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… Benjamin Levy, Ph.D. > Begin forwarded message: > > From: Benjamin Levy <blevy...@icloud.com> > Subject: Installing Rcpp and working a compilation with C++ > Date: October 30, 2018 at 2:45:17 PM EDT > To: rcpp-devel@lists.r-forge.r-project.org > > Hello.
