The previous ccache.bbclass has the following problems:
- It uses host's ccache for native recipes, but this may not work on some
hosts, for example, it nerver works on my Ubuntu 14.04.4, there are always
build failures (m4-native failed at do_configure, and others will also be
failed if I disable CCACHE for m4-native)
- native/nativesdk/cross/crosssdk recipes use host's ccache, but target uses
ccache-native, this may confuse user.
- The target recipes may use both host's ccache and ccache-native, this may
cause unexpected problems and be hard to debug. This is because ccache-native is
in SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS, so ccache-native may not be present when
rebuild target recipes, and then it would use hosttools/ccache, but the
previous ccache files were generated by ccache-native.
- Target recipes can't use ccache when no ccache is installed on the host:
CCACHE = "${@bb.utils.which(d.getVar('PATH'), 'ccache') and 'ccache '}"
After refactored:
All types recipes (native, target and others) will use ccache-native except
ccache-native itself, host's cache won't be used any more. It is more
reliable now, which will work everywhere when ccache-native can be built.
And now we need use "CCACHE_DISABLE = '1'" to disable ccache for the recipe
rather than "CCACHE = ''" since we set CCACHE in anonymous function, and
d.getVar('CCACHE') works after "CCACHE ??=" which is set in bitbake.conf, so we
can't check whether CCACHE is set or not in anonymous function since it is
always set. Use CCACHE_DISABLE to disable it would be more clear.
