When I execute: roslaunch openhrp3 falling-box.launch ----Eclipse is invoked and I see the IDE but the start button(s) is disabled. When I use menu GrxUI->Start Simulation, the Graph tab shows 3 windows that seem to be working. The 3D view tab does not have any falling boxes in it. The 3D view tab is blank. What should I do? Also, when I click on the falling-boxes.launch link on the http://code.google.com/p/rtm-ros-robotics/wiki/ROS_English page, I get:

Google

  1. That’s an error.

The requested URL /p/rtm-ros-robotics/source/browse/tags/latest/rtmros_common/openhrp3/launch/faling-boxes.launch was not found on this server. That’s all we know.

You have to manually install software to the eclipse, see http://code.google.com/p/rtm-ros-robotics/wiki/ROS_English#Setup_Eclipse Also check trouble shooting list. See http://code.google.com/p/rtm-ros-robotics/wiki/ROS_English#Troubleshooting

I already did manual install of software to Eclipse, but I followed the troubleshooting and did it again. When I did the first install of GEF SDK 3.6.2 i got these errors. iare these errors ok? sam@Mecha:~/prog/rtm-ros-robotics/rtm-ros-robotics/rtmros_common/openhrp3$ rosrun openhrp3 eclipse.sh I: Injected update sites

Comment by Kei Okada on 2012-05-25:
For a falling box example, java3declipse-20090302.zip and grxui_eclipse.zip are important. since you have trouble on opengl library, i suppose you'd better to reinstall the these eclipse plugins.

Comment by Kei Okada on 2012-05-25:
be sure that you have opengl properly installed by running glxgears and check if you can see "gears".

Comment by Kei Okada on 2012-05-25:
To reinstall the eclipse plugins, roscd openhrp3; make wipe; then run eclipse and remove insalled plugin (you can remove installed plugin from Help > Install New Software > already installed), roscd openhrp3; make; then install plugins again.

Comment by TurtleBot_Fan on 2012-05-25:
I redid all manual install with same bad result. I then did the following, but do not know how to continue with presented choices ?!: sam@Mecha:~$ roscd rtmros_common; svn up U hrpsys/launch/hrp4c.launch U hrpsys/Makefile.hrpsys-base Conflict discovered in 'hrpsys/index.rst'. Select: (p) postpone, (df) diff-full, (e) edit, (mc) mine-conflict, (tc) theirs-conflict, (s) show all options: What should I do? I did: sam@Mecha:~$ glxgears Error: couldn't get an RGB, Double-buffered visual If you meant to select a glxgears project .xml file, I didn't see one available.

Comment by Kei Okada on 2012-05-25:
select tc, sorry for inconvenience. we know this is the problem, but not fixed yet.

Comment by TurtleBot_Fan on 2012-05-25:
It's ok about inconvenience. I selected tc and then did: rosmake hrpsys hrpsys_ros_bridge and it completed without errors. I did all the troubleshooting, and seemed ok except I could never get any simulation graphics in 3d tab. I do not know what else to do. Everything seems to be working except for the 3D part of the simulation of falling boxes. One interesting side-effect from installing rtm-ros-robotics is my Matrix screensaver stopped rendering(!)

Comment by Kei Okada on 2012-05-25:
be sure that you have opengl properly installed by running glxgears and check if you can see "gears". If not you still have opengl problems. apt-get install --reinstall libgl1-mesa-dev libgl1-mesa-glx libglu1-mesa-dev

Comment by TurtleBot_Fan on 2012-05-26:
I did: sudo apt-get install --reinstall libgl1-mesa-dev libgl1-mesa-glx libglu1-mesa-dev sam@Mecha:~$ glxgears Error: couldn't get an RGB, Double-buffered visual Also did: sam@Mecha:~$ glxinfo | grep '^direct rendering:' Error: couldn't find RGB GLX visual or fbconfig Here are some interesting facts: 1- When first installing Ubuntu 10.04, OpenGL is automatically installed. 2- GLMatrix screensaver rendered fine before installing rtm-ros-robotics, now GLMatix screensaver does not render 3- After compiling 116 packages with zero failure and doing all troublingshooting steps, OpenGL is broken now, when it wasn't broken earlier. 4- Reinstalling OpenGL doesn't help for some reason 5- glxgears produces Error: couldn't get an RGB, Double-buffered visual 6- glxinfo | grep '^direct rendering:' produces Error: couldn't find RGB GLX visual or fbconfig 7- It will take me a long time to solve the OpenGL problem on my own since I am not a linux expert and will need to mine the internet for a solution

From previous post, it seems that you installed nvidia driver ant it conflicts with opengl from ubuntu. Can you uninstall nvidia driver ? how do you installed? check that /usr/lib/libGL.so and /usr/lib/libGLU.so symbolic links are correctly pointed ubuntu driver (mesa, not nvidia) as above comments

Comment by TurtleBot_Fan on 2012-05-26:
Also I found out that if I do: export LIBGL_ALWAYS_INDIRECT=1 then glxgears WORKS!! but the simulation still does not work and GLMatrix screensaver still not work. Newer versions of the GLX library favor direct software rendering over accelerated indirect rendering. I do not know how to make it work with direct rendering at this time.

Comment by TurtleBot_Fan on 2012-05-26:
I don't remember how I installed NVIDIA drivers or if I even did that.....too many years ago.

Comment by Kei Okada on 2012-05-26:
you have /usr/lib/libGL.so.275.21, that will comes from nvidia , dpkg -S libGL.so.275.21 to see who installed that

Comment by TurtleBot_Fan on 2012-05-26:
I did: sam@Mecha:/lib$ sudo dpkg -S libGL.so.275.21 dpkg: libGL.so.275.21 not found.

Comment by TurtleBot_Fan on 2012-05-26:
/usr/lib/libGL.so.275.21 is a SYMBOLIC link that must be changed to point at mesa right? If so, what is the command(s) to accomplish this symbolic link redirection? (I feel we are getting closer to solving this, thank you for your patience) Also did: sam@Mecha:~$ dpkg -s libGL.so.275.21 Package `libgl.so.275.21' is not installed and no info is available. Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents.

Comment by Kei Okada on 2012-05-26:
if dpkg -S XXX does not returns the answer (see dpkg -S libGL.so instead), this means that files (in this case libGL.so.275.21) should not exist.

Comment by Kei Okada on 2012-05-26:
/usr/lib/libGL.so -> mesa/libGL.so, /usr/lib/mesa/libGL.so -> libGL.so.1, /usr/lib/mesa/libGL.so.1 -> libGL.so.1.2, /usr/lib/mesa/libGL.so.1.2 (527200 byte). BTW how do you paste such a long message?

Comment by TurtleBot_Fan on 2012-05-27:
I'm confused about the /usr/lib/libGL.so.275.21 file not existing because it shows up in light green when I do sam@Mecha:~$ ls -al /usr/lib/libGL*. -----------To paste a long message I just copy the output in a terminal and paste it here. Then when I have more to paste later I do and 'edit'. What bothers me is that on my side all the words are strung together in a big sentence without any way to format them so it would be easier for you to read. If I try hitting the enter key to go to next line, the message gets submitted. What do we try now??

Comment by Kei Okada on 2012-05-27:
I'd like to make sure that you have /usr/lib/libGL.so.1. is it light? which I don't have. Please check if it will installed outside of ubuntu package system. if dpkg -S /usr/lib/libGL.so.1 returns error, you can remove /usr/lib/libGL.so.1 file

Comment by TurtleBot_Fan on 2012-05-27:

Comment by Kei Okada on 2012-05-28:
Oh, you used apt-file in the previous comment, that is not for finding a package in you system, but to find a package in the ubuntu repository. So, /usr/lib/libGL.so.1 -> libGL.so.275.21 is the starnge. dpkg -S /usr/lib/libGL.so.275.21 (not -s , but -S ) returns not found, you can remove the file,

Comment by Kei Okada on 2012-05-28:
You also better to remove /usr/lib/libGL.so.1, after checking dpkg -S /usr/lib/libGL.so.1. That file also did not installed from ubuntu system, I suppose.

Comment by Kei Okada on 2012-05-28:
after that, you can check by ldd which glxgears and that should show libGL.so.1 => /usr/lib/mesa/libGL.so.1 (0x00007ffd9aef3000)

Comment by TurtleBot_Fan on 2012-05-28:
Hey!!! I found the solution! It turned out, after a lot of digging, that I did manually install a proprietary version of an Nvidia display driver long ago when the Ubuntu 10.04 LTS was first released. Here is the solution for your future reference. ----1- When Ubuntu10.04 is initially installed, an open source display driver called Nouveau is automatically installed. 2- When installing a proprietary driver to use instead of Nouveau (in this case an Nvidia driver) it is best to do it as described at this URL: http://www.youtube.com/watch?v=Sh4ZmBdFCuU ----It is best to use the Ubuntu Software Center to install proprietary display drivers. If one chooses to bypass the Ubuntu Software Center by manually installing a proprietary display driver form the proprietary website, updates to the driver will not occur because the Ubuntu Software Center will not recognize the installation done outside the Ubuntu Software Center purview. Problems with conflicts (like the kind we had) will almost certainly occur later as a side-effect of not using the Ubuntu Software Center . 3- Used the Ubuntu Software Center to install NVidia binary X.Org driver (version 185) (not the latest version though) and all my OpenGL applications worked, but in indirect rendering only (which was bad because it's too slow). 4- I booted ny machine and then the direct rendering was enabled! ----------Thank you so much for your infinite patience and help. -------- Two side questiona:--Is there any documentation available for each of the simulations? Is there a way to have the simulation run faster?

Comment by Kei Okada on 2012-05-28:
Congratulations!, 1) Hope this page (http://www.openrtp.jp/openhrp3/en/users_manual.html) helps, you can speepd up the simulation by changing parameters in http://www.openrtp.jp/openhrp3/en/um_simulation_view.html. But basically this is slow due to precise dynamics simulation.

I would appreciate if you can summarise the debugging process as new the answerer post

Comment by TurtleBot_Fan on 2012-05-29:
For some reason, this forum interface is now limiting me to only about 300 characters and sometimes much less. There is something wrong with this forum interface. Is there anywhere else I can list the debugging summarization? I was able to insert a seemingly unlimited number of characters before...

Solution for: simulation of Falling Boxes not rendering

The debugging process:

1- Ensured that manual installation of eclipse software was done

1.1 see http://code.google.com/p/rtm-ros-robotics/wiki/ROS_English#Setup_Eclipse

1.2 Also check trouble shooting list. See http://code.google.com/p/rtm-ros-robotics /wiki/ROS_English#Troubleshooting

1.3 When installing GEF SDK 3.6.2 these errors ok sam@Mecha:~/prog/rtm-ros-robotics/rtm-ros-robotics/rtmros_common/openhrp3$ rosrun openhrp3 eclipse.sh I: Injected update sites

   failed
   * (Eclipse:3261): CRITICAL *: murrine_style_draw_box: assertion `height >= -1'
   failed

1.4 Did the following command sam@Mecha:~$ roscd rtmros_common; svn up

  U hrpsys/launch/hrp4c.launch U hrpsys/Makefile.hrpsys-base Conflict discovered 
  in 'hrpsys/index.rst'. Select: (p) postpone, (df) diff-full, (e) edit, (mc)  
  mine-conflict, (tc) theirs-conflict, (s) show all options: 
  (Select the tc option.)

2- Ran sam@Mecha:~$ glxgears

Error: couldn't get an RGB, Double-buffered visual If you meant to select a
glxgears project .xml file, I didn't see one available (now we know something is wrong with the display driver)

3- Used System->Preferences->Screensaver->GLMatrix to verify that GLMatrix would not render

4- Ran: sudo apt-get install --reinstall l freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev (to ensure the mesa software was installed properly)

Ran: sam@Mecha:~$ glxgears

Error: couldn't get an RGB, Double-buffered visual

Also ran: sam@Mecha:~$ glxinfo | grep '^direct rendering:'

Error: couldn't find RGB GLX visual or fbconfig

(problem is not mesa software)

5- Ran: export LIBGL_ALWAYS_INDIRECT=1

then glxgears WORKS! but the simulation still does not work and GLMatrix screensaver still doesn't work. Newer versions of the GLX library favor direct software rendering over accelerated indirect rendering

6- To see who the libGL files I ran:

sam@Mecha:~$ ls -al /usr/lib/libGL*

-rw-r--r-- 1 root root 487480 2010-01-17 00:07 /usr/lib/libGLEW.a

lrwxrwxrwx 1 root root 16 2012-05-23 17:03 /usr/lib/libGLEW.so ->libGLEW.so.1.5.2

lrwxrwxrwx 1 root root 16 2012-05-23 17:03 /usr/lib/libGLEW.so.1.5 ->libGLEW.so.1.5.2

-rw-r--r-- 1 root root 358456 2010-01-17 00:07 /usr/lib/libGLEW.so.1.5.2

-rw-r--r-- 1 root root 654 2011-07-29 03:02 /usr/lib/libGL.la

lrwxrwxrwx 1 root root 13 2012-05-26 10:23 /usr/lib/libGL.so -> mesa/libGL.so

lrwxrwxrwx 1 root root 15 2011-07-29 03:02 /usr/lib/libGL.so.1 ->libGL.so.275.21

-rwxr-xr-x 1 root root 1023120 2011-07-29 03:02 /usr/lib/libGL.so.275.21

-rw-r--r-- 1 root root 929838 2010-04-28 23:54 /usr/lib/libGLU.a

lrwxrwxrwx 1 root root 11 2012-05-26 10:23 /usr/lib/libGLU.so -> libGLU.so.1

lrwxrwxrwx 1 root root 20 2012-05-26 01:55 /usr/lib/libGLU.so.1 ->libGLU.so.1.3.070701

-rw-r--r-- 1 root root 461488 2010-04-28 23:54 /usr/lib/libGLU.so.1.3.070701

When the files were displayed only two were displayed in light green font:

/usr/lib/libGL.so.1 -> libGL.so.275.21 (this one is a symbolic link)

/usr/lib/libGL.so.275.21

These files have the version number of a proprietary installation of an NVidia display driver

7- I ran :

sam@Mecha:~$ dpkg -S libGL.so.275.21 (finds owner of package)

The result stated that the package did not exist. So now we know the Nvidia installation is invalid, so we can ignore it and proceed to install the NVidia binary X.Org driver (version 185) display driver available in the Ubuntu Software Center.

8- Ran: glxgears...and it worked.

GLMatrix screensaver... and it worked

OpenHRP Falling Boxes simulation....and it worked

They all worked, but were running slowly.

9- To see if OpenGL is using direct rendering or indirect rendering I ran:

sam@Mecha:~$ glxinfo | grep -i render

direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) OpenGL renderer string: GeForce GTS 450/PCI/SSE2

So, now we know we are using indirect rendering instead of direct rendering. If the OpenGL renderer string says "software" in it, then their drivers are not installed properly, even if direct rendering shows "Yes". Direct rendering is better because the rendering is faster.

10- Rebooted the computer.....and then ran:

sam@Mecha:~$ glxinfo | grep -i render

direct rendering: Yes OpenGL renderer string: unknown board/PCI/SSE2 GL_KTX_buffer_region, GL_NV_blend_square, GL_NV_conditional_render, GL_NVX_conditional_render, GL_NVX_gpu_memory_info,

11- Everything then worked properly and all was solved.
