Building OpenFOAM 3.0.1 on Ubuntu 16.04 - failed
 

Hello!

I followed the steps here, which is where I download the source too, my system is a 64-bit Ubuntu 16.04, 16 GB RAM.

When I run ./Allwmake my build fails. It presents lots of errors instead of stopping on the first one, with the message : "undefined reference to `yyFlexLexer::yywrap" .

I did:

user@pc:~/OpenFOAM/OpenFOAM-3.0.1$ flex++ --version
flex++ 2.6.0
user@pc:~/OpenFOAM/OpenFOAM-3.0.1$ which flex++
/usr/bin/flex++

What am I doing wrong here?

Edit: also, is there a ppa available to install OpenFOAM without building on Ubuntu Xenial Xerus?

Quick answers:

1. To fix the problem, run:
   
   Code:

   ---

   #Go into OpenFOAM's main source folder
cd $WM_PROJECT_DIR
 
#Change how the flex version is checked
find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='

   ---

   Then try running Allwmake once again.
2. AFAIK, there is no PPA available for any OpenFOAM version :( I have been wanting to do this myself for quite sometime now, but setting up the Debian packaging folder isn't straight forward.
3. edit: I'm writing the detailed installation instructions here: http://openfoamwiki.net/index.php/In...u#Ubuntu_16.04

Thanks Bruno! Will try this as soon as possible!

I notice you answer most things here. I am still learning OpenFoam but been a linux USER for some time. How can one help with the OpenFoam project?

Quick answer: Good question! I didn't even remember that a forum sticky thread for this question big question was missing! I've quickly written it now and it's this one: http://www.cfd-online.com/Forums/ope...echnology.html

Let me add something to this. If you are using wmakeScheduler to compile, you will get the following error:

The solution is to install procmail:

When it prompts you to configure it, just select 'No configuration'.

Solution found in this thread: http://www.cfd-online.com/Forums/ope...oam-2-3-x.html

Best,

Pablo

Ok, using the code from Bruno it worked.

I used the same code on OpenFOAM 2.4.0 and could build it successfully on Ubuntu 16.04.

Then I went to build Paraview, but build failed at 13% building object vtkXOpenGLRenderWindow.cxx.o .

glxext.h 480:143 error: GLintptr has not been declared

Tried to follow the instructions here instead:

https://openfoamwiki.net/index.php/I...u#Ubuntu_16.04

But on step 8, using `./Allwmake > make.log 2>&1` gives me errors

I've attached the log.

Attachment 47047

Does the variable WM_NCOMPPROCS=4 matter AFTER building? If I didn't use it, in the 3.0.1 install, will OpenFOAM use 4 cores when running?

Quick answers:
You probably already solved this issue, but the fix for this is in step 9.2 here: https://openfoamwiki.net/index.php/I...u#Ubuntu_16.04

This is very strange, because I did a build of OpenFOAM 2.4.0 on Ubuntu 16.04 about a month ago and I didn't have any problems. Please try unpacking the ThirdParty-2.4.0.tgz file once again, for example, like this:
Then do step #8 once again.


"WM_NCOMPPROCS" is only used for building in parallel. It does not affect running cases in parallel or serial mode.

I was missing the ptscotch.h file when trying to build OpenFOAM on Ubuntu 16.04, so I had to install an additional package:

I still can't build, I created a script here called:

installOF240_sh.txt

if someone could be kind enough to give me a script to just run and install Open FOAM 2.4.0 in Ubuntu 16.04 I would be very happy.

Tried everything and it just doesn't build.

I could build with no problems Open FOAM 3.0.1.

If there is a .deb package that works or a PPA please, tell me!!!

@erico: OK, the problem with CGAL can be ignored. I still don't understand what's going on wrong, but this can be ignored for now. I'll have to review the instructions to use the CGAL version that comes with Ubuntu 16.04, which should solve this problem.


If you still have OpenFOAM-2.4.0 in your build structure, then please simply try run the following commands and you should get at least most of OpenFOAM built and up and running, although foamyHexMesh won't be working (edit: see the next post as well):

If you want the complete script, it's easier for me to post the code here (edit: updated script code based on findings shown in the next post):
At the end, check the contents of the file "log.make". If there are problems, please attach the file "log.make.gz".

Sorry about the confusion. I've solved the problem with CGAL. Quoting myself from a few minutes ago:
I've also updated the big chunk of script code in the previous post.

so wmSET didn't work.

I understand that using source $HOME/OpenFOAM/OpenFOAM-2.4.0/etc/bashrc WM_NCOMPPROCS=4 is ok - as alternative to the wmSET command that is inexistent on my system.

Anyway, now I have a different problem. Damn, I really wish OpenFOAM was just packed somewhere, maybe as Snaps, or as debs or a ppa...

I have zero results for this error in Google.

EDIT: I am an idiot. The correct software is paraFoam. Nevermind, everything is working. It's perfect.

Unable to install OpenFOAM in ubuntu 16.04
 

As per the instruction, I tried running
But I received the following message
Could someone please tell me what to do as I am new to Ubuntu and OpenFOAM?

Thanks

Quick answer @RishabhG: Sorry, I completely forgot to add to the instructions on the wiki for updating the apt-get cache.

On the terminal, in root mode, please run the following command:
Or if you're on the terminal as a normal user, try:
Then try following the instructions once again.


edit: I've updated all of the wiki pages I could remember about on this detail.

OpenFoam Tutorial
 

Thanks a lot. I was able to successfully install

I was trying a tutorial given in http://cfd.direct/openfoam/user-guid...ty/#x5-40002.1

This seems legit as the screen shot below shows no cavity file/folder within the cavity folder. So is there a mistake in tutorial or am I missing something?

Quick answer @RishabhG: I'm guessing that you started a new terminal window or tab. You need to run the respective alias command. In your situation, where you have OpenFOAM 3.0.1, run:
to activate the OpenFOAM environment on the terminal (command line).

If that gives you an error message, then something went wrong. Please let me/us know of what error message it gives you or check the installation instructions again, namely the step that uses the command "source", which at the current time of writing is step #8 here: http://openfoamwiki.net/index.php/In...u#Ubuntu_16.04

I did run the of301 command. The I ran
Followed by I received the following
Probably there is some mistake in command as it says what to copy but not where to copy. Could you please help me out

Quick answer: Oh, OK, not I can see what the problem really is. THe error message is telling you this:
This means that the target location is missing from the address. For example, the command expects this:
where:

• "origin" is this path:
  Code:

  ---

  $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity

  ---

• and the "target" is this meant little dot:
  Code:

  ---

  .

  ---

In your the previous post, the dot was there:

But on the post you made now:
See? The dot at the end of the command line is missing!


Maybe this is easier to see:
It's the same, it's just that this makes it a bit easier to spot the dot at the end and the slash "/" is an indication of the directory (folder) to which the dot refers to.
