Now that my old AthlonXP mobo has been replaced by an AMD 64 X2 mobo,
it's time for upgrading CHOST :->
According to http://www.gentoo.org/doc/en/change-chost.xml after a
couple of changes to /etc/make.conf, i.e.
from:
USE="x86 ..."
CHOST="i686-pc-linux-gnu"
CFLAGS="-O2 -march=athlon-xp -pipe"
to:
USE="amd64 ..."
CHOST="amd64-pc-linux-gnu"
CFLAGS="-O2 -march=x86-64 -pipe"
The next step is:
emerge -av1 binutils gcc glibc
The emerge of binutils works fine. However the emerge of gcc fails
with:
In file included from .../gcc/unwind-dw2.c:257:
gcc/config/i386/linux-unwind.h: In function
'x86_64_fallback_frame_state':
gcc/config/i386/linux-unwind.h:63:
error: 'struct sigcontext' has no member named 'rsp'
A quick search of BGO didn't show anything relevant.
Any suggestions???
Thanks.
You're getting that _specific_ error because there is no register
'RSP' (the 64-bit stack pointer in the AMD64 world) in the 32-bit x86
world. (You have a 32-bit stack pointer 'esp' instead.)
