1352 dnl This test is for network applications that need socket() and
1353 dnl gethostbyname() -ish functions. Under Solaris, those applications need to
1354 dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with
1355 dnl "-lsocket" because libsocket.a breaks a number of things (for instance:
1356 dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of
1359 dnl Unfortunately, many application developers are not aware of this, and
1360 dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
1361 dnl also easy to write tests that cause -lnsl to be used under operating
1362 dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
1363 dnl uses -lnsl for TLI.
1365 dnl This test exists so that every application developer does not test this in
1366 dnl a different, and subtly broken fashion.
1368 dnl It has been argued that this test should be broken up into two seperate
1369 dnl tests, one for the resolver libraries, and one for the libraries necessary
1370 dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
1371 dnl allowing the autoconf user to use them independantly potentially results in
1372 dnl unfortunate ordering dependancies -- as such, such component macros would
1373 dnl have to carefully use indirection and be aware if the other components were
1374 dnl executed. Since other autoconf macros do not go to this trouble, and almost
1375 dnl no applications use sockets without the resolver, this complexity has not
1376 dnl been implemented.
1378 dnl The check for libresolv is in case you are attempting to link statically
1379 dnl and happen to have a libresolv.a lying around (and no libnsl.a).
