When I tried to use task prebuilt to accelerate my build, it looks that sstate cache is not utilized although I didn't change anything between the two builds. Further check gave me different checksums, and then when I used bitbake-diffsigs below errors occur: bitbake-diffsigs /media/disk/sstate-cache/sstate-zlib-native-i686-linux-1.2.5-r0-i686-1-6252843ebd096ed45f126dec4125f9d6_populate-sysroot.tgz /media/disk/sstate-cache/sstate-zlib-native-i686-linux-1.2.5-r0-i686-1-4c1abb703ea0b6f458c8160ec489178d_populate-sysroot.tgz Traceback (most recent call last): File "/home/poky/tasks/poky/scripts/..//bitbake//bin/bitbake-diffsigs", line 10, in <module> bb.siggen.compare_sigfiles(sys.argv[1], sys.argv[2]) File "/home/poky/tasks/poky/scripts/..//bitbake/lib/bb/siggen.py", line 171, in compare_sigfiles a_data = p1.load() cPickle.UnpicklingError: invalid load key, '^_'. 10815 1 kevin.tian 2010-10-27 22:50:25 +0000 sorry a false alarm.
