talos-openbmc: build failure

[resonant]

i am using a fedora-32 vm to build the openpower and openbmc firmware, and have setup the debian-chroot config per

https://wiki.raptorcs.com/wiki/Compiling_Firmware

the openpower fw built fine (apart from some messages about signing keys), but i have hit a build error for the raptor-v2.00 branch of talos-openbmc. it fails during obmc-phosphor-initfs.bb:do_install and here is the build log

as you can see, the bbe binary is missing.

advice appreciated.

i decided to take a shot at doing this using a debian 9 vm and the build has failed at the same point.

i had one of the devs i work with take a look at the commit messages for the talos-openbmc repo and he didn't see anything obvious suggesting this issue has been fixed in a commit since the latest raptor-v2.00 commit.

holy brittle build toolchain, batman!

the fix here ended up being to determine which bitbake recipes were responsible for the missing files, then forcing a clean and install on those specific recipes:

bitbake -f -b /home/user/talos-openbmc/meta-rcs/recipes-phosphor/binary-block-editor/binary-block-editor.bb -c clean
bitbake -f -b /home/user/talos-openbmc/meta-rcs/recipes-phosphor/binary-block-editor/binary-block-editor.bb -c install

i also had to do the same for meta-aspeed/recipes-bsp/u-boot/u-boot-fw-utils-aspeed_2016.07.bb. after this, you can restart the build with the usual bitbake obmc-phosphor-image command.

this really should be documented in the wiki so anyone else having the same issues doesn't have to figure out how bitbake works.
