Hi thomas,, Thank you for the reply! How should I call the setup file inside qt? The problem is: every time I use any function in rclcpp, for example, `rclcpp::init(arg, argv)`, qt would crush at run time. No error message from Qt it simply crushes. Building in Qt was fine. For testing you can just import the two libraries: rclcpp and PocoFoundation. Everything was working fine on Beta1 with Qt. Only with the Beta2 version, I have this problem. --- [Visit Topic](https://discourse.ros.org/t/ros2-beta2-how-to-include-the-rcl-into-qt/2547/3) or reply to this email to respond.
