Just a clarification: With my system I use the latest intels version 10, 10.1.2.024, and mkl 10.1.2.024 because it proved difficult to make a debian package with version 11. At echo $LD_LIBRARY_PATH /opt/intel/mkl/10.1.2.024/lib/em64t:/opt/intel/cce/10.1.022/lib:opt/intel/fce/10.1.022/lib:/usr/local/lib (that /lib contains libimf.so) That results from sourcing in my .bashrc: . /opt/intel/fce/10.1.022/bin/ifortvars.sh . /opt/intel/cce/10.1.022/bin/iccvars.sh Did you suppress that sourcing before exporting the LD_EXPORT_PATH to the library at issue? Having so much turned around the proble, it is not unlikely that I am messing myself. thanks francesco > > Now I can run whatever programs need libimf.so without any problems.
