Under Solaris, those applications +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 +dnl libnsl.a). +dnl +AC_DEFUN(AC_LBL_LIBRARY_NET, [ + # Most operating systems have gethostbyname() in the default searched + # libraries (i.e. libc): + AC_CHECK_FUNC(gethostbyname, , + # Some OSes (eg.
