请在底部看到附加内容!第一个问题在Linux中解决,而不是在Windows和Cygwin下,但是还有一个新问题。请看下面!在Android NDK中编译OpenCV
我目前正在尝试为Android NDK编译OpenCV,以便我可以在我的应用程序中使用它。为此,我试图按照本指南:
http://www.stanford.edu/~zxwang/android_opencv.html
但随着NDK建造编译下载的东西,当我得到这个错误:

我试图编译它在Windows系统上并与最新的NDK版本...
有没有人有一个想法这个链接错误意味着什么,我可以让它再次工作?
将是巨大的,如果有人可以帮助
得到问题的工作,我发现,有编制的OpenCV的Android使用的OpenCV的当前版本(而不是1.1一个从另一种方式后以上)以及来自crystax的修改的Android NDK,它支持STL和异常,因此支持最新的OpenCV版本。
的所有信息上可以在这里找到: http://opencv.willowgarage.com/wiki/Android
有它说下载当前SVN主干和crystax-R4的Android NDK,以及痛饮,我做到了。
我进入了文件夹,创建了构建目录,运行cmake,然后构建了静态库,这似乎工作。至少它成功运行make-command而没有错误。
我现在想建立的共享库,所以我进入了Android的JNI文件夹,并跑了“使”了,但得到这个错误:

没有任何人有一个想法,这是什么意思,什么我可以做建立共享库吗?
...
确定在看看它来找我,它似乎有东西在build目录中缺少......但没有连build目录在Android的错误消息后文件夹,所以我创建了一个,在那里跑“cmake的”和“做”了,但得到这个错误:

任何人都知道这意味着什么?
我有这个文件,它包含:target = android-3 ...可能是一个问题,我正在使用WIndows呢?所以这可能是缺少的东西,通常会自动包含在Linux中? – evident
怎么样尝试android-8? –
你已经建立了它正在寻找的库。我想知道如果不同的平台正在改变你的Android.mk被解释的方式。 –
