Well - when you consider that the compilation process is made up of three
things then you know what you can play with:
1. The sources.
2. The flags.
3. The tool chain.
Since the source didn't change it means that the change could either be in
the flags or in the tool chain. As far as I know ccache keeps the flags so
changing them will cause a recompilation. The only thing left the tool chain:
changing your compiter, assembler, linker, preprocessor or anything that
effects the way they work (for instance - if they are effected by environment
variables in some way or by the presense/lack of other programs that they may
run on an optional basis). This means that the only thing to watch out from
when using ccache is subtle changes in the tool chain. Stuff that has to do
with dynamic library search paths is also something to watch out from
(fiddling with /etc/ld.so.conf, LD_LIBRARY_PATH etc...).
Conclusion: unless you're fiddling with your tool chain ccache is safe. If
you are - then you probably know what you're doing and willing the eat your
own dogfood or clear the cache whenever you know you changed something that
will have an effect on generated objects.
On another note: if ccache would remove comments from sources when making MD5
signatures like my own dependecy management tool it would be even better
(adding comments is no reason for recompilation). Anyone know if ccache knows
how to do that or if this is planned ?

Mark
