Either export PATH=/usr/local/clang4/bin:$PATH for general purpose of for R specifically in ~/.R/Makevars CC=/usr/local/clang4/bin/clang CXX=/usr/local/clang4/bin/clang++ The main difference is that clang 4.0.0 supports C++17 features and OpenMP -- neither of which is supported by Apple clang. > Or will this be "fixed" in the final release of R 3.4.0? There was just one fix - the path in Rcpp (and other C++ packages) should not have been /usr/local - it should point to libc++ in R - that has been fixed and should be available in the next nightly build. The libc++ was mistakenly not copied. > And just wait for the official release and package for R3.4.0? > No, please, keep checking the nightlies from http://r.research.att.com the release will be exactly the same, so we have to make sure we'll find all the bugs *before* there release so please keep testing and reporting.
