No, ccache does not support distributed compilation, unless you use a cache directory shared over the network (e.g. using NFS), which I assume you could use for your compiler cache as well.

Yes, to the point that it will be an almost completely different program. -- Joel ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache

What problems do you see with your own compiler cache that makes you consider
using ccache instead?
Does your compiler behave similar to GCC, for instance using "-c" for
compilation, "-E" for generating preprocessed output similar to that of GCC,
"-x" for selecting source language, etc? If not, my guess is that it's not
really feasible.
There is no documentation or examples for adding new compiler support to
ccache, mainly because ccache in a sense only supports one ("GCC and compilers
that behave similar enough").
