Hello everyone,

I've been trying to figure out my way around OpenFOAM 1612+ for several days now, (fresh Linux and OpenFOAM user here, so bear with me), so setting up my question will take a while, for which I'd like to apologize in advance.

First things first, this is not a critical issue, though I'm guessing it could come back to bite me in the a** in a few tutorials' time. These are my specs:
- OpenFOAM 1612+
- Ubuntu 16.04 (i686), running out of a Fujitsu Siemens with an intel Pentium Dual-Core

I've followed this installation guide as best as possible:
https://openfoamwiki.net/index.php/I...1612%2B/Ubuntu
The step-by-step description was really helpful, but the problems began as I started to build Paraview (step 9 of the aforementioned guide) [see log in attachment].

./makeParaView -python -mpi -python-lib /usr/lib/i386-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1

The process starts out OK but just freezes after 20-30min and then I have to force shutdown manually. Another occurrence was my system rebooting without warning and without finishing the build.
Pushing on with the guide, I proceeded to build OpenFOAM. After some trial-and-error, I figured that the core number specification in

./Allwmake -j 4 > log.make 2>&1

was no good for my setup. Having omitted it, I was able to go through with the install, system checks also good.
Now, as far as I can tell, I've successfully built OpenFOAM (both "blockMesh" and "icoFoam" are running smoothly].
At this point in time, this was my output for running "paraFoam" from the command line:

rui@rui-AMILO-PRO-V3515:~/OpenFOAM/rui-v1612+/run/tutorials/incompressible/icoFoam/cavity/cavity$ paraFoam

ERROR: ParaView reader module library (PVFoamReader) does not exist
Please build the reader module before continuing:

    cd $FOAM_UTILITIES/postProcessing/graphics/PVReaders
    ./Allwclean
    ./Allwmake

Created temporary 'cavity.foam'

And then nothing.
I tried the recommended solution:

rui@rui-AMILO-PRO-V3515:~/OpenFOAM/OpenFOAM-v1612+/applications/utilities/postProcessing/graphics/PVReaders$     ./Allwclean
wclean libso vtkPVReaders
wclean libso vtkPVblockMesh
wclean libso vtkPVFoam
rui@rui-AMILO-PRO-V3515:~/OpenFOAM/OpenFOAM-v1612+/applications/utilities/postProcessing/graphics/PVReaders$     ./Allwmake
==> skip build of ParaView plugins
    include directory was for paraview major version 'none'

Which I found weird, but couldn't find anyone else having the same issue out here on the forum, so I disregarded it.
Having no luck with the Paraview recommendations, I decided to build Paraview 5.0.1 directly from the site source (which isn't recommended for Ubuntu systems, as I've read). This worked to a limited extent. This is my output now:

rui@rui-AMILO-PRO-V3515:~/OpenFOAM/rui-v1612+/run/tutorials/incompressible/icoFoam/cavity/cavity$ paraFoam

ERROR: ParaView reader module library (PVFoamReader) does not exist
Please build the reader module before continuing:

    cd $FOAM_UTILITIES/postProcessing/graphics/PVReaders
    ./Allwclean
    ./Allwmake

Using the native VTK/OpenFOAM reader instead
Created temporary 'cavity.foam'

Which then opens Paraview with the correct case "cavity.foam".
Any thoughts on how to make the build better, or at least sidestep this error message?
Also, and I'm not sure if this is relevant, I haven't been able to correctly reboot or shutdown my system since installing the Ubuntu OS!

Your help is greatly appreciated.

Warm regards.
