           Product: xorg
           Version: 6.99.99.904 (7.0 RC4)
          Platform: x86 (IA32)

Hi to all,
         I'm currently using Fedora Rawhide 12 Constantine.
I also complile D.R.M the unamed git repository for the nouveau kernel
moudules,Mesa and the Nouveau driver form git.My graphics card is an nvidia
geforce 6,800 G.T with 256Mb of memory,my monitor is a A.D.I Microscan G1000.

I've been building the former source code from git ok,but I'm having
trouble
building the Nouveau driver.I update the commits from the nouveau git
repository regulary.

The problem is after ./configure and then run make.I'll try and type the
error
I'm getting as accurately as possible:

Make all-recursive
make[1]: Entering directory '/opt/xf86-video-nouvuea'
Making all in src
make[2]: entering directory '/opt/xf86-video-nouveau/src'
CC nouveau_exa.lo
nouveau_exa.c: In function 'nouveau_exa_init'
nouveau_exa.c:576:error:'EXA_MIXED_PIXMAPS'undelclared(first use in this
function
nouveau_exa.c:576:error:for each function declared in)
make[2]:*** [nouveau_exa.lo] Error1

I hope anybody can solve this problem.
Regards,
       STEVE555

Excerpt from #nouveau:
10:14:41 < okias> Hello, have anyone idea why i can't compile ddx?
http://pastebin.ca/1523661
10:15:25 < darktama> okias: your xserver isn't new enough

where the referred paste contains the same bug as you:
nouveau_exa.c:576: error: ?EXA_MIXED_PIXMAPS? undeclared (first use in this
function)

It was introduced in the DDX commit commit
30ddd08bb2739514edf6d6e137f533b34a4369d2, "exa: turn on new exa migration
mode
for driver pixmaps".

The "fix" is in xorg-server commit 
http://cgit.freedesktop.org/xorg/xserver/commit/?id=03ecb164f2592c954aa408bf121e0c67b604d854
"exa: A simple 3rd backend implementation.", so the solution is to
update your
xorg-server from git.

An alternative solution is to downgrade xorg-server to a version prior EXA 2.5.
Today that means any xorg-server version officially released.

Closing as not a bug.

The driver needs to check that EXA_MIXED_PIXMAPS is defined before using it.
The radeon driver just guards that code by #ifdef EXA_MIXED_PIXMAPS.

Michel:  While it would be easy enough to do that, sure, I have no intentions
of attempting to preserve compatibility between pre-release servers.  We
currently check for >= EXA 2.5 before assuming mixed pixmaps are available,
that seems sufficient no?

If it was sufficient, would this report exist? If Maarten intended the minor
version to be used for this, he should have bumped it.

Even if it was sufficient, from my POV it's unnecessarily both more
complicated
and limiting than just #ifdef EXA_MIXED_PIXMAPS. But of course it's
ultimately
up to you.

The reporter is using non-released software, it shouldn't be unexpected that
things break.  Why bother with compatibility for something that's never
going
to make it into a release?  Are we going to do the same when CreatePixmap2()
gets modified again before the release?  In which case we have #ifdefs for 3
different APIs...

It's no real trouble to allow use of both, I just didn't see the point. 
Not to
mention that before mixed pixmaps, driver pixmaps were essentially unusably
slow on some chipsets.

(In reply to comment #5)

How would you handle that with #ifdefs? It's gonna need an EXA version
change
(minor bump, probably).
> It's no real trouble to allow use of both, I just didn't see the

Bisectability, e.g.?

Anyway, I think I've presented my arguments and am going to stop now. Do as
you
see fit.

Hi guys,
       As of the latest updates tonight,the nouveau driver from git builds
successfully now.The latest xorg package version is now 1.6.99-33.20090807.

I would like to thank you very much for trying to help me.

I have a build problem with Mesa,but I'm going to file a different bug
report
on that one.

With your permission,I'm going to close this bug as fixed.

Regards,
       STEVE555
