Sheesh. I've got a multimillion line modern C++ protect that consists of a large number of dylibs and a few hundred delivered apps. A completely cache-free build is an only few minutes. Incremental and clean (cached) builds are seconds, or hundreds of milliseconds.
It sounds like you've got hundreds of millions of lines of code! (Maybe a billion!?) How do you manage that?
It’s a few million lines of c++ combined with content pipelines. Shader compilation is expensive and the tooling is horrible.
Our cached builds on CI are 20 minutes from submit to running on steam which is ok. We also build with MSVC so none of the normal ccache stuff works for us, which is super frustrating
Fuck. I write shader compilers.
Eh, you write them I (ab)use them.
I have 15 million lines of C++, and builds are several hours. We split into multi-repo (for other reasons) and that helps because compiling is memory bandwidth limited - on the CI system by we can split the different repos to different CI nodes.
