I'm trying to find out why ccache won't cache anything. Building and maintaining for three months an entire system got me all of 5 cache hits. What can I do to encourace more cache usage? One of the methods I'm investigating is to determine and eliminate CFLAGS arguments that may cause 'unsupported compiler option' to be incremented. Is there anything else I can try?# ccache -s cache directory /var/tmp/ccache cache hit 5 cache miss 153 called for link 14836 multiple source files 87 compile failed 2 preprocessor error 1732 bad compiler arguments 1 not a C/C++ file 4774 autoconf compile/link 28079 unsupported compiler option 2569 no input file 8965 files in cache 306 cache size 4.3 Mbytes max cache size 2.5 Gbytes # grep CFLAGS /etc/make.conf CFLAGS="-march=athlon64 -mtune=athlon64 -m64 -O3 -fmessage-length=0 -pipe" CXXFLAGS="${CFLAGS}"
