[Rcpp-devel] Fwd: Installing Rcpp and working a compilation with C++

[Benjamin S. Levy]

In regard to my prior enquiry, I restored the ‘trusty’ to ‘bionic’ items in the sources.list; thank you for that tip.  Also, the [B artifact in my prior post was just from a carriage return between systems.  I have the location of the Rccp/include and .//libs per Listing 2.1, and am evidently still missing connection.  I spent some time with a Linux expert today, and he could not find the issue.  If there is a more recent link (I think it was cited), for help, I should be obliged.

With all due respect and much thanks, I am…

> I’m working with Dirk Eddelbuettel’s book and trying to conduct the first manual compilation with Rcpp (Listing 2.1).  I’m hitting a snag.  Here are the circumstances.  Perhaps the problem is my location of R in /usr/bin/ and the Rccp packages (and friends) in usr/local/lib/R/site-library/Rcpp?  I put the error message at the bottom, after the system-level detail.
