26 dnl Do whatever AC_LBL_C_INIT work is necessary before using AC_PROG_CC.

28 dnl It appears that newer versions of autoconf (2.64 and later) will,
29 dnl if you use AC_TRY_COMPILE in a macro, stick AC_PROG_CC at the
30 dnl beginning of the macro, even if the macro itself calls AC_PROG_CC.
31 dnl See the "Prerequisite Macros" and "Expanded Before Required" sections
32 dnl in the Autoconf documentation.

34 dnl This causes a steaming heap of fail in our case, as we were, in
35 dnl AC_LBL_C_INIT, doing the tests we now do in AC_LBL_C_INIT_BEFORE_CC,
36 dnl calling AC_PROG_CC, and then doing the tests we now do in
37 dnl AC_LBL_C_INIT. Now, we run AC_LBL_C_INIT_BEFORE_CC, AC_PROG_CC,
38 dnl and AC_LBL_C_INIT at the top level.

915 dnl This test is for network applications that need socket() and

917 dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
918 dnl with "-lnsl" but should *not* link with "-lsocket" because
919 dnl libsocket.a breaks a number of things (for instance:
920 dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
921 dnl versions of IRIX).
922 dnl
923 dnl Unfortunately, many application developers are not aware of this,
924 dnl and mistakenly write tests that cause -lsocket to be used under
925 dnl IRIX. It is also easy to write tests that cause -lnsl to be used
926 dnl under operating systems where neither are necessary (or useful),
927 dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
928 dnl
929 dnl This test exists so that every application developer does not test
930 dnl this in a different, and subtly broken fashion.
931
932 dnl It has been argued that this test should be broken up into two
933 dnl seperate tests, one for the resolver libraries, and one for the
934 dnl libraries necessary for using Sockets API. Unfortunately, the two
935 dnl are carefully intertwined and allowing the autoconf user to use
936 dnl them independantly potentially results in unfortunate ordering
937 dnl dependancies -- as such, such component macros would have to
938 dnl carefully use indirection and be aware if the other components were
939 dnl executed. Since other autoconf macros do not go to this trouble,
940 dnl and almost no applications use sockets without the resolver, this
941 dnl complexity has not been implemented.
942 dnl
943 dnl The check for libresolv is in case you are attempting to link
