Speeding up C++ build times

• ClangBuildAnalyzer

  6 939 5.7 C++

  Clang build analysis tool using -ftime-trace

Coincidentally in the project I'm currently working I managed to reduce our compile times significantly (~35% faster) using ClangBuildAnalyzer [1]. The main two things that helped were precompiled headers and explicit template instantiations.

Unfortunately, the project still remains heavy because of our use of Eigen throughout the entire codebase. The analysis with Clang's "-ftime-trace" show that 75-80% of the compilation time is spent in the optimisation stage, but not really sure what do to about that.

• sccache

  71 5,385 9.4 Rust

  Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.

  

Use icecream or sccache. sccache supports distributed builds.
