[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,

Hi,

According to this https://elrepo.org/tiki/kmod-nvidia (scroll to the
bottom of the page), glamor is conflicting with nvidia-driver.
It seems to build fine with:
ifeq
($(BR2_PACKAGE_HAS_LIBGL)$(BR2_PACKAGE_LIBEPOXY)$(BR2_PACKAGE_NVIDIA_DRIVER),yyn)
instead of 
ifeq ($(BR2_PACKAGE_HAS_LIBGL)$(BR2_PACKAGE_LIBEPOXY),yy)

Regards,

BR2_PACKAGE_NVIDIA_DRIVER will never be 'n', so it means the condition
will never be true.

What's written at https://elrepo.org/tiki/kmod-nvidia is that there is
a runtime issue, not a build time issue, so it's a bit surprising.
