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