[Openchrome-users] drm.h; OpenChrome driver and NetBSD/amd64 3.0 - help fixing build system

[Jan Danielsson]

Hello all,

   I've managed to get the OpenChrome driver working with xorg 6.9 on
NetBSD/amd64 3.0, but it involved some ugly hardcoded paths.

This is how I did it:

1) Get xorg-server files (required by the driver):

   # cd /home/pkgsrc/pkgsrc/x11/xorg-server
   # make

2) Get the OpenChrome driver (as explained in the UniChrome wiki; I'm
building outside the tree)

   $ svn co http://svn.openchrome.org/svn/trunk/unichrome
   $ cd unichrome
   $ xmkmf /home/pkgsrc/pkgsrc/x11/xorg-server/work/xc

So far so good, no problems yet.

3) Build it

   $ make

   This step fails, with the following:

------------------------------------------------

------------------------------------------------

   There seems to be two errors occuring, both involving "drm.h". The
drm.h is not being located from
/home/pkgsrc/pkgsrc/x11/xorg-server/work/xc/programs/Xserver/hw/xfree86/os-suppo
rt/xf86drm.h and from via_drmclient.h.

   "find . -name drm.h" in the /home/pkgsrc/pkgsrc/x11/xorg-server
directory reveals that the file is located in
/home/pkgsrc/pkgsrc/x11/xorg-server/work/xc/extras/drm/shared{,-core}/drm.h.

   Just to get it working, I hard code the references to drm.h in
xf86drm.h and via_drmclient.h. This does get the driver built. And I
have verified that the driver works (Yay!).


   Normally, I would just think "Oh, the include path is wrong in the
make file. I'll fix it!". But truth be told, the build system is a
little bit overwhelming for me. The reason I'm posting this to both the
UniChrome and the NetBSD mailing lists is because I can't even determine
where the problem is.

   I figured as much as: "xmkmf" is a tool for making makefiles for X
related stuff(?). This program is supposed to set up the make file, so
that all relevant files are located. It seems that this tool, however,
does not add
/home/pkgsrc/pkgsrc/x11/xorg-server/work/xc/extras/drm/[shared|shared-core]
to the appropriate include path.

   Could someone explain more in detail what is failing, why, and how to
fix it?
