$ lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300 GE] (rev a1)

Someone else replicated the problem with a nv94 card.

reproduct and confirm this problem with:
01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300M GS] (rev a1)

I found, it's in src/gallium/target/egl/egl.c failed to dlopen("pipe_nouveaus.so", ...).

Who know why dlopen() failed? Since all so files are there.

Looks like this was fixed in:

commit 84ebd8e2d7b13cf43069a2b79168cf7a1df02b71
Author: Vinson Lee <vlee@vmware.com>
Date:   Thu Jan 6 00:06:38 2011 -0800

    nvc0: Fix typo of nvc0_mm.c in SConscript.

I no-longer believe this is fixed.  84ebd8e2d7b13cf43069a2b79168cf7a1df02b71 is giving me the same "failed to create DRM screen" error as I had been getting.  Don't know why I thought it was fixed.

6a102074bb30e44273e999ee8cdd2afbfbc4e333 still works.
997f84ff4efb62779a19f6bd0441cbae1b7bad70 still doesn't work.

This (and my previous report of it working) is on a different card:

$ lspci | grep -i vga
05:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce 8800 GT] (rev a2)

(The latest commit is also not working: 6d9ca78ef7bf831b9b63f4bda68623cbae627508 )

Also, strace shows pipe_nouveau.so being opened, it just doesn't get mentioned in the output.

Full output:

wayland compositor strace output, failing, commit 6d9ca78ef7bf831b9b63f4bda68623cbae627508 (latest)

if it's still a linking problem running wayland with LD_DEBUG set to "all" might help find the root cause

The wayland compositor is now starting, but shows up as a completely garbled apparently random chunk of video memory.

Ignore my last comment, it shows I was loading all the wrong libraries, instead of from ~/install/

/home/darxus/install/lib/egl/pipe_nouveau.so: error: symbol lookup error: undefined symbol: nvc0_screen_create (fatal)

These commands should fix it:

make distclean
./autogen.sh
./configure ...
make

Wiped my entire build and install directories, recloned and built everything, same error.

Still getting:

fixed by commit 69191d41231b95af7565e32393c5487163859d7e "targets/egl: add libnvc0.a to nouveau libs"

Confirmed, works with commit 69191d41231b95af7565e32393c5487163859d7e
