安装goolge cartographer提示无法找到Eigen3的解决办法之一



  • 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
