How to specify the location of shared library when running a MPI program? #593

Closed xiongjie494 closed 7 years ago

xiongjie494 commented 8 years ago

I have run my MPI helloworld program succeed. Now I have another MPI program, named pvserver (ParaView Server), need to be run on cluster. When I execute the following command:

sgeadmin@master:~$ mpirun -np 2 ./pvserver

I got the errors:

/home/sgeadmin/ParaView-4.1.0-Linux-64bit/lib/paraview-4.1/pvserver: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

As a comparison, I run the program not using MPI as follow, it is success.

sgeadmin@master:~$ ./pvserver

That means the sequence program can find the shared library libGLU.so.1. So, my problem is how specify the location of shared library when running a MPI program? Could I pass some parameter about library location to the command 'mpirun'?

Thank you.

You can set up the LD_LIBRARY_PATH to point to the location of your libraries in your .bashrc. export LD_LIBRARY_PATH=/home/sgeadmin/ParaView-4.1.0-Linux-64bit/lib/:$LD_LIBRARY_PATH or set it it on the command line and pass it to mpirun

export LD_LIBRARY_PATH=/home/sgeadmin/ParaView-4.1.0-Linux-64bit/lib/:$LD_LIBRARY_PATH
mpirun -x LD_LIBRARY_PATH ....

Hi, vasisht, thank you for your help! But it seems the mpirun cannot accept the -x option. I am using mpich2. Is the -x is the option for openMPI, not for mpich2?

Thank you.

How can I do for the mpich2? Thank you.

It might easier just to set the LD_LIBRARY_PATH in .bashrc. That will carryover the enviroment variables.
