C++

C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...

Compiler

A compiler is a computer program that transforms source code written in a programming language into another computer language...

 so that the next time, the same compilation can be avoided and the results can be taken from the cache. This can greatly speed up recompiling time. The detection is done by hashing

Fingerprint (computing)

In computer science, a fingerprinting algorithm is a procedure that maps an arbitrarily large data item to a much shorter bit string, its fingerprint, that uniquely identifies the original data for all practical purposes just as human fingerprints uniquely identify people for practical purposes...

 different kinds of information that should be unique for the compilation and then using the hash sum to identify the cached output. Ccache is licensed under the GNU General Public License
