You can get statistics on the cache (its size, number of hits,
|
||||
misses, etc.) by running +make ccache-stats+.
|
||||
|
||||
The make target +ccache-options+ and the +CCACHE_OPTIONS+ variable
|
||||
provide more generic access to the ccache. For example
|
||||
|
||||
-----------------
|
||||
# set cache limit size
|
||||
make CCACHE_OPTIONS="--max-size=5G" ccache-options
|
||||
|
||||
# zero statistics counters
|
||||
make CCACHE_OPTIONS="--zero-stats" ccache-options
