Compilation on intel compiler throws an error: "more than one instance of overloaded function"

[dfalster]

Compilation on a cluster platform using the Intel C compiler (icpc) is throwing an error. It's failing when compiling RcppR6.cpp:

compilation aborted for RcppR6.cpp (code 2)

Specifically, it's struggling with the to_string function at inst/include/plant/util.h(117).

Ok, Martin Thompson at UNSW solved the issue. The issue arose on the raijin cluster, so this fix is for that environment.

Martin says "that the Intel compilers still rely on some components from the GNU compilers, and the default GNU C++ compiler was too old to fully support C++11. So we need to load an environment module for any of the newer GNU compilers. As a consequence of that, we also need to slightly modify the order of directories where R looks for shared libraries."

This is achieved by adding into ${HOME}/.profile:

  module load gcc/4.6.4
  module load intel-fc/16.0.3.210
  module load intel-cc/16.0.3.210
  module load intel-mkl/16.0.3.210
  module load R/3.4.0

  if [ -n "${R_BASE}" -a -n "${GCC_BASE}" -a -n "${INTEL_MKL_BASE}" ]; then
      export R_LD_LIBRARY_PATH=${R_BASE}/lib64/R/lib:${GCC_BASE}/lib64:/usr/local/lib64:${INTEL_MKL_BASE}/lib/intel64_lin
  fi

Thanks Martin!
