What's wrong with parsing the ELF file and trawling out debug information? We can find the
sources and offer them rather than making the user do repetetive labour.

Even after start, can you set line breakpoints on files not in projects? How do you
browse? IIRC, files outside the workspace are missing the breakpoint margin. We added a
"break on function/address" menu item because I couldn't find one in the standard cdt.



Is the challenge really "projectless debugging" or maybe just "minimum setup / overhead
debugging"?



We (Tensilica) built a trivial executable launcher that provides a bunch of command line
args to eclipse.

Then an IStartup listener 

- processes the args
- trawls the binary for files 
  ... and creates a project for free with a linked 
  folder for each of the interesting folders 
  (has source) in the binary. 
- creates a launch

We switched the debug perspective to show the c/c++ projects view instead of the outline
... and voila ... users can browse the source of the image, everything that can be found
is in a project for line breakpoints and things. Also they can terminate and hit F11 to
debug again because of the launch. They can even use the editor to make source changes and
then go outside to type make if that's what hits their button.

How this could become usable for non-Elf and non-gdb based launches I don't know ...
