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.

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.
