What is the difference between GDB and Cygwin GDB? [message #63435]

I am using MinGW without Cygwin. When I am trying to debug with "GDB", I get
this message:

Failed Launching CDI Debugger : No symbol "auto" in current context.

So even I do not have installed Cygwin, I tried using "Cygwin GDB" and can
debug.

Can anybody tell me what the difference of that two is and why I need to use
"Cygwin GDB" when I do not have installed Cygwin? I'm new to GNU tools (used
MSVC before) and I'm a bit confused now?!

Thanks
Markus

What version of gdb is installed wiht your MinGW installation?
The CDT uses GDB version 5.2.1 as the default. If you are using Cygwin the
default version they currently install is too old. You need gdb 5.2.1, which
should be in the gdb package dated 20020718-1

You should use "Cygwin" on Windows because there are features (like
automatically loading of shared libraries etc) that are not supported.

I am using the latest download of MinGW, including
gdb-5.1.1-1

So I think I should lookup if there is some patch on the MinGW site to
update to GDB 5.2.1

Thanks!

Hello,

Could you tell me more about Cygwin advantages over MinGW for CDT on
Windows?

Thanks

Sorry, I wasn't clear. I mean you should select "Cygwin GDB Debugger".
Otherwise CDT tries to set the "Load shared library symbols automatically'
option on/off and gdb returns the error message "No symbol "auto" in current
context." because this feature is not supported on Windows.
I don't know much about MinGW so I can't tell what is the difference between
it and Cygwin.
