Hm, by looking at the sources, it seems that "ccache -M" and "ccache -F"
store cache size limits in the $CACHE_DIR/*/stats files. Which *kind of*
makes
sense because the stats are updated after every run.

This means having an environment variable for "cache size" does not make
sense. Yay. Sorry for the noise.

it was my understanding that ccache respected this.  didnt realize we
were hacking around the limitation in Gentoo by faking out the env var
-> cmdline opt.

You are perhaps referring to the variable that gentoo's portage [1]
accepts (and passes to ccache as an option).

Explicitly not what I was looking for, but thanks.

Hello,

Is the fact that the cache size limit is only configurable as a
commandline option intentional ? There seem to be environment
vars for virtually everything else but this.

I am asking because I am close to the 1GB limit and it would be
tedious to change some build scripts to use CC='ccache -M 2G'.
I would much rather keep my "gcc -> ccache" symlinks and
export a CCACHE_MAXSIZE in my login profile for instance.

I can send the patch if there is no easy way to do this already
(suggestions please ?).


Thanks for a very useful tool,
Bogdan
