I just found the root of my issue. The LD_LIBRARY_PATH in my shell
environment was not correctly set. In fact, there are some issue in
the parallel_studio_xe_2016, with bad sylink who prevent to access
the correct path to the libraries. Once I corrected the path:
poisonivy@poppy ➤➤ ~/rpmbuild % ldd
/home/poisonivy/rpmbuild/BUILD/R-3.2.1/bin/exec/R
.....................
libiomp5.so => /opt/intel/compilers_and_libraries_2016.0.109/linux/compiler/lib/intel64_lin/libiomp5.so
(0x00007f4b8f7f9000)
The missing shared library is here. Nothing to do with my spec file
and build environment.
poisonivy@poppy ➤➤ ~/rpmbuild % echo $LD_LIBRARY_PATH
/opt/intel/compilers_and_libraries_2016.0.109/linux/compiler/lib/intel64_lin:/opt/intel/compilers_and_libraries_2016.0.9/mkl/lib/intel64_lin
