CLion

In Clion you can setup different toolchains to build your Motorcortex applications. Using the Motorcortex ToolChains plugin you can easily setup the toolchains needed for cross-remote development.

Install Motorcortex SDK

1. From the Motorcortex store download the latest Motorcortex SDK for your system, for example mcx-rtos-glibc-x86_64-mcx-image-dev-corei7-64-mcx-intel-toolchain-2025.03-0-g0e9d0e9.sh.

2. Give the file execution permissions: (Replace the filename with the one you downloaded)

   chmod +x mcx-rtos-glibc-x86_64-mcx-image-dev-corei7-64-mcx-intel-toolchain-2025.03-0-g0e9d0e9.sh
   

3. Run the installer: (Replace the filename with the one you downloaded)

   ./mcx-rtos-glibc-x86_64-mcx-image-dev-corei7-64-mcx-intel-toolchain-2025.03-0-g0e9d0e9.sh
   

4. Follow the instructions on screen to complete the installation. Make sure to remember the installation path, you will need it in the next step.

Make sure to install the SDK that matches your Motorcortex controller version. You can check your controller version by running cat /etc/issue on the controller terminal.

System Toolchain

1. In the Main Menu on the top left corner open: File → Settings, then find the Build, Execution, Deployment → Toolchains menu.
2. Add a new toolchain by pressing the button and select system.
3. Rename it to motorcortex! (Do not give it another nam and this is case-sensitive)
4. Add environment by pressing Add environment and selecting from file. In the Environment file path enter the path to the mcx-clion-environment.sh file in the Motorcortex SDK installation directory.

   

5. Change the build tool to make if it is not already selected. (Ninja is supported but it will give a warning in the CMake window which can be ignored)
6. Press Apply to save the toolchain settings.

   

7. Remove the default toolchain or move it below the motorcortex toolchain to make sure the Motorcortex toolchain is used by default.

Remote Host

For this step, make sure you are connected to your Motorcortex controller via Ethernet. See Connecting to your Motorcortex Controller for more information.

1. In the Main Menu open File → Settings under Build, Execution, Deployment you will find the Toolchains menu.

2. Add a new toolchain by pressing the button and select Remote Host.

3. In the Credentials: press the button to enter the SSH Configurations menu. Add a new configuration by pressing the button and fill in the following data:

   • Host: 192.168.2.100 or the IP address of your Motorcortex controller if you changed it.
   • Port: 22
   • User name: admin or your custom username if you changed it.
   • Password: vectioneer or your custom password if you changed it.

4. Press the Test Connection button to make sure your connection is OK. If not, re-check your controller connection.

5. If the connection is good you can press OK to close the SSH Configurations menu.

6. Wait for Cmake and the C/C++ Compiler to be detected:

   • CMake: Remote host CMake
   • Build Tool: Default, Detected: make
   • C Compiler: Default, Detected: cc
   • C++ Compiler: Default, Detected: c++
   • Debugger:Remote Host GDB

7. Press the Apply button to save the Toolchain settings.

Run/Debug Configurations

To easily build and run your Motorcortex application from within CLion you can setup Run/Debug configurations for both cross-compiling and remote development. With the Motorcortex ToolChains plugin this is also made easy.

1. In the top bar select and select configuration edit....

   

2. Press the button to add a new configuration and select Motorcortex Remote Application.

3. You can name the configuration as you like, for example mcx-example.

4. In the Program arguments field add the following:

   -s -c /etc/motorcortex/config/config.json
   

5. Make sure that the Deployment profile automatically selected Remote Host ($ID$) as the option, with $ID$ being the ID of your remote host toolchain.

   If you cannot see Remote Host for your IP, see the instructions below.

6. Press Apply to save the configuration.

When you pressed apply it should have automatically created two new folders in your project directory: cmake-build-crossdebug and cmake-build-crossrelease. In the Cmake window of Clion a warning might appear but this can be ignored:

CMake Warning:
  Manually-specified variables were not used by the project:

    CMAKE_VERBOSE_MAKEFILE

Create new Deployment profile

1. In the Main Menu open Tools → Deployment and click on configurations....
2. Add a new SFTP and enter the prefered name, for example Remote Host.
3. Add the SSH configuration that you use to connect to the target machine.
4. Select Use rsync for download/upload/sync. (This will make it faster)
5. Press OK.
6. You should now be able to use the Remote Host in the Run/Debug Configurations menu

Using the Toolchains

Compiling and Debugging/Running

1. In the top right corner of CLion select the Run/Debug Configuration you created earlier, for example mcx-example.
2. To build the application press the button.
3. To run or debug the application press the or button.

Installing and Running your Application Remotely

1. In control/MainControlLoop.cpp, change the current iterateOp function to the following code:

      bool MainControlLoop::iterateOp_(const container::TaskTime &systemTime, container::UserTime *userTime) {
         log_info("Test");
   
         return true;
      }
   

2. In CLion set your Run/Debug Configuration to Remote Host.

3. Press Install (Located under build in the top bar). This will install the application on the Motorcortex controller.

4. After installation is complete, open a terminal, either in CLion or your system terminal.

5. Run the following command to ssh into the the Motorcortex controller: (Update the Username and IP address if needed)

   ssh admin@192.168.2.100
   

6. Once logged in, run the following command to restart the Motorcortex application:

   sudo motorcortex restart
   

7. Run the following command to view the output logs:

   mcx-lastlog
   

8. You should see the Test log message appearing every control loop iteration.

For more information on control application development, please refer to the Developing Control Applications section of the documentation.

Common issues

If you encounter issues while setting up or using the Motorcortex toolchains in CLion, here are some common problems and their solutions:

• fatal error: mcx/core.h: No such file or directory: This error indicates that the Motorcortex SDK is not properly configured in the toolchain. Make sure you have the motorcortex toolchain as the top priority toolchain and that the environment file path is correctly set to the mcx-clion-environment.sh file in the Motorcortex SDK installation directory. Remove the Default toolchain if necessary or move it below the motorcortex toolchain. Remove the cmake-build directories and press Reload CMake Project in CLion.

• Removing Cmake-build directories: If you encounter build issues, try removing the cmake-build-crossdebug and cmake-build-crossrelease directories in your project folder. This will force CLion to regenerate the build files and can resolve various build-related problems.
