I have already asked this question on stackoverflow, but it's also a linux related question and somebody here might know a solution. Hope it's okay.

Problem is that I can't run 3D visualisation in Paraprof program on ARM Linux. I am running a small cluster (8 nodes) using armhf Debian Wheezy 7.1 with OpenMPI.

I am using Tau OpenMPI profiling tool and it's got a very nice visualising tool called Paraprof.

I have a problem with 3D visualisation with paraprof. When I try to run it it says that:

/home/cluster/tool/tau-2.22.2/lib/libjogl_drihack.so :/home/cluster/tool/tau-2.22.2/lib/libjogl_drihack.so cannot open shared object: No such file or directory

I think it's a problem with libraries paths settings, because the path is doubled. Interestingly libjogl_drihack.so is in this directory. LD_LIBRARY_PATH is set correctly as:


OpenGL is installed (I can run glxinfo) and all libjogl packages.

Attaching screenshots. https://www.dropbox.com/s/x54xpo5c2kjzew8/tau1.png https://www.dropbox.com/s/mimze22pcl6vxkq/tau2.png

Some more info:

root@master:~# ldd
    not a dynamic executable
root@master:~# ls /home/cluster/tools/tau-2.22.2/arm_linux/lib/lib*.so
root@master:~# uname -a
Linux master 3.8.13-bone26 #1 SMP Fri Aug 16 20:56:24 UTC 2013 armv7l GNU/Linux


root@master:~$ glxinfo | grep OpenGL
OpenGL vendor string:Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 8.0.5
OpenGL shading language version string: 1.20
OpenGL extensions

The configuration script for Tau, was looking for libGL.so in /usr/lib directory, on my system this file is in /usr/lib/arm-linux-gnueabihf so i copied it to the /usr/lib, but still no luck. The same error persits.

Thanks for acknowledging your cross-post here, but you should have done it in the S.O. post too! –  goldilocks Oct 5 '13 at 14:33

    not a dynamic executable

This means what it says. It's one or more of:

  • Not a real .so file.
  • Not executable.
  • Compiled for a different architecture.

Check the output of file libjogl_drihack.so (you need the correct path there).

I'm not an openMPI or Tau user, but I notice there is a Tau package available for armhf Wheezy (or at least, there is for raspbian). However, I doubt this would install into /home/cluster, so evidently you are using something else.

If you compiled the whole thing on the system, this shouldn't happen either. But if you copied/built the binaries from somewhere else, that's your problem (note there is more than one ARM architecture). Do you have a reason for not using the distro package?

Compiled for a different architecture is probably right — it's probably an armel library on an armhf system. –  Gilles Oct 5 '13 at 14:46
Thanks, I'll try to recompile these libraries and we'll see if it works.. –  zdun8 Oct 5 '13 at 21:01
Recompiling jogl.1.0.0 is not so trivial on armhf as it would seem.. New jogl doesn't generate the files that I need unfortunately. –  zdun8 Oct 6 '13 at 0:19
