Description Billy Pollifrone 2005-08-12 05:44:57 UTC 
Following the instructions outlined in Working with Gentoo, Portage Features,
Caching compilations (see URL) does not fully enable caching. The CCACHE_DIR
environment variable being set to "/var/tmp/ccache/" cures this problem.

Reproducible: Always
Steps to Reproduce:
1. Follow ccache install instructions
2. emerge something
3. Check ccache -s shows no usage
4. echo CCACHE_DIR="/var/tmp/ccache" >> /etc/env.d/99local
5. env-update
6. emerge something
7. ccache -s now shows usage

Uhm, no... it does cache, your command is incorrect. It should be
'CCACHE_DIR=/var/tmp/ccache ccache -s'

No environment variable is however needed for the caching to work during emerge.
