[Buildroot] Building x86_64 failes

[Goetz Bock]

Dear list,

after I've successfully build buildroot for i586 on my
amd64/debian/sarge box, I wanted to build the same rootfs for amd64.

So I copied the existing buildroot, removed build_i586 and
toolchain_build_i586, ran make clean and make menuconfig to
reconfigureit for x86_64.

But building the toolchain failes with:

/build/buildroot.amd64/toolchain_build_x86_64/gcc-4.1.1/gcc/config/i386/linux-unwind.h:
In function 'x86_fallback_frame_state':
/build/buildroot.amd64/toolchain_build_x86_64/gcc-4.1.1/gcc/config/i386/linux-unwind.h:152:
error: 'struct sigcontext' has no member named 'esp'
.
. [ more missing e?? members ]
.

It does not matter what version of binutils/gcc I use, it's always the
same error.
(I've tried binutuils: 2.16.1, 2.17, 2.17.50.0.7, 2.17.50.0.9 and gcc
4.0.3, 4.1.1, 4.2)

The i386 realy irritates me, and I've no idea where it comes from.

Any pionters?

Can you check that uClibc has the correct arch set?

The config/i386 is ok

What kernel-headers do you use?

hm. Could it be that you try to compile a 32bit x86-64 compiler? For the
64bit, there is definately no (resp. shouldn't be a) esp.

The toolchain_build_x86_64/uClibc-0.9.28/.config lists:
TARGET_x86_64=y
ARCH_SUPPORTS_LITTLE_ENDIAN=y
TARGET_ARCH="x86_64"
ARCH_LITTLE_ENDIAN=y
KERNEL_SOURCE="/build/buildroot.amd64/toolchain_build_x86_64/linux"

In the KERNEL_SOURCE dir include/asm is linked to asm-x86_64

I'm using the 2.6.12.0 headers, as my kernel will be 2.6.18 from Etch

That's at last not what I intend. I want to build a small rescueue
system to work with Debian Etch kernels.

I don't use these headers, so can't help you there. The 2.6.19.2 worked
for me for building an x86_64 rootfs, fyi.

HTH,
