R

System: Slackware Linux (version 15.0)
CPUs: Intel(R) Core(TM) i5-3230M CPU @2.60GHz
Deps: R-4.3.1.tar.gz

For PDF vignettes and package manuals to be rendered optimally you'll need the LaTeX package inconsolata or bera installed.

The previous Post is about the bera package.

The inconsolata package uses a slashed zero and some have commented its tilde is too high.

Set the variable R_RD4PDF=beramono to use the bera package when building R.

bash-5.1$ cat build.sh
#!/bin/bash

# Slackware build script for for R

PRGNAM=R
VERSION=${VERSION:-4.3.1}

if [ -z "$ARCH" ]; then
  case "$( uname -m )" in
    i?86) ARCH=i586 ;;
    arm*) ARCH=arm ;;
      *) ARCH=$( uname -m ) ;;
  esac
fi

if [ "$ARCH" = "i586" ]; then
  SLKCFLAGS="-O2 -march=i586 -mtune=i686"
elif [ "$ARCH" = "i686" ]; then
  SLKCFLAGS="-O2 -march=i686 -mtune=i686"
elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2 -fPIC"
else
  SLKCFLAGS="-O2"
fi

Set a default CRAN "repo" mirror.

The timezone workaround as of the configuration change (2020-12-09) is redundant.

For building certain external programs you may want to append $PKG_CONFIG_PATH.
