我有一个 Android 本机代码，它由一个静态库（XXX.a）和最终的 ndk-build 命令（NDK_DEBUG 设置为 1）采用上述预构建的静态库并创建一个共享对象。
我使用 nm 命令查看特定函数定义的共享对象，它似乎可用（001ff2f5 T XXXXX）。
但是当我在运行 4.4.2 的 Android 设备上运行 ndk-gdb 时，gdb 无法加载共享对象符号：

我在 Ubuntu、ndk-r8 NDK 版本和 Android SDK 平台 android-19 上运行它。
我已经尝试了堆栈溢出中当前可用的几乎所有帖子，但似乎没有一个对我有用。我一直在尝试在静态库中存在的函数中设置断点，但没有成功。
有人可以提供有关我可能出错的地方以及如何从这里开始以使 ndk-gdb 调试工作的见解吗？
