Hello, Hsiu-Khuern. All the times I have built, I've passed -std-gnu++11. Specifically, I pass: -march=native -O3 -mfpmath=sse -std=gnu++11 -msse2avx -mavx256-split-unaligned-load -mavx256-split-unaligned-store -mvzeroupper --param l1-cache-line-size=64 --param l1-cache-size=64 --param l2-cache-size=256. I live with the repeated warnings that it isn't needed for gcc, but I know it takes as I see the same string (gnu++11) passed when I build Rcpp from inside an R session.
