Hi , I am trying to use the following code , and I am getting the error :
LED2_pub:7: error: cannot declare variable ‘easyvr_msg’ to be of abstract type ‘rosserial_arduino::easyvr’
/home/sp/arduino-1.0.1/libraries/ros_lib/rosserial_arduino/easyvr.h:13: note: because the following virtual functions are pure within ‘rosserial_arduino::easyvr’:
/home/sp/arduino-1.0.1/libraries/ros_lib/ros/msg.h:44: note: virtual int ros::Msg::serialize(unsigned char*) const
/home/sp/arduino-1.0.1/libraries/ros_lib/ros/msg.h:47: note: virtual const char* ros::Msg::getMD5()
The code I am trying to use is :
#include
#include
#include
#include
#include
ros::NodeHandle nh;
rosserial_arduino::easyvr easyvr_msg;
ros::Publisher pub_easyvr("easyvr" ,&easyvr_msg);
EasyVR easyvr();
void setup()
{
Serial.begin(57600);
Serial.print("Starting...\n");
nh.initNode();
nh.advertise(pub_easyvr);
}
void loop()
{
pub_easyvr.publish(&easyvr_msg);
nh.spinOnce();
delay(1000);
}
Can anyone try to explain to me what I am doing wrong? i have made easyvr msg file and put the easyvr.h under rosserial_arduino too. Thanks in advance.
Regards,
Steve
