[gentoo-dev] ccache and sandbox

[gentoo-dev] ccache and sandbox

[John White]

I heard an interesting question on irc just now.  Does anyone have
ccache on a system actually working to accellerate repeat compiles?

For a ccache overview: http://ccache.samba.org/

Short version, ccache speeds up repeat compiles by caching compiler
i/o.

However, because of the sandbox, ccache info results in a sandbox
violation.  The user patched sandbox to allow writes to /var/cache/ccache
but I'm wondering if there is supposed to be a better way.

  I've got another solution. In fact, the standard sanbox allows full
read / write acces in /tmp directory. So, I just set CCACHE_DIR to
'/tmp/root/ccache' and CC to 'ccache gcc' before calling emerge.

  It works well this way and it doesn't need to modify the sandbox !

[gentoo-dev] sandbox howto?

[Sean P. Kane]

Where is the documentation for sandbox or at least a detailed
description of how it works, settings, etc?

Thanks,
Sean
