[Buildroot] Error while build Xorg with nvidia-driver

[Alexandre Maumené]

Hi,

I'm trying to build Xorg (with nvidia-driver) and I have this error:
[...]
checking for GLAMOR... yes
checking for GBM... no
configure: error: Glamor for Xorg requires gbm >= 10.2.0

I'm not sure to understand if I the Nvidia proprietary drivers support
gbm or not and if I actually need to build Xorg with glamor. I have
found much examples on internet on how to build buildroot with Nvidia
drivers. (but nouveau isn't really good for what I'm trying to build).

Any help would be appreciate !

Regards,
