Remote GDB Server

Go to Run | Edit Configurations, click , and select Remote GDB Server from the list of templates.

Specify the following settings:

• Target and Executable

  Select the target to be built (CMake, Makefile, or custom target) and the executable to be uploaded remotely.

  Click the button to configure custom targets in the Settings / Preferences | Build, Execution, Deployment | Custom Build Targets dialog.

• GDB

  Select the client debugger: bundled multiarch GDB (default), one of the toolchain debuggers, or a custom GDB binary.

• Credentials

  Select one of the existing SSH configurations from the drop-down list or click to create a new one. Provide the credentials for accessing your remote machine:

  

• Upload executable

  Your executable can be uploaded every time you start a debug session (Always) or upon the changes in the binary (Updated Only). You can also choose to skip uploading (None).

• Upload path

  Specify the remote folder where the executable will be placed.

• 'target remote' args

  Provide the medium to carry debugging packets (serial line or an IP network using TCP or UDP). See gdb documentation for more details on connecting to a remote target.

• GDB Server

  Set the location of gdbserver on the remote machine. The default path is filled up automatically.

• GDB Server args

  Specify the arguments that will be passed to gdbserver: connection port, executable path, and additional arguments if required.

  By default, this field contains the port you provided in 'target remote' args and the path from Upload path followed by the binary name.

Make sure to select GDB as your toolchain debugger.

• On macOS and Linux, go to Settings / Preferences | Build, Execution, Deployment | Toolchains and select one of the available GDB options in the Debugger field of the current toolchain.

• Note that on Windows, Remote GDB Server configurations can't be used with the Visual Studio toolchain since the debugger it employs is based on LLDB.

After placing breakpoints in your code, select the newly created Remote GDB Server configuration, and press (Shift+F9).

• You can find the build log in the Messages tool window:

  

• To monitor the process of uploading, switch to the File transfer window:

  

• The Console tab of the Debug tool window shows the status of the GDB/gdbserver connection:

  

You can debug the program as usual: examine the variables, step through, evaluate expressions, and use all the other debug features.
