I selected
foo.c (source code)
in the Target entry of Debugger's Target tab.
I've changed this into
foo.o (the binary GCC generated)
,then I can do debugging successfully.

Where is "Delete"? I can't find it.
And by hitting "Delete",can I erase the names of past files,too?
It may be a trivial thing though.
