Hello ,
I have problems getting information from ParaView.
I have installed ParaView in foam-extend3.1 in Ubuntu 14.04TS, using AllMake.stage4 in ThirdParty directory.
When I try to read data from the display (find data via scalar value (v)), I get the error message: p, li { white-space: pre-wrap; } error: Find Data requires that ParaView be built with Python enabled. To enable Python set the CMake flag 'PARAVIEW_ENABLE_PYTHON' to True.


As AllMake.stage4 does not mention this flag, I do not know how to fix this.


Best regards,
Peter

I thouhgt I found the answer:
(http://www.cfd-online.com/Forums/ope...w-3-8-1-a.html)

but Allmake.stage4 (after running AllClean.stage4) is ready within a second, without error message, but I still can not use the button
Besat regards,
Peter

Greetings Peter,

I've had this on my to-do list for quite sometime now and I finally managed to look into this today. It seems that the following patch can solve this issue:

edit 2: OK, fixed the patch provided above. It should now work as intended, once this patch is applied.

edit 3: Oh for crying out loud... the option is not plugged in to anything... didn't work yet.

-----------------------

edit 4: OK, full patch is now in the code box above. I'm still testing this, but it should finally work as intended .
Note: The path "/usr/lib/libpython2.7.so.1.0" is the one I have for Ubuntu 12.04. Other library paths for other Ubuntu versions are available here: http://openfoamwiki.net/index.php/In...M-2.3.1/Ubuntu

edit 5: Confirmed. The latest patch in the code block above fixes the problem.

Hello Bruno,
Thanks for looking into this, however I now have the problem that AllClean.stage4 does not recognize the installed paraView version, so it is not uninstalled.
On another computer I have uninstalled ParaView via the Ubuntu Software Centre, when I then apply the AllMake.stage4, I get problems with unpacking of the archive: cpio mkdir failed - Permission denied
error ParaView-4.0.1-linux64GccDPOpt.x86_64: install failed
Done installing package.

Best regards
Peter

Hi Peter,

Uhm... I'm flying blind here... please describe in more detail how and where you've installed foam-extend 3.1, as well as what prerequisites you've installed, because it seems that you're using a less conventional installation than usual.

Best regards,
Bruno

[peterk]

Hello Bruno,
I don't know the details anymore. I deleted foamextend-3.1 and will reinstall it once again. Will keep you posted tomorrow or the day after.
Best regards,
Peter

[peterk]

Hello Bruno,

I have re-installed foamextend-3.1 using git from :
http://sourceforge.net/p/openfoam-ex...u/Ubuntu_14.04

Using paraFoam I get some errors on fonts.I don't know where they are comming from :

I am not able to delete ParaView with AllClean.stage4:
Then AllMake.stage4 (adapted according to your patch) does not change anything, see below:

I have tried with the previous installation to adapt AllMakeClean.stage4, in order to remove version 4 of ParaView, the file ran, but PAraView was still installed.


So far the findings with the new installation.

Best regards,

[wyldckat]

Hi Peter,

OK, the AllClean.stage4 script apparently is very outdated. Nothing like fixing the problem with one's own hands:

foam3rdParty
rm rpmBuild/RPMS/x86_64/ParaView-4.0.1-linux64GccDPOpt.x86_64.rpm
rm -r packages/ParaView-4.0.1/

And you should now be good to run the AllMake script!

In addition, my apologies, but I was so disoriented with not fixing the problem at my first couple of tries, that I ended up not uploading a tarball with the files that were modified. You can find them now in attachment, namely in "modified_files.tar.gz". Unpack it in the "ThirdParty" folder:

foam3rdParty
tar -xzf /path/to/modified_files.tar.gz

Best regards,
Bruno

Hello Bruno,
Sorry for keeping you busy, but first I got the error that the path to libpython2.7.so.1.0 was not found on /usr/lib.
I corrected this by the following command:

sudo ln -s  /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 /usr/lib/libpython2.7.so.1.0

When I ran AllMake.stage4 (the new one) after AllClean.stage4, the compilation stopped with following error (at 3%):

Hi Peter,

Ooops, sorry, I had only tested on Ubuntu 12.04. The symbolic link you've done does fix the initial problem, but you could have edited the file "AllMake.stage4" and fix said path

Please install the packages indicated here: http://openfoamwiki.net/index.php/In...u#Ubuntu_14.10 - in step #2. Those are, as far as I know, all of the necessary packages needed to build ParaView with Python support.

Best regards,
Bruno

[peterk]

Hello Bruno,
Strange, but these are different packages than described on the wikipage for installing (there a space was missing between the packages, I have made a tag for this).
I have installed all the packages mentioned under 2, including that for CGAL.

Hi Peter,

Can you please attach the full output log file "log.make"?

./AllMake.stage4 > log.make 2>&1

You can compress it with tar or gzip:

• gzip log.make

  Results in "log.make.gz".

• tar -czf log.make.tar.gz log.make

  Results in "log.make.tar.gz".

Best regards,
Bruno

Hello Bruno,
In a way we are now adding packages needed by OpenFoam2.3.1 to the ones as needed by foam-extend3.1. Can't this be a problem?
I can tomorrow try it on another computer, the one I tried today is a laptop.
Best regards,
Peter

[wyldckat]

The installation instructions currently available for foam-extend 3.1 are only meant for a fixed set of features.
As you've seen, we're trying to build new features that foam-extend 3.1 is not yet prepared to handle, which is why the modifications were necessary. On the other hand, I know from my own experience that those latest instructions for OpenFOAM 2.3.1 for Ubuntu 14.10 are able for certain to build ParaView with Python and so on. Which is why I requested that you'd install those packages.

My rough guess is that the problem your having right now is hidden somewhere above the output you've shown, which is why I was asking for the full log file. Specially because I don't have enough time to test this on Ubuntu 14.04 with foam-extend 3.1 and so on

[peterk]

Hello Bruno,
see the attached file, now only reaching 3% again, so I am afraid it could also be something in the hardware of the laptop

[wyldckat]

Ah HA! My intuition was right
Several lines above the final end you looked at, this can be found:

xmlpatterns: could not exec '/usr/lib/x86_64-linux-gnu/qt5/bin/xmlpatterns': No such file or directory

The solution is simple and is also already explained in the instructions for OpenFOAM 2.3.1: http://openfoamwiki.net/index.php/In...u#Ubuntu_14.10 - Simply run:

export QT_SELECT=qt4
./AllMake.stage4 > log.make 2>&1

Hopefully this fixes the problem

[peterk]

Helllo Bruno,
Thanks for all the effort, the compilation succeeded, but I have still to set somewhere the envronment variable to paraview: if I run a tutorial and start paraFoam, I get the error that paraview is not found, the command is there in :

Hi Peter,

Try starting a new terminal window, so that the shell environment is guaranteed to be updated.

And confirm if the following commands work as intended:

echo $PARAVIEW_BIN_DIR
echo $PARAVIEW_DIR
echo $PARAVIEW_INCLUDE_DIR
echo $PARAVIEW_LIB_DIR

which paraview

They should give something like this:

$ echo $PARAVIEW_BIN_DIR
/home/ofuser/foam/foam-extend-3.1/ThirdParty/packages/ParaView-4.0.1/platforms/linux64GccDPOpt/bin

$ echo $PARAVIEW_DIR
/home/ofuser/foam/foam-extend-3.1/ThirdParty/packages/ParaView-4.0.1/platforms/linux64GccDPOpt

$ echo $PARAVIEW_INCLUDE_DIR
/home/ofuser/foam/foam-extend-3.1/ThirdParty/packages/ParaView-4.0.1/platforms/linux64GccDPOpt/include/paraview-4.0

$ echo $PARAVIEW_LIB_DIR
/home/ofuser/foam/foam-extend-3.1/ThirdParty/packages/ParaView-4.0.1/platforms/linux64GccDPOpt/lib

$ which paraview
/home/ofuser/foam/foam-extend-3.1/ThirdParty/packages/ParaView-4.0.1/platforms/linux64GccDPOpt/bin/paraview

Best regards,
Bruno

[peterk]

Hello Bruno,
When I just add the complete path to paraview in the paraFoam file, then paraFoam starts and I the python is enabled, so I am still searching which environment variable has to be set. I can find it that quickly via google and the forum.
Best regards and goonight,
Peter

[peterk]

Hello Bruno,
This is the second time today, that our postings crossed in time.
I have removed the path in paraFoam. In a new terminal the environment variables are now ok.
starting paraFoam in the new terminal works well,
I only remember from the past that paraView opened directly supposing a OpenFoam file had to be read, now it opens with a menue of which one is openFoam.

Thanks once again for the effort: everything is working now
