错误消息:无法找到或打开PDB文件

Question

我尝试在NVIDIA的官方网站上运行示例程序.大多数程序运行顺利,除了少数我收到类似错误消息的地方.我该如何解决这个问题？这是运行名为"MatrixMul"的程序后得到的错误消息示例.

注意:我在Window7x64操作系统上安装了x32和x64 NVIDIA CUDA Toolkit v5.0.

PDB文件是Visual Studio特定文件,其中包含项目的调试符号.您可以忽略这些消息,除非您希望使用调试器进入这些dll的代码(这是可疑的,因为它们是系统dll).换句话说,你可以而且应该忽略它们,因为你不会有任何这些dll的PDB文件(至少默认情况下,你可以通过Microsoft Symbol Server调试时实际获得它们).所有这一切都意味着当你设置断点并踩过代码时,你将无法进入任何这些dll(你不想做任何事情).

为了完整起见,这是来自MSDN的官方PDB描述:

程序数据库(PDB)文件保存调试和项目状态信息,允许增量链接程序的Debug配置.使用/ ZI或/ Zi编译C/C++程序时,将创建PDB文件

同样为了将来参考,如果你想拥有自己代码的PDB文件,你将不得不使用/ ZI或/ Zi选项来构建你的项目(你可以通过项目属性设置它们 - > C/C++ - - >常规,然后设置"调试信息格式"字段.与您的情况无关,但我认为它可能在将来有用

Answer 2

使用VS 2013.尝试以下工具 - >选项 - >调试 - >输出窗口 - >模块加载消息 - >关闭它将禁用所加载模块的显示.

Answer 3

如果该消息困扰您,您需要运行具有管理权限的Visual Studio才能在Visual Studio上应用此方向.

工具 - >选项 - >调试 - >符号并选中复选框"Microsoft Symbol Servers",标记加载所有模块,然后单击加载所有符号.

Visual Studio将为您完成所有其他操作,您将在"输出"窗口的"调试"下显示此消息"Native"已退出,代码为0(0x0)"

1. 请检查Project Propeties> Configuration Properties> Linker> Debugging选项卡下的Generate Debug Info设置是否为Yes.如果没有,请尝试将其更改为是.

2. 那些特定的pdb(对于ntdll.dll,mscoree.dll,kernel32.dll等)是针对Windows API的,简单的应用程序不应该使用它们.但是,如果您找不到自己编译的项目的pdb,我建议确保项目属性>配置属性>调试>工作目录使用项目属性>配置属性>常规>输出目录中的值.

3. 您需要在"以管理员身份运行"模式下运行Visual c +.右键单击可执行文件,然后单击"以管理员身份运行"
