visual-studio-2010 - 错误消息: Cannot find or open the PDB file

Question

我尝试运行 NVIDIA's official site 提供的示例程序。大多数程序都运行顺利，除了少数程序我收到类似的错误消息。我该如何解决这个问题？这是运行名为“MatrixMul”的程序后收到的错误消息示例。

注意:我已经安装了 x32 和 x64 NVIDIA CUDA Toolkit v5.0 在我的 Window7x64 操作系统上。

PDB 文件是 Visual Studio 特定的文件，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(这是值得怀疑的，因为这些是系统 dll)。换句话说，您可以而且应该忽略它们，因为您不会拥有任何这些 dll 的 PDB 文件(至少默认情况下，事实证明您可以在通过 Microsoft Symbol Server 进行调试时实际获取它们)。这意味着当您设置断点并单步执行代码时，您将无法单步执行任何这些 dll(无论如何您都不想这样做)。

为了完整起见，以下是来自 MSDN 的官方 PDB 描述:

A program database (PDB) file holds debugging and project state information that allows incremental linking of a Debug configuration of your program. A PDB file is created when you compile a C/C++ program with /ZI or /Zi

另外，为了供将来引用，如果您想要为自己的代码创建 PDB 文件，则必须在启用/ZI 或/Zi 选项的情况下构建项目(您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，但我认为它将来可能有用
