The name of the sysroot directory is arbitrary, but as ct-ng uses sys-root,
let's use that as well for consistency.

As Thomas said on IRC, I would suggest to revert this. Is there anything
in BR that depends on the sysroot being named 'sysroot' or 'sys-root' at all,
or was that just an eye-candy change? (genuine question)

I will push the change in crosstool-NG that makes this configurable, and
the default is now 'sysroot', instead of the old hard-coded 'sys-root'.

Then, it will be a matter of taste what to set it to, with BR forcing it
to whatever suits (I believe just 'sysroot').

Also, note that not all toolchains set this to any of 'sysroot' or 'sys-root'.
For example, the CodeSourcery toolchains set this to 'libc' for the main
sysroot, and to libc/${variant} for each supported variant's sysroot.

Regards,
Yann E. MORIN.

Just for the record, my preference for "sysroot" instead of "sys-root"
is because all sysroot-related options in gcc use the "sysroot"
spelling and not "sys-root" :

 -print-sysroot
 -print-sysroot-headers-suffix
 --sysroot

And all gcc documentation refers to it as the "sysroot" :

`-print-sysroot'
     Print the target sysroot directory that will be used during
     compilation.  This is the target sysroot specified either at
     configure time or using the `--sysroot' option, possibly with an
     extra suffix that depends on compilation options.  If no target
     sysroot is specified, the option prints nothing.

Regards,

Thomas

No, as mentioned - The name is arbitrary, but as the ct-ng version we're
currently using hardcodes it as sys-root, then we either need to use
sys-root or add symlinks if we want ct-ng to install directly into
HOST_DIR/usr to get BR's and ct-ng's idea of $tuple/sys-root to match.

Ok, good.

Yeah. Until very recently noone really cared as STAGING_DIR used to be
directly in output/.

Yes, but that's OK. This change was just to get the ct-ng toolchain to
behave more similar to the internal one.

Yes, agreed. That's the reason I also changed the default in crosstool-NG
to 'sysroot', to match the literature.

The 'sys-root' name comes from the original crosstool:
  http://code.google.com/p/crosstool/source/browse/trunk/src/crosstool.sh#320

I saw no reason to change it at the time, although I hae no strong opinion
about it (so I renamed).

Yann E. MORIN.
