This ensures that the cache directory (and all of its ancestor directories) exist. This is a nice thing to do because, if the parent of the cache directory doesn't exist, then ccache will complain that it cannot create the cache directory, causing the build to fail.

# Force ccache to use its internal zlib. The problem is that without
|
|
# this, ccache would link against the zlib of the build system, but we
|
|
# might build and install a different version of zlib in $(O)/host
|
|
# afterwards, which ccache will pick up. This might break if there is
|
|
# a version mismatch. A solution would be to add host-zlib has a
|
|
# dependency of ccache, but it would require tuning the zlib .mk file
|
|
# to use HOSTCC_NOCCACHE as the compiler. Instead, we take the easy
|
|
# path: tell ccache to use its internal copy of zlib, so that ccache
|
|
# has zero dependency besides the C library.

# BR_CACHE_DIR is exported by Makefile based on config option

# - ccache shouldn't use the compiler binary mtime to detect a change in
|
|
# the compiler, because in the context of Buildroot, that completely
|
|
# defeats the purpose of ccache. Of course, that leaves the user
|
|
# responsible for purging its cache when the compiler changes.
