Ubuntu 18 上的 ORB_SLAM3 安装错误

Question

我正在尝试在 Ubuntu 18 上安装 ORB_SLAM3...我还安装了所有先决条件，但是当我运行./build.sh时，我遇到了这个错误：

CMakeFiles/ORB_SLAM3.dir/build.make:62: recipe for target 'CMakeFiles/ORB_SLAM3.dir/src/System.cc.o' failed

在执行代码期间，还会显示此错误：

fatal error: Eigen/Core: No such file or directory
 #include <Eigen/Core>

谁能帮我一个忙，帮我解决这个问题？？

Answer 1

它已通过将#include<Eigen/Core>替换为include<eigen3/Eigen/Core>在包含此库的所有文件中解决。
或者
改为在终端中运行sudo cp -r /usr/include/eigen3/Eigen /usr/include 。
