SPACK and Intel Parallel Studio: „error while loading shared libraries:“

Spack is a package manager for supercomputers, Linux, and macOS. It makes installing scientific software easy. With Spack, you can build a package with multiple versions, configurations, platforms, and compilers, and all of these builds can coexist on the same machine.

However, when using the Intel Compiler as compiler, I got the following error for some packages:

 error while loading shared libraries: cannot open shared object file: No such file or directory

To solve this, edit your ~/.spack/linux/compilers.yaml file and set the extra_rpaths to your Intel Compiler libraries directory:

- compiler:
    environment: {}
    extra_rpaths: [/opt/intel/compilers_and_libraries_2018.1.163/linux/compiler/lib/intel64/]
    flags: {}
    modules: []
    operating_system: centos7
      cc: /opt/intel/compilers_and_libraries_2018.1.163/linux/bin/intel64/icc
      cxx: /opt/intel/compilers_and_libraries_2018.1.163/linux/bin/intel64/icpc
      f77: /opt/intel/compilers_and_libraries_2018.1.163/linux/bin/intel64/ifort
      fc: /opt/intel/compilers_and_libraries_2018.1.163/linux/bin/intel64/ifort
    spec: intel@18.0.1
    target: x86_64
