Question

您好我正在尝试使用自制软件在我的MAC上安装ROS。虽然我收到了此消息：

 CMake Error at CMakeLists.txt:7 (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
Add the installation prefix of "Eigen3" to CMAKE_PREFIX_PATH or set
"Eigen3_DIR" to a directory containing one of the above files.  If "Eigen3"
provides a separate development package or SDK, be sure it has been
installed.
-- Configuring incomplete, errors occurred!

我是ROS的初学者，所以有人可以帮我解决这个问题。我已检查是否安装了Eigen，已安装版本3.2.4

Answer 1

This为我解决了这个问题。

这似乎已经解决了，但我会分享我是如何得到这个的   工作：在ros build工作区的其他地方，我找到了一份副本   FindEigen3.cmake：

ros_catkin_ws $ cp   SRC / orocos_kinematics_dynamics / orocos_kdl /配置/ FindEigen3.cmake
  src / perception_pcl / pcl_ros / cfg /然后我删除了以下内容   CMakeLists：

find_package（需要特征3）用来自的这些行替换它   orocos CMakeLists

find_package（Eigen 3 QUIET）if（NOT Eigen_FOUND）
  包括：（$ {} PROJ_SOURCE_DIR /cfg/FindEigen3.cmake）
  set（Eigen_INCLUDE_DIR $ {EIGEN3_INCLUDE_DIR}）endif（）   include_directories（$ {Eigen_INCLUDE_DIR}）说实话，我   没有改变配置 - ＆gt; cfg当我做我的构建，但似乎有   工作

Answer 2

我为解决这个问题所做的是：

使用.cmake文件中的消息（警告$ {CMAKE_ROOT}）将其打印出来，查找CMAKE_ROOT的当前值
确保该文件夹中存在Modules / FindEigen3.cmake
如果没有，请从https://github.com/RainerKuemmerle/g2o/blob/master/cmake_modules/FindEigen3.cmake
