这个错误的原因是代码中使用了 C++11 的特性，但是编译时没有开启 C++11 标准。你需要在编译时加上选项 -std=c++11 或者 -std=gnu++11 来开启 C++11 标准。

具体来说，在你的 CMakeLists.txt 文件中添加以下行：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

这将会把 C++11 标准的编译选项加入到编译命令中，从而解决这个问题。

另外，还有一个错误是 'goal' does not name a type，这可能是因为你没有在代码中定义 goal 变量的类型。你需要检查一下代码中是否有定义 goal 变量的类型，并且确保它在使用之前已经被定义。

ubuntu16.04ros编译时报错CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by "robot_audio" with any of the following names: robot_audioConfig.cmake robot_audio-config.cmake Add the installation prefix of "robot_audio" to CMAKE_PREFIX_PATH or set "robot_audio_DIR" to a directory containing one of the above files. If "robot_audio" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): bobac3_audio/CMakeLists.txt:10 (find_package) -- Configuring incomplete, errors occurred! See also "/home/oy/ros_workspace/build/CMakeFiles/CMakeOutput.log".

这个报错是因为在编译 bobac3_audio 时，需要依赖 robot_audio 这个包，但是系统找不到这个包。你可以尝试以下几个方法：

1. 确认你已经安装了 robot_audio 包。如果没有安装，可以使用以下命令安装：

   sudo apt-get install ros-kinetic-robot-audio

2. 确认你的 CMAKE_PREFIX_PATH 环境变量是否包含了 robot_audio 包的安装路径。可以使用以下命令查看：

   echo $CMAKE_PREFIX_PATH

如果没有包含 robot_audio 包的安装路径，可以使用以下命令设置：

   export CMAKE_PREFIX_PATH=$CMAKE_PREFIX_PATH:/opt/ros/kinetic/share/robot_audio

注意，这里的安装路径可能与你的实际安装路径不同，需要根据实际情况进行修改。

3. 如果以上两种方法都不行，可以尝试在 CMakeLists.txt 中手动指定 robot_audio 包的路径，例如：

   find_package(robot_audio REQUIRED PATHS /opt/ros/kinetic/share/robot_audio/cmake)

这里的路径也需要根据实际情况进行修改。

这个错误可能是因为在运行CMake时，找不到名为"bobac2_description_node"的目标。这可能是因为在CMakeLists.txt文件中没有正确地定义目标或源文件。您可以检查一下CMakeLists.txt文件中的目标和源文件是否正确定义。另外，您可以尝试清理并重新构建项目，以确保没有编译错误。您也可以查看CMakeError.log和CMakeOutput.log文件，以获取更多关于错误的详细信息。
