从给出的错误信息来看，问题似乎是在链接过程中找不到 cv::xfeatures2d::VGG::getDefaultName 这个符号的定义。这通常意味着在编译时没有正确地包含或链接了相关的源文件或库。以下是一些可能的解决步骤：

1. 确认源文件编译：确保包含 cv::xfeatures2d::VGG::getDefaultName 定义的源文件被正确编译并生成了对象文件。这可能涉及到检查你的构建系统是否包括了正确的源文件。
2. 确认库链接：确保你在链接过程中包含了所有必要的库。对于OpenCV，通常会有一些库是专门为某些功能或模块提供的，例如xfeatures2d模块。确保你在链接过程中包含了所有必要的库。
3. 确认配置：检查你的项目配置，确保你使用的是正确的编译器标志和设置。有时候，配置问题可能会导致链接错误。
4. 检查OpenCV版本和安装：确认你安装的OpenCV版本是否包含了你需要的模块和功能。有时候，某些功能可能在新版本中被移除或更改。

由于没有具体的代码和配置细节，这些步骤可能需要根据你的具体情况进行调整。如果你使用的是特定的构建系统或IDE，你可能需要查看该系统的文档或寻求具体的帮助。

此外，对于你的项目配置和代码，如果能提供更多的信息（如构建系统、IDE、相关代码片段等），我可能能提供更具体的帮助。
