使用Android NDK构建共享库-未定义的引用

Question

我正在尝试建立一个共享库，可以用来访问本机蓝牙API函数。我目前正试图编译一个c文件：https://android.googlesource.com/platform/external/bluetooth/bluedroid/

每当我尝试将这些代码中的任何一个编译为共享库时，我都会收到许多未定义的引用错误...它看起来像是头文件引用的每个函数。在我最近的尝试中，我将整个Bluedroid/bta文件复制到我的eclipse project/jni文件夹中。使用包含的Android.mk，只需最少的修改，我就可以编译为静态库。但是，如果我将行更改为：
include$（BUILD_STATIC_LIBRARY）
to
include$（BUILD_SHARED_LIBRARY）

我犯了很多错误。我该如何构建共享图书馆？

这是我的Android。mk:

Answer 1

在Android中。mksetlocal\u allow\u undefined\u符号：=true。

Answer 2

NDK不使用cygwin，无法识别cygdrive路径；将其更改为c:/adev/bluedroid或类似。
