Issue while building flutter-engine on a imx8mm platform

[fleroyener]

Hi,

I have this issue with the compilation of flutter-engine recipes. First i had the issue that i don't have goma :

| ________ running 'python3 src/flutter/tools/githooks/setup.py' in '/home/build/tmp/work/armv8a-mx8mm-poky-linux/flutter-engine/1.0-r0'
| Traceback (most recent call last):

|   File "./flutter/tools/gn", line 254, in to_gn_args
|     gn_args.update(setup_goma(args))
|   File "./flutter/tools/gn", line 224, in setup_goma
|     raise Exception(
| Exception: GOMA was specified but was not found. Set the GOMA_DIR environment variable, install goma at $HOME/goma following the instructions at https://github.com/flutter/flutter/wiki/Compiling-the-engine, or run this script with the --no-goma flag to do a non-goma-enabled build.

Soo, i tried to add this in a bbappend : GN_ARGS:append = " --no-goma"

And then the issue is different :

am i doing something wrong ? Maybe i need to add someting on GN_ARGS to disable x11 ? My platform is wayland / weston so i will use flutter-wayland-client recipe

You need to add x11 to DISTRO_FEATURES. See also https://github.com/meta-flutter/meta-flutter/commit/dc90eaef0e72d7e207866e1e73906a71b7ffb027

Ok thanks, i tried to use fsl-imx-xwayland for distro and it's works for engine compilation.
