ROS 相关问题记录

1、卸载ROS

sudo apt-get remove -f ros-<distro>-desktop-full
sudo apt-get remove -f ros-<distro>-*
sudo rm -r /opt/ros/<distro>/

2、<AAA>_msgs can't be found

错误：

CMake Error at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "<AAA>_msgs" with
  any of the following names:

    <AAA>_msgsConfig.cmake
    <AAA>_msgs-config.cmake

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

原因：可能是版本问题

解决：1）修改cmakelist

                    将find_package中<AAA>_msgs 改为 message_generation

                    将catkin_package中<AAA>_msgs 改为 message_runtime        

           2 )对应修改.xml

           3 )将使用到<AAA>_msgs 的头文件或源文件中的<AAA>_msgs改为该包/工程名（project name）
