[Rcpp-devel] problems using libc++ on ubuntu

| I?m trying to intall Rcpp using clang and libc++ instead of gcc and

Ubuntu happens to be my default setup -- but it managed to fsck up clang in
13.10 and 14.04. Luckily it now works in 14.10:

You should upgrade to 14.10, or just run (say) Debian in a chroot / Docker
container / virtual machine.
