Dear all,

I try to run fluent 6.3.26 64 bit version in kubuntu 8.10 64bit and i get the following message ageorg@ageorg-desktop:~/Fluent.Inc/bin$ ./fluent /home/ageorg/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26 /home/ageorg/Fluent.Inc/fluent6.3.26/bin/fluent: 4677: domainname: not found /home/ageorg/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3 -f fluent (fluent " -r6.3.26 -path/home/ageorg/Fluent.Inc") /home/ageorg/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3: error while loading shared libraries: libstdc++.so.5: wrong ELF class: ELFCLASS32

Can anybody please provide me with some guidelines? What should i do?

Thanks very much in advance

maybe you should intall a vc++, which should be supported by 64 bit.

I had the same problem under SUSE11.1. I solved simply installing the library libstdc++33. I don't know but may be you have the libstdc++43 that provides libstdc++.so.6. Same problem also for Gambit with the library openmotif22-libs (in opensuse is installed 2.3).

It gives error about not found cortex.3.7.3, but I really have that file. Does anybody know what is happening?

When it comes to Linux, Fluent can only be run on either Red Hat, including Fedora or SuSE.

Hello vinerm,

Sorry but I do not know what Red Hat, Fedora and SuSE means.I will tell you the details of my problem:

I succesfully installed Fluent in my 32 bits ubuntu. When I execute Fluent I obtain this message:

/isabel@isabel-desktop:~/OpenFOAM/isabel-1.5/applications/solvers/mono52$ fluent
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent: 4677: domainname: not found
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent: 4677: /sbin/lspci: not found
/home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnx86/cortex.3.7.3 -f fluent (fluent " -alnx86 -r6.3.26 -path/home/isabel/Fluent.Inc")

And Fluent runs Ok.
Recently I changed to 64 bits ubuntu, I installed Fluent but when I try to execute it gives the following error:

isabel@isabel:~$ fluent
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent: 4677: /sbin/lspci: not found
/home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnx86/cortex.3.7.3 -f fluent (fluent " -alnx86 -r6.3.26 -path/home/isabel/Fluent.Inc")
/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent: 4715: /home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnx86/cortex.3.7.3: not found


The strange thing is that the file cortex.3.7.3 does exist and I do have it in "/home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnx86/cortex.3.7.3"

Is Fluent you installed on 64 bit machine a 64 bit version? That could be the issue. We use 64 bit machines and in their path, x86 is always replaced by x86_64.

This Fluent works Ok in linux 32 bits version, so I think it is not a 64 bits version.
Can I do something to install it in the 64 bits version of linux?

Hello lift86,

What version of Fluent are you installing, 32 bits or 64 bits?
And what version is your linux, 32 bits or 64 bits?

@lift86

Have you searched the Debian repositories ? They have a lot of stuff (binary compaible with Ubuntu), you may have a chance to find your libstdc++ library version.

Try to use the Ubuntu IRC chat on freenode, there are a lot of smart guys there, just ask about finding the desired library and where to find it.

Do

Ok, Dohander. But probably my problem is because I am trying to install a 32 bits fluent into a 64 bits ubuntu.

@isabel
Sorry my message was for lift86, my bad that I didn't mentioned this .

In your case, yes, this is the problem - however on a 64 bits machine you can install, if you want, a 32 bits Linux. You can create a separate partition on which you can install Ubuntu 32 bits and your 32 bits Fluent version.

The ideal solution will be to install Fluent 64 bits on your current machine.

Hello everybody,

I have installed Fluent 64 bits in my ubuntu 64 bits, but now I have the following problem:

/home/isabel/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26
/home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3 -f fluent (fluent " -alnamd64 -r6.3.26 -path/home/isabel/Fluent.Inc")
/home/isabel/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3: error while loading shared libraries: libstdc++.so.5: wrong ELF class: ELFCLASS32


So I have typed the following command:
sudo apt-get install libstdc++5
And I had the error It could not be found the packet libstdc++5


If I type locate libstdc++.so, I have the following:

/home/isabel/Fluent.Inc/fluent6.3.26/lnamd64/syslib/libstdc++.so.5
/home/isabel/Fluent.Inc/fluent6.3.26/lnamd64/syslib/libstdc++.so.5.0.3
/home/isabel/OpenFOAM/OpenFOAM-1.7.1/lib/libstdc++.so.6
/usr/lib/libstdc++.so.6
/usr/lib/libstdc++.so.6.0.13
/usr/lib/gcc/x86_64-linux-gnu/4.1/libstdc++.so
/usr/lib/gcc/x86_64-linux-gnu/4.4/libstdc++.so



Is the problem that I should have the library in /usr/lib/libstdc++.so.5 instead libstdc++.so.6?

If I type “ldd cortex.3.7.3” in my Fluent 32 bits with Ubuntu 32 bits I obtain this information:

isabel@isabel-desktop:~/Fluent.Inc/fluent6.3.26/cortex/lnx86$ ldd cortex.3.7.3
linux-gate.so.1 => (0xb7715000)

libXt.so.6 => /usr/lib/libXt.so.6 (0xb768c000)

libuuid.so.1 => /lib/libuuid.so.1 (0xb73b1000)
libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb73ac000)

As you can see, the library “libstdc++.so.5” is not found, but Fluent runs Ok.

Nevertheless, in my Fluent 64 bits in Ubuntu 64 bits, Fluent do not run without that library.
Does anybody know what I can do?

Yes, maybe I'll be able to help you. On the other hand, I manage with it on Ubuntu 10.10 (Maverick). I've just needed to work on Fluent+Ubuntu myself, and looking for solution of this problem, I've met this page.

First, add to yours ~/.bashrc following lines:
Code:
export FLUENT_ARCH=lnamd64
export FLUENT_INC=~/Fluent/Fluent.Inc
export FLUENT_LICENSE_FILE=$FLUENT_INC/license/license.dat
export PATH=$FLUENT_INC/bin:$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/villager/Fluent/Fluent.Inc/fluent6.3.26/lnamd64/syslib:/home/villager/Fluent/Fluent.Inc/lib3.0/lnamd64
Note, that I had my Fluent.Inc in /home/villager/Fluent. You have it in some other dir.

Second, I installed following packages:
gcc-3.3-base
cpp-3.3
gcc-3.3
libstdc++5_3.3.6-15

as it was recommended here for Ubuntu. I suppose, such packages can be found for Xubuntu too.

It's a key step. Fluent doesn't want to find libstdc++.so.5,
libhoops1127.so => not found
libdl.so.2 => /lib/libdl.so.2 (0x00007facb2ec9000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x00007facb2ca5000)
libXt.so.6 => /usr/lib/libXt.so.6 (0x00007facb2a3f000)
libXext.so.6 => /usr/lib/libXext.so.6 (0x00007facb282d000)
libX11.so.6 => /usr/lib/libX11.so.6 (0x00007facb24f7000)
libstdc++.so.5 => not found
though this lib is contained in /usr/lib (not? then
Code:
sudo apt-get install ia32-libs
).
It should be also noted, Fluent 64-bit needs libstdc++.so.5 that is 32-bit library, as well as standard x86_64 libraries.

Third,
Code:
sudo ldconfig -v|grep libstdc++
At last,
Code:
ldd -d /home/villager/Fluent/Fluent.Inc/fluent6.3.26/cortex/lnamd64/cortex.3.7.3
All packages should be found.

This way I managed to get through all errors, but the evening was lost. Hope, you will too.
