dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
|
|
dnl with "-lnsl" but should *not* link with "-lsocket" because
|
|
dnl libsocket.a breaks a number of things (for instance:
|
|
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
|
|
dnl versions of IRIX).
|
|
dnl
|
|
dnl Unfortunately, many application developers are not aware of this,
|
|
dnl and mistakenly write tests that cause -lsocket to be used under
|
|
dnl IRIX. It is also easy to write tests that cause -lnsl to be used
|
|
dnl under operating systems where neither are necessary (or useful),
|
|
dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
|
|
dnl
|
|
dnl This test exists so that every application developer does not test
|
|
dnl this in a different, and subtly broken fashion.
|
|
|
|
dnl It has been argued that this test should be broken up into two
|
|
dnl seperate tests, one for the resolver libraries, and one for the
|
|
dnl libraries necessary for using Sockets API. Unfortunately, the two
|
|
dnl are carefully intertwined and allowing the autoconf user to use
|
|
dnl them independantly potentially results in unfortunate ordering
|
|
dnl dependancies -- as such, such component macros would have to
|
|
dnl carefully use indirection and be aware if the other components were
|
|
dnl executed. Since other autoconf macros do not go to this trouble,
|
|
dnl and almost no applications use sockets without the resolver, this
|
|
dnl complexity has not been implemented.
|
|
dnl
|
|
dnl The check for libresolv is in case you are attempting to link
|
|
dnl statically and happen to have a libresolv.a lying around (and no
