答案对人有帮助，有参考价值 0 根据您提供的错误信息，问题出现在链接阶段，具体错误为未定义引用（undefined reference）。这通常意味着您的项目在编译时没有找到所需的库函数。以下是一些可能的原因和解决方案： 1. 缺少库文件：确保您已经正确安装了所需的库文件，并且在编译时包含了它们的路径。在这种情况下，您需要确保飞卡（FlyCapture）库已正确安装，并且库文件路径已添加到编译器的搜索路径中。 2. 库文件版本不兼容：检查您的项目是否使用了与库文件兼容的版本。如果版本不兼容，您可能需要更新库文件或修改项目以使用兼容的版本。 3. 链接器设置不正确：检查您的项目设置，确保链接器正确设置了库文件的路径。您可能需要在编译器的链接器设置中添加库文件的路径。 4. 缺少依赖库：检查您的项目是否缺少其他依赖库。在这种情况下，您可能需要安装或链接其他库文件。 5. 编译器或链接器错误：在某些情况下，编译器或链接器可能存在错误。您可以尝试更新编译器或链接器到最新版本，或者在不同的编译器或链接器上重新编译项目。为了解决这个问题，您可以尝试以下步骤： 1. 确保飞卡（FlyCapture）库已正确安装，并且库文件路径已添加到编译器的搜索路径中。 2. 检查您的项目设置，确保链接器正确设置了库文件的路径。 3. 如果问题仍然存在，请尝试更新库文件或修改项目以使用兼容的版本。 4. 如果您仍然遇到问题，请考虑在不同的编译器或链接器上重新编译项目。
