I can fix it myself if you let me (and check/fix your maintained packages if you want): To use ccache with **non-Portage** C compiling, add /usr/lib64/ccache/bin to the beginning of your path, before /usr/bin. Portage 2.0.46-r11+ will automatically take advantage of ccache with no additional steps. -> Could use readme.gentoo.eclass to show it first time and have it in README.gentoo file under /usr/share/doc If this is your first install of ccache, type something like this to set a maximum cache size of 2GB: # ccache -M 2G -> This should be shown only first time (as the message says) If you are upgrading from an older version than 3.x you should clear all of your caches like so: # CCACHE_DIR='/var/tmp/ccache' ccache -C -> This should be shown when updating from that older versions Thanks Reproducible: Always
should be all set now in the tree; thanks for the report! Commit message: Only show ccache messages on first emerge http://sources.gentoo.org/dev-util/ccache/ccache-3.1.9.ebuild?r1=1.13&r2=1.14
