我试图调试一个调用本地代码来执行一些GL渲染的android应用程序。本机代码是我试图移植的现有代码(并且我不太清楚)。我已经有了正确编译，链接和正确安装的代码，并且我有一些原生函数调用了从我的Java代码正确调用的代码。我收到了一个段错误，我试图追踪，并且遇到了一些问题，让gdb在程序中设置断点。这是与Cygwin的Windows XP - 我应该提到我还在学习gdb。gdb输入/输出错误远程调试到Android

在模拟器中启动应用程序。

在命令提示符：

> adb forward tcp:1234 tcp:1234

> adb shell

# gdbserver localhost:1234 --attach 2120

gdbserver localhost:1234 --attach 2120

Attached; pid = 2120

Listening on port 1234

在cygwin外壳：

arm-eabi-4.2.1/bin/arm-eabi-gdb.exe out/apps/app-android/libDM.so

所以它看起来像断点被设定好了，并且这些符号都OK，但也许地址是当它试图插入断点时错误。我已经尝试过上面引用的网页中的几个不同命令的变体，但到目前为止，没有运气。

任何想法发生了什么？
