This issue has been trigged since [1]:
"package/mesa3d: add option to configure gbm support"
Before the patch, the gbm support was autodetected by meson and enabled
only when at least one dri driver was enabled [2].
On the Buildroot side, the gbm support was explicitely enabled only when
BR2_PACKAGE_MESA3D_OPENGL_EGL was set.
We have two cases:
- At least one DRI driver.
- No DRI driver but one Gallium w/ EGL enable (EGL selected or not by the
Gallium driver). In this case the meson build system set with_dri to true
(even if no DRI driver is enabled) to use the builtin:egl_dri2 [3].
The gbm's meson build system seems to handle the case where no dri driver is
enabled [4] but it still use main/backend.c source file [6] that use
gbm_dri_backend [7]. So with_dri2 must always be set.
Probably a missing check in meson.build:
if with_gbm and not with_dri
error('GBM backend needs a dri driver or a gallium driver w/ EGL support.')
endif
Add a dependency on GBM option:
depends on BR2_PACKAGE_MESA3D_DRI_DRIVER \
|| (BR2_PACKAGE_MESA3D_GALLIUM_DRIVER && BR2_PACKAGE_MESA3D_OPENGL_EGL)
