Their reddit comments are not consistent with my experience using distcc. I can attest it is indeed a distributed ccache and works quite well. For a while I was even using distcc with a GCC cross compiler on Windows nodes to speed up my Linux app builds.

If there's a sccache maintainer reading this thread please consider explaining the advantages of using sccache over distcc in the README.

The distcc readme says nothing of the sort? It seems to specify that it shares header files and compiles cpp files (which are all presumably sent back to the source as object files, which links them together)

It seems to work with ccache, but if you're spinning up fresh instances all the time ccache will need to be synchronized somehow, and it doesn't seem to drive that (whereas sccache seems to do so)

distcc is not a cache. It doesn't keep the output of the compiler around after it builds things. It (only) distributes running the compiler around (and to do that handles some details of preprocessing, in certain modes) and then gets the output back to the requester of the compilation task.

At that point, the requester could cache that output, should they want to.
