您好，在编译teaser++过程中报错如上，请问如何解决呀

我在Ubuntu18.04上没有遇到过这个问题，你或许可以参考NeBula-Autonomy/LAMP#20.

谢谢您，问题已经解决。但是今天在我编译你的代码的时候又报错如下opencv问题,请问opencv版本需要4.0吗，我现在是3版本，但是原版lvi-sam我可以运行成功。
CMake Error at LVI-SAM-modified/CMakeLists.txt:43 (find_package):

刚刚这个问题我已经解决，把cmakelists文件中的opnecv改成了3版本，编译成功了。但是我运行ros launch lvi_sam run.launch文件报错如下：[lvi_sam_mapOptmization-8] process has died [pid 13543, exit code 127, cmd /home/zyp/LVI_plus01/devel/lib/lvi_sam/lvi_sam_mapOptmization __name:=lvi_sam_mapOptmization __log:=/home/zyp/.ros/log/7eca333a-e654-11ee-9dcf-6c24085b729f/lvi_sam_mapOptmization-8.log].

你可以将[https://github.com/NudtCalculus/LVI-SAM-modified/blob/dd6fe966206ec733c51e8f9b1b9db5e88f42632d/CMakeLists.txt#L13] 修改为"RelWithDebInfo“或者"Debug"进行调试，寻找报错的代码段。如果你使用的是Ubuntu20.04，可以参考 [https://github.com/NeSC-IV/LVI-SAM-Easyused] 。如果使用OpenCV4编译需要将所有#include <opencv/cv.h>更改为<opencv2/opencv.hpp>( [https://github.com/NeSC-IV/LVI-SAM-Easyused] )，同时需要编译与OpenCV4适配的cv_bridge，否则cv::FileStorage会出错。
