Might be similar to the issue shown in bc recently: https://git.openembedded.org/openembedded-core/commit/?h=kirkstone&id=400ed3bc77232b9d67594fa012b1278a6c8be3c6 but in this case we need to prevent the rebuild (as I don't see how python2 gettest.py could have worked in dunfell builds before) Without meta-updater setting SOURCE_DATE_EPOCH to 0 and with libxml2/2.9.14 used in kirkstone I see usable timestamps: -rw-r--r-- 3 bitbake bitbake 1448791 May 2 11:42 libxml2/2.9.14-r0/libxml2-2.9.14/testapi.c -rwxr-xr-x 1 bitbake bitbake 30753 May 2 10:52 libxml2/2.9.14-r0/libxml2-2.9.14/gentest.py* so this isn't needed in kirkstone. > diff --git a/meta/recipes-core/libxml/libxml2_2.9.10.bb > b/meta/recipes-core/libxml/libxml2_2.9.10.bb > index b3ebf15751..d1c1f0884f 100644 > --- a/meta/recipes-core/libxml/libxml2_2.9.10.bb > +++ b/meta/recipes-core/libxml/libxml2_2.9.10.bb > ... > do_compile_ptest() { > + # Make sure that testapi.c is newer than gentests.py, because > + # with reproducible builds, they will both get e.g. Jan 1 1970 > + # modification time from SOURCE_DATE_EPOCH and then check-am > + # might try to rebuild_testapi, which will fail even with > + # 0001-Port-gentest.py-to-Python-3.patch, because it needs > + # libxml2 module (libxml2-native dependency and correctly > + # set PYTHON_SITE_PACKAGES), it's easier to > + # just rely on pre-generated testapi.c from the release > + touch ${S}/testapi.c > + > oe_runmake check-am > } >
