      cartographer安装步骤一般为

      cd cartographer
      mkdir build
      cd build
      cmake ..
      make  -j
      sudo make install
      

      执行cmake …时如果提示如下错误

      CMake Error at CMakeLists.txt:32 (find_package):By not providing "FindEigen3.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Eigen3", but CMake did not find one.
      Could not find a package configuration file provided by "Eigen3" with any of the following names:
          Eigen3Config.cmake
          eigen3-config.cmake
      

      如果系统确实已经安装过Eigen3 (sudo apt-get install libeigen3-dev),请点击下载本文件 ,然后放入cartographer源码目录下的cmake文件夹内的modules内,例如/home/xiaoqiang/Documents/cartographer/cmake/modules
      现在再次执行cmake … 问题应该已解决
