Hi,

following these steps to build master branch has a really strange 
behavior. First build with bitbake bails out hard with tons of WARNINGS 
and ends up with an error in sstate.bbclass.

     $ repo init -u 
https://github.com/Freescale/fsl-community-bsp-platform -b master
     $ repo sync
     $ EULA=1 MACHINE=imx8mm-lpddr4-evk DISTRO=poky source 
setup-environment build
     $ bitbake core-image-base

Here are examples of the WARNING:

----------------

WARNING: 
/storage/yocto/test2/sources/poky/meta/recipes-extended/shadow/shadow_4.8.1.bb: 
Variable key PREFERRED_PROVIDER_virtual/${TARGET_PREFIX}compilerlibs 
(gcc-runtime) replaces original key 
PREFERRED_PROVIDER_virtual/x86_64-pokysdk-linux-compilerlibs 
(nativesdk-gcc-runtime).
WARNING:

(gcc-runtime) replaces original key 
PREFERRED_PROVIDER_virtual/x86_64-pokysdk-linux-compilerlibs 
(nativesdk-gcc-runtime).

-----------------

and in the end of the parsing:

-----------------

     >        spec, extrapath, tname = getpathcomponents(tid, d)

   File "/storage/yocto/test2/sources/poky/meta/classes/sstate.bbclass", 
line 877, in 
getpathcomponents(task='virtual:native:/storage/yocto/test2/sources/poky/meta/recipes-devtools/perl/libxml-parser-perl_2.46.bb:do_populate_sysroot', 
d=<bb.data_smart.DataSmart object at 0x7fd579d6adf0>):
              if splithashfn[0] == "True":
     >            extrapath = d.getVar("NATIVELSBSTRING") + "/"
              else:
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

Summary: There were 1675 WARNING messages shown.
Summary: There were 6 ERROR messages shown, returning a non-zero exit code.

-----------------

The strange thing is that if the build is restarted again with 'bitbake 
core-image-base' the build starts fine and works as expected.

I have tried to narrow this down a bit and my wild guess is that this 
has something with setup-environment script to do. My build host is 
Ubuntu 20.10 (that I know is not a validated build host).

Here is an experiment where I create one build dir with 
setup-environment this ends up in the error described above and works 
the second time. Then I create a new build dir with oe-init-build-env 
and then copy local.conf and bblayers.conf from the first build dir.

     $ EULA=1 MACHINE=imx6qdlsabresd DISTRO=poky source 
setup-environment build
     $ bitbake core-image-base
     <ERROR>
     $ cd ..
     $ . ./sources/poky/oe-init-build-env build2
     $ cp ../build/conf/bblayers.conf conf/
     $ cp ../build/conf/local.conf conf/
     $ bitbake core-image-base
     <OK>

Someone with more insight in setup-environment script and bitbake that 
have an idea?

Regards,
/Peter
