我想要申请这个补丁所以我复制了从“Index: src/options.h”开始并以“+@item”结束的代码，并将其放入在wget源代码文件夹中创建的新文件中。然后我做了：
$ patch -p0 < name_of_patch
(Patch is indented 1 space.)
patching file src/options.h
patch: **** malformed patch at line 6: char **excludes; /* List of excluded FTP directories. */
我应该如何应用这个？

答案1
这是复制/粘贴到没有空格缩进的文本文件中的差异的常见问题。您需要在每行前面添加空格，以符号“+”、“-”和“@@”开头的行除外。为了避免这个问题，最好自己手动生成 diff 文件（使用diff版本控制 diff 工具），然后下载整个 diff 文件，而不是从浏览器复制和粘贴。
我建议在应用补丁之前，检查补丁是否已在上游，并且在更新/最新/稳定版本中可用，这将以干净的方式解决您的问题。即使您修补了该.c文件，无论如何您都会编译它，所以如果补丁已进入上游，为什么不使用新的稳定的 tarball 来进行编译呢？
答案2
我赞同尼基尔的一般性评论。不过，我只想指出，通常最好下载 html 文件，然后将其转换为文本，而不是使用剪切和粘贴。例如，你可以这样做
1）wget-chttp://osdir.com/ml/web.wget.patches/2007-07/msg00011.html
2) 以Openoffice为例，打开msg00011.html。并另存为文本。 OO 转换器做得很好，我没有发现转换后的补丁有任何明显的问题。
