I use distcc, tho not ccache. I started this way, the i decided it was too 
problematic. I found the following a lot better:

First, a wrapper round make:

[mike@henley mike]$ cat /usr/local/bin/mmake3
#!/bin/sh

export DISTCC_HOSTS='localhost legacy archibold'
export PATH=/usr/local/distcc:$PATH 
make

[mike@henley mike]$

I've also got a mmake2 for when "legacy" is running XP :(( Then

[mike@henley mike]$ cat /usr/local/distcc/gcc
#!/bin/sh
echo `date`: distcc /usr/bin/gcc $* >> /tmp/distcc.log
exec distcc /usr/bin/gcc $*
[mike@henley mike]$

(and similarly for g++). The logging is just so I could convince myself that 
it was doing the right thing.


Then, if i *know* may change will only recompile one file, then i just do 
make, and I know the build will run on localhost, which is the fastest 
machine (and there are no distcc overheads). OTOH, for big changes I use the 
command "mmake3" (or "mmake2" :)

One extra advantage of this is, you can set it up without root access, it., 
just put the scripts in a directory of your own and adjust the paths to 
match.

I guess the same could work to use ccache as well.

The box said "Install Windows 98 or better".
So I installed Linux.
