ROS下编译报错

创建answer功能包，里面有一个answer节点,编译报错

 

使用catkin_make命令进行编译，报错

 

解决方案：在answer功能包下的CMakeList.txt文件中添加

SET( CMAKE_CXX_FLAGS "-std=c++11 -O3")

则编译通过

 

参考：error This file requires compiler and library support for the ISO C++ 2011 standard.

 

error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

当使用CMAKE编译工程时，出现这个错误，解决办法：
在工程主目录的CMakeLists.txt中添加如下，可以编译成功：

SET( CMAKE_CXX_FLAGS "-std=c++11 -O3")
