libirng.so: undefined symbol: __intel_avx_rep_memcpy for a mex interface

[utab]

Dear all,

I built the Fortran version of the sparse linear solver library MUMPS without problems. And the examples codes for the Fortran interface seems to work without problems.

However I am also interested in the MATLAB interface of the same library. Namely, I am trying the compile the MATLAB interface with gcc-4.7 since that is the supported compiler by MATLAB 2016.a. I provided the necessary intel runtime libraries or at least, I was thinking that I provided. The mex compilation process went fine without any problems however if I try to run the test codes related to the MATLAB interface, I am running into a problem with an undefined symbol, it seems that still I did not link all the necessary components. The error I am getting is as follows:

 .../linux/compiler/lib/intel64/libirng.so: undefined symbol: __intel_avx_rep_memcpy

What I am linking for the intel runtime libraries is provided below.

-L<path>/intel_parallel_studio_2016_2/compilers_and_libraries_2016.2.181/linux/compiler/lib/intel64_lin -lifcoremt -lifport -lirc -lsvml

Any ideas on how I can solve this problem are appreciated highly.

Best regards,

Umut

That should be found in libirc. Interestingly I don't see -lirng in your command line. Are you using ifort or ld to do the link?

To fix this problem, we just need to update libraries used by Matlab (very old one) with the latest from Intel.
