c++ - Catkin构建中的错误找不到软件包 “numpy_eigen”

Question

最初的评论引导我通过，直到出现以下错误
运行sudo apt install libeigen3-dev后出现新错误

    CMake Error at rpg_emvs/mapper_emvs/CMakeLists.txt:16 (find_package):
  By not providing "FindEigen.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Eigen", but
  CMake did not find one.

  Could not find a package configuration file provided by "Eigen" with any of
  the following names:

EigenConfig.cmake
eigen-config.cmake

  Add the installation prefix of "Eigen" to CMAKE_PREFIX_PATH or set
  "Eigen_DIR" to a directory containing one of the above files.  If "Eigen"
  provides a separate development package or SDK, be sure it has been
  installed.

这是Cmakelists.txt文件

project(mapper_emvs)
cmake_minimum_required(VERSION 2.8.3)

find_package(catkin_simple REQUIRED)
catkin_simple(ALL_DEPS_REQUIRED)

find_package(Eigen REQUIRED)
find_package(Boost REQUIRED system filesystem date_time thread)
#Setting include, lib directories and definitions 
include_directories(${${Boost_INCLUDE_DIR} ${EIGEN_INCLUDE_DIRS}})

我应该尝试评论本征添加包部分吗？
更新CMAKE文件后出现新错误

/home/ubuntu/emvs_ws/src/numpy_eigen/include/numpy_eigen/boost_python_headers.hpp:23:22: fatal error: Eigen/Core: No such file or directory
compilation terminated.

仅构建numpy_eigen后发生错误

Answer 1

您可以下载并保存在/home/ubuntu/emvs_ws/src(假设这是您的ros工作区)文件夹中，并与需要numpy_eigen的其他软件包一起编译。

cd /home/ubuntu/emvs_ws/src
git clone https://github.com/ethz-asl/numpy_eigen.git
cd ../
catkin_make 

我猜最好用catkin_make代替catkin build，因为那些软件包在catkin build中会出现奇怪的错误。另外，如果此程序包依赖于catkin_simple，则如果您没有catkin_simple，则将该存储库克隆到src中，然后尝试执行catkin_make。
