Comment 3 Thomas Petazzoni 2015-10-13 08:06:20 UTC 
Thanks for your bug report.

However, your patch is incorrect: we don't want to use /usr/bin/ccache, but the ccache that Buildroot builds in $(HOST_DIR). So the current code is perfectly correct.

HOST_DIR is defined in the main Makefile:

HOST_DIR := $(BASE_DIR)/host

If you have an issue with the ccache support, could you instead report 1/ the Buildroot configuration you've used and 2/ the last ~100 lines of build output. This way we can see if there is indeed something broken in Buildroot or some other issue.
