Dear Paolo

Thanks for your reply; it is the results of list dynamic dependencies
command for pw.x binary of QE (4.2) and QE (4.3.1) :

   Although the exact path of MKL libraries was included in .bashrc file, as
it is shown "libmkl_intel_lp64.so" and some other *.so files were not found
by QE (4.3.1).  In addition, I have copied the library files to /usr/lib and
for a test the code was configured with including the path of library
directory by LIBDIR. In all tries both QE (4.2) and QE(4.3.1) compiles well
but QE (4.3.1) could not find shared libraries such as libmkl_intel_lp64.so
and stopped. I appreciate your help in advance.


Best Wishes

 Masoud
