[gentoo-user] x11-drm compile failure - linux/config.h not found

[gentoo-user] x11-drm compile failure - linux/config.h not found

[Alan McKinnon]

Hi,

I'm sure I'm missing something here but can't quite pinpoint it.

I want to install x11-drm and compare it to the drm in the mainline 
2.6.19-suspend2-r1 kernel. I've disabled drm in my kernel config as 
required, and emerge x11-drm fails with this error:

In file included from q:36:
/var/tmp/portage/x11-base/x11-drm-20060608/work/drm/linux-core/drmP.h:44:26: 
error: linux/config.h: No such file or directory

line 44 of drmP.h contains this:

#include <linux/config.h>

Which is odd as /usr/include/linux/config.h exists

As far as I can tell from my logs, I had this working previously in 
suspend2-sources-2.6.16-r8 and gentoo-sources-2.6.17-r7

Any pointers before I file a bug?

Does the commandline invoking gcc include something 
like "-I /usr/include/linux"? If not so, there is a bug in the Makefile.

Hi Alan,

you seem to be experiencing bug #156784:

http://bugs.gentoo.org/show_bug.cgi?id=156784

There is a dirty workaround somewhere around comment #15. I'd recommend 
waiting for an updated ebuild, though.

C'Ya,
Jürgen

Yes, that's exactly the one.

That workaround is so ugly it insults other ugly things in the world! I 
think I'll give this x11-drm test a miss, I get OK results with the 
in-kernel drm, and I compile too many kernels almost daily to be 
bothered remembering to set a symlink each time

Thanks for your and Uwe's help though
