  272. During the build, many -I include directives are given with an
  273. absolute path. These absolute paths end up in the hashes that
  274. are computed by ccache. Therefore, when you build from a
  275. different directory, the hash will be different and the cached
  276. object will not be used.
  277. To improve cache performance, set this option to y. This
  278. allows ccache to rewrite absolute paths within the output
  279. directory into relative paths. Note that only paths within the
  280. output directory will be rewritten; therefore, if you change
  281. BR2_HOST_DIR to point outside the output directory and
  282. subsequently move it to a different location, this will lead
  283. to cache misses.
  284. This option has as a result that the debug information in the
  285. object files also has only relative paths. Therefore, make
  286. sure you cd to the build directory before starting gdb. See
