SK-AM62B-P1: Getting weird error messages while running bitbake after adding Flutter meta payer

Hi Davit,

Can you try using the latest top-of-branch `scarthgap` from here https://github.com/meta-flutter/meta-flutter as part of your setup? I was told important improvements were made, that should help compatibility in the context of SDK v10.x.

Regards, Andreas

Hi Andreas,

Thank you for taking the time to answer me. Actually I took the latest 'scarthgap' top-of-branch commit, which is Dec 19 commit 4add4040f42c6a9e816f056af5b14ebf68f840fb. But still getting the same kind of error:

ERROR: ParseError at /home/davmelikyan/QuickSilver/processor-AM62X/tisdk/sources/meta-flutter/meta-flutter-apps/recipes-graphics/flutter-apps/first-party/flutter-samples-navigation-and-routing-bookstore_1.0.0.bb:25: Could not inherit file classes/flutter-app.bbclass
ERROR: Parsing halted due to errors, see error messages above

Thanks,

Hi Davit,

Let me try to setup a test build to see if I can re-create this and report back here.

Hello Andreas,

The problem comes from the malfunctioning script:

./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-scarthgap-flutter-10.00.07.04-config.txt

As it is supposed to create in tisdk/build/conf/bblayers.conf file under BBLAYERS+=  /home/user/tisdk/sources/meta-flutter \

But I can see that in tisdk/build/conf/bblayers.conf there is no meta-flutter layer entry in bblayers.conf and it only creates meta-flutter-apps entry for some reason. This brings to the mentioned error. 

I think this should be escalated to TI support so they can fix the oe-layertool-setup.sh script.

Thanks,

Davit

Good find. First I was able to re-create your error, but then after adding both of...

        /home/a0797059/tisdk/am62xx-evm/sources/meta-flutter \
        /home/a0797059/tisdk/am62xx-evm/sources/meta-flutter/meta-flutter-apps \

...to conf/bblayers.conf the build seems to start successfully. Let me see if it goes all the way through and then figure out how we can best resolve this officially. Adding `meta-flutter` to the config script (.txt file) doesn't seem to work as-is as a solution, as this change won't make it past the `verify_layers()` function inside oe-layertool-setup.sh. It looks like the `meta-flutter` layer is somewhat constructed in a non-standard way.

Hello Andreas,

Still having trouble with the yocto build. It's either crashes at some point along-with the terminal or ending with building errors like:

Summary: 3 tasks failed:
/home/user/processor-AM62X/tisdk/sources/meta-qt5/recipes-qt/qt5/qtmultimedia_git.bb:do_compile

Summary: There were 9 WARNING messages.
Summary: There were 6 ERROR messages, returning a non-zero exit code.

Tried to run it several times still no success.

Running build using processor-sdk-scarthgap-10.00.07.04-config.txt without Flutter meta layer was pretty smooth though.

Thanks,

Davit

Hi Davit,

I just checked, my build went to completion, without any issues.

Try deleting the entire build folder. Then before re-starting, also dial down the parallel build like shown below (may try even smaller numbers, really depends on your setup) by updating conf/local.conf accordingly, you might be running out of memory during build, which can result in strange issues like bitbake-server hangs etc.
