Looks like when you build just opencl-monitor directly, the renaming doesn't
happen in the sysroots, but only for the packaging. So, even though the IPK
gets files renamed with ${BPN} suffix, the same files in sysroots are
installed w/o such suffix, leading to conflicts with dspdce-fw and also
ipc-test-fw after it got update-alternatives added.
BTW, do_install_append can be machine-speicfic to dra7xx...
$ MACHINE=am57xx-evm bitbake opencl-monitor -c cleansstate
$ MACHINE=am57xx-evm bitbake opencl-monitor
$ ls ${TMPDIR}/sysroots/am57xx-evm/lib/firmware/dra7-dsp*
./sysroots/am57xx-evm/lib/firmware/dra7-dsp2-fw.xe66
./sysroots/am57xx-evm/lib/firmware/dra7-dsp1-fw.xe66
Also, the error message looks like this:
ERROR: The recipe dspdce-fw is trying to install files into a shared area when
those files already exist. Those files and their manifest location are:
.../sysroots/am57xx-evm/lib/firmware/dra7-dsp1-fw.xe66
Matched in manifest-am57xx-evm-opencl-monitor.populate_sysroot
Please verify which recipe should provide the above files.
The build has stopped as continuing in this scenario WILL break things, if not
now, possibly in the future (we've seen builds fail several months later). If
the system knew how to recover from this automatically it would however there
are several different scenarios which can result in this and we don't know
which one this is. It may be you have switched providers of something like
virtual/kernel (e.g. from linux-yocto to linux-yocto-dev), in that case you
need to execute the clean task for both recipes and it will resolve this
error. It may be you changed DISTRO_FEATURES from systemd to udev or vice
versa. Cleaning those recipes should again resolve this error however
switching DISTRO_FEATURES on an existing build directory is not supported, you
should really clean out tmp and rebuild (reusing sstate should be safe). It
could be the overlapping files detected are harmless in which case adding them
to SSTATE_DUPWHITELIST may be the correct solution. It could also be your
build is including two different conflicting versions of things (e.g. bluez 4
and bluez 5 and the correct solution for that would be to resolve the
conflict. If in doubt, please ask on the mailing list, sharing the error and
filelist above.
ERROR: If the above message is too much, the simpler version is you're advised
to wipe out tmp and rebuild (reusing sstate is fine). That will likely fix
things in most (but not all) cases.
