Since upstream commit
eec95e3d5e1a4f2e13b1f6b34cc287475ca57daf ("backend/drm: use pnp.ids to
fetch EDID data"), the pnp.ids file from hwdata is parsed at build
time to generate a C source file. As per backend/drm/meson.build:
hwdata = dependency('hwdata', required: false, native: true)
if hwdata.found()
hwdata_dir = hwdata.get_variable(pkgconfig: 'pkgdatadir')
pnp_ids = files(hwdata_dir / 'pnp.ids')
else
pnp_ids = files('/usr/share/hwdata/pnp.ids')
endif
This is only needed when the DRM backend of wlroots is enabled, but
currently, Buildroot enables this backend unconditionally.
This failure can be reproduced using the following defconfig:
BR2_x86_64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_OSMESA_GALLIUM=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_MESA3D_OPENGL_ES=y
BR2_PACKAGE_WLROOTS=y
The issue was not caught in the autobuilders because the last
successful build of a configuration that includes wlroots dates back
from 2022-05-05, at which time Buildroot had wlroots 0.15.1.
This change in wlroots was introduced in wlroots 0.16.0, which means
that it's only since Buildroot bumped from 0.15.1 to 0.16.2 in
d6279bc82c ("package/wlroots: bump to
version 0.16.2") that the issue occurs. This commit is not yet in any
tagged release, so there is no need to backport this fix.
It should be noted that the proposed patch also installs pnp.ids to
the target filesystem, while it is in practice not needed at runtime
by wlroots. However, our current hwdata packaging doesn't allow
installing it only in staging, and since wlroots anyway implies we're
building a fairly heavy graphics stack, the size overhead of hwdata is
deemed to be an acceptable trade-off.

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 OFTC IRC.
