Troubles installing rsocsim on Mac (compilation)

[huentelb]

Hi Tom, I tried installing rsocsim for the first time, but received error messages (see console output below) and couldn't complete the installation. I use MacOS Ventura 13.4, RStudio Version 2023.06.0+421, and R 4.3.1. Also, I checked that I have devtools as well as Xcode (Version 14.3.1) installed and updated. Your help is very much appreciated! Thanks, Bettina

This is tricky. You seem to have installed all prerequisites, but R still can't "find the necessary tools to compile a package".

Can you try to run pkgbuild::check_build_tools(debug = TRUE) and post the output of that command here?

Hi Tom, thanks for your message. Here is the output you requested:

R finds a compiler (I guess), but it is maybe wrongly configured...

After some googling these are the steps I would try next:

• Try the (small) fix from this answer on Stackoverflow, although their problem was a bit different: https://stackoverflow.com/questions/70735301/rcpp-does-not-compile-on-mac-os-monterey-r-4-1-2-clang-error
• Follow this guide to remove a previous installation and then install the necessary compilertools for Rcpp (Rcpp is the library that rsocsim uses under the hood): https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/

Hi Tom, the problem was solved with the code from the first link! Thanks so much -- first simulation is already up and running now :))

That is great to hear!
