 267 dnl This test is for network applications that need socket() and
 268 dnl gethostbyname() -ish functions.  Under Solaris, those applications
 269 dnl need to link with "-lsocket -lnsl".  Under IRIX, they need to link
 270 dnl with "-lnsl" but should *not* link with "-lsocket" because
 271 dnl libsocket.a breaks a number of things (for instance:
 272 dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
 273 dnl versions of IRIX).
 274 dnl
 275 dnl Unfortunately, many application developers are not aware of this,
 276 dnl and mistakenly write tests that cause -lsocket to be used under
 277 dnl IRIX.  It is also easy to write tests that cause -lnsl to be used
 278 dnl under operating systems where neither are necessary (or useful),
 279 dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
 280 dnl
 281 dnl This test exists so that every application developer does not test
 282 dnl this in a different, and subtly broken fashion.
 283
 284 dnl It has been argued that this test should be broken up into two
 285 dnl seperate tests, one for the resolver libraries, and one for the
 286 dnl libraries necessary for using Sockets API. Unfortunately, the two
 287 dnl are carefully intertwined and allowing the autoconf user to use
 288 dnl them independantly potentially results in unfortunate ordering
 289 dnl dependancies -- as such, such component macros would have to
 290 dnl carefully use indirection and be aware if the other components were
 291 dnl executed. Since other autoconf macros do not go to this trouble,
 292 dnl and almost no applications use sockets without the resolver, this
 293 dnl complexity has not been implemented.
 294 dnl
 295 dnl The check for libresolv is in case you are attempting to link
 296 dnl statically and happen to have a libresolv.a lying around (and no
 297 dnl libnsl.a).
