Hi, I just did a test. From the debugger plugin's log message, I can see a line like below:
[debug]>>>>>>cb_gdb:
[debug]> directory F:/code/image-label-gui/
[debug]Source directories searched: F:/code/image-label-gui;$cdir;$cwd
[debug]>>>>>>cb_gdb:
[debug]> set args abc
[debug]>>>>>>cb_gdb:
[debug]> run
[debug]Starting program: F:\code\image-label-gui\bin\Debug\ImageLabelGui.exe abc
...
So, the argument "abc" is passed to the debugee as I can see.
