Does anyone know of a plugin or plans to support Qml files in clion? Qml, part of a highly used C framework (Qt), really needs at least syntax highlighting in CLion. It is weird to go to another IDE (slickedit in this case, or command line vim) to edit those files, just so I can see if I. If you are working on a Qt-based project in CLion, you'll be happy to learn that Clazy, a Qt-specific code analyzer, is now integrated into CLion's Clangd-based engine. You'll now get Clazy checks and quick-fixes right in the editor! I checked out 8e46a3072b3aef2b4612cdc5232510 from qtbase, configured with./qtbase/configure -debug -opensource -developer-build -confirm-license.
Hello,
i am totally newbie with Jetson Nano and i have some questions about Nano and C++ (in fact, i am a newbie for many things concerning Jetson Nano) :
Does Nano Developer Kit provides the tools to be able to create C++ programs ?
My purpose is to create C++ programs using Opencv and Cuda.
I suppose a C++ compiler is provided. If the answer is yes, which compiler is it ?
Is there an IDE for C++ provided with the developer kit ? If yes, which one, if no, which IDE pour C++ would you recommend to me ?
Is GTK+ provided with the developer kit ? It seems Qt is not provided with the Nano dev kit (we have to compile Qt if we want to use it. Am i correct ?
Would i prefer Qt rather than GTK+ ? If yes, why ?
To get opencv with Cuda, i suppose i must compile opencv 4.1.0 ?
I think i can manage opencv but concerning Cuda, do you have a pdf document which explains Cuda, step by step ?
I will make image treatment, using routines like blur, gaussain blur, denoise, sharpen, unsharp mask, histogram stretch, Clahe filter, etc. If i have to write those filters using Cuda, do you have some documentation about how to use Cuda to make such filters ?
In fact, i would like first to setup Jetson Nano to get working environment to create C++ software using opencv, Cuda, GTK+ (or Qt) quite quickly because i don't want to spend too much time getting a working environment. I would prefer to spend my time learning C++, Cuda and GTK+ (or Qt) to develop my software.
Many thanks for your highlights !

ROS (Robot Operating System) is a set of libraries and tools designed for robot applications. It mainly targets C++ and Python development and uses catkin build system, which is based on CMake with Python scripts. ROS software distributions are available for Linux, Windows, and also for macOS in experimental mode.
You can use CLion as an IDE for your ROS projects. This tutorial describes how to set up the workflow and gives an example of creating a ROS package and working with it in CLion. Note that this setup procedure has been tested on Ubuntu.
There are also 3rd party plugins that you can use for ROS development in CLion: ROS-Robot Operating System and Hatchery.
Note: 3rd party plugins are not maintained or supported by the CLion team.
Launch CLion in the sourced environment
CLion needs to be informed of the ROS-specific environment variables. These variables are retrieved in the current shell when you source the workspace by running the following command from the workspace directory:
The simplest way to provide CLion with ROS environment variables is to launch the IDE from the same shell. After the workspace is sourced, you can type in the same terminal:
Open a ROS project in CLion
After you have launched CLion in the sourced environment, do one of the following to open your ROS project:
Click File | Open and select CMakeLists.txt in the src directory of your ROS workspace, then choose Open as Project.
Ive got a new LG Stylo 5, is there a way to screen mirror to a tv with no internet connection? The tv is not a smart tv but has HDMI in. I have no Internet access other than the 4g lte on the phone, no wifi available. Lg stylo 5 manual. On Galaxy devices the screen mirroring feature is called Smart View. You can easily mirror your screen with Smart View by just tapping the Smart View icon and doing a few simple steps. For iPhones, the screen mirroring feature is called AirPlay, and it does the same exact thing - mirror. Here's how to share your screen or media files with another screen (TV, game console, etc.) using your Stylo 5. Due to inactivity, your session will end in approximately 2 minutes. Extend your session by clicking OK below. Due to inactivity, your session has expired. But in order to connect LG Stylo 5 to a TV wirelessly, the latter must support Smart TV technology. Otherwise, you will only be able to connect the devices using a cable. Via Wi-Fi Direct. Wi-Fi Direct is a feature supported by most smart TV models. It allows you to display the image from the screen of LG Stylo 5 to the TV.
Click File | New CMake Project from Sources and select the src directory of the workspace to import the project from.
The CMake tool window will show the status of the project loading:
If you are using catkin_tools, there is no top-level CMakeLists.txt for the whole workspace. In this case, you will need tp open each package as a separate project in CLion (choose CMakeLists.txt from the package directory). Feature request for catkin_tools support in CLion: CPP-7438.

Set build paths to the catkin workspace
By default, CLion places build output in cmake-build-debug or cmake-build-release directory that is created automatically. For ROS development, it means that you will have two different builds in CLion and in the console where you run catkin_make.
To have a single build across the IDE and console, you need to set CLion build paths to the catkin workspace directories. For this, go to File | Settings Ctrl+Alt+S | Build, Execution, Deployment | CMake and change two fields:
In Build directory, set /build.
In CMake options, add
-DCATKIN_DEVEL_PREFIX:PATH=/devel.
Work with launch files
You can run and debug ROS nodes as regular applications in CLion.
Launch files cannot be executed directly, but you can edit them with XML syntax highlighting and completion, and attach the debugger to a running node.
Attach the debugger to a running node
Run your .launch file from the command line. For example
You can check the list of currently running nodes by the
rosnode listcommand. In our example, the list will containtalkerandlistener:Call Run | Attach to Process from the main menu or press Ctrl+Alt+F5.
Connect to the desired node by its PID or name:
Example: create a basic ROS node, edit and run it in CLion
In this example, we will create a simple ROS package, edit the source code, and run the node from CLion. We will use ROS Melodic on Ubuntu 18.04 and the basic publisher node from the Writing a Simple Publisher and Subscriber (C++) tutorial available on the ROS wiki.
Create a basic ROS package
Create and build a ROS workspace:
mkdir -p ros_workspace/src cd ros_workspace catkin_makeIn the workspace, create a package called my_package:
cd src catkin_create_pkg my_package roscpp rospy std_msgs

Launch CLion
Source the workspace:
And launch CLion in the same terminal:
sh /opt/clion-2018.2/bin/clion.sh
Open the package as a project in CLion
In CLion, go to File | Open and select the CMakeLists.txt file located inside the package folder, and choose to open it as a project:
Add a source file and edit CMakeLists.txt
Add a new source file to the project: right-click on src in the Project tree, select New | C/C++ Source File and call it my_package.cpp.
Copy the entire talker.cpp file from the Publisher and Subscriber tutorial into my_package.cpp.
Add the newly created source to CMakeLists.txt and link it against catkin libraries:
add_executable(my_package src/my_package.cpp) target_link_libraries(my_package ${catkin_LIBRARIES})After that, reload the CMake project, and notice my_package in the list of Run/Debug configurations:
Run a ROS node
Clion Qt Plugin Chrome
Before running the node from CLion, open the ROS master in a new terminal:
In CLion, Run the my_package configuration. Run tool window will show the node output:
In a separate terminal, check the currently active ROS topics.
If we print the messages from
chatter, the output will be similar to what we can see in CLion:Now if we stop the application in CLion, the
rostopic echo /chattercommand will have no output.
