There is a later avr-libc as part of the AVR Studio 5 download. Be warned that the download is 0.5GB and has to unpack about 2GB of data for you simply to access the 20MB (or whatever it is) of avr-libc

You clearly haven't been reading the AS5 forum here if you believe that - it's FULL of bugs and missing functionality. In fact I'd call it an alpha rather than a beta as there's still parts left to be implemented.

I am not interested much on AS5 only i require WINAVR with latest avr-libc so i thought i can use the new AS5 which is having GCC with latest avr-libc.
for Building Winavr with latest avr-libc i have to learn lot of other tools. there is any other source of Winavr with new avr-libc available. I am using now WinAVR-20100110.

The latest release on the official avr-libc site is 1.7.1 released on 2011-02-16.

I don't know whether that contains all the patches that Atmel has applied to "the toolchain", though.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

It just sunk in that you want binaries (right?). Sorry. No binaries there.

So now we're back to the link that atomicdog posted above, where the steps to build on Windows are described. Not something I've gone through myself, so can't contribute much more than what the steps in that description gives..

Surely you just download AS5 and take the Avr-gcc and avr-libc from it?

Finaly I started to download the AS5 :evil:.
my internet speed 10KB/sec-20KB/sec so it will take at least 5hrs to 10hrs.

I have a folder "C:\Program Files\Atmel\AVR Studio 5.0\extensions\Application\AVR Toolchain\avr" that seems to correspond to the folder "C:\WinAVR-20100110\avr".

Verify it yourself when you have AS5 downloaded.

Don't forget to back up WinAVR (and/or make sure you have a valid installer for 20100110) before you start copying stuff around!

Why would you need to copy stuff? In your PATH just replace:

x:\WinAVR20100110\bin;x:\WinAVR20100110\utils\bin

with

x:\Program Files\Atmel\AVR Studio 5.0\extensions\Application\AVR Toolchain\bin

and now when avr-gcc is run it'll be the new one, not the old one. avr-gcc has built in (relative) paths to where it will locate everything else.

(one thing this highlights is that AS5 does not have the utils - major shame!!)

AVR Toolchain puts the coreutils programs in the bin folder instead of a separate one like WinAVR.

Thank you all
finally my WinAVR 20100110 updated successfully.
i copied all the file from C:\Program Files\Atmel\AVR Studio 5.0\extensions\Application\AVR Toolchain
to C:\WinAVR-20100110.
Note:i am not using AVRDUDE,SimulAVR..etc.so no idea these tools will work or not.

Result orginal WinAVR 20100110
