libimf.so problem

Submitted by niqbal on Tue, 12/14/2010 - 15:27

Hi every one,
I am a new user of LIGGGHTS. I have installed it and working on it for a couple of weeks. Now when I am running my input script, it is giving me the following error.
"error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory"
What this libimf.so shared object is? Why it is missing now while every thing was fine a few days before?
I have tried to recompile it but is giving errors
Thanks in advance.

This seems to be a compiler problem, LIGGGHTS does not have lib dependencies except e.g. if you run with FFTs for solving electrostatic interactions on a grid or link to any of the libs in the /lib directory.
Ask your system admin

Hi Naved,
Have you installed mpi before installation LIGGGHTS? If yes then please search the lib file and put the whole path in the end of bash ( gedit /etc/bashrc for fedora) like this:

export LD_LIBRARY_PATH=/path of your lib

I think you can find the file in mpi directory.
It will work fine...
Cheers,
Ram

Thanks for your reply. I have figure it out by sourcing the files mentioned in the above post, Yes I have installed mpi before installation of LIGGGHTS during the installation of OpenFOAM, but every thing was working fine (LIGGGHTS+OpenFOAM+CFDEM). But I do not know what happened to the system (I could not figure out the reason) that the LIGGGHTS was giving me th above error. But now its ok.

Hi Christoph,
Thanks for your reply, I have solved the problem by sourcing the following files. (writing in my .bashrc file)
source /local/intel/bin/ifortvars.sh intel64
source /local/intel/bin/iccvars.sh intel64
Might be it will be helpful for some one encountering the same problem.
Regards,
