I compiled a Toolchain including 4.7.0 (as of 2012-17-02) for Windows, including some fixes to known bugs of this version, like the LTO-Bug, the Relax Bug, The Multilib-tiny-stack Bug. There are probably other minor bugs but it works fine for me.
It is a standalone Toolchain, but only the core Components are included. All other Tools can be taken by WinAVR or Atmels Toolchain.
It includes:
- Binutils-2.22 (as of 2012-19-02)
- Avr-Libc-1.8.0
- AVR-Dude 5.11.1
- Languages: C, C++
- Support for ATMega and ATXMega Devices!!
As stated, you can use it as standalone version, but if you are missing some tools, install WinAVR first and then replace its files with those from my Package.
This is the Download Link, size is around 11 MB.
I hope you can profit from this! For my project, which is about 16kb, it improves the size 4,1% with -Os (Optimize for size) and 1,4% with -O2 compared to Atmels most recent Toolchain which is based on gcc 4.5.1
I would like to hear your results and please report any bugs, when found, here or directly to GCC Bugzilla.
Many greetings,
Stefan
Update 02/22: Added the missing .dll file to each directory. |

Thanks for the hard work, Stefan ! I'll let you know . I would've liked it to have USB_Xmega ( crt.o files ) support though, I know it wasn't under your control .  |

You can take a look at the appended file to see which devices are supported. Alot (or even all) ATXMegaxxxxU devices are supported and crt.o files are there. For exampe for the atxmega128a1u the file is crtx128a1u.o.
Or maybe i understand you wrong?
Edit: every device, that is mentioned in the appended file, is supported.
Please keep in mind that the xmega support is new and has not been tested by anyone besides me until now
Our tanks for this nice work belongs to the hard-working people from the avr-gcc department of GNU Compiler. Atmel itself has not released its sources from their xmega-supporting avr-gcc |

Yep this particular device isnt supported atm.
Let me talk to the developers and see what they can do!
Maybe you could take a look and provide a list of missing devices. |

| I tried the toolchain by overwriting it over the AS5.1 default toolchain folders (C:\Program Files (x86)\Atmel\AVR Studio 5.1\extensions\Atmel\AVRGCC\3.3.1.27\AVRToolchain) but it giving me this error when avr-gcc.exe starts and it can't compile. |

| Seems working in cygwin under Win7/64. I renamed the folder to C:/avr-gcc47 and added it to the beginning of the PATH, as you said winavr picks up the rest:
Code:
$ PATH=/cygdrive/c/avr-gcc47/bin:$PATH
Thanks!
Code:
$ avr-gcc --version
avr-gcc.exe (WinAVR 20100110) 4.3.3
$ avr-size -C --mcu=atmega1284p webserver6.avr-raven

$ avr-gcc --version

In INSTALL-DIR/avr/bin there should be a libiconv-2.dll.
BTW: I'd propose you could use path name with umlauts, ligatures and some chinese and khmer characters  |

Im sorry for this, its a mistake on my side.
I forgot to copy the file "libiconv-2.dll" in every directory where .exe files are. (For example where cc1.exe is)
The file is there though, you would just copy it from \AVR-Toolchain\bin to AVR-Toolchain\libexec\gcc\avr\4.7.0\
I will fix this of course, in the next release!

I compiled it under MinGW32 so didnt even know that it would work in cygwin. Nice, you got over 7% decrease in size!

Thats probably caused by the above mentioned missing libiconv-2.dll. Please tell me if this fixes your problem. Iam sorry for this! Was a little bit late when i packed the file together
Probably another method would be to add the \AVR-Toolchain\bin folder to your PATH variable, like dak664 did.
Edit: i updated the package in the first post to fix this issue.
Hope this helps!!

Why would you need to make copies - you just ensure the directory where it is located is on the PATH don't you? |

This would force you to use the by setting PATH. It's great to be able to use the tools without changing *anything* in the environment. |

WinAVr has always added \winavr\bin and \winavr\utils\bin to the PATH during installation - I don't think it's ever been considered a "problem".
(though it's true that if you have more than one make.exe or more than one cygwin1.dll it has caused some upset). |

Yeah WinAVR did that, but my Toolchain does not have a installer, so one would have to do it by hand.
OR
as i stated in first post, first install WinAVR and overwrite its files by those in my package.
But anyways, its fixed now. No need to edit PATH
Some people complained about WinAVR changig PATH, because it can interfere with other programs. |

| For anyone worried that changing PATH will break the existing tools, note PATH=foo:$PATH:bar affects only the current command window. So testing is harmless, and once you get it working you can add an alias to your .profile or .bash like alias usegcc47='PATH=foo:$PATH'. In Windows command windows it's set PATH=foo;% PATH% without the space after % |

I only read about it, for example look at first 3 posts at the bottom of this page. |
