Hi!

I have installed OpenFOAM on a Suse linux 10.0 machine and it works fine, but paraFoam fails to start due to a segmentation fault:

/home/gaffu/OpenFOAM/OpenFOAM-1.2/bin/paraFoam: line 57: 1638 Segmentation fault paraview paraFoam.pvs

The installation test script gives no error:

I have paraview 2.4.2 installed in /usr/local/, can this create a conflict with paraview 2.2.0 installed in $HOME/Openfoam/linux/ ?

Any suggestions are welcomed!

You should check the LD_LIBRARY_PATH and make sure it is not conflicting with you paraview-2.4.2 version. Look into $WM_PROJECT_DIR/.OpenFOAM-1.2/apps/paraview/cshrc (bashrc).

For your information it is possible to compile OpenFOAM-1.2 with your own paraview-2.4.2, by making adequat modifications in the previous cshrc (bashrc) files and in $WM_PROJECT_DIR/applications/utilities/postProcessing/graphics/PVFoamReader/
You have to recompile the libvtkFoam and libPVFoamReader specifying a CMake-2.2.* installation.
I have successfully done it with paraview-2.4.2 and the current CVS paraview-2.5, on a Suse 10 box (both paraview and openfoam compiled with gcc-2.0.4).

Propably. If the parafoam-executable of 2.4.2 is found before the OpenFOAM-paraview (check with 'which paraview') you have this problem. Reorganize the PATH-variable in this case (the same is true for the LD_LIBRARY_PATH-variable for the dynamically-linked libraries)

Hi everybody !

I got a segmentation fault when running paraview. When I installed it last week, everything works, but since I use groovyBC, it doesn't work any more, even for (tutorial cases).

I recompile but no changes, and I try to debug it, (but I'm not a debugger at all !) :

The curious thing is that it says libpqComponents.so cannot open, but I check and it's present in /platforms/linuxGcc/bin and /platforms/linuxGcc/lib !

Is it a problem of path ?

Greeting Robin...

this is a really old thread...

Robin, can you please describe the following details:
  • What Linux distribution and version you are using.
  • What Gcc version or Icc version you are using.
  • What version of OpenFOAM you are using.
  • What version of ParaView and Qt you are using and whether they are custom builds or installed with the distro package manager (apt-get, yast, yum, zypper, ...).
  • When did it stop working, if it ever worked.
Otherwise, it'll be a long guessing game

Best regards,
Bruno

Paraview version 3.6.1 and i installed it along with OpenFOAM

It used to work properly but stopped working after i installed swak4Foam

But recently i found a work around. I go to this location in my computer :

/home/OpenFOAM/ThirdParty-1.6/paraview-3.6.1/platforms/linux64Gcc/bin and open paraview directly. only thing is i have to convert all files to VTK before postprocessing. Any ideas on how i can rectify the problem??

Sorry for the late reply

Hi Robin,

OK, a quick and dirty way to fix this is to edit the file "OpenFOAM-1.6.x/bin/paraFoam" and add the following line (the one in bold) right after the first block of comments:
Code:
# Description
#     start paraview with the OpenFOAM libraries
#
#------------------------------------------------------------------------------
export LD_LIBRARY_PATH=$ParaView_DIR:$LD_LIBRARY_PATH
usage() {
    while [ "$#" -ge 1 ]; do echo "$1"; shift; done
And this should do the trick!

The odd thing is that it stopped working after swak4foam was built... maybe this is one of those bugs that has already been fixed in more recent versions of swak4foam and OpenFOAM

Best regards,
Bruno

Hi Bruno,

What you said did not work. What is LD_LIBRARY_PATH ? which directory does it point to? i cd-ed it and it said this:
Code:
bash: cd: /home/bluesim/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/openmpi-1.3.3:/home/bluesim/OpenFOAM/ThirdParty-1.6.x/openmpi-1.3.3/platforms/linux64GccDPOpt/lib:/home/bluesim/OpenFOAM/ThirdParty-1.6.x/gcc-4.3.3/platforms/linux64/lib64:/home/bluesim/OpenFOAM/ThirdParty-1.6.x/gcc-4.3.3/platforms/linux64/lib:/home/bluesim/OpenFOAM/ThirdParty-1.6.x/gmp-4.2.4/platforms/linux64/lib:/home/bluesim/OpenFOAM/ThirdParty-1.6.x/mpfr-2.4.1/platforms/linux64/lib:/home/bluesim/OpenFOAM/bluesim-1.6.x/lib/linux64GccDPOpt:/home/bluesim/OpenFOAM/site/1.6.x/lib/linux64GccDPOpt:/home/bluesim/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt:/home/bluesim/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/dummy: No such file or directory
Thank you.

Quoting from wikipedia:

$LD_LIBRARY_PATH

On many Unix systems with a dynamic linker, contains a colon-separated list of directories that the dynamic linker should search for shared objects when building a process image after exec, before searching in any other directories.
As briefly explained in the above quote, LD_LIBRARY_PATH has a list of folders/directories to search for libraries; such library is the missing library "libpqComponents.so".

If the modification I wrote about in the previous post didn't work, then could you please check if:
  1. The variable "ParaView_DIR" has anything assigned to it? To see what it has, run:
    Code:
    echo $ParaView_DIR
  2. If anything was outputted from the previous command, then run the following two commands:
    Code:
    ls -l $ParaView_DIR
    ls -l $ParaView_DIR/libpqComponents*
    The first command will show you the contents of the ParaView folder and the second one will try to show you the missing library.
Best regards,
Bruno

Hi Robin,

You didn't post what the following command displays:
Code:
ls -l $ParaView_DIR
My guess is that I guessed wrong the folder where the library really is. Try this instead:
Code:
ls -l $ParaView_DIR/bin/libpqComponents*
If this shows the missing library, then edit once more the paraFoam file and edit it to look like this instead:
Code:
# Description
#     start paraview with the OpenFOAM libraries
#
#------------------------------------------------------------------------------
export LD_LIBRARY_PATH=$ParaView_DIR/bin:$LD_LIBRARY_PATH
usage() {
    while [ "$#" -ge 1 ]; do echo "$1"; shift; done
Best regards,
Bruno

With the edit that you suggested, it still shows segmentation fault. Thanks a lot for taking time to help me out.

Hi Robin,

OK, I guess that we'll have to try and to isolate the problem on the other side. You wrote before that things stopped working when you compiled/installed swak4foam, correct?
Then try renaming the folder "/home/bluesim/OpenFOAM/bluesim-1.6.x/" to something else. For example, run:
Code:
cd /home/bluesim/OpenFOAM
mv bluesim-1.6.x bluesim-1.6.x_tmp
Then try running paraFoam or paraview once again, to see if it still complains about the same problem.

If it still complains about the same problem, then it should be because you changed something else as well, when you built swak4foam.

Best regards and good luck!
Bruno

Don't think these two aspects have been discussed here. To my knowledge there are two ways for swak4Foam to 'break' paraview (it only plays libraries into $FOAM_USER_LIBBIN).

- Does paraview fail for all cases or only those where groovyBC is used? Try adding "libOpenFOAM.so" to the libs-list in the controlDict BEFORE libgroovyBC.so. Funnily enough this is only needed on Linux (not on the other OS with X in the end)
- Is it possible that some libraries ended up in $PV_PLUGIN_PATH (possibly because $FOAM_USER_LIBBIN is there)? Because then paraview will try to load them as plugins and fail miserably
