According to the manpage, ccache is a fast C/C++ compiler cache. It works with the gcc and clang compilers (or alike).
Reference
- ccache on GitHub
- ccache manual.

Install
On Debian / Ubuntu, ccache is available as a standard package:
sudo apt install ccache
To use ccache for compiling, just create a few symlinks. For instance, to use ccache with gcc and clang-3.6:
sudo ln -sf /usr/bin/ccache /usr/local/bin/gcc
sudo ln -sf /usr/bin/ccache /usr/local/bin/clang-3.6
This will work as long as the directory with symlinks comes before the path to the compiler (which is usually in /usr/bin).
Usage
- Collect ccache usage statistics:
ccache -s
- Set cache size:
ccache -M 2G
