opencv2.4.4 visual studio 2012 无法找到或打开 PDB 文件

Question

我正在使用 opencv 库和 VS2012 运行一个程序。我使用的是 windows 7 64 位，所以我通过项目属性将配置管理器更改为 x64。在我系统的环境变量中，我首先从命令提示符输入了这些条目:setx -m OPENCV_DIR C:\OpenCV\build 并将其添加到系统路径:%OPENCV_DIR%\build\x64\vc11\bin

在 Visual Studio 的属性管理器中，我将以下文件夹链接添加到项目属性:

1. 在C/C++下，附加include目录，我添加了:$(OPENCV_DIR)\include

2. 在 Linker 下，Additional Library Directory，我添加了； $(OPENCV_DIR)\x64\vc10\lib;

3. 链接器、输入、附加依赖项，我添加了以下内容:

   opencv_core244d.lib opencv_imgproc244d.lib opencv_highgui244d.lib opencv_ml244d.lib opencv_video244d.lib opencv_features2d244d.lib opencv_calib3d244d.lib opencv_objdetect244d.lib opencv_contrib244d.lib opencv_legacy244d.lib opencv_flann244d.lib opencv_gpu244d.lib opencv_nonfree244d.lib opencv_photo244d.lib opencv_stitching244d. lib opencv_ts244d.lib opencv_videostab244d.lib

当我运行我的程序时，我遇到了这个错误

有人知道为什么会这样吗？

Answer 1

这些都不是 fatal error 消息。这些只是诊断陈述(例如，没有任何问题，它只是通知您某些事件)。

PDB 文件是特定于 Visual Studio 的文件，其中包含项目的调试符号。如果您使用的是 OpenCV 的预构建库/dll，则不会有任何这些文件。幸运的是，您可以忽略这些消息，除非您希望使用调试器单步执行这些 dll 的代码。

如果它足够困扰您，您可以从源代码重新构建 opencv 并启用 /ZI 或 /Zi 选项。然而，就目前而言，这些消息都不会表明有任何问题。您的程序以代码 1 (0x1) 退出是由其他原因引起的，但您没有提供足够的信息来确定是什么原因。

Here's the official description of PDB files from MSDN:

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
