Interesting. I tested the use of -O0, ..., -O3 together with -std=gnu++11. With -O0 (which I suppose is the default if not specified), I get the following error when R CMD INSTALL is trying to create Rcpp.dll: collect2.exe: error: ld returned 5 exit status With -O1, -O2, or -O3, there is no error. - Hsiu-Khuern ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
