Hi, Recently I am using Condor (http://research.cs.wisc.edu/condor/) for parallel computing. I have an R package using RcppArmadillo and I followed the steps from http://chtc.cs.wisc.edu/MATLABandR.shtml to create my own RLIBS.tar.gz file for this use. However, when my submitted script running library(RcppArmadillo) I got the error message Loading required package: Rcpp Loading required package: methods Loading required package: RcppArmadillo Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/var/lib/condor/execute/slot1/dir_28295/RR/library/RcppArmadillo/libs/RcppArmadillo.so': libRcpp.so: cannot open shared object file: No such file or directory Failed with error: 'package 'RcppArmadillo' could not be loaded' I am not sure how to fix this problem. Thanks Bin
