2018-08-08 01:42:42 -0500 | marked best answer | How to publish messages on a topic of type rosgraph_msgs/Clock? Hello! I want to give values to a topic with this type of mesage (rosgraph_msgs/Clock) I create a variable called "reloj" for example: rosgraph_msgs::Clock reloj; How do I give a value to that variable?, because it has two parts (secs and nsecs) For example in float64 I give it the value this way std_msgs::Float64 variable; variable.data = 0; I would like to do the same but in rosgraph_msgs/Clock, one value for "secs" and one for "nsecs" I tried: reloj.clock.secs = 1; reloj.clock.nsecs = 100; reloj.clock_secs = 1; reloj.clock_nsecs = 100; But this does not work I found that putting the following does work reloj.clock = {5,88}; but when creating the node executable, I get this warning: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 reloj.clock = {5,88}; I use ROS kinetic and roscpp (c++) this is the code in c++ thank you very much |
