Launching an application

Launching an application without the debugger

To launch an application without the debugger, follow the steps below:

Launching an application with the debugger

You can launch an application with the debugger or, if your application is already running without the debugger, you can attach the debugger to it.

To launch an application with the debugger using the Explorer interface, follow the steps below:

1. From the workspace, right-click the program's project folder.
2. Navigate to QNX and open the dropdown menu on the right.
3. Click Debug as QNX Application....
4. Select the launch configuration for debugging. The QNX Toolkit runs and debugs the program.
   Note:

   Alternatively, to debug your application, click the Bug icon in the Primary Side Bar to open the RUN AND DEBUG view. Then, select your launch configuration from the dropdown list and press F5.

Attaching the debugger to a running application

If you've previously launched your QNX application without the debugger, and want to attach the debugger to it while it is running, follow the steps below:

1. From QNX TARGETS, expand the PROCESSES folder.
2. Right-click on a process on the target which you previously launched.
3. Click Attach Debugger to QNX Process. The IDE attaches the debugger to the selected process and stops execution immediately. The RUN AND DEBUG view displays information about the active threads and their stack frames.

Workaround for postmortem debugging

While postmortem debugging of core files isn't supported, you can implement a workaround by adding the following code snippet to your launch.json file:

{
    "version": "2.0.0",
    "configurations": [
       {
          "type": "cppdbg",
          "request": "launch",
          "name": "QNX: debug core dump",
          "program": "${workspaceFolder}/myprogram",
          "stopAtEntry": false,
          "coreDumpPath": "${workspaceFolder}/myprogram.core",
          "cwd": "${workspaceFolder}",
          "MIMode": "gdb",
          "miDebuggerPath": "${env:QNX_HOST}/usr/bin/ntox86_64-gdb"
       }
     ]
}
