6.5 doesn't support mingw ?

6.5 doesn't support mingw ?

[luoyi]

I've read from the NEWS that 6.5 version of gdb can support mingw-host,
but when I try to compile it, it give me the err msg:

configure: WARNING: no enhanced curses library found; disabling TUI
configure: error: "*** Gdb does not support native target i686-pc-mingw32"
make[1]: *** [configure-gdb] Error 1
make[1]: Leaving directory `/home/yi.luo/gdb_build'
make: *** [all] Error 2


how can I make it to work under mingw ?

It only supports cross configurations hosted on mingw, unfortunately.

What is missing for it to support the native configuration?

Quite a lot I suspect.  win32-nat.c is only designed to work on Cygwin.
Someone who was interested in native, non-Cygwin-based debugging would
have to work on it, and keep the changes clean enough to not overly
complicate the Cygwin support (per our last discussion on this
subject).  It would probably be at least a few weeks work.

Presumably the people at www.mingw.org have support for the native 
configuration, although I wouldn't like to say if it meets the criteria 
above.

However, AFAICS they are still on GDB 6.3.

They do; but the last time I checked, it didn't, and they haven't shown
any interest in submitting their changes.

Someone obviously did, since I have a native Windows port of GDB 6.3.
(Actually, I also have a gdb-6.3.50.20051116-cvs, but it has several
annoying bugs, so I don't normally use it.)

It's too bad the patches of these ports were not submitted upstream.

I have been working here on a native mingw, and it actually is not
that much work to get something functional. I had to put that project
on hold for a while, however, due to some scheduling conflicts and
business trips. I hope to resume it soon (hopefully in a week or two),
and submit these changes.  The changes I made are against a gdb-6.4
baseline but it shouldn't be a problem to merge them into mainline.

Let me see if I can dig out the patches I already have, if anyone
is interested.
