have now installed GTK+ and MinGW

NATIVE BUILD OF QEMU ON W32 WIN7

[...]

I downloaded the all-in-one bundle from http://www.gtk.org/download/win32.php

called gtk+-bundle_3.6.4-20130921_win32

good

I read this tutorial http://www.gtk.org/download/win32_tutorial.php

1) extracted files to a new folder which I named C:\gtk

2) changed my path variable by adding:

  ;c:\gtk\bin

good, too.

3) typed in at Command Prompt:

  pango-querymodules > gtk\etc\pango\pango.modules

  gdk-pixbuf-query-loaders > gtk\lib\gdk-pixbuf-2.0\2.10.0\loaders.cache

  gtk-query-immodules-3.0 > gtk\lib\gtk-3.0\3.0.0\immodules.cache

4) tested by typing in terminal

  gtk3-demo

All seemed well!

FOLLOWING UP ON PETER MAYDELL ADVICE PART 3

NATIVE BUILD OF QEMU ON W32 WIN7 

USE THE 32 BIT VERSION OF MINGW-W64

So to try and implement Mingw-w64 32bit version

(http://mingw-w64.sourceforge.net/) instead of mingw32 (http://www.mingw.org/)

Good. Using mingw-w64 (32 or 64 bit) is much better than using mingw32.

I'm using this tutorial  http://sourceforge.net/p/mingw-w64/wiki2/GeneralUsageInstructions/ under the headings "Installing the toolchain" and "Windows native"

1) I choose the "MinGW-builds" after reading under the headings "General Usage Instructions" and "Downloading the toolchain" from the same tutorial - it seemed like a good middle of the road choice.

2) I choose "32-bit target" under the MinGW-builds heading as it seems to most closely correspond to my current goal which take me to  http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0/32-bit/

3) I choose the "threads-win32" folder as it seems to most closely correspond to my current goal.

4) A note saying: "toolchains using DWARF for exception handling are also available and faster than SJLJ but you shouldn't use them unless you're aware of their bugs and limitations." found at: http://mingw-w64.sourceforge.net/download.php#win-builds

had me looking carefully between the choice of the "dwarf" or "sjlj" folders

I found an explanation here:

http://stackoverflow.com/questions/15670169/what-is-difference-between-sjlj-vs-dwarf-vs-seh

and so I choose "sjlj" as it seems to most closely correspond to my current goal 

5) From http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.0/32-bit/threads-win32/sjlj/ I downloaded my SJLJ error handling Windows 32bit version of Mingw-w64  dated:2013-04-20 and named:

"x32-4.8.0-release-win32-sjlj-rev2.7z"

6) Extracted using 7zip to c:\mingw32 I extract the file to a new folder called C:\mingw32 and actually have to Ctrl-A / Ctrl-C everything in the folder and copy to C:\mingw32 so that the executable I need is in C:\mingw32\bin I also delete the original folder c:\ming32\ming32 which I copied the file hierarchy from 7) Changed my path variable by adding: ;c:\mingw32\bin 4) From the Command Prompt: i686-w64-mingw32-gcc -v result:

All seemed well!

SO NOW WHAT?

As you can see I have documented what I have done as best I can as a new user to the environments and software technologies I am using so that there is not much of anything assumed and all described as specifically as possible and reasonable considering these are personal notes and not a tutorial for others (at least as of yet)

Best I can tell I need to download a QEMU tar.bz2 

Can I use one of these? http://wiki.qemu.org/Download

Either

* qemu-2.1.1.tar.bz2

* qemu-2.0.2.tar.bz2

or do I need to get another version from github - and if I do need another version from github can I use git with my current setup or so I need to add git to it?

Can I decompress these inside my windows file hierarchy in C:\ ?

Can I do it within the Command Prompt System now that I have my path assigned as described in PART 2 and PART 3 

Should I drop these into a new folder C:\qemu ? Is that a bad strategy?

That should be fine.

What would be the exact commands to expand these files considering the windows file hierarchy rather than a linux hierarchy or do I still have to get msys and run it in a linux hierarchy (prefer 1st option if possible)

You won't be successful with your preferred option (at least not without much work). Use msys.

Do I need to modify my path further for gcc to work from the Windows Command Prompt? What would I type exactly at the end of my current path?

How do I configure and make in this situation? (Considering the windows file hierarchy or again do I need to use msys? I prefer the first over the lattter option).

See above.

Am I already a root user?

On Windows? No. You are "paul" or whatever your Windows account is.

 

I'm hoping this can all be done from the Command Prompt instead of using msys but I'm open to anyone's instructions as long as they are current (Its September 14th 2014 when I wrote these notes.

Peter, I hope you might have further advice for this terrible noob. I'm going to also post what I have so far wherever I can figure out where to post it and get advice and email it to anyone who I think might give me an answer also. 

I'm also hoping to continue on this path rather than a whole other solution but I am willing to deviate again at the point of PART 3 if getting another 32 bit version of MinGW-W64? Actually I'm willing to follow any simple directions. I hope you see I have given it my own time and effort - It doesn't seem as though there are current documentation available for a newer native build on W32 right now so if someone can help me see it through to the end I will rewrite it yet futher and post to all relevant parties where current documentation aught to exist

Thank You,

PS. My binaries on http://qemu.weilnetz.de/ are cross compiled on Debian GNU Linux. I don't compile often on Windows because it is much slower.
