Failed to create view controller (DRM backend)
I follow your steps to cross compile with docker.
When I run it on the board, I find that Failed to create view controller FLUTTER_LOG_LEVELS=TRACE FLUTTER_DRM_DEVICE="/dev/dri/card1" /root/bundle/elinux --bundle=/root/bundle
My CPU is rk3568 and my build command flutter-elinux build elinux --target-arch=arm64 --target-sysroot=~/ubuntu18-arm64-sysroot/ --target-backend-type=gbm
I have FLUTTER_LOG_LEVELS=TRACE . But it just print Failed to create view controller.
or where is the log?
[root@RK356X:~/bundle]# FLUTTER_LOG_LEVELS=TRACE FLUTTER_DRM_DEVICE="/dev/dri/ca
rd1" /root/bundle/elinux --bundle=/root/bundle
Failed to create view controller.
Please use debug builds.
flutter-elinux build elinux --target-arch=arm64 --target-sysroot=~/ubuntu18-arm64-sysroot/ --target-backend-type=gbm --debug
HA! I see ^_^
[root@RK356X:~/bundle]# FLUTTER_LOG_LEVELS=TRACE FLUTTER_DRM_DEVICE="/dev/dri/ca
rd1" /root/bundle/elinux --bundle=/root/bundle
[ERROR][ConfigureDisplay(53)] Couldn't get resources
[ERROR][CreateRenderSurface(118)] Failed to create the native window
Failed to create view controller.
According to the log message, drmModeGetResources failed. I don't know your device, "/dev/dri/card1" is correct?
I have tried
[root@RK356X:~/bundle]# FLUTTER_LOG_LEVELS=TRACE FLUTTER_DRM_DEVICE="/dev/dri/ca
rd0" /root/bundle/elinux --bundle=/root/bundle
[INFO][ConfigureDisplay(71)] resolution: 1280x800
/root/bundle/elinux: symbol lookup error: /root/bundle/lib/libflutter_elinux_gbm.so: undefined symbol: drmIsMaste
But there is error drmIsMaste
It seem to be right when you said that
"/dev/dri/card1" is correct
Can you please comment-out drmIsMaster in https://github.com/sony/flutter-embedded-linux/blob/master/src/flutter/shell/platform/linux_embedded/window/native_window_drm_gbm.cc#L29 and try again?
Or can you update your kernel version to more newest version?
Linux RK356X 4.19.206
Maybe I can't update. Because I don't have all the drivers of this official kernel.
I just want to see the result of elinux flutter. So I don't compile it.
I see it has no the api. Can I update the libdrm to fix it?
I think the first one is easier than building of the libdrm. Can you try it? After modifying the source file, you can build libflutter_elinux_gbm.so by the following steps in arm64 docker, and replace /root/bundle/lib/libflutter_elinux_gbm.so with the new libflutter_elinux_gbm.so.
$ cmake -DBUILD_ELINUX_SO=ON -DBACKEND_TYPE=DRM-GBM -DCMAKE_BUILD_TYPE=Release -DENABLE_ELINUX_EMBEDDER_LOG=ON -DFLUTTER_RELEASE=OFF ..

Do I need to set the sysroot?
See https://github.com/sony/flutter-embedded-linux/wiki/Installing-dependent-libraries
After modifying the source file, you can build libflutter_elinux_gbm.so by the following steps in arm64 docker,
Simply, you can build .so file for arm64 on arm64 docker. No sysroot as it's self build on arm64.
Yes, that's right. Because it's easy to build than cross-buildings.
HA! It's too slow.

eglGetDisplay failed on your device, but I'm not sure why it failed. Your device supports OpenGL ES and EGL?

Have you set DISPLAY env? Also x11 or wayland is running on your device?

Is it here? I don't know how to see what you said. The default demo is weston qt.
I find that if I turn on weston and the elinux change to flutter_wayland.so . It works well. That means it has wayland?
And I find that cpu is high performance.
Did you stop Wayland & Weston before running flutter for DRM? see https://github.com/sony/flutter-embedded-linux/wiki/How-to-run-Flutter-apps#2-run-with-drm-backend
And I find that cpu is high performance.
Because you are using debug mode.
if flutter_wayland.so I don't stop the weston.
if flutter_gbm.so I stop the weston, but I don't know how to stop wayland.

I see that $ Ctrl + Alt + F3 # Switching to CUI but I am elinux not ubuntu. I stop weston is ok? Ctrl + Alt + F3 doesn't work for the system.
