Look at the Project window, where the files are displayed. There's a column at the far right which has a little green bug at the top. This column indicates whether the tools generate debug symbols for the file. If there's not a little black dot in this column adjacent to your plugin's file name, then no debug symbols are being generated. Click on the row that the file name is on, in this column, and the black dot should appear. Now you'll get your debug symbolics. HTH,
