I defined my interface to include sensor_msgs as following:
sensor_msgs/Image rgb
int64[] classes
but got that error fatal error: sensor_msgs/msg/detail/image__struct.hpp: No such file or directory 19 | #include "sensor_msgs/msg/detail/image__struct.hpp"
You may need to declare a build dependency on sensor_msgs, so that CMake will locate the headers from the sensor_msgs package when building yours.
Check the package.xml of the package you're trying to build and add the following if it's not already there:
<depend>sensor_msgs</depend>
You can copy the example_interfaces package as an example.
If that is not your issue, please update your original question to show the package.xml you are using and we can take a look at that!
I added DEPENDENCIES sensor_msgs rosidl_generate_interfaces(${PROJECT_NAME} ${srv_files} DEPENDENCIES sensor_msgs ) and cleaned the workspace with the same package xml and now it works. It looks like it is recommened to clean the workspace before new compilation
Here is my CMakeLists.txt and package.xml
cmake_minimum_required(VERSION 3.5) project(detectron_interface)
if(NOT CMAKE_C_STANDARD) set(CMAKE_C_STANDARD 99) endif()
if(NOT CMAKE_CXX_STANDARD) set(CMAKE_CXX_STANDARD 14) endif()
if(CMAKE_COMPILER_IS_GNUCXX OR CMAKE_CXX_COMPILER_ID MATCHES "Clang") add_compile_options(-Wall -Wextra -Wpedantic) endif()
find_package(ament_cmake REQUIRED)
find_package(sensor_msgs REQUIRED) find_package(rosidl_default_generators REQUIRED) set(srv_files "srv/Detectron.srv" ) rosidl_generate_interfaces(${PROJECT_NAME} ${srv_files} DEPENDENCIES sensor_msgs ) ament_export_dependencies(rosidl_default_runtime) ament_package()

<test_depend>ament_lint_auto</test_depend> <test_depend>ament_lint_common</test_depend>
<export> <build_type>ament_cmake</build_type> </export> </package>`
The problem still persists! Can you guide me on that
try replacing
<build_depend>rosidl_default_generators</build_depend>
with
<buildtool_depend>rosidl_default_generators</buildtool_depend>
you may also need to add
<exec_depend>sensor_msgs</exec_depend>

I had a similar error and my guess is that your CMakeLists.txt file or package.xml file is incorrect, but it's hard to tell without more information.
