Racmacs install failure - /usr/local/bin/g++-11: No such file or directory

Hi!

I followed all your guidelines to install gcc through home brew and then generated a folder .R with the compiler file specified here: https://github.com/acorg/Racmacs

Here is the ERROR code that I get from R:

devtools::install_github("acorg/Racmacs")

(...)

I am not sure how to solve this issue. Please advise!

Thank you immensely in advance

There is now some updated info on setting up your compilation toolchain at acorg.github.io/Racmacs but you can also now install a pre-compiled binary version from CRAN with

install.packages("Racmacs")
