@RorschachY I have had the same issue, were you able to overcome this at all?

Hi @RorschachY and @constancepopovic,

That looks like it's more of a Rcpp/Rcpp Armadillo issue than one specific to ExclusiveLasso : are you able to build other RcppArmadillo packages from source? Maybe try our clustRviz package or one of the reverse depends on CRAN? (If using CRAN, make sure you try to build locally and not download the pre-built tarball.)

I tried to reinstall Rcpp, and it resolved the issue.
