Introduction to Ccache
ccache is a compiler cache. It acts as a caching pre-processor to C/C++ compilers, using the -E compiler switch and a hash to detect when a compilation can be satisfied from cache. This often results in a 5 to 10 times speedup in common compilations.

Non-Multilib
Compile the package:
./configure --prefix=/usr && make
Install the package:
make install
Multilib
This package does not install any libraries so only one installation is needed.
Compile the package:
CC="gcc ${BUILD64}" ./configure --prefix=/usr && make
Install the package:
make install
Configuring
Using ccache
There are 2 ways to configure ccache. Either to prefix the compiler with ccache or to create alternate symlinks.
Method 1
To prefix the compiler with ccache you would need to set the following environment variables where appropriate:
CC="ccache gcc" CXX="ccache g++"
Or on multilib
CC="ccache gcc ${BUILD32}" CXX="ccache g++ ${BUILD32}"
Method 2
The second way would be to create some compatibility symlinks.
install -dv -m755 /opt/ccache/bin && ln -sfv ../../../usr/bin/ccache /opt/ccache/bin/gcc && ln -sfv ../../../usr/bin/ccache /opt/ccache/bin/cc && ln -sfv ../../../usr/bin/ccache /opt/ccache/bin/g++
Then put those links at the top of your path each time you login.
cat > /etc/profile.d/50-ccache.sh << "EOF" # Begin /etc/profile.d/50-ccache.sh export PATH="/opt/ccache/bin:${PATH}" export CCACHE_PATH="/usr/bin" # End /etc/profile.d/50-ccache.sh EOF
Using ccache with distcc
In addition to the above section. The CCACHE_PREFIX variable is a prefix tagged onto the command that ccache would run to compile code.
export CCACHE_PREFIX="distcc"
