[dsdp-tm-dev] RE: eclipse remote deubgging bug or my error?

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

The point is that when you want gdbserver, you need
A LOCAL gdbprogram that can read and understand the
Target architecture - in other words, a cross debugger.

Your LOCAL cross debugger reads the code that is compiled
For REMOTE and does the actual debugging.

Since this is really an FAQ, I created an FAQ entry:
http://wiki.eclipse.org/TM_and_RSE_FAQ#How_can_I_do_Remote_Debugging_with_CDT.3F
Let me know if anything is still unclear.

Cheers,
