我正在尝试使用Android NDK为我的项目构建GnuTLS for Android。我在how libffmpeg is compile using Android NDK上看到了一些示例，并将OpenSSL移植到Android。 GnuTLS也可以吗？
我尝试使用Android NDK r7b编译GnuTLS soruce但没有结果，有些文件只是拒绝编译。我是否需要删除某些功能，或者有任何方法可以删除吗？希望对此提出一些建议。提前谢谢。

在我的Ubuntu系统上编译时，我正在使用以下Android.mk文件和源文件的顺序，这些文件基于命令make的输出：

我现在在做什么有问题吗？我是否需要更改任何内容以便ndk-build能够编译？
