Error: stack/package exemplo1 not found

Como posso resover isso???

executo um pacote e dá not found...

Olá! Eu compilo este programa, mas quando vou executa-lo aparece essa msg Error: stack/package exemplo1 not found alguém pode me ajudar...

Segue abaixo o codigo CPP, mais o package.xml e o CMakeList.txt

exemplo1.cpp

// This program published randomly-generated velocity // messages for turtlesim. #include <ros ros.h=""> #include <turtlesim velocity.h=""> // For turtlesim::Velocity #include <stdlib.h> // For rand() and RAND_MAX

int main(int argc, char **argv) { // Initialize the ROS system and become a node. ros::init(argc, argv, "publish_velocity"); ros::NodeHandle nh;

// Create a publisher object. ros::Publisher pub = nh.advertise<turtlesim::velocity>( "turtle1/command_velocity", 1000);

// Seed the random number generator. srand(time(0));

// Loop at 2Hz until the node is shut down. ros::Rate rate(2); while(ros::ok()) { // Create and fill in the message. turtlesim::Velocity msg; msg.linear = float(rand())/float(RAND_MAX); msg.angular = 2*float(rand())/float(RAND_MAX) - 1;

// Publish the message.
pub.publish(msg);

// Send a message to rosout with the details.
ROS_INFO_STREAM("Sending random velocity command:"
  << " linear=" << msg.linear
  << " angular=" << msg.angular);

// Wait until it's time for another iteration.
rate.sleep();

} }
