Unable to install stringi R package on macOS M1 Monterey

I have been unable to install the R package stringi on my Macbook Pro (running MacOS Monterey) with the new M1 & arm64 architecture. There are a number of posts on SO describing similar problems, but the error message I’m receiving is something I haven’t seen before.

When I run install.packages("stringi") in RStudio, I receive the following error message:

stri_brkiter.cpp:60:9: error: use of undeclared identifier
    if (isNull(opts_brkiter)) {

I’m guessing there is some kind of compiler mismatch going on here, but I’m not sure what to make of that error message or how to fix the problem. I wasn’t able to find any examples online of others getting a similar message, either.

Note: The lines above are just the error portion of the message output. See below for full error text.

Warning message:
In install.packages("stringi") :
  installation of package ‘stringi’ had non-zero exit status

I’ve tried installing stringi Both in R Studio and on the command line, which some SO posts suggested may be more effective, but I receive the same errors via both methods.

Other commands I’ve tried (that did NOT fix it):

install.packages('stringi', configure.args="--disable-cxx11")
install.packages("stringi", configure.args = "--with-extra-cxxflags="--std=c++11"")

Fully removing my Makevars file didn’t resolve the issue.

I’ve checked many of the major/popular related questions on SO & Github (including this, this, this, this, this etc). I think I’ve reached the edge of my understanding of this stuff, though, and I’m not really sure what I could try next.

System info:

  • OS: Mac OS Monterey (v 12.2) w/ an Apple M1 Max chip
  • R: R version 4.2.0
  • RStudio: RStudio version 1.4.1717
  • Xcode: Xcode version 13.3.1
  • Installed gcc/gfortran and other libraries using Homebrew & added download location to $PATH

My Makevars file:

This file was built based on advice from here, here, here, and here.

CXX11FLAGS=-O3 -Wall -pipe -Wno-unused -pedantic

Does this error look familiar to anyone, or does anyone have suggestions of what I could do next to fix this? I’ve tried a lot of workarounds so I apologize if I’ve left anything out, please let me know if any other information could be useful!
