[Buildroot] bug in xserver compilation?

[Buildroot] bug in xserver compilation?

[daggs]

Greetings,

I'm trying to add a new ddx driver to buildroot from aarch64 and I've encountered a strange issue.
so I've decided to try and reproduce it with are more stable env, Iv'e ran make pc_x86_64_bios_defconfig, then entered menuconfig.
in it I've enable c++ support, modular xserver and finally the intel xf86 video.
I've hit make and waited, when buildroot got to xserver. it failed with the following error more than once:
/home/dagg/workspace/buildroots/buildroot-master3/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/include/xf86drm.h:40:17: fatal error: drm.h: No such file or directory
 #include <drm.h>

I've ran a sanity check on the output dir:
dagg at NCC-5001-D ~/workspace/buildroots/buildroot-master3 $ find output/ -name drm.h
output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/include/drm/drm.h
output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/include/libdrm/drm.h
output/build/libdrm-2.4.70/include/drm/drm.h
output/build/linux-headers-4.6.3/usr/include/drm/drm.h
output/build/linux-headers-4.6.3/drivers/gpu/drm/tegra/drm.h
output/build/linux-headers-4.6.3/include/uapi/drm/drm.h
output/target/usr/include/libdrm/drm.h

I think this is a bug, am I wrong?

the actual config I've used can be found at http://bpaste.net/show/45998ef4aed6

The xdriver_xf86-video-intel was updated just tonight. Did you observe
the build failure before it was updated, or after it was?

This is a known issue. Bernd posted a patch to fix it "[PATCH 1/2]
package/x11r7/xserver_xorg-server: add libdrm-specific cflags" but I
wasn't happy with it. You can see my reply from this Monday in the
mailing list archives.

I didn't updated my local copy lately.
the issue in hand is with xserver and libdrm.
it seems that libdrm is installed but zserver doesn't find it in the include path. see the compilation error and the find output I've attached.

thanks for info., is this a version related regression?

I have no idea. I believe the problem has existed for a while, but I'm
not sure.

A proper patch is welcome, though :)
