I've tried to use emacs-gdb. My impression is that it works (you have to 
remember to add --/annotate/=3 argument to gdb, as emacs-gdb suggests) 
adequately. The problem i have is that i'm not accustomed to emacs, 
which makes it difficult to use emacs-gdb comfortably.
The version of emacs i've used was the stock emacs w32 binary, provided 
by GNU, and it is able to use gdb out of the box.

Hello Jeremy -

I have used emacs with mingw for "compiling inside emacs," specifically
using "M-x compile" and then setting the compile command to mingw32-make
(assuming you have a makefile set up).

This opens up a *compilation* buffer, and you can use "C-x `" to parse
the compilation error messages, and position you at the line with the
error.

In my case, this is what used to be called "nt-emacs."  My version is:

   GNU Emacs 23.1.1 (i386-mingw-nt6.1.7600) of 2009-07-30 on SOFT-MJASON

This works for me "out of the box."

I have not used gdb "inside emacs."  I don't use gdb that much, and it
seems a little quirky, at least on windows.

There is a far amount out there about using emacs (for development)
on windows, but I don't know how much is mingw-specific.  However,
as far as I know, emacs is mingw-agnostic, so the build tools you
use really shouldn't matter.

There are a lot of ide-like emacs packages -- code browsers and
similar stuff -- but I never got them working properly on windows.

Sorry I can't point you to specific references -- it's been a while
since I looked into this.

I use gcc/gdb within Gnu emacs all the time. It works very well with 
MinGW. This is my main C++ development environment.

The secret is to run emacs from a MinGW shell rather than from the Start 
menu shortcut so that it picks up all the right environment settings.

You will also need to set environment variables needed by emacs in your 
.profile, here's mine:

   export PATH=/c/emacs/bin/:$PATH
   export SHELL=sh
   export EDITOR=emacsclient

You also need HOME set correctly, but that is probably already OK if you 
have a working MinGW shell.

Then just start emacs from an MSYS command line:

   $ emacs &

The compile, recompile and gdb commands then all work as on Linux.

I think Andy actually means an MSYS shell, running in its (default)

Thanks -- that really helped.
One of the challenges is that you can get various things to "kind of
work" and be quite misleading as to what really should be done.

I do have two questions:
1) When I start msys, or do a compile inside emacs, there's a very long
pause, maybe about 30s or so. Is that normal?
2) I get the dreaded "control chars" or whatever in the shell... I can't
remember how to remove them.... here's an example:

$ pwd
/c/wxWidgets-2.8.11/build-debug/samples/image
]0;MINGW32:/c/wxWidgets-2.8.11/build-debug/samples/image

[32mjgreene@...
[33m/c/wxWidgets-2.8.11/build-debug/samples/image[0m
$

Thanks!

Can't comment on usage from within emacs, because I don't do that.  MSYS
shell start-up is almost instantaneous for me, but I have experienced
horrendous delays, when starting from a USB flash drive, on a machine
with a particularly aggressive virus scanning configuration.

Looks like a problem with the terminfo emulation.  What container is
the shell running in?  What is the setting of $TERM?  Is it properly
exported?

These are ANSI terminal control sequences, presumably originating from
the prompt.  You could modify the setting of $PS1, to remove colour
options, but it would be good to try to identify why the terminfo layer
isn't interpreting them correctly.

No, not for me. I get near-instant response.

Sorry, forgot an environment variable to set in your .profile:

   # set the prompt to something simple so emacs doesn't get confused
   export PS1='MinGW:\w: '

This is because the default in bash seems to be to support colourisation 
of the prompt and emacs can't handle that.

BTW: Some might say that should read 'MSYS:\w: '! I put this in the 
prompt to remind me whether I'm in an MSYS shell or a Cygwin shell since 
I use both but keep them completely separate.

Note that \w substitutes the current path. Omit it if you don't need 
that in your prompt.

I assume it's the same delay that I'm getting when compiling in emacs.

Re: [Mingw-users] slow msys startup (was emacs with windows)

From: Jeremy Greene <jeremy@Ze...> - 2010-11-24 19:08

Interesting... if I disable all network interfaces and then start
msys.bat it is instantaneous to the bash prompt.
Prior to this I did delete all mapped drives and even all items in "my
networks".
Does this ring a bell with anyone?!

Sorry, forgot an environment variable to set in your .profile:

   # set the prompt to something simple so emacs doesn't get confused
   export PS1='MinGW:\w: '

This is because the default in bash seems to be to support colourisation

of the prompt and emacs can't handle that.

BTW: Some might say that should read 'MSYS:\w: '! I put this in the 
prompt to remind me whether I'm in an MSYS shell or a Cygwin shell since

I use both but keep them completely separate.

Note that \w substitutes the current path. Omit it if you don't need 
that in your prompt.

Re: [Mingw-users] slow msys startup (was emacs with windows)

From: Jeremy Greene <jeremy@Ze...> - 2010-11-24 22:01

Ok... used wireshark to get an idea on what's going on.
What I see is that when the bash shell starts it sends out a netbios
name query to admin-server.
It also sends a dns request for the same name. The dns server does
respond (it's in Comcast land).
Then bash sends a ping to the resolved address... which of course won't
typically work these days.
Bash repeats the NB query and ping for 25 seconds or so.
So, I added admin-server to my windows hosts file (to 127.0.0.1).
Curiously, it still pauses, but only for a few seconds. 

So it's at least workable for me, but there seems to be some
configuration that I have incorrect, or something probably should be
fixed in bash or msys?

Interesting... if I disable all network interfaces and then start
msys.bat it is instantaneous to the bash prompt.
Prior to this I did delete all mapped drives and even all items in "my
networks".
Does this ring a bell with anyone?!

I assume it's the same delay that I'm getting when compiling in emacs.
I will have to figure that out for it to be usable :(

This is odd, because when I start MSYS, Wireshark shows no packets of 
any kind.

I'm running MSYS using the msys.bat file, which brings up a cmd.exe 
(i.e. I'm not using any kind of console application) with bash running 
in it.

What are you doing? Are you using a console program of some kind?

Re: [Mingw-users] slow msys startup (was emacs with windows)

From: Jeremy Greene <jeremy@Ze...> - 2010-11-25 00:08

I normally use msys.bat to start the shell. But I experienced the delay
when I started a windows CMD window and just stared bash.exe. Or when in
emacs and did the compile command (in that case, I started emacs from an
msys shell that was started using msys.bat).

Also, I recently installed mingw, using the app get program as
instructed on the site. But I did have cygwin installed at the time. It
is certainly possible that something funny happened in the install. But
I think it would have to be some conflict with an existing software
package of some form since I really think that the mingw install was by
the book.

In all, getting very cool, but it has taken quite a bit of time. And
kind of a litany of "little thing". 
Like emacs' next-error function not getting the file name correct...

There are too many variables that may cause this for one person and not
another.  Besides the physical local hardware there is the network
interfaces for any mapped drive.  If the physical drive of a mapped
drive isn't available, it will sorely exacerbate the amount of time due
to the number of retries and timeouts for each try for the connection
establishment.  You may be able to work around this by starting an MSYS
shell while working in emacs so that the MSYS dll remains in memory and
preventing the DLL initialization with each command.  I've occasionally
considered writing a persistent MSYS application just to add to the
START folder but I don't have much need of it so have never gotten to it.

No, it has nothing to do with the install and everything to do with your
Windows environment and in particular the network mappings.

Huh? What the is wrong with the posting?!
And if you actually read what I wrote, I deleted all network maps other
window network connections.
Geeze... I thought I went the extra mile in figuring out what's going
on. So rude!!
Given that it is suppose to work in windows, seems kind of funny to
dismiss a problem based on a particular windows
configuration? Wouldn't it be good to identify it and either fix it or
document it somewhere (and it may be, but I haven't found it or been
pointed to it).

Uh, Oh... maybe I annoyed you with the mingw being "dead, old fork" of
cygwin?! Sorry. I note that no one responded to that. Still interested
though.
