[ptxdist] [PATCH 0/7] OSELAS.Toolchain: add x86_64-unknown-linux-gnu glibc toolchain

[Andreas Bießmann]

This series has an generic part to build a cross toolchain where build ==
host == target (add fake build type to HOST_CROSS_AUTOCONF) which is useful
for all toolchains.

The rest of this series is a 'pure64' x86_64-unknown-linux-gnu glibc
toolchain. The pure64 means that glibc's slibdir is set to /lib instead of
/lib64. Since we build for embedded systems it is not necessary to have
multilib-able toolchains. Additionally the '/lib - only' approach fits best to
current ptxdist way of building the rootfs.

Andreas Bießmann (7):
  add fake build type to HOST_CROSS_AUTOCONF
  architecture.in: add x86_64 arch
  add x86_64-unknown-linux-gnu configuration
  fixup_ptxconfigs.sh: add x86_64 target
  glibc-headers: prepare for x86_64 build
  gcc-4.6.2: add pure64 patch for x86_64
  glibc: force slibdir to /lib

[ptxdist] [PATCH 1/7] add fake build type to HOST_CROSS_AUTOCONF

[Andreas Bießmann]

If we build a cross toolchain where build == host == target the resulting
tools lack the host-tripplet before the tool name.
This patch introduce a '--build' autoconf switch with guessed (and modified)
build host tripplet from ptxdist to supress the generic autoconf guessing
mechanism in respective tools.

Re: [ptxdist] [PATCH 0/7] OSELAS.Toolchain: add x86_64-unknown-linux-gnu glibc toolchain

[Klaus.Hachmeister]

Is it possible to have a toolchain

host=   x86_32
target= x86_64

?

The gcc should run on 32 bit system, but should generate 64 bit code. ("crosscompiler")
The libraries for the target should be 64 bit. ('pure64' x86_64-unknown-linux-gnu glibc)
/lib only instead of /lib and/or /lib64 on the target would be fine.


Mit freundlichen Gruessen / Best regards

Re: [ptxdist] [PATCH 0/7] OSELAS.Toolchain: add x86_64-unknown-linux-gnu glibc toolchain

Dear Klaus Hachmeister,

current OSELAS.Toolchain require build = host (yes canadian builds are
covered by rules/toolchain.make, but no toolchain utilizes it),
therefore should be possible (and is a normal use-case) to have a build
= host = x86_32 to build a target = x86_64 cross toolchain.

But beware, these patches are the first shot for x86_64 target. The
resulting toolchain needs some testing and may fail in some cases,
though it can build a minimalistic rootfs.

best regards

I've applied the whole series. I had to add --host=$(GNU_HOST) as well, but
that shouldn't break anything for you. Please test.
