Failing to include header files from packA/include/packA/ in packA and packB
Hello guys, i wrote a .cpp and a .h file containing a function that should be used by multiple nodes.
test.cpp
#include <test.h>
float addAB(float a, float b) {
float r;
r = a + b;
return r;
}
test.h
float addAB(float a, float b);
I have 2 roscpp packages: packA and packB, with the nodes packA_node.cpp and packB_node.cpp.
test.cpp and test.h are inside /packA/include/packA/
Now i want them to be used by both packA_node.cpp and packB_node.cpp
I tried including them as #include <test.h>, #include "test.h" and #include <packa include="" packa="" test.h="">, but none of them work. The header file test.h cant be found.

## 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
# Message1.msg
# Message2.msg
# )
## Generate services in the 'srv' folder
# add_service_files(
# FILES
# Service1.srv
# Service2.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
# geometry_msgs# nav_msgs# std_msgs

Please remove all the boilerplate comments from the
CMakeLists.txt
you show.About 95% of those lines could be deleted, and we would only be missing comments.
Also: there are quite a few older Q&As about this. Searching with Google (
include header other package site:answers.ros.org
) leads me to #q201977, #q285472, #q279929, #q249055, #q54010 and many others.Could you try searching yourself and tell us whether any of the older Q&As clear things up for you?
then please tell us what you have read and tried, so we don't end up suggesting the same things.
