>=C2=A0 =C2=A0 =C2=A0 Could you give me in detail ?

you probably want to create a new profile dir:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 profiles/arch/powerpc/ppc64/little-endian/
then add a make.defaults file with the right CHOST defaults.=C2=A0 as we fi= nd
packages that have problems on little endian, that provides you a safe
space to mask features too.

then create a new target for linux users:
=C2=A0 =C2=A0 =C2=A0 =C2=A0 profiles/default/linux/powerpc/ppc64/13.0/64bit= -userland/little-endian/
that'll inherit the arch/powerpc/ppc64/little-endian parent

you mean my bootstrap-portage script ?

do you have hardware ?=C2=A0 then it's simply a matter of booting Gento= o in it and

YES. We have K= VM virtual machine of ppc64le.=C2=A0 Can we booting/filing/fixing by KVM ?<= /div>
