Re: [gentoo-user] ccache: unsupported compiler option
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 link14836
multiple source files 87
compile failed 2
preprocessor error 1732
bad compiler arguments 1
not a C/C++ file4774
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}
Have you tried http://gentoo-wiki.com/Ccache?
