问题描述
这是我运行后 NDK-GDB据很多教程,当它链接到你
(GDB)
$ C得到$ C>服务器,您需要输入继续
但什么之后如何到那里后,调试code。在我的情况下,它会显示继续
,并保持这个样子。我有什么做进一步的我完全无能。
This is what I am getting after running ndk-gdb
according to many tutorials when it links to you to (gdb)
server you have to type continue
but what after that how to debug the code there after. In my case it displays Continuing
and remain like this. WHat i have to do further I am totally clueless.

warning: Breakpoint address adjusted from 0x40005a53 to 0x40005a52.
(gdb) continue
Continuing.
如何调试?
按照 NDK-文档
You can set breakpoints with 'b <location>' and resume execution with 'c'
(for 'continue'). See the GDB manual for a list of commands.
如何做到这一点。
How to make this happen.
推荐答案
的命令是一样的gdb。一个基本的底漆:
The commands are the same as in gdb. A basic primer:
- 输入设置断点
B&lt;作用名称&gt;
或B&LT;文件&gt;:&LT;行号&GT;
- 步入功能通过键入
取值
- 转到下一行键入
N
- 继续
执行ç
- 打印变量或前pression值为
打印&LT;&EXP GT;
- 只需按下回车键 重复上一次输入的命令
- Set a breakpoint by entering
b <function name>
orb <file>:<line number>
- step into functions by typing
s
- go to next line by typing
n
- continue execution with
c
- print a variable or expression value with
print <exp>
- repeat the last typed command by just hitting enter
您可以找到更多的COM prehensive gdb的在线教程。我个人有一个GDB的cheatsheet打印出来,并贴在墙上。这应该足以让你开始。
You can find much more comprehensive gdb tutorials online. I personally have a gdb cheatsheet printed out and posted on my wall. This should be enough to get you started.
