Wolle and Bruno, it was a execute permission problem and is fine now.

Thanks!

This setup allows me to compile and run my programs but I can't run OpenFoam solvers in parallel. In order to run in parallel OpenFoam I have to un-comment the aforementioned line in bashrc at .../OpenFOAM/OpenFOAM-1.6.x/etc/.

Is there an easier way to do that (swithcing OpenMPI installations) without needing to comment/un-comment lines in bashrc and the consequent sourcing of bashrc?

Yes, there is. Instead of always including the OpenFOAM .bashrc into your system .bashrc, add the following line:

alias startFoam=". $HOME/OpenFOAM/OpenFOAM-1.5/etc/bashrc"

Now, when you want to use OpenFOAM, just execute the command "startFoam" and the file will be sourced and the necessary settings should be applied.

Thanks akidess it seems to be a good idea.

http://www.cfd-online.com/Forums/ope...tml#post237867

And concerning the answer to Achims posting by akidess: I installed a brand new Xubuntu 9.04 yesterday and checked the RAM by the means of a complete Memtest86 run... no errors occured.

Wolle,

Did you ever get this fixed? I have the same problem: "internal compiler error" when trying to make wmkdep.

Any hints?
A.

Was it really your machine's RAM? I get an identical error and so did another user. Did you ever resolve the error?

[Wolle]

I'm sorry, but no, I haven't solved that issue yet.

As for me, I continue using the binaries until I get the first useful results for my project. If they're showing up, I'm going to get back to building my own version again.

But to answer your question: For OpenFoam I set up a completely new Xubuntu 9.04. As always when I set up a new OS, I checked the RAM with Memtest86+ just a few hours prior to the compiler error occurrence and no RAM errors occured while testing. So I don't think, that it's a memory issue.

At the moment I see 2 possible reasons:
1. I use Xubuntu 9.04 instead of Ubuntu at the moment. Next time I will use Ubuntu 9.10 again. What system are you using and on what machine?
2. Maybe LOCALES settings? In other threads, you can read about scripting issues with LOCALES settings that differ from English. As the compiler error occurs on my and Achims machine (and we're obviously both German speaking), I could imagine this as a possible reason - though it should not be... Maybe the programmers simply didn't care much about that? I have to admit: This is a very very very very vague guess!

Wolle,

I am running Ubuntu 9.04 (not Xubuntu). It is a fresh install just for the purpose of running OpenFOAM. My native language (Ubuntu and personal) is English. I am not expecting that to be the problem.

I couldn't find a package to install for Ubuntu using Synaptic. You must have found one for Xubuntu. Where did you find it?

Brian

[al3xand3r]

I got a problem in my OF installation. Reading all threads I didn't find what I was looking for. The most similar case is described by Aurel in the thread #41. But he had 2 critical errors, I got just his 2nd one. It's the same

First I chose to install from the binary file. I followed the wiki from 1.3 paragraph that should be my case. I really would like to avoid to compile all the files! If possible!
I am using Ubuntu 9.10 on 32bit machine.

After downloading files, unpacking them in my /home/gabriele/OpenFOAM/ directory I got this:

adding this line to the end of my /home/gabriele/.bashrc file

. $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc

typing

. $HOME/.bashrc

in the console and this is the result:

> . $HOME/.bashrc
>

So far it seems ok.
But when I run the test installation typing:

gabriele@gabriele-laptop:~/OpenFOAM/OpenFOAM-1.6/bin$ foamInstallationTest

this is the result:

Hi MadsR,

Thank you so much. I downloaded the script and successfully executed it. Subsequently I have tested openfoam installation and it is working great.

QUOTE=MadsR;228850]Hi there.

I am not sure if this helps anyone, but for what it's worth, I thought I'd share how I install OpenFOAM on a fresh Ubuntu 9.04 system in a somewhat fool-proof way...By installing I mean real install with compiling, not "only" downloading of binaries.

I have previously spent quite some time, installing OpenFOAM, so I was trying to simplify and organise the process. I like to bake cakes, so I'll put it in a cookbook way if that's okay with you.

1. you need to have a Ubuntu 9.04 system running (or a similar apt-get enabled distro)
2. you need to be logged in as the user you want to be using OF as (not just using su)
3. you need to be allowed to run the sudo command
4. download my install-script found here
5. read through the script and see if you find anything upsetting (please notify me if you do)
6. either - for the not so faint-hearted - run the script "automatically" by typing . ./installOF OR manually copy-paste each line from the script to your command-line and execute, a bit safer, the installation process step-wise
7. you could bake a cake now, as step 6 probably will take a really long time
8. enjoy OpenFOAM, a cup of coffee and your cake
9. if everything above worked out, you can actually maintain your OpenFOAM install by typing git pull in the OpenFOAM-1.6.x-directory followed by ./Allwmake

The script is "verision 1.0" - please use this at your own risk and don't hold anything against me if your summer-vacation pictures are deleted (actually if this happens I really wonder how my script could have caused that )

Let me know if this is useless, or if it helps you out.

Cheers,
Mads[/QUOTE]

Have a look here:

http://www.opencfd.co.uk/openfoam/do....html#download

Chose your platform and then download all 4 archives (OF Source pack, OF binary pack (double prec), Third party source, Third party binary). The unpack and follow README file. It's some 10 steps to get this working, not a big thing, really. And don't get confused with the package names... just because it's named "source pack" it doesn't mean, you'll have to compile it!

Cheers

HI, Mads,
I am really a beginner of linux, and have tried the way on the web of OpenFOAM, but I found it doesn't work.
Hope yours can help a me out of my troubles!
Best wishes!

HI,madrs,
I just completed the installation using your method, but there are two critical errors reported. This situation is the same with the way on the OF website. So, I dont know why. I followed the tips carefully. Anyway, please help me! Thanks a lot!

done.

[lglq]

good morning, madsr,
My problem seems different from others, when i run this command
. ~/OpenFOAM/OpenFOAM-1.6.x/etc/bashrc
There comes this warning:
Warning in /home/lglq/OpenFOAM/OpenFOAM-1.6.x/etc/settings.sh:
Cannot find /home/lglq/OpenFOAM/ThirdParty-1.6.x/gcc-4.3.3/platforms/linux installation.
Please install this compiler version or if you wish to use the system compiler,
change the 'compilerInstall' setting to 'System' in this file
So, with the next tips, after allmake, two ctitical errors were reported!
Hope you can help me!
ligang

[checkpalm]

lglq - concerning the first issue - version conflict - change OpenFOAM to System inside ~/OpenFOAM/OpenFOAM-1.6.x/etc/settings.sh ('compilerInstall' setting)
about the second issue - is "flex" installed on your machine?

[MadsR]

Hi Ligang.

First, is it Ubuntu 9.04 or 9.10? Is it 64-bit or 32-bit?

Also are the directories present? do an ls ~/OpenFOAM and check if ThirdParty-1.6.x is there and if the link ThirdParty-1.6 has been created. If not remove all and rerun the script.

The "system fix" noted by checkpalm can resolve some errors, but it shouldn't really be necessary. Flex should also be installed by the script.

Are you running a bash shell? (try doing a echo $SHELL)

A last "quick" fix (if you're just waiting around) is to remove the entire OpenFOAM directory and retry (rm -rf ~/OpenFOAM - careful with this command it's "powerful").

Keep on posting your progress!

/Mads

[lglq]

Hi, MadsR,
Thanks for your attention!
My OS is xp, but I use VMware to install a linux OS. which is Ubuntu 9.10, 32-bit.
I check the directories and find that OpenFOAM and the link have been created. I am running a bush shell.


ok, I removed the entire OpenFOAM and retry it again. And I will report the result here.
Best wishes!
Ligang

[lglq]

Hi, MadsR,
Thanks for your attention.
I just tried another script below. And it works, so maybe I just learn to use it. http://energy.tf.itb.ac.id/index.php...904?format=pdf
Anyway, really appreciate your help.
Wish you best.
Ligang

[MadsR]

Hi Ligang.

The "script" you refer to "installs" the binary version of OpenFOAM. This has been proposed as a "fix" earlier on in this thread, but it's actually not at all what we're trying to do with our script... ;-)

So, it's not really the same thing - it's installing OpenFOAM as a precompiled binary while we are providing a way of compiling OpenFOAM on your platform.

/Mads

[Caltech Brian]

Hi,

I am still getting an internal compiler error within the first couple lines of the Install Script on Ubuntu 9.04.

> flex wmkdep.l [finishes properly]
> gcc ... lex.yy.c [dies with an internal compiler err]

There seem to be several people with the same problem with no resolution. All of us have fresh installs of Ubuntu. All of us used the MadsR install script, which gets new (?) versions of all OpenFOAM, flex, ...

We are all using the recommended version of gcc.

Any idea where this error is coming from? Do we have environmental variables set wrong? Permissions (unlikely)? One user even suggested language settings (I am in English, he was in German).

Does everybody that compiles successfully get the warning regarding functions that are defined but not used? Is the problem in flex or in the compiler?

Brian

[akidess]

Brian, I'm not sure if this is something we can help you with, see http://stason.org/TULARC/os/linux-fa...ler-error.html

If you have the time, you could try compiling the newest version of gcc, and then using that binary to compile OpenFOAM and see if the error dissapears. If you just want to use OpenFOAM, I suggest using the binaries instead of compiling from source.
