Catkin/Cmake includes directories as -isystem (Custom OpenCV)
Hello,
I am trying to get a custom-built version of OpenCV 3.3.0 (with CUDA-support) to work with ROS Kinetic on a NVIDIA Jetson TX1.
OpenCV is installed to /usr/local
.
I have tried following this and this answer, but they didn't work for me.
My CMakeLists.txt
-file (currently) looks like this:
cmake_minimum_required(VERSION 2.8.3)
project(<project_name>)
find_package(
OpenCV 3 REQUIRED
NO_MODULE
PATHS /usr/local
NO_DEFAULT_PATH
)
find_package(catkin REQUIRED COMPONENTS
cv_bridge
# ... others ...
)
include_directories(
${OpenCV_INCLUDE_DIRS}
${catkin_INCLUDE_DIRS}
)
# add_executable, add_dependencies...
target_link_libraries(<node_name>
${OpenCV_LIBRARIES}
${catkin_LIBRARIES}
)
I also downloaded and built the vision_opencv
-package in my workspace.
When building a node, Cmake finds the correct version of OpenCV.
-- Found OpenCV: /usr/local (found suitable version "3.3.0", minimum required is "3")
However the node still includes the wrong header-files and is linked against the ROS-OpenCV-Version, as I can find out at Run-Time in my code. Looking at the build-commands with VERBOSE=1 I can see that the include-directories are part of the command, but are included with the -isystem
-Flag, meaning the ROS-Includes (included with -I
) will be preferred.
/usr/bin/c++ -DROSCONSOLE_BACKEND_LOG4CXX -DROS_BUILD_SHARED_LIBS=1 -DROS_PACKAGE_NAME=\"<package_name>\" -isystem /usr/local/include -isystem /usr/local/include/opencv -I<workspace>/src/vision_opencv-kinetic/cv_bridge/include -I/opt/ros/kinetic/include -I/opt/ros/kinetic/include/opencv-3.2.0-dev -I/opt/ros/kinetic/include/opencv-3.2.0-dev/opencv -I/opt/ros/kinetic/share/xmlrpcpp/cmake/../../../include/xmlrpcpp -std=c++11 -o CMakeFiles/<node_name>.dir/src/<node_name>.cpp.o -c <workspace>/src/<package_name>/src/<node_name>.cpp
This is the linker command. I tried to shorten it a bit by using <ros_libs>=/opt/ros/kinetic/lib
and <local_libs>=/usr/local/lib
.

Are we sure it's not the ROS OpenCV package setting the
isystem
flag? Related issue: ros/catkin#428 (but it's old, so just for reference).I'm not sure, but I don't think so. I've tried adding Paths manually in include_directories, and I discovered something weird: When I add
/usr/local
it gets added to the command with the-I
-flag like it should. However when I manually add/usr/local/include
it gets added with-isystem
.
