Re: [Chromium-users] crserver & crappfaker won't start

[Dan B. P. <ph...@cs...>]

your current working doesn't matter if you have the correct environment 
variables.  try adding these other exports:

export LD_LIBRARY_PATH=~/cr-1.9/lib/Linux

add this to the PATH export Brian suggested below.  the crserver and 
crappfaker are in ~/cr-1.9/bin.  If that still doesn't work, you should 
paste the output from the commands.

hello brian,
it didn't make a change at all :(

I think, it would help a lot, if someone could explain,
from which directory crserver and crappfaker have to get startet,
right after having run these commands:

[Chromium-users] crserver & crappfaker won't start

[mel <rom...@we...>]

Hello @all,

I was trying to run Chromium on my notebook before installing it to our
Linux-Cluster.

I have some problems getting the demo applications startet.

So long, I tried to start like this:

--------------------------------------------------------
mel@book:~$ cd cr-1.9/
mel@book:~/cr-1.9$ cd mothership/configs/
mel@book:~/cr-1.9/mothership/configs$ python crdemo.conf atlantis &
[1] 6403
mel@book:~/cr-1.9/mothership/configs$ This is Chromium, Version 1.9
Start a crappfaker on book
Start a crserver on book
--------------------------------------------------------

And now, that's the big question ;) from which directory should crserver and
crappfaker get startet?
As read in "Beginner's guide to Chromium", I tried to go on with the steps
(in the same directory as before):
3: % crserver &
4: % crappfaker
... but that's not working at all:

mel@book:~/cr-1.9/mothership/configs$ crserver &
[2] 6516
mel@book:~/cr-1.9/mothership/configs$ bash: crserver: command not found

I tried to run both commands out of bin/Linux - but that gives the following
errors:

--------------------------------------------------------
mel@book:~/cr-1.9/bin/Linux$ ./crappfaker
./crappfaker: error while loading shared libraries: libcrmothership.so:
cannot open shared object file: No such file or directory
mel@book:~/cr-1.9/bin/Linux$ ./crserver
./crserver: error while loading shared libraries: libspuload.so: cannot open
shared object file: No such file or directory
--------------------------------------------------------

I'm very new to this all and can't figure out what's the problem... I
suppose that some environment variables aren't set correctly...?

Does anyone have a clue?

Thank you very much,
best regards,
mel

[Chromium-users] Compiling on Win32

[Phil S. <Ph...@nw...>]

Hi!

I am an experienced Linux user, but comparatively having no idea about
Windows. I guess this is why I am having major problems compiling
Chromium on my (KVM powered) WindowsXP.
I am very sure all necessary software packages are installed, including
Cygwin and MSVC8, but unfortunately this is also where documentation
ends at.
AFAICT there are two different approaches in building Chromium:
1) using the Cygwin shell (the window running bash in a Unix like
   filesystem) and
2) using the MSVC shell (simple cmd.exe with appropriate environment)

Using the first approach I am unable to run cl.exe. After adjusting the
$PATH variable cl.exe is being found, but no output occurs (when started
with strace.exe, a pop-up window is shown telling me about a missing
dll) - I love this s**t.

When trying the second approach, it starts with a missing make.exe.
After adjusting %PATH% here, windows.h is not found (yes, it's
%INCLUDE%). So I added C:\cygwin\include\w32api to the include-path, but
still no luck: at compilation, cl.exe complains about deprecated flags
(just warnings, so "/ignore"). Next I get lots of errors, the first few
telling me "alignment has changed after including <foobar.h>". (I guess
cl.exe doesn't like unix style newlines?)

Maybe someone of you could give me a short hint on how to setup a shell
(no matter which) environment correctly enough to be able to compile
Chromium?

Thanks in advance,
Phil

See http://vncproxy.sourceforge.net/

The basic idea is to use the XF4VNC module to send your X desktop to a=20
VNC viewer (or the VNC Proxy).  Then, use the Chromium VNC SPU to=20
convert GL rendering into VNC protocol.  Those two sources get sent to=20

[Chromium-users] Chromium + VNC SPU + full desktop?

[Dan B. P. <ph...@cs...>]

Is there a way to run a full desktop using Chromium over VNC?  I tried 
having the application be something like 'gnome-session', but the VNC 
SPU uses the render's display for the window manager.  This model would 
have everything being rendering by the render spu, opengl + Xlib, 
etc....So maybe my attempt was just destined to fail. 

The other way I see of doing this is to have a modified VNC server and 
some other glue/hacks that ensure that opengl commands get routed to the 
CR lib.  If the user wants to have the rendering happening on the 
client, the vncviewer would have to be modified to start a crserver, 
render spu, etc....

Does any of this exist?

Re: [Chromium-users] [Rocks-Discuss] Chromium not displaying some applications

[Nino P. <np...@gm...>]

Hi Brian,

Yes it worked, thank you.

Now we are experiencing an odd behaviour: Yesterday Amira worked, but Maya
did not. Today Maya is running and Amira is not.
We have deleted the cr-1.9 tree, decompressed the tar file, applied again
the patch and compiled and Amira is not running (XDMX+Chromium+Amira). Amira
is running fine on Chromium, but without XDMX (yesterday it worked with
XDMX, but Maya did not).

The previous error in Maya no longer appears, but the menus are not working,
if you click on a menu it stays there and never disappears.

We even have rebooted the machine, and recompiled several times... i don't
understand this behaviour.

Tried with different versions of nvidia drivers. Can't reproduce how to make
work one o.k.


Thank you.

This is the main Mesa/OpenGL library.

This the the OpenGL utility function library.

Use the latest versions of both packages.

BTW, If you're using NVIDIA or ATI hardware, you'll need to install 
their driver packages after the above.

Re: [Chromium-users] [Rocks-Discuss] Chromium not displaying some applications

[Nino P. <np...@gm...>]

Hi,

In a previous cluster installation both applications where running OK in
XDMX and Chromium.

Which packages has to do with OpenGL in REHL?

xorg-x11-Mesa-libGL?
xorg-x11-Mesa-libGLU?

Which version will be compatible with Chromium, in order for Maya and Amira
display as it should?

Thank you.

That looks like they're taking advantage of some OpenGL 2.0 features
which haven't hit the Chromium tree yet.

[Chromium-users] Chromium not displaying some applications

[Nino P. <np...@gm...>]

Hi,

We have a viz-wall of 3x1, running Chromium 1.9 and XDMX.

We have some OpenGL applications running fine, but when we try to run Maya
8.0 or Amira 3.1, the applications does not load correctly, we have no
interaction with the menus (click on them triggers no action) and some
buttons does not appear.

This is the error we get:

CR Error (tile-0-0:7794): Invalid pname to __numValues: 0x8871



Any hint?

Thank you.

[Chromium-users] chromium-dmx-stereo

[Daniel C. <dan...@ya...>]

Hello, I have a viz-wall cluster (3x1),  I made this
config file for view active stero in a non-stereo
application with dmx support. When I start all, my
display looks well in only one crserver , but when I
resize it into the anothers crservers, the  whole
display turns very slow, and the animations of the
atlantis demo stop.

Someone know what is happening ?

Oops, I spoke too soon.  It looks like you're trying to connect two 
crservers to one pack SPU:

client_spu.AddServer( server_node,  protocol='tcpip', port=7000 )
client_spu.AddServer( worker_node,  protocol='tcpip', port=7001 )

That's illegal.  The pack SPU can send a stream to only one crserver.
You'll need to use the tilesort SPU to send rendering to two or more 
crservers.

I'll check in a better error message.

They are all running on the same host at present so I can't see
what the problem is.

If you've started the mothership process/script on one host (say 
"host1") and you're running the crappfaker (or crserver) on a different 
host, you need to tell the crappfaker/crserver where to find the mothership.

You can do this by setting the CRMOTHERSHIP env variable (export 
CRMOTHERSHIP=host1) or passing the -mothership command line option 
(crappfaker -mothership host1).

[Chromium-users] problem extending demo examples

[Smith, I. <I.C...@li...>]

Hi,

I'm having problems extending the crdemo_full.conf example to run
with more than one server. At present I'm happy just to run all
of the processes on a single host before trying them on our Linux
cluster. I think I've placed a crserver on port 7000 and another
on port 7001 (they are definitely listening there) but when I=20
run the crappfaker I get this:

-bash-2.05b$ crappfaker
CR Warning(ulgbc2:31341): Couldn't find the CRMOTHERSHIP environment =
variable, defaulting to localhost
CR Warning(ulgbc2:31342): Couldn't find the CRMOTHERSHIP environment =
variable, defaulting to localhost
CR Error(ulgbc2:31342): Bad server specification for Pack SPU 2
CR Error(ulgbc2:31324): Mothership didn't like my accept request

Thank you for using Chromium!
CR Error(ulgbc2:31330): Mothership didn't like my accept request
[2]-  Done                    crserver

Any idea what the problem is here ? This is the conf file:

import sys
sys.path.append( '../server' )
from mothership import *

if len(sys.argv) > 3 or len(sys.argv) < 2:
        print 'Usage: %s <demo> [spu]' % sys.argv[0]=20
        sys.exit(-1)

demo =3D sys.argv[1]

if len(sys.argv) =3D=3D 3:
        clientspuname =3D sys.argv[2]
else:
        clientspuname =3D 'pack'

server_spu =3D SPU( 'render' )
client_spu =3D SPU( clientspuname )
worker_spu =3D SPU( 'render' )

server_spu.Conf( 'window_geometry', [500, 500, 500, 250] )
server_node =3D CRNetworkNode( )
server_node.AddSPU( server_spu )

worker_spu.Conf( 'window_geometry', [0, 0, 500, 250] )
worker_node =3D CRNetworkNode( )
worker_node.AddSPU( worker_spu )

if (clientspuname =3D=3D 'tilesort' ):
        server_node.AddTile( 500, 500, 500, 250 )
        worker_node.AddTile( 0, 0, 500, 250 )

client_node =3D CRApplicationNode( )
client_node.AddSPU( client_spu )
client_spu.AddServer( server_node,  protocol=3D'tcpip', port=3D7000 )
client_spu.AddServer( worker_node,  protocol=3D'tcpip', port=3D7001 )

client_node.SetApplication( os.path.join(crbindir, demo) )
client_node.StartDir( crbindir )

cr =3D CR()
cr.MTU( 16*1024 )
cr.AddNode( client_node )
cr.AddNode( server_node )
cr.AddNode( worker_node )
cr.Go()NetworkNode( )

The original demo worked fine. I'm running under Red Hat Enterprise=20
Linux AS release 3.

Any thoughts - I'm completely lost.

thanks,

[Chromium-users] Chromium with wxWidgets

[Chris J. <cr...@gm...>]

Hi.  I'm having trouble getting a wxWidgets application to run under
Chromium.  And, I don't know how to figure out why, exactly.  Here's
the minimal output from running the crdemo configuration on my local
machine:

$ python crdemo.conf myapp &
Start a crappfaker on localhost.localdomain
Start a crserver on localhost.localdomain
$ crappfaker &
CR Warning(rover:17859): Couldn't find the CRMOTHERSHIP environment
variable, defaulting to localhost
CR Debug(rover:17859): In crNetConnectToServer( "localhost",
port=10000, mtu=8096, broker=0 )
CR Debug(rover:17859): Connecting to rover on port 10000, with protocol tcpip
CR Debug(rover:17859): Done connecting to localhost (swapping=0)
CR Warning(rover:17860): glXChooseFBConfig not implemented by Chromium
CR Error(rover:17859): "/path/to/myapp" terminated with uncaught
signal=11 (SIGSEGV)

I experience the same results with my application and with the
wxWidgets OpenGL samples.  It looks like Chromium returns NULL on the
glXChooseFBConfig call.  It seems that wxWidgets is trying to
dereference the returned value, doesn't it?  For what it's worth,
wxWidgets isn't built as a static library.

I'd appreciate any guidance in trying to get this working.  Let me
know what information I can provide.

[Chromium-users] chromium-dmx-stereo

[Daniel C. <dan...@ya...>]

Hello everybody, I have a problem running chromium on
dmx with force stereo option (crystal-eyes), because
the clients  nodes render (tilesort) on dmx use the
app-window for display:

renderspu.Conf('render_to_app_window', 1)

but it seems that this window can not makes this kind
of rendering.

Somebody know something about it.


Regards.
Daniel.

[Chromium-users] tips for darwin?

[Dan P. <ph...@cs...>]

Hi, I just gotta macbook and wanted to try out chromium on it. 

Are there tips on how to build CR for Darwin?  I do see the note on the 
chromium wiki about installing the Apple Developer Tools for for using 
DYLD_LIBRARY_PATH, but...I that doesn't seem to be enough.  I installed 
the glut libs using 'port', but the build process is having trouble 
finding the other libs.  Here's what I did:

$ mkdir ~/work/chromium; mv cr-1.9.tar.gz !:1; cd !:1
$ tar xzf cr-1.9.tar.gz
$ cd cr-1.9
$ export DYLD_LIBRARY_PATH=`pwd`/lib/Darwin
$ make

-------------------------------------------------------------------------------
              Building libcrutil.dylib for Darwin (RELEASE)     
-------------------------------------------------------------------------------
ln: /cr/include/GL/glut.h: No such file or directory
make[1]: *** [arch] Error 1
make: *** [util.subdir] Error 2

I'm pretty sure I'm missing something basic here...but the build from 
linux was this easy, was hoping darwin to be similar...If here's a wiki 
or howto somewhere that I could follow along, that'd be great.  
Otherwise, the info I get here will go into one!

tia,
dan

[Chromium-users] multi viewports

[Thomas C. <tho...@gm...>]

Hi,

We want to run an application displaying several OpenGL viewports, one
viewport per crserver.

I tried the bucketing algorithms of the tilesort SPU. It works well with one
viewport, but with several viewports it seems that all the geometry is sent
to all the tiles, the glViewport commands doesn't affect the bucketing
algorithms. Each tile has the correct glViewport settings, but displays the
geometry of all viewports.

Is it possible to setup chromium to do this kind of rendering?

Regards,
Thomas
