Hello, I have installed OpenFOAM-1.3 on my Ubuntu 6.06 LTS installation. I am using a Dell 490 box with intel XEON 64bit CPU's.

A little while ago I posted on here issues with getting FoamX to run on my Ubuntu installation and noted that the libelf files where already installed at /usr/lib.

When attempting to run FoamX i still get the following error.

Starting NameServer with inet:PhantomWorks:1234 ...
nsd: error while loading shared libraries: libelf.so.0: cannot open shared object file: No such file or directory

Now, I have searched through all the posts in this Installation folder on the discussion board and also looked at a number of posts on the FoamX folder as well. After this search, I attempted to disable SELinux but found it not to be installed. I also tried looking to see if SSH was installed and when typing which ssh i get /usr/bin/ssh.

I then type at my prompt and receive the following error.

lads@PhantomWorks:~$ ssh PhantomWorks
ssh: connect to host PhantomWorks port 22: Connection refused

I have then checked the firewall here in ubuntu (iptables):

lads@PhantomWorks:~$ sudo iptables -L
Password:
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination
lads@PhantomWorks:~$

Nothing is being blocked, let alone SSH. Why doesn't SSH work then? Why do I need SSH to work when I only want to run on a stand-alone box?


Now, I have run the two commands:

blockMesh . cavity
icoFoam . cavity

and had no problem what so ever in getting the solver to work. So as far as I can see I have no problem with my OpenFOAM-1.3 installation. I just can't for the life of me get this FoamX software to find the libelf.so.0 even though it is exactly where everyone here says it should be!!

I have installed the 32bit version of OpenFOAM-1.3. Initially when I first ran foamInstallationTest i had to set the directory path of the gcc complier location to

/home/lads/OpenFOAM/linux/gcc-4.1.0-64/bin/gc

for it to find my 32bit binary I downloaded with the OpenFoam software package. Is this strange?

The current foamInstallationtest gives the following output:

The system test has evoked 1 fatal error(s).

Critical systems ok.

Review the output for warning messages and consult the installation guide for trouble shooting.

Now, I am getting really frustrated with this software. I have tried everything, and am at the limit of my linux knowledge/expertise.

My group here at BOEING Australia are extremely interested in using this software and so I am now contemplating installing OpenSUSE 10.1 as no-one seems to have a problem once they download the libelf.so.0 from YaST.

Last time I posted, some gentlemen from Adelaide Uni where kind enough to reply to my post about these issues with FoamX, libelf and Ubuntu. Yet as far as I can see, they too do not use the FoamX GUI.

How can I learn OpenFoam without the GUI when all your tutes etc are using this FoamX GUI?

I am stuck.

Can anyone help?

Please.

Thanks for your time.

Regards

Hi Shaun,

For me it sounds like you have problems
with ssh not with OF. Can you use ssh
(not in FOAM)? read your foamInstallationtest
output carefully. you need to have either
ssh or rsh. ssh preferable because it is secure.

Second thing. You really do NOT need FoamX.
Even if you manage to install it, you will
drop it after several days of weeks(i bet).
It is limited. I dropped it after two weeks
and used it never again.

good luck,
rafal

ps third thing you in the output you can
also read that you do not have any mpi lib
set correctly(this also can say about problems
with remote shell). So far do not bother with
mpi but keep this in mind when you will need
to calculate something parallel.
parallel, but for now do not bother.

Hi,
I know nothing about Ubuntu but is your libelf.so.0 a 32bit binary? If I'm not wrong you need 32bit libelf.so.0 to run the 32bit nsd.

Basically it is preferable to install the 64bit version of OpenFOAM under a 64bit Linux. Since many of OpenFOAM users do so I think at least the probability of you getting any suggestion will be higher.

i didnt actually answer you questions

FoamX in only a front-end of OF in java. it works
like a server that connects to a maschine. This is
a reason why you need remote shell in FoamX and you
do not need in icoFoam.

You can learn everything without FoamX by typing
all commands in shell. if you know what you want
to do type a command in shell and output returns error and correct syntax (which you need).

Thanks to both of you gents for your replys. I will install the 64bit version of OpenFOAM and will ignore trying to use FoamX.

I am unsure if my libelf.so.0 is 32bit binary. I did install the amd64bit-generic version of Ubuntu.

I don't believe the MPI lib is an issue, as LAM is installed by default.

Thanks again.

So, Takuya, I installed the 64bit version of OpenFOAM 1.3 and guess what, FoamX worked straight away.

I guess your idea about the libelf being of 64bit form instead of 32bit was correct.

Thanks

When I run the command, blockMesh . cavity, I get the following error message.

blockMesh: error while loading shared libraries: libmeshTools.so: cannot open shared object file: No such file or directory.

Can someone help me with this? I just installed OpenFOAM 1.3 on AMD64 Opteron running SuSe Linux and am trying to test it.

Thanks.

Toni, I would suggest you have not installed the OpenFoam source code either properly or not at all.

Make sure your installation is correct and that you have installed in sequence the source code and binary files in the correct location.

See the readme file when you download OF 1.3

Did you set up the environment variable WM_64 to indicate you are running a 64-bit version?

Installation from binaries shoule be pretty straightforward, based on the README file.

Hi hamdi!

Havn't used FoamX in a long time, so I can only guess. The problem might be that nsd expects to find a libelf.so.0, but there is none on your system. Check with

ls /usr/lib/libelf*

which version are on your system. Then you might cheat with a symbolic link:

ln -s /usr/lib/libelf.so.0.97 /usr/lib/libelf.so.0

(use a version that exists on your system)

thank you Bernhard Gschaider for your help;
i do what you sugget :
when i type :ls /usr/lib/libelf*
it gives:
/usr/lib/libelf-0.120.so* (green color) /usr/lib/libelf.so.1 (blue color)

and when i type:
ln -s /usr/lib/libelf.so.0.97 /usr/lib/libelf.so.0
it gives:
ln: creation d'un lien symbolique /usr/lib/libelf.so.0 vers /usr/lib/libelf.so.0.97 : permission non accordée

(linux is in french version)
