Subject: Compiling a library with Rcpp causing many 'unknown type'/'no member named' errors

Brian,
you are using Anaconda so all bets are off since that is not supported by CRAN. It looks like a broken compiler/runtime combination in Anaconda so your best bet would be to contact their support as this is unrelated to R (updating Anaconda sounds like an obvious first step, hoping the compiler/runtime issue has been fixed in newer version). I would recommend removing Anaconda and using released CRAN R version and Apple tools instead if you want a stable solution.
Cheers,
Simon

There are more details on this Stack Overflow post (https://stackoverflow.com/questions/77491429/compiling-a-library-with-rcpp-causing-many-unknown-type-no-member-named-erro) including the output errors.

However, I we were both unsure of how to direct R to use gfortran instead of anaconda, so he directed me to post to this mailing list. Could the compiler be the issue and if so, how do I switch to gfortran? Is there anything else that might be wrong?
