ccache not working?

ccache worked at first, but after some updates it doesn't seem to do anything any more.

when i run "ccache -s", the stats never change. i recently zeroed them out...but after re-emerging "gnome-system-monitor" as a test, the stats didn't show any change at all.

i added FEATURES="ccache" and "CCACHE_SIZE='2G'" both in make.conf and also followed the second installation instructions found in "man ccache" but neither of these seemed to fix it

if you need any info, just let me know and i'll post it up

thanks in advance! :D

*bump*
does anyone have any ideas?

noone knows? :(

i can give any extra information that you might need to help me fix this...

i'd like to get it to work so i can speed up any large updates (kdelibs, xorg, etc,..)

Try putting this:

Code:

---

PORTAGE_TMPDIR="/var/tmp/portage"

---

in your /etc/make.conf. It being portage, I don't think that everything works like it would normally with ccache. 8)

hmm...that didn't work either :?

i don't understand what went wrong. it worked early in my gentoo install, but once i started doing some updates it simply stopped doing anything. it was really unusual. oh well, i can live without it. i've installed enough things now that when i isntall something else or do an update it doesn't take too long, so i'm ok now 8)

thanks for the suggestion though! :D

Something must have changed recently because I came across the same problem. I fixed it by adding the CCACHE_DIR variable to make.conf.

It seems previously that CCACHE_DIR was implicitly set when ccache was added to FEATURES. The old cache directory for portage was /var/tmp/ccache. Unfortunately, ccache -s checks the default directory which is $HOME/.ccache. You can either set CCACHE_DIR as an environment variable in your startup scripts or use my approach which was to switch the portage ccache over to /root/.ccache.

Steps to solve:
1) add CCACHE_DIR="/root/.ccache" to /etc/make.conf
2) ccache -z -C [clear cache and zero stats]

Now try emerging something and testing with ccache -s.

This worked for me: Ccache Troubleshooting.

Good find. 8)

thanks rikster for that info!
