Question

我正在尝试将每个系统与ros合并，但在此之前我想检查它是否运行良好，以便我在CLion上运行文件，我收到了这些错误。

当我第一次编译它时，它很好，但后来我遇到了mrpt头文件的一些问题，我将它们全部删除并手动编译，这个问题就发生了。我能得到一些建议吗？

您的系统中可能安装了不同的MRPT版本。

除非你有充分理由这样做，否则我不建议你做sudo make install;只需在自己的构建目录中编译项目，就会生成一个MRPTConfig.cmake文件，允许CMake从ROS或其他任何用户项目中找到MRPT。

如果CMake没有自动找到它，只需设置环境变量export MRPT_DIR=/home/xxx/path/to/mrpt/build即可。

你现在的问题是清除/usr/local/下可能存在的所有混乱。看看那个目录，如果make install编辑的唯一项目是MRPT，我强烈建议您使用sudo rm -fr /usr/local/*删除它。

如果你有其他项目......那么......你必须从MRPT构建目录运行sudo make uninstall，然后手动确保没有剩余的文件。

针对OpenCV的链接错误也看起来像CMake为一个opencv版本配置了项目，然后安装了另一个（可能是通过ROS包？）。在完成上述/usr/local的清理后，删除当前的MRPT CMake构建目录并从头开始。

在我手动编译mrpt之后，我遇到了构建mrpt文件的问题
