How to tell scons to exclude certain files from using the build cache

Scons provides an option to make use of a build cache, which is used to reduce build times by pulling up-to-date files from that cache. The enforcement of the cache seems to be global. For example, there are commands to force caching, disable caching, display the cache, etc. There does not seem to be a method within the CacheDir to exclude certain files, as there may be files that really should be recompiled.

Given this situation, what would some reasonable solutions be?

There is NoCache:

P = Program(...)
NoCache(P)

You are thinking about this the wrong way round. Instead of excluding an object from the cache, you tell the scons that the object that is being built doesn't go into a cache. The cache directory is set per environment, so you'll want to do something like this

noCacheEnv = env.Clone()
noCacheEnv.CacheDir(None)
noCacheEnv.Program('cantbecached.c')
