I build my app with shared libraries. In my spec file, I source a

Below is how I proceed in my spec file:

%global _prod_dir /opt/intel/compilers_and_libraries_2016/linux
%global _mklroot_dir %{_prod_dir}/mkl
%global _mkllibpath %{_mklroot_dir}/lib/intel64_lin
%global _openmplibpath %{_prod_dir}/compiler/lib/intel64_lin
...............
%build
source /opt/intel/bin/compilervars.sh intel64
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:%{_mkllibpath}:%{_openmplibpath}:%{_builddir_full}/lib
..............
**************************************
make complains at one point about not finding one shared library:
/home/poisonivy/rpmbuild/BUILD/R-3.2.1/bin/exec/R: error while loading
shared libraries: libiomp5.so: cannot open shared object file: No such
file or directory
This library is indeed in %{_openmplibpath}. I conclude that
LD_LIBRARY_PATH has not been correctly populated in my build
environment.
Instead of guessing, make the %build section print it out so you can
check it:
echo $LD_LIBRARY_PATH
