From e658892793c42b2d058eed0937025ef2ddaaa372 Mon Sep 17 00:00:00 2001 From: jin-eld Date: Sun, 4 Aug 2013 15:10:37 +0300 Subject: Rename core directory because of autoconf name clash While doing the checks configure might generate "core" files and will then try to remove them. Having a "core" directory generates an error while runing the configure script. There's no workaround but to rename the core directory. --- core/DHT.h | 193 ------------------------------------------------------------- 1 file changed, 193 deletions(-) delete mode 100644 core/DHT.h (limited to 'core/DHT.h') diff --git a/core/DHT.h b/core/DHT.h deleted file mode 100644 index 6295581b..00000000 --- a/core/DHT.h +++ /dev/null @@ -1,193 +0,0 @@ -/* DHT.h - * - * An implementation of the DHT as seen in http://wiki.tox.im/index.php/DHT - * - * Copyright (C) 2013 Tox project All Rights Reserved. - * - * This file is part of Tox. - * - * Tox is free software: you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * Tox is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
