First of all: If you are using our binary packages then you dont need it.
I dont use our binpackages and compile everything ... but ... I do my updates in the night (when I sleep) and dont care if it takes one hour or one hour and 20 minutes 
Maybe read our wiki article - here you will find typically useful reasons to use it: https://wiki.gentoo.org/wiki/Ccache
... and no, I dont use/need it.

That's about right. The average Gentoo user will not benefit from ccache. Further more, it introduces a new class of build-time failure scenarios that you are left debugging by yourself.
Not worth the trouble. |

I've had only a few failures related to that during my 4 year odyssey with my old hardware.
However with my current hardware it doesn't make much sense.

hi imbruxo,
you need it if you have in some packages the same binary to recompile. If one Package have some same dependencies and will compile the same binary file. Then ccache will push the answer sonner too it.
It is not easy to answer when its useful. But on gentoo its likely. because you have many packages that do not change. Since updates often change just few of sounds lines of code. However you have many libraries with chances and .. so on. If a sub library chance your upper code with that dependence will change too. But still ccache will boost everything which did not change. |
