问题一:在创建工作空间时,在运行$catkin_make后出现:
CMake Error at/opt/ros/indigo/share/catkin/cmake/safe_execute_process.cmake:11 (message):

解决办法:
卸载ros:
http://blog.csdn.net/yeluohanchan/article/details/75578268
重新安装:
http://wiki.ros.org/cn/indigo/Installation/Ubuntu
重新建立工作目录:
http://wiki.ros.org/cn/ROS/Tutorials/InstallingandConfiguringROSEnvironment
mkdir -p ~/[工作目录路径][如/dev/catkin_ws/src]
cd ~/dev/catkin_ws/src[到新建的目录下]
catkin_init_workspace
新建端口
source ~/dev/catkin_ws/devel/setup.bash
echo "source ~/dev/catkin_ws/devel/setup.bash">> ~/.bashrc
cd ~/dev/catkin_ws[到工作空间文件夹]
catkin_make
若显示:
-- +++ processing catkin package:'chapter2_tutorials'
-- ==>add_subdirectory(chapter2_tutorials)
-- Configuring done
-- Generating done
-- Build files have been written to:/home/cookie/dev/catkin_ws/build
####
#### Running command: "make -j8-l8" in "/home/cookie/dev/catkin_ws/build"
####
cookie@cookie909:~/dev/catkin_ws$ sourcedevel/setup.bash
则说明编译完成
检查:新端口下
cat ~/.bashrc
显示
source /opt/ros/indigo/setup.bash
source ~/catkin_ws/devel/setup.bash
source ~/dev/catkin_ws/devel/setup.bash
成功添加环境变量
问题二:运行roslaunch时出现
[start_demo.launch] is neither a launchfile in package [learning_tf] nor is [learning_tf] a launch file name
The traceback for the exception was writtento the log file
解决办法:
在之前将devel文件至于当前环境变量中,即
$cd ~/catkin_ws
$source devel/setup.bash
问题三:
$rosrunxacro xacro.py `rospack /robots/pr2.urdf.xacro > pr2.urdf
出现
rospkg.common.ResourceNotFound:pr2_description
ROS path [0]=/opt/ros/indigo/share/ros
ROS path [1]=/home/cookie/catkin_ws/src
ROS path [2]=/opt/ros/indigo/share
ROS path [3]=/opt/ros/indigo/stacks
解决:此xacro不在ROS_PACKAGE_PATH路径中可看到

问题四:在运行catkin_make,后出现:
you either need to install the package withthe same name or change your environment so that it can be found.\
Could not find a package configuration fileprovided by "convex_decomposition" with any of the following names:
Add the installation prefix of"convex_decomposition" to CMAKE_PREFIX_PATH or set"convex_decomposition_DIR" to a directory containing one of the abovefiles. If"convex_decomposition" provides a separate development package or SDK, be sure it has beeninstalled.
Specifies a path which will be used by theFIND_XXX() commands. It contains the “base” directories, the FIND_XXX()commands append appropriate subdirectories to the base directories. SoFIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY()appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append/include . By default it is empty, it is intended to be set by the project. Seealso CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH,CMAKE_PROGRAM_PATH.\
解析:无法找到具有以下任何名称的“convex_decomposition”提供的程序包配置文件：
可能原因:不小心删除了urdf_tutoorial 下的launch文件,导致某型包无法调用,也可能是使用了rosdep安装了包,查阅网上有以下说法:
不要使用rosdep来安装你感兴趣的包。这不是它的目的。它只处理依赖关系。
解决办法:安装对应的包
$sudo apt-get installros-indigo-convex-decomposition
后显示缺少ivcon包,
$sudo apt-get install ros-indigo-ivcon
显示编译成功,
问题五:
在catkin_ws下编译
$catkin_make
显示:Linking CXX executable /home/cookie/catkin_ws/devel/lib/beginner_tutorials/talker
Linking CXX executable/home/cookie/catkin_ws/devel/lib/beginner_tutorials/listener
Linking CXX executable/home/cookie/catkin_ws/devel/lib/testbot_description/parser
解决办法:
在编译前运行:
$source devel/setup.bash
解决问题
问题六.
运行control.launch时出现
[ WARN] [1521073681.464035103]: The rootlink base_stander has an inertia specified in the URDF, but KDL does notsupport a root link with an inertia. Asa workaround, you can add an extra dummy link to your URDF.
