Code::Blocks GDB Cannot Open file Error

Question

I use Code::Blocks 12.11 and Cygwin gdb in Windows 8. I configured the cygwin gdb in code::blocks, when debug, it reports "cannot open file" error. Using gdb in command line is alright.

I found this discussion from web, but I cannot find the registery entry. My guess is that the Debugger plugin cannot pass a right path name to gdb, there is ">>" in prefix of the path, i copied this into editor and it turns out to be two "sub" charaters (1A in ascii).

Here is the error log, the ">>" is added by hand, because when I copied it here, the "sub" charaters don't show.

Debugger name and version: GNU gdb (GDB) 7.6.50.20130728-cvs (cygwin-special)
Child process PID: 21936
Cannot open file: >>/cygdrive/e/code/test/main.cpp
At >>/cygdrive/e/code/test/main.cpp:17
Debugger finished with status 0

My question is

1.How can I make the gdb work in the Code::Blocks

2.Are the two "sub" charaters normal and why do they appear, how can I remove it.

I tried it in Windows 7-64, still the same

I made it work by doing the following:

I added a String Value under

HKEY_CURRENT_USER\Software\Cygnus Solutions\Cygwin\mounts v2

and

HKEY_LOCAL_MACHINE\Software\Cygnus Solutions\Cygwin\mounts v2

(none of the folders were there, so I had to create them manually by selecting New->Key)

with the following parameters:

name: cygdrive prefix

value: /cygdrive

thanks very much for your help, I don't know a lot about the registry things, but your answer really solved my problem

I confirm this is still the fix in Codeblocks 13.12, and the key under HKEY_CURRENT_USER is sufficient.

What if you are using Ubuntu ?

Then I would not need cygwin, which is not the point of this question.

I did this baffling answer but failed. Maybe I did it wrong? It needs a much clearer explanation please.
