AVR crosscompiler gcc instalation problem [Solved]

[Fallen_Angel]

Hi, I have a problem with installation AVR-crosscompilator on my Sabayon x86_64.
Installer rapports an problem with "USE='cxx nocxx' and USE='-cxx -nocxx'" while compiling gcc.
I'm tryed on gcc 4.5.3 and 4.6.2 - same resoluts

Step by step instructions
1. "emerge --unmerge cross-avr/gcc"
2. "emerge --unmerge cross-avr/avr-libc"
3. I'd wrote in "/etc/portage/package.keywords" these additional lines:

Code: Select all

# AVR Toolchain
=sys-devel/crossdev-20111011 ~amd64
cross-avr/binutils * -amd64 -~amd64
cross-avr/gcc * -amd64 -~amd64
cross-avr/avr-libc * -amd64 -~amd64
cross-avr/gdb * ~* -amd64 -~amd64
cross-avr/insight * ~* -amd64 -~amd64

4. emerge crossdev
5. addeded to "/etc/make.conf":

Code: Select all

PORTDIR_OVERLAY="/usr/local/portage $PORTDIR_OVERLAY"

6. "crossdev -t avr -s4"

Crossdev's Raport:

Any ideas?

In last step I had to put "USE="-nocxx" crossdev -t avr" instead of "crossdev -t avr" and everything woks fine.
