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)

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
