I guess my libflutter_elinux_gbm.so version can’t match，If so, which version should I specify

The cause is that `drmIsMaster' API doesn't seem to be supported in your environment for cross-building.

Li-00 commented 1 year ago

I found that my target-backend-type parameter was specified incorrectly, it should be x11 for my graph architecture, and it works fine after making the change

flutter-elinux build elinux --target-arch=arm64 --target-sysroot=/ --target-backend-type=x11 --verbose

Sorry, this is due to insufficient knowledge of the graphics backend library, thanks to HidenoriMatsubayashi for the follow-up reply
