Setup gcc — setup_gcc • devoptera

Set up a symlink to override xcode's clang with a valid version of gcc. If this doesn't work, first try following these instructions.

Usage

setup_gcc(
  version = "latest",
  link = "/usr/local/bin/gcc",
  sudo = FALSE,
  pass = Sys.getenv("PASS"),
  overwrite = TRUE,
  verbose = TRUE
)

version: gcc version to use (e.g. 7,8,9,10). If "latest", the latest version of gcc currently installed on your machine will be used.
link: The path or pathname of the link to be created. If "." (or NULL), it is inferred from the target argument, if possible.
sudo: Whether to run commands in sudo mode.
pass: Admin password.
overwrite: If TRUE, an existing link file is overwritten, otherwise not.
verbose: Print messages.

A data.frame listing all gcc versions, their paths, and which one is currently active.

if(interactive()) gcc_df <- setup_gcc(overwrite=FALSE)
