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. > capabilities() jpeg png tiff tcltk X11 aqua TRUE TRUE TRUE TRUE TRUE TRUE http/ftp sockets libxml fifo cledit iconv TRUE TRUE FALSE TRUE TRUE TRUE NLS Rprof profmem cairo ICU long.double TRUE TRUE TRUE TRUE TRUE FALSE libcurl TRUE > sessionInfo() R version 4.5.1 (2025-06-13) Platform: aarch64-apple-darwin20 Running under: macOS Sequoia 15.4.1 Matrix products: default BLAS: /Library/Frameworks/R.framework/Versions/4.5-arm64/Resources/lib/libRblas.0.dylib LAPACK: /Library/Frameworks/R.framework/Versions/4.5-arm64/Resources/lib/libRlapack.dylib; LAPACK version 3.12.1 locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 time zone: America/New_York tzcode source: internal attached base packages: [1] stats graphics utils datasets grDevices methods base other attached packages: [1] latticeExtra_0.6-31 lattice_0.22-7 colorspace_2.1-2 loaded via a namespace (and not attached): [1] compiler_4.5.1 deldir_2.0-4 RColorBrewer_1.1-3 Rcpp_1.1.0 [5] interp_1.1-6 jpeg_0.1-11 grid_4.5.1 png_0.1-8 > nareshgurbuxani$ gfortran --version GNU Fortran (GCC) 14.2.0 Copyright (C) 2024 Free Software Foundation, Inc.
