In my file I have included #include "ros/ros.h" it says no such file or directory. I am using VS Code, ROS noetic on Ubuntu 20.04 LTS.
Here is my package.xml:

</package>
Here is my CMakeLists.txt
cmake_minimum_required(VERSION 3.0.2)
project(beginner_tutorials)
Compile as C++11, supported in ROS Kinetic and newer
add_compile_options(-std=c++11)
Find catkin macros and libraries
if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
roscpp
rospy
std_msgs
message_generation
)
System dependencies are found with CMake's conventions
find_package(Boost REQUIRED COMPONENTS system)
Uncomment this if the package has a setup.py. This macro ensures
modules and global scripts declared therein get installed
See http://ros.org/doc/api/catkin/html/user_guide/setup_dot_py.html
catkin_python_setup()
################################################
Declare ROS messages, services and actions
################################################
To declare and build messages, services or actions from within this
package, follow these steps:
* Let MSG_DEP_SET be the set of packages whose message types you use in
your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
* In the file package.xml:
* add a build_depend tag for "message_generation"
* add a build_depend and a exec_depend tag for each package in MSG_DEP_SET
* If MSG_DEP_SET isn't empty the following dependency has been pulled in
but can be declared for certainty nonetheless:
* add a exec_depend tag for "message_runtime"
* In this file (CMakeLists.txt):
* add "message_generation" and every package in MSG_DEP_SET to
find_package(catkin REQUIRED COMPONENTS ...)
* add "message_runtime" and every package in MSG_DEP_SET to
catkin_package(CATKIN_DEPENDS ...)
* uncomment the add_*_files sections below as needed
and list every .msg/.srv/.action file to be processed
* uncomment the generate_messages entry below
* add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)
Generate messages in the 'msg' folder
add_message_files(
FILES
Num.msg
)
Generate services in the 'srv' folder
add_service_files(
FILES
AddTwoInts.srv
)
Generate actions in the 'action' folder
add_action_files(
FILES
Action1.action
Action2.action
)
Generate added messages and services with any dependencies listed here
generate_messages(
DEPENDENCIES
std_msgs
)
################################################
Declare ROS dynamic reconfigure parameters
################################################
To declare and build dynamic reconfigure parameters within this
package, follow these steps:
* In the file package.xml:
* add a build_depend and a exec_depend tag for "dynamic_reconfigure"
* In this file (CMakeLists.txt):
* add "dynamic_reconfigure" to
find_package(catkin REQUIRED COMPONENTS ...)
* uncomment the "generate_dynamic_reconfigure_options" section below
and list every .cfg file to be processed
Generate dynamic reconfigure parameters in the 'cfg' folder
generate_dynamic_reconfigure_options(
cfg/DynReconf1.cfg
cfg/DynReconf2.cfg
)
###################################
catkin specific configuration
###################################
The catkin_package macro generates cmake config files for your package
Declare things to be passed to dependent projects
INCLUDE_DIRS: uncomment this if your package contains header files
LIBRARIES: libraries you create in this project that dependent projects also need
CATKIN_DEPENDS: catkin_packages dependent projects also need
DEPENDS: system dependencies of this project that dependent projects also need
catkin_package(
INCLUDE_DIRS include
LIBRARIES beginner_tutorials
CATKIN_DEPENDS message_generation roscpp rospy std_msgs
DEPENDS system_lib
)
###########
Build
###########
Specify additional locations of header files
Your package locations should be listed before other locations
include_directories(
include
${catkin_INCLUDE_DIRS}
)
Declare a C++ library
add_library(${PROJECT_NAME}
src/${PROJECT_NAME}/beginner_tutorials.cpp
)
Add cmake target dependencies of the library
as an example, code may need to be generated before libraries
either from message generation or dynamic reconfigure
add_dependencies(${PROJECT_NAME} ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
Declare a C++ executable
With catkin_make all packages are built within a single CMake context
The recommended prefix ensures that target names across packages don't collide
add_executable(${PROJECT_NAME}_node src/beginner_tutorials_node.cpp)
Rename C++ executable without prefix
The above recommended prefix causes long target names, the following renames the
target back to the shorter version for ease of user use
e.g. "rosrun someones_pkg node" instead of "rosrun someones_pkg someones_pkg_node"
set_target_properties(${PROJECT_NAME}_node PROPERTIES OUTPUT_NAME node PREFIX "")
Add cmake target dependencies of the executable
same as for the library above
add_dependencies(${PROJECT_NAME}_node ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
Specify libraries to link a library or executable target against
target_link_libraries(${PROJECT_NAME}_node
${catkin_LIBRARIES}
)
#############
Install
#############
all install targets should use catkin DESTINATION variables
See http://ros.org/doc/api/catkin/html/adv_user_guide/variables.html
Mark executable scripts (Python etc.) for installation
in contrast to setup.py, you can choose the destination
catkin_install_python(PROGRAMS
scripts/my_python_script
DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)
Mark executables for installation
See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_executables.html
install(TARGETS ${PROJECT_NAME}_node
RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)
Mark libraries for installation
See http://docs.ros.org/melodic/api/catkin/html/howto/format1/building_libraries.html
install(TARGETS ${PROJECT_NAME}
ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
RUNTIME DESTINATION ${CATKIN_GLOBAL_BIN_DESTINATION}
)
Mark cpp header files for installation
install(DIRECTORY include/${PROJECT_NAME}/
DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
FILES_MATCHING PATTERN "*.h"
PATTERN ".svn" EXCLUDE
)
Mark other files for installation (e.g. launch and bag files, etc.)
install(FILES
# myfile1
# myfile2
DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}
)
#############
Testing
#############
Add gtest based cpp test target and link libraries
catkin_add_gtest(${PROJECT_NAME}-test test/test_beginner_tutorials.cpp)
if(TARGET ${PROJECT_NAME}-test)
target_link_libraries(${PROJECT_NAME}-test ${PROJECT_NAME})
endif()
Add folders to be run by python nosetests
catkin_add_nosetests(test)
Thank you.

Are you having trouble finding ros/ros.h, or are you talking about VS Code? Or are you talking about the build?

I’m having trouble finding ros/ros.h
Comment by Ranjit Kathiriya on 2021-09-01:
You are getting an error message in the code editor(VS Code, Atom, Eclipse, Pycharm) or in your terminal(when you run code).
Comment by Ranjit Kathiriya on 2021-09-01:
Hello @cyberoverlord,
If you are having issues in Ide (Code editor) then look at this #382798
and if you are having issues while running your code then you have to add this code to your CMakeLists.txt
look over here, https://answers.ros.org/question/237494/fatal-error-rosrosh-no-such-file-or-directory/?answer=237653#post-id-237653
Comment by cyberoverlord on 2021-09-01:
I am still getting no such file or directory
Comment by Ranjit Kathiriya on 2021-09-01:
You are talking about setting.json in VS code?
Comment by cyberoverlord on 2021-09-01:
No, I think it’s the CMakeLists.txt file
Comment by Ranjit Kathiriya on 2021-09-01:
find_package(catkin REQUIRED)
include_directories(${catkin_INCLUDE_DIRS})
find_package(catkin REQUIRED COMPONENTS
...
)
Just copy and past in your CMakeLists file. I think it will work.
Comment by cyberoverlord on 2021-09-01:
I appreciate the help, but it is still giving me the error
Comment by Ranjit Kathiriya on 2021-09-01:
include_directories( include/${PROJECT_NAME} ${catkin_INCLUDE_DIRS} )
Can you please! have a look at your project directory. If it is include/ then you have to add this.

Thanks! I have solved the issue
