Question

I am interested to load contents of rosbag into databse using sqlite and c++.
while including rosbag/view.h and rosbag/bag.h header file in my cpp file in visual studio code I am facing error of no such file or directory
code: ref http://wiki.ros.org/rosbag/Cookbook#C.2B-.2B-
#include <ros/ros.h>
#include <rosbag/bag.h>
#include <rosbag/view.h>
int main(int argc, char **argv)
{
rosbag::Bag bag;
bag.open("input.bag", rosbag::bagmode::Read);
rosbag::View view(bag);
ros::Time bag_begin_time = view.getBeginTime();
ros::Time bag_end_time = view.getEndTime();
std::cout << "ROS bag time: " << (bag_end_time-
bag_begin_time).toSec() << "(s)" << std::endl;
bag.close();
return 0;
}
error:

Answer 1

Issue is resolved by including ros package, directories and libraries in the CmakeLists.txt and executing the code with cmake and make respectively now able to see the rosbag duration.
cmake_minimum_required(VERSION 3.13 FATAL_ERROR)
project(esw2 VERSION 0.0.1 LANGUAGES CXX)
find_package(rosbag REQUIRED)
add_executable(folder_name
file.cpp
)
target_include_directories(bag_reader
PUBLIC
include
${rosbag_INCLUDE_DIRS}
)
target_link_libraries(bag_reader
PRIVATE
${rosbag_LIBRARIES}
stdc++fs
)
