Using ccache with Xcode 4

Question

Is there any way to use ccache with Xcode 4, to improve C++ build time?

Using environment variables I've set CC and CXX to ccache, but the build fails since ccache does not recognise some of the parameters that Xcode 4 outputs.

Answer 1

Ccache has Clang support from version 3.2 and newer.
