Hi again,

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/${TARGET_PREFIX}compilerlibs (gcc-runtime) replaces original key PREFERRED_PROVIDER_virtual/x86_64-pokysdk-linux-compilerlibs (nativesdk-gcc-runtime).
WARNING: /storage/yocto/test2/sources/meta-openembedded/meta-python/recipes-devtools/python/python3-dateutil_2.8.1.bb: Variable key PREFERRED_PROVIDER_virtual/${TARGET_PREFIX}compilerlibs (gcc-runtime) replaces original key PREFERRED_PROVIDER_virtual/x86_64-pokysdk-linux-compilerlibs (nativesdk-gcc-runtime).

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

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?

I was too fast sending this before I realized that Andrey already reported this in https://github.com/Freescale/fsl-community-bsp-base/issues/17. Will continue there.
