I am looking at the document: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=3#doc_chap1 relating to ccache: In the document it states that the following environment variables should be set in /etc/make.conf CCACHE_SIZE="2G" CCACHE_DIR="/var/tmp/ccache" ccache -s when I emerge ccache, I get this * 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. If this is your first install of ccache, type * something like this to set a maximum cache size of 2GB: * # ccache -M 2G Which implies that setting the variables in /etc/make.conf is not needed. Setting CCACHE_DIR as recommended by the handbook creates errors when emerging. I think it might be a good idea for the handbook to be updated on this issue.
Still works here. man make.conf agrees that these variables are still okay.
