I'm trying to use ccache to speed up (re)compile time, but I can't get it to work with ebuild.
I set up symlinks for gcc, cc, c++ and g++ under /sbin, all pointing to /usr/bin/ccache. The
actual compilers are all under /usr/bin too. I put /sbin before /usr/bin in my PATH variable, so a
call to gcc gets /sbin/gcc, which is a symlink to /usr/bin/ccache, which in turn calls
/usr/bin/gcc automatically.
For test purposes, I'm using the ebuild file bzip2-1.0.1-r4.ebuild.
Running
# ccache -s
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild clean
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild compile
# ccache -s
I notice that ccache is not used.
But running
# ccache -s
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild clean
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild unpack
# cd /var/tmp/portage/bzip2-1.0.1-r4/work/bzip2-1.0.1
# make clean
# make all
# ccache -s
I notice that ccache _is_ used. Even if I use /usr/lib/portage/bin/emake instead of make.
I also noticed that there is an "export PATH=..." command in /usr/lib/portage/bin/ebuild.sh, but
even there /sbin is before /usr/bin. Just to make sure, I appended the command "which gcc" to the
end of the src_compile() function in bzip2-1.0.1-r4.ebuild.
Now, running
# ccache -s
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild clean
# ebuild /usr/portage/sys-apps/bzip2/bzip2-1.0.1-r4.ebuild compile
# ccache -s
again, I see that the output of the "which gcc" I added is indeed "/sbin/gcc", but still ccache is
not used.
I don't know what to do, any more... I'd appreciate any input on this.

CCACHEDIR is not set, so it should use the default $HOME/.ccache (/root/.ccache in this case).
Could it be that sandbox id denying write access to that dir?

Thanks!
I've put together a mini-setup-guide for ccache under Gentoo:

Hi
A couple of days ago it was recommended on this list to use ccache. I
have now tried ccache, and I think it breaks some builds horrible. As of
now I have tried to build mozilla-1.3-r2, and jack-cvs. Those packages
fail with an error that the linker parser cannot understand the format
of one of the object files. I think it would be a very good idea not
have the ccache flag enabled by default it simply breaks normally
working ebuilds. I think that it should be something you can set in your
use flags if you know what you are doing.
Comments welcome. It could be me just to stupid to use ccache ;-)
Regards
Hasse

It is a setting you can put in your FEATURES in /etc/make.conf
I've never had any problems with ccache, in fact I built mozilla-1.3 the
other day with it (and distcc) and my ccache is shared via nfs between 3
machines. I probably shouldn't share the cache, but it hasn't hurt yet!

Have tried to reemerge some of the packages, so the ccache actually gets
used when emerging mozilla-1.3?

Even if it's on by default ccache is not installed automatically (at
least in my case) and I had to emerge it explicitly.

I've been using ccache for over a year and have remerged mozilla-1.3
about 3 or 4 times and never had a problem (and yes I'm sure that it was
using the cache as it took about 20 mins the 2nd time)
