error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory

Question

I installed Intel® Parallel Studio XE Composer Edition for C++ Linux to use OpenMP 4.0. I compile example code with

icc example.c -openmp -o example

When I run ./example I have an error:

./example: error while loading shared libraries: libiomp5.so: cannot open shared object file: No such file or directory

Answer 1

With Intel compiler you should use -qopenmp.

Answer 2

In a HPC, I got the same message if I do not run module load intel firstly.

Answer 3

There is a dependency on the libiomp5.so module. Check to see if your machine already has this module installed by running $find / -name libiomp5.so and if the module is not found, then install it and put it in the modules folder that your program is looking in.
