The autotools fix would be: # setcap may not exist on the host CACHED_CONFIGUREVARS = "ac_cv_path_SETCAP=${sbindir}" Unfortunately I don't know the meson equivalent. The diffoscope difference shows a dependency on libcap in some builds and not in others. 86370 1 crg7475 2020-02-07 06:12:55 +0000 The relevant location in the meson based builds is here: https://gitlab.freedesktop.org/gstreamer/gstreamer/blob/master/libs/gst/helpers/meson.build#L67 This meson.build file also contains PTP related checks that may similarly cause nondeterministic builds, though I am not sure this really is the case. Worth checking too. 86482 2 alex.kanavin 2020-02-19 15:38:32 +0000 I think simply adding a dependency on whatever native recipe provides setcap, and then making sure target libcap is there as well should be enough? 86483 3 alex.kanavin 2020-02-19 15:38:58 +0000 Reading that meson code, it does look for setcap in PATH first before falling back to hardcoded host paths. 86493 4 richard.purdie 2020-02-19 21:30:45 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=29d57a9e270c64b523021a65fdde140efb40e3c7
