如何使Valgrind调试程序通过一个程序 [英] How to make Valgrind debugger step through a program

问题描述

早上好，我试图使用Valgrind调试器来浏览一个程序。

我的valgrind命令行是 valgrind -tool memcheck --leak-check = full --db-enable = yes ./MatchUpAcurate.exe。我使用valgrind-3.5.0在Centos Linux版本5.5与gdb版本7,0.1-23.el5_5.2。

当valgrind询问附加到Debugger的问题时，我输入Yes。然后，valgrind调试器返回： 4428：return new tuple2< int，A>（2，i ++，p-> next（））;

当我尝试使用gdb步骤或继续命令，valgrind说

[New Thread 0x410fd10 LWP 6548]找不到LWP 6551的用户级线程：通用错误。

当我尝试使用 valgrind - valgrind命令行上的--single-step = yes 调试程序选项，valgriind说错误选项中止。

任何valgrind用户可以告诉我如何通过C ++源代码或继续通过程序？

解决方案

您还可以在3.7.0版本中获取vgdb。从发行说明：

• GDB服务器：Valgrind现在有这意味着
  可以控制从GDB的Valgrind运行，做所有通常的
  GDB可以做的事情（单步，断点，检查
  数据等）。还提供工具特定的功能。对于
  示例，当运行Memcheck时，可以从GDB中查询变量
  或内存的定义状态;支持任意大的
  内存观察点等。要使用GDB服务器，请使用标志--vgdb-error = 0启动
  Valgrind，然后按照屏幕上的
  指令操作。

Good morning, I am trying to use the Valgrind debugger to step through a program.

My valgrind command line is valgrind -tool memcheck --leak-check=full --db-enable=yes ./MatchUpAcurate.exe.

I am using valgrind-3.5.0 on Centos Linux release 5.5 with gdb version 7,0.1-23.el5_5.2.

I enter Yes when valgrind asks the question Attach to Debugger. Then, the valgrind debugger returns with: 4428: return new tuple2<int,A>(2, i++, p->next());

When I try to use the gdb step or continue command, valgrind says

[New Thread 0x410fd10 (LWP 6548] Cannot find user-level thread for LWP 6551: generic error.

When I try to use valgrind --single-step=yes debugger option on the valgrind command-line, valgriind says Bad option aborting.

Could any valgrind users show me how to step through C++ source code or continue through a program? Thank you.

解决方案

You can also get vgdb in the 3.7.0 release. From the release notes:

• GDB server: Valgrind now has an embedded GDB server. That means it is possible to control a Valgrind run from GDB, doing all the usual things that GDB can do (single stepping, breakpoints, examining data, etc). Tool-specific functionality is also available. For example, it is possible to query the definedness state of variables or memory from within GDB when running Memcheck; arbitrarily large memory watchpoints are supported, etc. To use the GDB server, start Valgrind with the flag --vgdb-error=0 and follow the on-screen instructions.

There's more info in the valgrind online manual.
