#include "ros/ros.h"
#include "std_msgs/String.h"
#include <sstream>
#include "socketcan_interface/socketcan.h"
#include "socketcan_interface/threading.h"
#include "socketcan_interface/string.h"

void handleFrames(const can::Frame &f){
    // handle all frames
    LOG(can::tostring(f, true)); // lowercase: true
}
void handleFrame123(const can::Frame &f){
    // handle specific frame
    LOG("123? " << can::tostring(f, true)); // lowercase: true
}

int main(int argc, char **argv)
{
    can::ThreadedSocketCANInterface driver;
    if(!driver.init("can0", false)) return 1; // read own messages: false

    can::CommInterface::FrameListener::Ptr all_frames = driver.createMsgListener(handleFrames);
    can::CommInterface::FrameListener::Ptr one_frame = driver.createMsgListener(can::MsgHeader(0xFF32), handleFrame123); // handle only frames with CAN-ID 0x123

    ros::init(argc, argv, "data_raw");
    ros::NodeHandle n;
    ros::Publisher canbus_pub = n.advertise<std_msgs::String>("canbus", 1000);

    while (ros::ok())
    {
      std_msgs::String msg;
      std::stringstream ss;

      ss << all_frames;
      msg.data = ss.str();
      canbus_pub.publish(msg);

      //ROS_INFO("%s", msg.data.c_str());

      //ROS_INFO("%s", std::cout<<"all_frames is of type: "<<typeid(all_frames).name()<<std::endl);

      ros::spinOnce();
    }

  driver.shutdown();
  return 0;
}

This is the code i reffered

This kind of issue is often an issue with build rules; particularly if you're using a library that's not installed by default. Please edit your question to include your build rules (CMakeLists.txt) and the exact error message.

I'm not sure if you still need help with this but normally you would have to install the socketcan_interface package on your computer. You can do this by typing:

sudo apt-get install ros-[your_distribution]-socketcan-interface

So in my case, I would type:

sudo apt-get install ros-indigo-socketcan-interface

Then you should be able to use the code above.
