无法在Android和NDK下使用gdb进行调试,启动Gdb会崩溃App

我在尝试使用Android NDK调试本机代码时遇到问题。

当应用程序正在运行时,我启动了ndk-gdb ,结果是gdb失去了与设备的连接,并且设备上的应用程序崩溃了。

设备(三星Galaxy 10.1)和模拟器都发生了同样的事情。 主机运行的是Mac OS X.应用程序的本机部分由多个.so库组成,使用ndk-build clean all NDK_DEBUG=1

我已经在下面附加了gdb输出。

任何帮助将不胜感激。

编辑:问题可能是’cp’命令失败? 空的“使用gdb setup init:”行?

我遇到了同样的问题。 原来问题是我在$ PROJECT_DIR / jni文件夹中执行ndk-gdb。 向上移动一个级别并从$ PROJECT_DIR执行修复了断开连接。
