I don't use Eclipse, so I'm stabbing in the dark here.  The error
message means that there's some problem between Eclipse and the
underlying debugger with respect to GDB/MI commands emitted by
Eclipse.  Google finds several discussions for these error messages,
so maybe you will b  e able to find a solution there.

An alternative is to use the Emacs's front-end for GDB, it is started
with "M-x gdb RET".
