The “libglade-WARNING **: could not find signal handler ‘gpass_authentication_on_response’” error occurs when the libglade library cannot find the signal handler for a particular function, in this case ‘gpass_authentication_on_response’. This can happen if the signal handler function is not defined in the Glade file or is not properly linked to the main program.
To solve this error, you can do the following:
- Check the Glade file: Open the Glade file in a text editor and search for ‘gpass_authentication_on_response’. Make sure that the signal handler function is defined in the Glade file and the function name is spelled correctly.
- Check the source code: Check the source code of the main program and make sure that the signal handler function is defined and linked properly. The function signature in the source code should match the signal handler function defined in the Glade file.
- Update the signal handler: If the signal handler function is missing or not properly defined, you can update the Glade file to include the correct signal handler function. Open the Glade file in Glade editor and add the signal handler function to the ‘Signals’ tab of the relevant widget.
- Rebuild the application: After updating the Glade file or source code, rebuild the application to link the new signal handler function.
After following these steps, the “libglade-WARNING **: could not find signal handler ‘gpass_authentication_on_response’” error should be resolved.
