****这个问题是关于从 ndk-build 调用 make trace 选项*********
我正在尝试通过 make 文件进行跟踪，但出现错误。我的理解是ndk是shell，它调用make。所以我应该能够调用 make 开关；我可以做其中的一些。但是跟踪选项不起作用：-（请参阅下面的输出；我做错了什么？
@MadScientist - 我下载并安装了 4.0 版。但我仍然看到同样的错误。任何人都可以在他们的系统上运行它，并发布他们使用的命令吗？我想我可能会触发开关故障或其他什么。如果我能看到一个工作实例，我可以从那里微调命令。还; 我查看了您发布的 make-4.0 更新链接；那里也列出了调试。Sooo 我不确定为什么或如何调试 3.81；也许它的早期版本。另外我不确定为什么调试有效但不跟踪。我认为这是一个ndk问题。我所做的是直接发出 make ，不仅我看到跟踪工作；我没有看到促使我发布此问题的错误。这是所有与“：”和“：：”一起使用的抱怨。

@Alex Cohn - 再次感谢。这解释了很多。我将首先考虑获取最新的ndk；然后尝试使用最新版本的make。对我来说，一个悬而未决的问题是，我试图移植到 jni 中的本机 C 项目使用 ndk 早期版本中的工具链之一进行编译。因此，对我来说，现在收到“::”错误消息似乎表明它是由其他原因引起的。我怀疑这与我试图将 C 项目的 make 文件包含到我的 Android.mk 中有关。虽然我的 Android.mk 没有一个 all 目标，但也许有一个暗示？我只是像报纸一样阅读了一次制作手册；我不记得是不是这样。但是有很多隐含的规则。你对此有什么想法吗？
