[ptxdist] [PATCH 1/9 v2] [x86_64] Add x86_64 architecture strings.

[ptxdist] [PATCH 1/9 v2] [x86_64] Add x86_64 architecture strings.

[Remy Bohmer]

The ARCH_X86_64 architecture is added as subtype of ARCH_X86 since it
basically is the same architecture, and a mix of both architectures
will be required to allow multilib support in a later commit.

[ptxdist] [PATCH 3/9 v2] [x86_64, multilib] Remove all hardcoded paths from glibc.make

[Remy Bohmer]

These hardcoded paths do not work for a multilib environment where
libraries are typically installed in /lib64 for x86-64 instead of /lib
All correct paths can be found by interrogating the compiler toolchain
for the location of these files.

[ptxdist] [PATCH 4/9 v2] [x86_64, multilib] Make packages install their libraries at the right place

[Remy Bohmer]

While cross-compiling for x86_64 in a multilib configuration we need to
install the libraries conform the Filesystem Hierarchy Standard (FHS).
Summarised this will be for multilib:
* All libraries compiled for and used in 64-bit applications need to be
  installed in /lib64 or /usr/lib64.
* All libraries compiled for and used in 32-bit applications need to be
  installed in /lib or /usr/lib.
* All executables will still find its way in the regular /bin and /sbin
  paths.
* The Operating System itself and all its libraries should only be compiled
  in 64 bit mode. It should not be a mix between 32 and 64 bit libraries.
  32 bit support will only contain the libraries that are required by
  32-bit-applications to link against.

This is also conform what many distros derived from Redhat have in their
setup. Note that Debian based distros follow a somewhat different setup.

Note that we use the compiler toolchain to tell us at which paths we
need to install the libraries. This means that if you build for a x86_64
target _without_ multilib support the libraries will likely end up in the
classical /lib and /usr/lib directories, but that is completely steered
by the compiler toolchain configuration. (it follows the location where
the corresponding dynamic linker is expected to be installed)

So, this change makes ptxdist follow the sysroot of the compiler toolchain
more such that preliminary multilib support can be achieved. Preliminary
in the sense that only still one C-library is being installed.
In another changeset the support for a 2nd C-library installation will be
added. At least after this change (and a few subsequent ptxdist makefile
fixes) the /lib and /usr/lib area will only contain the contents that belong
there in multilib environment.

 v2: Fixed uClibc dynamic linker name resolving
     Reworked review remarks from Michael Olbrich:
     - Do not add fix paths to lib64, but get them from ptxd_get_lib_dir
     - Call ptxd_get_lib_dir from the shell script in the make files

[ptxdist] [PATCH 7/9 v2] [x86_64, multilib] Install Util-linux-ng libraries at the right place

[Remy Bohmer]

Notice that CROSS_AUTOCONF_USR contains --libdir=/usr/lib{,64} setting.
We want this library in /lib{,64} so we override this setting here
explicitly.

Re: [ptxdist] [PATCH 3/9 v2] [x86_64, multilib] Remove all hardcoded paths from glibc.make

Can't you use $(CROSS_LIB_DIR) here? I'd like to avoid larger changes to
install_copy_toolchain.sh. This depends a lot on the toolchain and is
rather difficult to test.

Re: [ptxdist] [PATCH 1/9 v2] [x86_64] Add x86_64 architecture strings.

Hi,

I've seen the whole series, but I'm rather busy, and this requires a bit
more thinking. So it may take a while before we get everything in.

Have you considered adding ARCH_X86_32 as well (in a switch)? I think some
if our current "ifdef ARCH_X86" are really for 32bit only, so an option
would probably be useful.

I've pushed a change, that cleans up calling gcc here and in
install_copy_toolchain.sh. Please rebase.

this is /lib or /lib64 etc. right? The way you use it later, you should
remove the leading '/'. Otherwise you'll get /usr//lib, and while that is
valid as path, some scripts may not match it correctly.

Forget this. That's your last line. I forgot to copy it, when I played with
the code.

Are you sure you want this? Of course it can be done, but it feels
what somewhat redundant if we add an explicit path here.
After rebase on top of your gcc changes it is just a 1 line change.
Well, let's do the following: I first do the rebase, and see from
there how it looks. Adding CROSS_LIB_DIR can be done version 4 of the
patchset ;-)

Kind regards,

Remy

I considered that but thought to look it like this: Assume the
platform is 32 bit, unless specified otherwise.
But maybe I have to look it at it more carefully. I drop it from the
series, and will repost this patch later. First, finalize the rest of
the series first.

Kind regards,

Keep it as it is for now. I think the paths are extra hints to find the
libs. But this really depends on the toolchain. I don't know if this is
still necessary.
Marc: this is your code, can you comment on that?

You also need to do something with the "x86 optimization" choice. None of
the current choices support 64bit but there is hardware that could run with
either.
