* link with "-lsocket" because
427: dnl libsocket.a breaks a number of things (for instance:
428: dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
429: dnl versions of IRIX).
430: dnl
431: dnl Unfortunately, many application developers are not aware of this,
432: dnl and mistakenly write tests that cause -lsocket to be used under
433: dnl IRIX. It is also easy to write tests that cause -lnsl to be used
434: dnl under operating systems where neither are necessary (or useful),
435: dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
436: dnl
437: dnl This test exists so that every application developer does not test
438: dnl this in a different, and subtly broken fashion.
439:
440: dnl It has been argued that this test should be broken up into two
441: dnl seperate tests, one for the resolver libraries, and one for the
442: dnl libraries necessary for using Sockets API. Unfortunately, the two
443: dnl are carefully intertwined and allowing the autoconf user to use
444: dnl them independantly potentially results in unfortunate ordering
445: dnl dependancies -- as such, such component macros would have to
446: dnl carefully use indirection and be aware if the other components were
447: dnl executed. Since other autoconf macros do not go to this trouble,
448: dnl and almost no applications use sockets without the resolver, this
449: dnl complexity has not been implemented.
450: dnl
451: dnl The check for libresolv is in case you are attempting to link

783: #
784: # Of course, Automake must honor this variable whenever it calls a
785: # tool from the auxiliary directory. The problem is that $srcdir (and
786: # therefore $ac_aux_dir as well) can be either absolute or relative,
787: # depending on how configure is run. This is pretty annoying, since
788: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
789: # source directory, any form will work fine, but in subdirectories a
790: # relative path needs to be adjusted first.
791: #
792: # $ac_aux_dir/missing
793: # fails when called from a subdirectory if $ac_aux_dir is relative
794: # $top_srcdir/$ac_aux_dir/missing
795: # fails if $ac_aux_dir is absolute,
796: # fails when called from a subdirectory in a VPATH build with
797: # a relative $ac_aux_dir
798: #
799: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
800: # are both prefixed by $srcdir. In an in-source build this is usually
801: # harmless because $srcdir is `.', but things will broke when you
802: # start a VPATH build or use an absolute $srcdir.
803: #
804: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
805: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
806: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
807: # and then we would define $MISSING as
808: # MISSING="\${SHELL} $am_aux_dir/missing"

811: # However there are other variables, like CC, which are often used in
812: # configure, and could therefore not use this "fixed" $ac_aux_dir.
813: #
814: # Another solution, used here, is to always expand $ac_aux_dir to an
815: # absolute PATH. The drawback is that using absolute paths prevent a
