From fbe7d8cbc5df572024098bfae2ad2666cd4bcc47 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Tue, 29 May 2007 11:13:07 +0000 Subject: r23188: revert 23123 and 23118. as a long term solution this was the correct approach, but it's a bit more complex and we need to provide the whole socket api and libnsl.so checking in libreplace... as a short term solution to fix the build on host 'hape' we'll use the same trick as with inet_aton.c from heimdal's lib/roken/ metze (This used to be commit 0e88e2e46199d8ea64dd42c4c8b86d64ce5c2d04) --- source4/lib/replace/README | 2 - source4/lib/replace/inet.m4 | 2 - source4/lib/replace/inet_ntop.c | 188 --------------------------------- source4/lib/replace/inet_pton.c | 215 -------------------------------------- source4/lib/replace/libreplace.m4 | 1 - source4/lib/replace/replace.h | 10 -- 6 files changed, 418 deletions(-) delete mode 100644 source4/lib/replace/inet.m4 delete mode 100644 source4/lib/replace/inet_ntop.c delete mode 100644 source4/lib/replace/inet_pton.c diff --git a/source4/lib/replace/README b/source4/lib/replace/README index 3ce1d61e82..77558b2ca9 100644 --- a/source4/lib/replace/README +++ b/source4/lib/replace/README @@ -54,8 +54,6 @@ strtoll strtoull socketpair strptime -inet_pton -inet_ntop Types: bool diff --git a/source4/lib/replace/inet.m4 b/source4/lib/replace/inet.m4 deleted file mode 100644 index bbb205dc3e..0000000000 --- a/source4/lib/replace/inet.m4 +++ /dev/null @@ -1,2 +0,0 @@ -AC_CHECK_FUNCS(inet_pton,[],[LIBREPLACEOBJ="${LIBREPLACEOBJ} inet_pton.o"]) -AC_CHECK_FUNCS(inet_ntop,[],[LIBREPLACEOBJ="${LIBREPLACEOBJ} inet_ntop.o"]) diff --git a/source4/lib/replace/inet_ntop.c b/source4/lib/replace/inet_ntop.c deleted file mode 100644 index 3f3e6f87d4..0000000000 --- a/source4/lib/replace/inet_ntop.c +++ /dev/null @@ -1,188 +0,0 @@ -/* - * Copyright (C) 1996-2001 Internet Software Consortium. - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND INTERNET SOFTWARE CONSORTIUM - * DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL - * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS.
