How to upgrade centFOAM
 

I have installed centFOAM early this May. How can I upgrade it to include OpenFOAM 2.1.1? Thanks.

Compile from source: http://www.openfoam.org/download/source.php

Edit: Alternatively rerun the centFOAM script. It has been updated to include OF-2.1.1 recently

Don't forget to update the centFOAM.py script first, by downloading the latest version from here: http://sourceforge.net/projects/centfoam/files/ ;)

Thank you Bruno and Anton!

when I input "blockMesh", the error comes

I know it means that the Application Binary Interface is non compatible between binaries used. How to fix this issue?

That's strange... what does the following command output?
If it does not output "x86_64", then that's the reason why you're getting that message.

yes, the output is "x86_64"

After you installed CentFOAM, did you modify anything in your personal "~/.bashrc" file?
Or better yet, did you change the reference from 2.1.0 to 2.1.1 or is there a repeated/similar line?

OK, what does this output:
This should give you a list of libraries to which blockMesh is expected to load.

Right. But I still dont know which ones are missing.

I forgot to indicate that this command will show what libraries it's expected to load and from where it will try to load them!
This way we can try to figure out if there are any 32bit libraries that it is trying to load!

Thanks.

No 32bit libraries were called.

Maybe it doesn't load any 32bit libraries, but then why is every single OpenFOAM related library being called from "OpenFOAM-2.1.0" and "ThirdParty-2.1.0" instead of the ones from 2.1.1?

Check in your "~/.bashrc" and see if you don't have more than one definition of "alias OF21"!? Because if you do, then you could/should:

1. Remove the first call to OF21, which is loading 2.1.0.
2. Rename the first "alias OF21=*" to "OF210", to avoid collision of definitions.

Then start a new terminal and try again!

Sorry, I just changed OF21 to call 2.1.0 and did not realized it when ldd $(which blockMesh) was run.

Now everything should be pointed to 2.1.1 and the output is

Mmm... weird... OK, let's try to use the ThirdParty folder from 2.1.0 with OpenFOAM 2.1.1:

Looks like GLIBCXX is missing.

OK, I'm guessing the GCC version used is different... try copying the GCC 4.6.2 build from 2.1.1 to 2.1.0:

If this doesn't work, check what GCC version OpenFOAM 2.1.0 is using: You can remove the "gcc-4.6.2" and create a symbolic link to it, e.g.:

Why do we need to copy the GCC 4.6.2 build from 2.1.1 to 2.1.0, if we try to make 2.1.1 work?

2.1.0 is using gcc-4.6.2.

Thanks.

Because according to the other error message, the library "libstdc++.so" was not being found, which is located at GCC's lib folder.
This is why I was specifying the need for copying the other gcc version, because its folder was not being found and "/usr/lib64/libstdc++.so.6" is being picked up instead.

I am getting the same problem with 2.1.1. Is there a known fix for this ?

Greetings Praveen,

I had to re-read the whole thread in order to understand you question :rolleyes:... so my question back to you is: did you try the instructions given along the thread? If so, what was the outcome?

You can also try building OpenFOAM 2.1.1 from the source code: http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

Best regards,
Bruno

I am having trouble even running ldd

I am on x86_64.

Hi Praveen,

Sorry, but I don't have time this weekend to try and replicate this error. As I wrote before, it's best that you re-build OpenFOAM from the source code. The link in the previous post provides instructions for both major versions of CentOS et al.

Best regards,
Bruno
