Similar to what native and staging is doing since: https://git.openembedded.org/openembedded-core/commit/meta/classes/native.bbclass?id=d6c7b9f4f0e61fa6546d3644e27abe3e96f597e2 https://git.openembedded.org/openembedded-core/commit/meta/classes/staging.bbclass?id=1cf62882bbac543960e4815d117ffce0e53bda07 Cross task outputs can call native dependencies and even when cross recipe output doesn't change it might produce different results when the called native dependency is changed, e.g. clang-cross-${TARGET_ARCH} contains symlink to clang binary from clang-native, but when clang-native outhash is changed, clang-cross-${TARGET_ARCH} will still be considered equivalent and target recipes aren't rebuilt with new clang binary, see work around in https://github.com/kraj/meta-clang/pull/1140 to make target recipes to depend directly not only on clang-cross-${TARGET_ARCH} but clang-native as well. I have added a small testcase in meta-selftest which demostrates this issue. Not included in this change, but will send it if useful. openembedded-core $ ls -1 meta-selftest/recipes-devtools/hashequiv-test/ print-datetime-link-cross.bb print-datetime-link-native.bb print-datetime-native.bb print-datetime-usecross.bb print-datetime-usenative.bb print-datetime-native provides script which prints defined PRINT_DATETIME variable. print-datetime-link-native and print-datetime-link-cross both provide a symlink to the script from print-datetime-native. print-datetime-usenative and print-datetime-usecross are target recipes using the native and cross versions of print-datetime-link-* recipe. # clean build all is rebuilt: $ bitbake -k print-datetime-usenative print-datetime-usecross WARNING: print-datetime-native-1.0-r0 do_install: print-datetime-native current DATETIME in script is 2025-11-13_20_05 WARNING: print-datetime-link-native-1.0-r0 do_install: print-datetime-link-native current DATETIME in symlink is 2025-11-13_20_05 WARNING: print-datetime-link-cross-x86_64-1.0-r0 do_install: print-datetime-link-cross-x86_64 current DATETIME in symlink is 2025-11-13_20_05 WARNING: print-datetime-usenative-1.0-r0 do_install: print-datetime-usenative current DATETIME from print-datetime-link is 2025-11-13_20_05 WARNING: print-datetime-usecross-1.0-r0 do_install: print-datetime-usecross current DATETIME from print-datetime-link is 2025-11-13_20_05 # keep sstate-cache and hashserv.db: # print-datetime-usenative is correctly rebuilt, because print-datetime-link-native has different hash (because print-datetime-native hash changed) # print-datetime-usecross wasn't rebuilt, because print-datetime-link-cross-x86_64 doesn't include the changed hash of print-datetime-native $ bitbake -k print-datetime-usenative print-datetime-usecross WARNING: print-datetime-native-1.0-r0 do_install: print-datetime-native current DATETIME in script is 2025-11-13_20_07 WARNING: print-datetime-link-native-1.0-r0 do_install: print-datetime-link-native current DATETIME in symlink is 2025-11-13_20_07 WARNING: print-datetime-link-cross-x86_64-1.0-r0 do_install: print-datetime-link-cross-x86_64 current DATETIME in symlink is 2025-11-13_20_07 WARNING: print-datetime-usenative-1.0-r0 do_install: print-datetime-usenative current DATETIME from print-datetime-link is 2025-11-13_20_07 It's because print-datetime-link-cross-x86_64 depsig doesn't include print-datetime-native signature: $ cat tmp/work/x86_64-linux/print-datetime-link-cross-x86_64/1.0/temp/depsig.do_populate_sysroot OEOuthashBasic 18 SSTATE_PKGSPEC=sstate:print-datetime-link-cross-x86_64:x86_64-oe-linux:1.0:r0:x86_64:14: task=populate_sysroot drwx . drwx ./recipe-sysroot-native drwx ./recipe-sysroot-native/sysroot-providers -rw- 32 19fbeb373f781c2504453c1ca04dab018a7bc8388c87f4bbc59589df31523d07 ./recipe-sysroot-native/sysroot-providers/print-datetime-link-cross-x86_64 drwx ./recipe-sysroot-native/usr drwx ./recipe-sysroot-native/usr/bin drwx ./recipe-sysroot-native/usr/bin/x86_64-oe-linux lrwx ./recipe-sysroot-native/usr/bin/x86_64-oe-linux/print-datetime-link -> ../print-datetime While print-datetime-link-native doesn't have this issue, because print-datetime-native signature is there: $ cat tmp/work/x86_64-linux/print-datetime-link-native/1.0/temp/depsig.do_populate_sysroot OEOuthashBasic 18 print-datetime-native: 60f2734a63d708489570ca719413b4662f8368abc9f4760a279a0a5481e4a17b quilt-native: 65d78a7a5b5cbbf0969798efe558ca28e7ef058f4232fcff266912d16f67a8b8 SSTATE_PKGSPEC=sstate:print-datetime-link-native:x86_64-linux:1.0:r0:x86_64:14: task=populate_sysroot drwx . drwx ./recipe-sysroot-native drwx ./recipe-sysroot-native/sysroot-providers -rw- 26 3d5458be834b2d0e4c65466b9b877d6028ae2210a56399284a23144818666f10 ./recipe-sysroot-native/sysroot-providers/print-datetime-link-native drwx ./recipe-sysroot-native/usr drwx ./recipe-sysroot-native/usr/bin lrwx ./recipe-sysroot-native/usr/bin/print-datetime-link -> print-datetime With the cross.bbclass fix the link-cross recipe has a checksum from native recipe as well: $ cat tmp/work/x86_64-linux/print-datetime-link-cross-x86_64/1.0/temp/depsig.do_populate_sysroot OEOuthashBasic 18 print-datetime-native: 9ceb6c27342eae6b8da86c84685af38fb8927ccc19979aae75b8b1e444b11c5c quilt-native: 65d78a7a5b5cbbf0969798efe558ca28e7ef058f4232fcff266912d16f67a8b8 SSTATE_PKGSPEC=sstate:print-datetime-link-cross-x86_64:x86_64-oe-linux:1.0:r0:x86_64:14: task=populate_sysroot drwx . drwx ./recipe-sysroot-native drwx ./recipe-sysroot-native/sysroot-providers -rw- 32 19fbeb373f781c2504453c1ca04dab018a7bc8388c87f4bbc59589df31523d07 ./recipe-sysroot-native/sysroot-providers/print-datetime-link-cross-x86_64 drwx ./recipe-sysroot-native/usr drwx ./recipe-sysroot-native/usr/bin drwx ./recipe-sysroot-native/usr/bin/x86_64-oe-linux lrwx ./recipe-sysroot-native/usr/bin/x86_64-oe-linux/print-datetime-link -> ../print-datetime And print-datetime-usecross is correctly rebuilt whenever print-datetime-native output is different.
