which library provides libiomp5.so

[Sen Jia]

Hi,

When I run Gadgetron 3.7.5 with Intel MKL (CPU parallel computing was required), and without CUDA & CULA (GPU parallel computing was not required), I encountered the following error:

" DLL is missing (set LD_LIBRARY_PATH in UNIX) "

I checked the .so file in /usr/local/gadgetron/lib using

$ ldd gadgetronPlus.so, 

I got the result:

" libiomp5.so => not found ".

As I known, CULA & Intel Compiler both provides libiomp5.so. I tried to install CULA and set the LD_LIBRARY_PATH, and  the "DLL is missing" problem was solved. Just install Intel Compiler without CULA also solved the problem. 

 Is there any difference between the two libiomp5.so files provided by CULA and Intel Compiler separately? Which one should I use for using GtPlus? Or should the library to be a required dependency of Gadgetron?

Thank you.

Best wishes,

Jia Sen

It comes with MKL. Look in your MKL installation and make sure that you have the proper paths added.
