[R-SIG-Mac] Error when fitting a brms model, maybe associated with Catalina MacOS

JJB,

to be honest, what surprises me is why people don't use the most straight-forward way documented very explicitly in the installer which is simply


export PATH=/usr/local/clang7/bin:$PATH

I never touch Makevars as that is very error-prone and makes it impossible to use multiple R versions. CRAN is already configured correctly for those compilers so you should not need to do any manual overrides.

Cheers,
Simon

Sadly, the documentation for Makevars is not beginner friendly  and is scattered across multiple manuals [1][2] with the most precise explanation being off-site [3]. Moreover, many do not know about R's startup files [4], how to modify them, or where they exist as dot files are hidden by default [5].

The most successful approach taken was to provide as much of an automated process as possible while emphasizing the steps for those who wanted more depth.

Until that is the case or there exists a better approach, I'm more inclined to stick with the current approach I've taken especially as the macOS toolchain's stability changes on minor point releases (MAJOR.MINOR.PATCH). Again, these are made freely available to address an ever clearer need that is arising in the community.
