主题: Re: [ccache] who is using ccache ?
Hiya,
I and most of my co-workers have been using ccache daily for years, It's hard to calculate the whole cost/time saving.
But my ccache stats on my work desktop are:
cache directory /home/inb/.ccache
cache hit (direct) 1868638
cache hit (preprocessed) 344752
cache miss 721058
called for link 384984
called for preprocessing 125100
multiple source files 369
compiler produced stdout 913
compile failed 209705
ccache internal error 3881
preprocessor error 33913
can't use precompiled header 468
couldn't find the compiler 20
cache file missing 6
bad compiler arguments 10054
unsupported source language 9665
autoconf compile/link 277992
unsupported compiler option 1209071
no input file 96619
files in cache 25989
cache size 2.4 Gbytes
max cache size 3.0 Gbytes
So, 2.3 million hits vs 720k misses since I last cleared the cache. It really does save lots of time for each hit

Hi all,
We are evaluating CCACHE/DISTCC to speed up our compiling and we are asked if it is valid & safe ?
Can someone provide samples/demo/articles that using CCACHE/DISTCC in there projects ?
Btw, better to have a show-case page on CCACHE home page.
Thanks,
Antony
