Do you guys have any experience to share about debugging large macros? I am
using sunstudio. It definitely can not give a direct location where I am
inside the Macro. My current solution is to understand the complex macro
completely and set breakpoint at possible places. Do you guys have any
better solution? I heard that in VisualStudio people can locate in the
preprocessed file. Is that true. Thanks

发帖数: 3195 | 10 要改 mysql 内部的一个模块 (storage engine).
程序写得差不多了, 发现debug起来真麻烦.
编译完 server后, 安装, 启动, 然后启动 client 运行SQL 语句, 然后查看server
log,
server 杀起来也很麻烦, 还得另开一窗口敲 kill -9. 然后改程序, 再重复.
以前很少搞这种 server/client 结构的调试, 不知道有没有简洁一点的调试方法??? |

We develop a SW, after install and reboot.
The 1st time it runs the app, there's a "just-in-time" error.
So hook it to the VS 2005, from the stack i can see our app calls "new",
it calls malloc/heap etc.
Now if i reboot the pc, retry all these, everything is ok now.
Our app has that "user access control" thing, if turn o... 阅读全帖 |

发帖数: 1160 | 18 no I don't have any reason. The project has been like this when I took over
it.
I have no idea what to do with msvcrt.lib, libcmt.lib, msvcrtd.lib. What is
the common practice about them, in debug/release mode?
I am lack of this kind of knowledge. I only focus on the programming stuff,
never look into compilation/link thing.
Thanks. |

发帖数: 1160 | 19 summary:
When the previous programmer added the external lib, he might get a wrong
one, maybe add an dynamic one for static link, or maybe that lib was buggy,
then the project is not working.
So the programmer added the /NODEFAULTLIB to get it working in Debug mode.
He wasn't able to make it work in Release mode, and he decided to leave it
like that, thinking that is the best interest for this project. Fxxk u!
With the correct lib of new version, and the help from thrust, it is working
well now. |

这是什么原因？ |

d**********x
发帖数: 4083 | 27 1. 打断点怎么会打不进去。。。你肯定是弄错了
2. 打log的方式适合调试和UI有关的bug，一般的bug还是断点比较好
3. 如果单步了半天没有头绪，不妨跳出来用脑子分析下问题，想想debug策略
4. 十几个函数真不算多
5. gdb可以存profile的，你google一下，省得每次开gdb还要把断点重新打一遍。

发帖数: 1212 | 33 脚本编程没有比较大的问题，赵策兄你有比较大的问题，需要好好学习脚本编程
个人觉得，靠DEBUG来找错本身就是很低效率的行为
有本书叫做interactive programming，好好看看吧。interactive programming是人月
神话中宣称的70年代编程领域效率提高的两种主要方法之一
我写脚本的时候，写一行测一行写一个函数测一个函数，所以一路写下来，程序都是对
的。怎么测？用REPL。如果有emacs，C-c C-c就测试了。测完了像整个unit test就整
，不想就扔了算了
写程序的时候就保持一个使得程序容易测试的念头：比如，在逻辑上分块，写容易测试
修改的小函数，使用函数式风格，都是办法 |

发帖数: 54598 | 34 我用vi搞JAVA没有什么问题
基本上可以无bug
但是你要说让我去看别人写的代码
要很快debug出来，这个我自信水平达不到
我也不相信这里有谁能做到
毕竟人不是机器
我对错误的容忍度比较高，很少装，该用啥就用啥
不过分依赖人本身，因为人总归是人，犯错是常事
我大学老师，上黑板做四则运算都能算错
更何况是写点代码了 |
