问题描述
I am performing calibration using link "https://github.com/lixiny/handeye-calibration-ros".
我正在使用链接“https://github.com/lixiny/handeye-calibration-ros”进行校准。
When I run catkin_make under src/ Handeye-Calibration-ROS , it is giving me following error:当我在src/ Handeye-Calibration-ROS下运行catkin_make时，它给了我以下错误：
/usr/include/pcl-1.10/pcl/common/impl/io.hpp:272:33: error: use of ‘auto’ in lambda parameter declaration only available with ‘-std=c++14’ or ‘-std=gnu++14’
and command catkin_make end with PCL error:和命令catkin_make以 PCL 错误结束：
make[2]: *** [camera_driver/CMakeFiles/realsense2_driver.dir/build.make:76: camera_driver/CMakeFiles/realsense2_driver.dir/src/realsense2_driver.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:2053: camera_driver/CMakeFiles/realsense2_driver.dir/all] Error 2
make: *** [Makefile:146: all] Error 2
Invoking "make -j24 -l24" failed
I tried CXXFLAGS=--std=gnu++14 , still same error.我试过CXXFLAGS=--std=gnu++14 ，仍然是同样的错误。

According to Cmake's site , you can set the c++ standard using:根据Cmake's site ，您可以使用以下方法设置 c++ 标准：
set_property(TARGET tgt PROPERTY CXX_STANDARD 14)
If you want to modify the makefile itself, adding the c++ flag should produce a command that looks similar to:如果您想修改 makefile 本身，添加 c++ 标志应该会生成一个类似于以下内容的命令：
g++ -std=c++14(or gnu++14) main.cpp -o main
