Updated linux buildscripts in sticky at the top
Now it builds avr-gcc-4.2.2 , with binutils-2.1.8 and avr-libc-2.1.7.
Have a look here
And Jörg's announcement.
And the discussions thread
If you are not yet ready for avr-gcc-4.2.2....
I did also include an old 4.12/2.17 script , where the patchfiles are included. As they have been moved away from their old repository positions.
I have not made a testbuild , but expect it to work.
Just omit the get-patches step , they are allready in the archive.
I have not yet verified with Jörg , if this patch is not needed anymore , but it's not in the repository.
#gcc-patch-attribute_alias.diff <---- !! Removed in 4.2.2
So this might be an "Early version" 8) 8)
