Error while cross building application for drm-gbm backend

[Khalid-Faisal]

Hi,
I want to perform cross building of application from x64 to arm64. Linux distro is installed in arm64 device which doesn't have packages like apt, apt-get, dpkg etc.
Arm64 device supports drm backend, I followeds steps mentioned in Cross Building using Bitbake. I am able to setup Yocto for drm-gbm backend. When I try to build using below command,

flutter-elinux build elinux --target-arch=arm64 --target-compiler-triple=aarch64-poky-linux --target-backend-type=gbm --target-sysroot=/opt/poky/3.1.17/sysroots/aarch64-poky-linux

I am getting erros, logs are as follows

Building an eLinux application with gbm backend in release mode for arm64 target...        13.0s

Did you ever find a solution to this? I'm trying to do the same: avoiding using systemd. Getting the same error.
