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