Actual Results:  
ccache -s always reports 2G max size

Just clarifying, but ccache -M 5GB does return correctly?
Also, what version...

[Comment 2 jieryn 2004-08-16 04:23:16 UTC]

% emerge -pv ccache
[ebuild   R   ] dev-util/ccache-2.3   0 kB 

% ccache -M 5G
Set cache size limit to 5242880k

% ccache -s
cache hit                              0
cache miss                             0
files in cache                         0
cache size                             0 Kbytes
max cache size                       2.0 Gbytes

You may have to add it to your env or your make.conf.  I believe portage resets it to 2G unless it's told otherwise.

Try adding this line to /etc/make.conf:
CCACHE_SIZE="5G"

[Comment 4 jieryn 2004-10-02 07:55:50 UTC]

did you even try this yourself?  i have tried CCACHE_SIZE="5G" and CCACHE_SIZE="5GB" in make.conf, neither will report properly with ccache -s

[Comment 5 jieryn 2004-10-02 07:58:51 UTC]

i also find it interesting that emerge --info does not list CCACHE_SIZE as i think it should..  perhaps this is configuration option is not being picked up at all and therefore ccache -s is always falling back to the default, 2G ..?

[Comment 6 Brian Harring (RETIRED) 2005-03-09 01:51:01 UTC]

Try this with ccache v2.4 please.

[Comment 7 Marius Mauch (RETIRED) 2005-03-09 04:33:15 UTC]

how is this even a portage issue?

[Comment 8 jieryn 2005-03-09 17:13:24 UTC]

i attempted this with the v2.4 release and it works for me.
