The configuration for compiling shared objects using R CMD SHLIB are set in file Makeconf. To change how the C++ code is compiled, modify this file. For RStan, package inline compiles the C++ code using R CMD SHLIB. To speed up compiled Stan models, increase the optimization level to -O3 defined in property CXXFLAGS in the file Makeconf. This file may also be modified to specify alternative C++ compilers, such as clang++ or later versions of g++.
