It stores the +object files resulting from each compilation process, and is able to +skip future compilation of the same source file (with same compiler +and same arguments) by using the pre-existing object files. When doing +almost identical builds from scratch a number of times, it can nicely +speed up the build process. + ++ccache+ support is integrated in Buildroot. You just have to enable ++Enable compiler cache+ in +Build options+. This will automatically +build +ccache+ and use it for every host and target compilation. + +The cache is located in +$HOME/.buildroot-ccache+. It is stored +outside of Buildroot output directory so that it can be shared by +separate Buildroot builds. If you want to get rid of the cache, simply +remove this directory. + +You can get statistics on the cache (its size, number of hits, +misses, etc.) by running +make ccache-stats+. |
