错误消息：找不到或打开PDB文件 [英] Error Message : Cannot find or open the PDB file

问题描述

我试过运行 NVIDIA官方网站提供的示例程序。大多数程序运行顺利，除非在那里我得到类似的错误消息。如何解决这个问题？这里有一个错误信息的例子，我得到了运行一个名为MatrixMul的程序。

I tried running sample programs provided at NVIDIA's official site. Most of the programs ran smoothly except few where I get similar error messages. How can I fix that? Here's a sample of error message I got after running a program named "MatrixMul".

注意：我已安装了x32和x64 NVIDIA CUDA工具包 v5.0在我的Window7x64操作系统上。

Note: I have installed both x32 and x64 NVIDIA CUDA Toolkit v5.0 on my Window7x64 OS.

推荐答案

PDB文件是一个Visual Studio特定的文件，其中包含项目的调试符号。你可以忽略这些消息，除非你希望用调试器（这是可疑的，因为那些是系统DLL）步入到这些DLL的代码。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，你实际上可以通过 Microsoft符号服务器）。所有这意味着，当你设置一个断点并通过代码，你将无法进入任何这些DLL（你不会想要做的）。

The PDB file is a Visual Studio specific file that has the debugging symbols for your project. You can ignore those messages, unless you're hoping to step into the code for those dlls with the debugger (which is doubtful, as those are system dlls). In other words, you can and should ignore them, as you won't have the PDB files for any of those dlls (by default at least, it turns out you can actually obtain them when debugging via the Microsoft Symbol Server). All it means is that when you set a breakpoint and are stepping through the code, you won't be able to step into any of those dlls (which you wouldn't want to do anyways).

为了完整性，这里是MSDN的官方PDB描述：

Just for completeness, here's the official PDB description from MSDN:

程序数据库（PDB）文件保存调试和项目状态信息，允许对程序的Debug配置进行增量链接。在使用/ ZI或/ Zi编译C / C ++程序时创建PDB文件

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

要有自己的代码的PDB文件，您将必须构建您的项目与/ ZI或/ Zi选项启用（您可以通过项目属性设置 - > C / C ++ - >常规，然后设置字段调试信息格式）。与您的情况不相关，但我认为这可能会在将来有用

Also for future reference, if you want to have PDB files for your own code, you would would have to build your project with either the /ZI or /Zi options enabled (you can set them via project properties --> C/C++ --> General, then set the field for "Debug Information Format"). Not relevant to your situation, but I figured it might be useful in the future
