Hi Guys,

Any comment on this?

Regards,

# Response to patchwork cleanup of week #1

This patch provides an easy way to operate on buildroot ccache such as
changing the cache limit or showing statistics.

Without it, users would have to explicitly specify both the environment variable
and the path of patched ccache, for example:

  BUILDROOT_CACHE_DIR=~/.buildroot-ccache/ $PWD/host/usr/bin/ccache -s
.
Thanks.

Roy

  You should add this text to the documentation in
docs/manual/ccache-support.txt

  Missing Signed-off-by line.

  Otherwise looks good to me.

Dear Tzu-Jung Lee,

Well, in the case of just passing "-s", we already have the
ccache-stats target.

But I agree that for all other options, adding another
ccache-<something> target would be impractical, so probably your
proposal of CCACHE_OPTIONS makes sense.

Can you respin your patch on top of the latest master, and add an
update to the manual (we already have a section about ccache support,
see http://buildroot.org/downloads/manual/manual.html#ccache).

Thanks!

Thomas
