Hi, I have just pushed the ccache for MSVC to dev-tools: http://cgit.freedesktop.org/libreoffice/contrib/dev-tools/tree/ccache-msvc From the README.txt it should be pretty obvious what to do to make it work for you on Windows, so hope it will help you :-) I have no measurements how much does it speed up the build (if at all); I think at some stage I got to a number like >20% speedup, but who knows, my build takes something like 20 hours, so I am not patient enough to really test it ;-) More info: http://artax.karlin.mff.cuni.cz/~kendy/blog/archives/permalinks/2011-04-15T17_01_41.html http://artax.karlin.mff.cuni.cz/~kendy/blog/archives/permalinks/2007-07-02T18_26_56.html Enjoy, Kendy
