<div dir="ltr"><div>Hi all,</div><div><br></div><div>This is new and perplexing to me. I have an Ubuntu install of r-base, r-rcpp, etc. and have installed R-3.0.2 in order to maintain Bioconductor packages for the upcoming release. As of a few days ago, Rcpp stopped updating itself either via biocLite() or via command line installation. I forced /usr/lib64/R/library/Rcpp/lib into my library path, ran sudo ldconfig, set up environment variables that would seem to fix it e.g.</div>
<div><br></div><div>export LD_LIBRARY_PATH=/usr/local/cuda/lib:/usr/local/cuda/lib64:/usr/lib64/R/library/Rcpp/lib/<br></div><div><div>export PKG_CPPFLAGS=`Rscript -e "Rcpp:::CxxFlags()"`</div><div>export PKG_CPPFLAGS=" -I. -lpthread "$PKG_CPPFLAGS</div>
<div>export PKG_LIBS=`Rscript -e "Rcpp:::LdFlags()"`</div></div><div><br></div><div>but, alas, no joy:</div><div><br></div><div># ...everything going fine up to this point...</div><div><div>g++ -shared -L/usr/local/lib64 -o Rcpp.so Date.o Module.o Rcpp_init.o Timer.o api.o attributes.o barrier.o exceptions.o -L/usr/lib64/R/library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/lib64/R/library/Rcpp/lib -L/usr/lib64/R/lib -lR</div>

<div>* restoring previous ‘/usr/lib64/R/library/Rcpp’</div></div><div><br></div><div>Searching Google did not reveal anything obvious, and this is a very new problem (it has only arisen in the past week or so). Anyone have any suggestions?</div>
<div><br></div><div>I was blowing this off but realized that dplyr now depends on Rcpp-0.10.5 so now I have to bite the bullet. Again, I've never had any issues compiling Rcpp, and I haven't changed my R settings in a long, long time, so I wonder if something changed recently. Normally I can figure out these things but this time I'm stumped.</div>
