The issues I have had with R 3.4.0 RC appear to have mostly been resolved macOS El Capitan. (release candidate r72556 from http://r.research.att.com)
Many packages using Rcpp now do link to the libc++.1.dylib in the R framework. The following packages using Rcpp that I have installed are still linking to /usr/local/clang4/lib/libc++.1.dylib: dplyr e1071 forecast htmltools igraph lme4 NMF RandomFields RcppEigen readr reshape2 rgl roxygen2 RSpectra RSQLite scales sem spatstat testthat trustOptim That's 20 out of the 43 packages using Rcpp that I have installed. I have not checked all available packages using Rcpp. I always install binary packages. I don't really or urgently need to have clang4 installed so I would prefer all C++ using packages to link to the libc++.1.dylib in the R framework. The private package I referred to in previous mails works fine with Apple's libc++.1.dylib Berend _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
