you need to build against drm-next kernel tree or a different tree the module
is actually based on. Check for the last drm-next commit in the tree.

Ben’s tree is currently built against v4.12-rc3 from Linus’ tree, rather than a
version of drm-next.

However, I think that David is building Mesa here, rather than the kernel. It
seems like you do not have the proper version of libdrm.

Thanks for the replies.  I am trying to build mesa (git/master) and have
rebuilt <span class="hiddenSpellError" pre="rebuilt
">drm (also the
git/master).
Here are the configure flags I use:

    drm  "--with-kernel-source=/<span class="hiddenSpellError"
pre="">usr/src/<span class="hiddenSpellError"
pre="">linux --without-udev"

and

    mesa " --<span class="hiddenSpellError"
pre="">enable-gbm --enable-opengl
--<span class="hiddenSpellError" pre="">enable-gles1
--enable-gles2
--with-gallium-drivers=nouveau  --disable-glamor --<span
class="hiddenSpellError"
pre="">disable-gallium-llvm"

An additional oddity.  I've tried building on two machines and i686 and an
x86_64.  The build fails on the <span class="hiddenSpellError"
pre="the ">i686
but succeeds on the x86_64.

Problem solved.  It turns out that an older or <span
class="hiddenSpellError"
pre="or ">slackware pagage of <span
class="hiddenSpellError" pre="of ">drm
installed its include files in /usr/include/drm nor /usr/include/libdrm,
something that wasn't fixed when calling pkg-config --cflags drm which is
now
libdrm).


I manually removed any drm installed files, ran make uninstall, and
rebuilt/installed with no problems.
