[R] R install on silicon Mac lacks long.double capability
On my new macbook pro, I installed R using package installer R-4.5.1-arm64.pkg
My installation lacks long.double and libxml capabilities. How can these be
enabled?
My installation was in two steps:
1. Install Xcode developer tools (sudo xcode-select install), GNU fortran
compiler (gfortran-14.2-universal.pkg at cran), gnu readline, liblzma, and pcre2
(using macports), texlive, and Xquartz. Install R using above package
installer.
2. Source install.R from https://mac.r-project.org/bin/. In sudo R session,
run install.libs("r-base-dev"). Reinstall R using above package
installer.

[R] R install on silicon Mac lacks long.double capability
a) This belongs on r-sig-mac. b) Apple silicon does not support long double. Run an emulator for an architecture that does, or obtain another computer (e.g. cloud computing?) c) Don't use homebrew?
