ccache 0.0kB cache size

My setup:

SlackWare current 5.4.11
ccache 3.7.6

cache -s output:

Code:

cache directory                     /home/uninstance/.ccache
primary config                      /home/uninstance/.ccache/ccache.conf
secondary config      (readonly)    /etc/ccache.conf
stats updated                       Wed Jan  8 09:45:19 2020
cache hit (direct)                     0
cache hit (preprocessed)               0
cache miss                             0
cache hit rate                      0.00 %
called for link                        7
couldn't find the compiler             1
no input file                         29
cleanups performed                     0
files in cache                         0
cache size                           0.0 kB
max cache size                      10.0 GB

Problem: As you can see symlinks work and max cache size is appropriate but actual cache size is 0.

Not sure how ccache works in Slackware but in FreeBSD, you have to tell whatever is building the software that ccache is present and where the cache is. Is there another configuration (make.conf?) you have to set?

It is not system dependent. There are two ways to use ccache, you either prepend compiler commands with ccache or create symlinks.

Understood, what I meant was that on FreeBSD, I have to tell the builder (in my case poudrier) that ccache is present and where the cache is. I have no idea how it is done in Linux.

This is a building system that prepends compiler commands that you use with ccache if you ask it to. Or it you can create symlinks so that you do not have to tell your build system to use ccache.
